Boat Navigation Lights Rules: Illustrated Beginners Guide

When navigating at night, the lights on other boats are your first clue about the moving dangers around you. And your navigation lights are your first line of safety in avoiding collisions in the dark, and they tell others vessels what you are and what you are doing. The rules sound complex, but with a little understanding you can get the basics for any situation.

So what are the basic navigation light rules? For most small vessels, motoring requires red and green (port and starboard) lights, and a white light visible in all directions around the boat. This is almost always a stern light and a masthead light on sailboats. Boats under sail require port and starboard lights, and a white stern light. Sailboats below sixty-five feet may show a tricolor light at the masthead instead of side and stern lights when sailing.

That's it, in a nutshell. There's a little more to it, as the rules change with different sizes and there are some specifics about angles of display for the colors. Identifying other ships at sea requires more study, but the basics are the same. And it's not much trouble to make sure you've always got the proper lights on your vessel.

Infographic for Marine Navigation Lights Rules based on sailboat size

On this page:

What are the official colregs rules for your sailboat, what about the uscg (united states coast guard) rules, lighting at anchor, identifying the boats around you.

The International Regulations for the Prevention of Collision at Sea , abbreviated "COLREGS" is very specific about the lights required, their shapes and sizes, and the distance they must be visible. For the smaller boat, the following definitions apply.

  • Masthead Light - a white light placed centerline on the boat showing an arc of 225 degrees with 112.5 degrees either side of the front of the vessel.
  • Sidelights - A red light on the port side and a green light on the starboard. They must show an arc of 112.5 degrees from centerline of the bow.
  • Stern light - A white light on the stern of the boat showing an unbroken arc of 135 degrees from centerline of the vessel.
  • All-round light - A light showing in an unbroken arc of 360 degrees.

The good news is you need not measure these angles. Any properly installed USCG or COLREGS approved light which will cover the correct arcs. If you have to replace the original light from your boat, make sure it's with an approved replacement.

Lights When Sailing

picture of a properly lit sailboat at night

The specific rules for a sailboat under sail are in COLREGS Rule 25 and vary slightly with the size of the boat. A sailboat powering is considered a power boat and falls under in Rule 23.

  • Under 23 feet (7 meters) - side lights and a stern light, possible. If these lights can not be displayed a light must be kept at hand to help avoid a collision. This can be a bright flashlight.
  • Over 23 feet - Side lights visible to one nautical mile and stern light visible for two.
  • Vessels under 65 feet may combine both sidelights into a single lantern on the bow.
  • May show a tricolor light on the masthead instead of sidelights and a stern light. It's one or the other though, do not show these lights at the same time .
  • Masthead light must be visible for three nautical miles, all other lights must have a two nautical mile visibility.
  • Side lights must be separated.
  • May not show a masthead tricolor light.
  • Masthead light must have five nautical mile visibility, all other lights must be visible for two nautical miles.
  • Optional masthead lights - any vessel under sail may display a red light over a green light at the masthead with sidelights and stern light. The red over green may NOT be displayed with a masthead tricolor light. It's one set or the other.

Lights When Motoring

picture of a properly lit sailboat at night

For all navigational purposes a sailboat under power is considered a power boat. This includes motor sailing - if the engine is on and providing propulsion you are on a power boat, even if the sails are up . This applies to navigation lighting, sound signals in fog and limited visibility, and rights of way.

Sailboats under 50 meters under power need to show:

  • A masthead light
  • Stern light

A power-driven vessel under 23 feet (7 meters) that does not exceed seven knots of speed may display an all around white light, though sidelights should be used if available.

picture of a properly lit sailboat at night

The USCG has published its own "Rules of the Road" that are based on the COLREGS. In addition, it has rules for the "Inland Waterways" for rivers, inland lakes and the Great Lakes.

The good news is this has no impact on what you have to do with your own boat.

They mostly relate to lighting changes on towed vessels like barges and tugs. For example, a vessel towing or pushing another vessel in the ocean under COLREGS shows two masthead lights, sidelights and a stern light, whereas in Inland Waterways the towing or pushing vessel displays two yellow towing lights instead of a white stern light.

If you sail on lakes, rivers or the Great Lakes where towed commercial traffic is common you should learn the inland lights, but coastal or ocean sailors will never see these.

When you anchor outside a designated mooring field, you should display an all around white light at the masthead or as high in the boat as practical.

picture of a properly lit sailboat at night

If your boat is large and has a very tall mast, you may wish to display another light closer to the waterline. Boats approaching in the dark may not see a light on a mast sixty or seventy feet in the air when they are close to your boat.

We use a simple garden path light on our stern when we anchor, left in a rod holder or flag socket. It comes on automatically at dusk and is a cheap and easy way to be more visible. There is no specific rule stating you can not display more lights than required, or the nature of any lights beyond the required all around light.

The COLREGS also specify that a round black "daymark" should be displayed in the rigging of any vessel at anchor. Very few small vessels observe this, however it is the correct display for a vessel in an anchorage.

If you tie to a mooring in a marked mooring area you are not required to display anchor lights, but there is no harm in doing so.

The other important reason to know your lights is to figure out what's going on around you at night. The water may be ablaze with white, red, green and other lights at night and they are your first key to avoiding collisions and problems.

All combinations of lights for fishing boats, commercial vessels, and so on are outside this post‘s scope. The odds are small you will encounter a submarine, seaplane or hovercraft at night, but there are regulations regarding specific lighting for each of those vessels!

There are a few fundamentals to help you figure out what that is you see on the horizon, which way it is going, and whether it is a danger to you.

Port Wine is Red

The fundamental rule is that red sidelights will ALWAYS be on the port side of a vessel, and green lights will always be on starboard. However, some vessels can use all around red and green lights for other purposes, though those will be higher than sidelights.

Diagram for identifying boats at night

The light‘s on a ship is not important, some large tankers and freighters will have their sidelights far aft and put them on the superstructure for better visibility. It is not safe to assume that sidelights you can see are on the bow of large vessels .

When you can see the color, you know which way the bow is pointing. If it's red, it's pointing more or less to the left and will travel in that direction. A green light shows it is heading more or less to your right.

If you can see the red and green lights at the same time, you are looking directly at the bow of the vessel. When you are far away, this isn‘t as alarming as if you are close crossing. Seeing red and green lights together on a vessel is something you never want to see for long.

Be aware of red and green lights used in combination with other red, green and white lights. These may not be running lights and could have other significance.

Tankers, Freighters and Large Ships

Tankers, freighters and large ships will have side lights, a stern light and a masthead light. In addition, on vessels over 50 meters there will be a second masthead light further aft and higher than the forward light. The masthead light positions are a better tipoff to the bow direction and how far from the bow the sidelights might be. Remember - on a large vessel the sidelights may not be at the bow or even close to it.

USCG Inland Rules allow for a second all-around white light on large vessels on the Great Lakes instead of a second masthead light.

Fishing Boats

Fishing boats engaged in fishing will have more complex light displays. When they aren't fishing, they will show lights like any power vessel, but Rule 26 spells out light combinations that vary by the fishing activity being done. In general:

  • Boats which are Trawling but not making headway will display a green all-around light over a white all-around light , and a masthead light aft of these lights. Boats making headway while trawling will show these lights, plus sidelights and a stern light.
  • A vessel fishing other than trawling will show a red all-around light over a white all-around light . When making way they will also show sidelights and a stern light.
  • If a vessel has gear more than 150 meters away from the boat, it will show a second all around light in the direction of the gear. The best rule is to give fishing boats as wide a berth as you can at night. They're easy to pick out if you check the top light configurations but their course may be difficult to predict.

Towing and Pushing

Towed vessels can be the most dangerous to cross, but they have the most lights to tell you what is happening. Refer to COLREGS or the USCG Rules of the Road Rule 24 for all combinations You can pick a tow/push vessel out with the following lights:

  • Two or three masthead lights in a vertical line. Three masthead lights shows a tow over 200 meters. Additional masthead lights may show for larger tow vessels.
  • A towing light (yellow light with the same characteristics as a stern light) directly above the stern light.
  • The will also have side lights and a stern light.
  • The towed vessel will show sidelights and a stern light. Lighting may vary under USCG inland rules, where towing lights may replace stern lights. Learn these differences if this is your regular cruising ground. If you think there is a tow ahead of you, always go well behind the aft most set of lights. Never go between a tow and avoid crossing ahead if possible as it may restrict their maneuverability.

Special Situations

There are several rare situations you may encounter. As a general rule, if there are a lot of lights and you don't understand them look for the sidelights on a moving vessel. If you can find them and figure out the direction it is moving, it makes the vessel easier to avoid. Stay well clear of lights you do not understand if you can avoid them without risk.

Most of these signals are used by larger, commercial vessels and you will not need them.

They use these light combinations with other light combinations. For example a towing vessel may also be restricted in maneuverability, and a vessel constrained by draft will show running lights if moving.

  • Not Under Command - two all around red lights in a single line
  • Restricted in Ability to Maneuver - red, white then red in a single line
  • Constrained by draft - three all around red lights

2. What are the different types of navigation lights found on a sailboat? Sailboats typically feature three main navigation lights: red (portside), green (starboard side), and white (stern light). The red light tells other sailors that your boat’s portside is facing them, while the green light indicates that your starboard side is visible. The white stern light illuminates the rear of your vessel, making it easier for others to determine your direction of travel.

3. When should I turn on my sailboat’s navigation lights? According to international rules of collision avoidance at sea, all vessels must show proper navigation lighting between sunset and sunrise or during periods of restricted visibility such as fog or heavy rain showers. It’s essential to remember that even during daylight hours if visibility drops due to poor weather conditions, switching on navigational lights can greatly enhance safety.

4. Are there any additional requirements regarding sailboat navigation lighting? Yes! Aside from displaying the three main distinct navigation lights mentioned above, it is crucial for sailboats under power or motorsailing – using engine power alongside sails – to display an additional white forward-facing masthead light apart from the stern light. This masthead light helps identify the sailboat as a power-driven vessel, providing further clarity to nearby boaters.

5. Can I use LED lights for navigation purposes on my sailboat? Absolutely! In fact, LED lights are highly recommended for their energy efficiency and prolonged lifespan compared to traditional incandescent bulbs. However, it is essential to ensure that any LED navigation lights you use adhere to relevant maritime regulations concerning color, visibility range, and intensity.

6. How can I check if my sailboat’s navigation lights are working correctly? Regular maintenance and testing of your navigation lights are vital to guarantee their functionality when needed the most. Before every outing, visually inspect each light for signs of damage or corrosion. Additionally, switch on all navigational lights while docked or at anchor to verify they illuminate brightly according to the appropriate standards laid out in navigational lighting regulations.

Conclusion: Understanding sailboat navigation lighting not only ensures your safety but also promotes effective communication with other vessels on the water. By knowing when and how to properly utilize these lights, you contribute to maintaining a harmonious sailing environment. Remember, navigating with wit means being informed and cleverly enhancing your skills as a sailor while keeping safety at the forefront of your adventures!

Always carry spare bulbs and fuses suited for your specific lighting system to avoid such predicaments and keep your journey uninterrupted.

7. Stay Familiar with Navigation Regulations: Being updated on marine regulations regarding navigation lights is not only essential for your safety but also ensures compliance with local laws. These regulations dictate the placement, colors, and timings for displaying navigational lights based on different conditions such as underway, anchored, or sailing near other vessels at night.

In conclusion, maintaining sailboat navigation lights might seem like a mundane task; however, its significance cannot be undermined when it comes to safety during nighttime voyages. Regular inspections, adequate power supply, LED technology adoption, cleanliness, moisture protection, carrying spare bulbs/fuses, and adhering to maritime regulations should become second nature for any seasoned sailor. By following these top tips and best practices meticulously, you’ll be able to navigate the vast expanse of dark waters with confidence while ensuring a safe voyage each time.

Exploring Different Types and Designs of Sailboat Navigation Lights

When it comes to sailing at night, having the right navigation lights on your sailboat is absolutely crucial. Not only do they help you stay safe and avoid collisions with other vessels, but they also ensure that you are compliant with maritime regulations. In this blog post, we will be exploring different types and designs of sailboat navigation lights, so you can make an informed decision for your own vessel.

One of the most common types of sailboat navigation lights is the sidelight. These lights are usually mounted on either side of the boat and emit a green light on the starboard (right) side and a red light on the port (left) side. The purpose of these lights is to signal the direction in which your boat is moving to other vessels in the vicinity. Additionally, sidelights should be visible at a distance of at least two nautical miles, ensuring that other boats have ample time to react accordingly.

Another important type of navigation light for sailboats is the sternlight. As its name suggests, this light is mounted at the back or stern of the boat and emits a white light. The sternlight helps other vessels determine if you are moving away from them or approaching them from behind. It should be visible from a distance of at least two nautical miles as well.

In addition to sidelights and sternlights, sailboats also require an all-round white light, commonly known as an anchor light. This light serves as both an anchoring indicator and a warning signal to other boats that your vessel isn’t under power and may be stationary. Typically mounted atop the mast or another elevated point on the sailboat, this white light must be visible from all directions within two nautical miles.

Now that we’ve covered the main types of sailboat navigation lights, let’s delve into their designs. While traditional incandescent bulbs were once widely used for their simplicity and affordability, LED technology has revolutionized marine lighting. LED navigation lights are highly energy-efficient and have a considerably longer lifespan compared to incandescent bulbs. Additionally, LEDs emit a bright and focused light, making your sailboat more visible to others even in adverse weather conditions.

Furthermore, many LED navigation lights come with built-in features that enhance safety and convenience. Some models have automatic sensors that adjust the brightness of the lights depending on the ambient lighting conditions. This means that if you’re sailing during twilight or dawn, when visibility is reduced, these lights will automatically become brighter for better detection by other vessels.

Moreover, some innovative designs include combination lights that incorporate both sidelights and sternlights in one compact unit. These multifunctional lights save space on your boat while still ensuring compliance with regulations. Additionally, there are folding or telescopic navigation lights available that can be easily stowed away when not in use, further optimizing your deck space.

In conclusion, choosing the right types and designs of sailboat navigation lights is crucial for safe night sailing and regulatory compliance. Sidelights, sternlights, and anchor lights are essential components of any sailboat’s lighting system. Consider opting for energy-efficient LED technology that offers enhanced visibility and longevity compared to traditional incandescent bulbs. Moreover, explore innovative designs such as combination lights or folding options to optimize space onboard your vessel. By equipping your sailboat with the right navigation lights, you can navigate confidently through the darkness while captivating other sailors with your illuminated elegance on the open sea!

The summer months of the year bring hours of sunshine, giving boaters plenty of time to explore during the day. When the sun sets, safety becomes a priority for anyone operating a boat in the dark. It’s crucial to know which boat lights must be on and how to stay visible and safe while sailing at night.

We’ll provide all the essential information you need to make sailing at night a safer and more enjoyable experience. You’ll get an overview of the different types of boat lights available and tips for staying safe and visible while sailing in the dark.

Safety Considerations

Safety should always be the top priority of any sailor, regardless of the time of day. When boating at night, you must know the rules and regulations in your designated area and familiarize yourself with the navigation equipment on most vessels. Understanding these regulations and investing in additional equipment can make a big difference in ensuring a safe voyage.

It is essential to understand the local laws and regulations regarding boating at night and what lighting you need for each vessel. Boat operators should also be aware of their speed limits, acceptable waterway passage areas, and any potentially hazardous areas they should avoid.

In addition to staying knowledgeable about local regulations, your navigation equipment should be up-to-date and functioning appropriately. Marine vessels typically come equipped with depth sounders and radar systems, but investing in additional accessories can further increase visibility during nighttime sailing. This equipment can include GPS chart plotters or portable AIS receivers, which can help navigate safer routes and alert boat operators of nearby vessels.

Necessary Lights for Boating at Night

Depending on illuminated waters after dark, boat light illumination is necessary for all recreational vessels. Boats must display three main types of lights, including bow, stern, and riding lights.

The bow light indicates to other boats where your vessel’s direction is facing, appearing as a green light on the starboard side and red on the port side when looking forward from the rear. It is important to note that this light should only be visible from directly ahead or nearly directly ahead of the vessel itself. It must have a wide enough angle range for optimal visibility while ensuring it is not too bright or blinding for other boats passing by.

The stern light works similarly to a bow light, except it shines from the back end of a vessel, making it easier for oncoming boats to identify your direction. Per maritime law, this light should also appear white but visible from behind only, ensuring no unnecessary glare toward other boats or obstructions ahead.

Riding lights, or masthead lights, provide additional visibility for your vessel. These lights indicate the vessel’s length according to measurements determined by maritime law enforcement officers. This type of light usually appears as white but occasionally has a blue tint depending on individual regulation standards in your area.

Understanding the Importance of Visibility

When selecting boat lights, it’s crucial to consider their wattage output or bulb type to ensure optimal visibility in dark environments.

Colored boat lights are often found on vessels and can come in white, blue, or red colors, each serving a specific purpose based on the laws at sea. White lights generally have a stronger output compared to other colors. Blue lights are more effective underwater, and red lights can mark specific areas within narrow channels, among other uses.

In addition to colored boat lights, reflective materials like tape can upgrade the common areas on ships, such as rails or posts. These materials help draw attention to the vessel’s proximity to other nearby ships and enhance safety.

Maintenance and Troubleshooting

Proper maintenance of boat light systems is crucial to keep operating costs low, especially when dealing with high-wattage fixtures commonly found in the marine environment. Regularly maintaining these systems throughout their lifespan is essential.

One critical maintenance aspect is storing boat lights properly during off-season storage periods. It is crucial to ensure that each unit remains dry. This storage is necessary to preserve their longevity and ensure their functionality when powered back on. Moisture buildup can lead to short circuits, malfunctions, and damage to the light’s components.

You should follow basic troubleshooting methods as part of routine maintenance. This maintenance includes cleaning off any corrosion and regularly checking bulb connections. These steps should become a natural course for anyone embarking on nighttime sailings or exploring uncharted territories.

Proper illumination is crucial for safe and legal boating at night. All boats need to have adequate lighting regardless of their size and capabilities. Following maritime laws and regulations related to navigational requirements and using the correct boat light format enhances safety for everyone on maritime travels. The mastery of navigation skills and adherence to these standards will continue to uphold the honor and legacy of future generations.

The Night Vision Techniques

Explore the techniques and tools for safely sailing under the stars with our comprehensive guide to night sailing, from preserving your night vision to navigating in the dark and following proper etiquette.

The Night Vision Techniques: A Comprehensive Guide to Night Sailing

Sailing under the stars can be a magical experience, but it also presents unique challenges and requires a different set of skills than daytime sailing. In this article, we’ll explore the essential techniques for maintaining your night vision, as well as tips for navigating and staying safe during your nocturnal adventures on the open sea.

Table of Contents

Understanding night vision, preserving your night vision, navigating at night, safety tips for night sailing, night sailing etiquette.

Before we dive into the techniques for maintaining your night vision, it’s important to understand how our eyes work in low-light conditions. Our eyes have two types of photoreceptor cells: rods and cones. Cones are responsible for color vision and function best in bright light, while rods are more sensitive to light and are responsible for our ability to see in low-light conditions.

In darkness, our eyes undergo a process called dark adaptation, which allows the rods to become more sensitive to light. This process can take anywhere from 20 to 45 minutes, depending on the individual and the level of darkness. Once our eyes have fully adapted, we can see much better in the dark, but it’s important to note that our night vision is still limited compared to our daytime vision.

Now that we understand the basics of night vision, let’s explore some techniques for preserving it while sailing at night:

1. Limit Exposure to Bright Light

The most important factor in maintaining your night vision is to limit your exposure to bright light. This includes both natural sources, such as the moon and stars, and artificial sources, such as cabin lights and electronic devices. To minimize exposure to bright light:

  • Keep cabin lights dimmed or turned off when not in use.
  • Use red or amber lights instead of white lights, as these colors are less disruptive to night vision.
  • Avoid looking directly at bright light sources, such as the moon or other boats’ lights.
  • Limit the use of electronic devices with bright screens, or adjust the brightness settings to minimize glare.

2. Allow Time for Dark Adaptation

As mentioned earlier, it takes time for our eyes to fully adapt to darkness. Before setting sail at night, spend some time in a dimly lit environment to allow your eyes to adjust. If you need to transition from a brightly lit area to a dark one, close your eyes for a few minutes to help speed up the adaptation process.

3. Use Peripheral Vision

Our peripheral vision is more sensitive to light than our central vision, making it more effective for detecting objects in low-light conditions. When scanning the horizon or searching for objects in the water, try looking slightly to the side of the object rather than directly at it. This will allow you to use your peripheral vision and increase your chances of spotting the object.

4. Keep One Eye Covered

If you need to briefly expose yourself to bright light, such as when checking a chart or using a flashlight, try covering one eye to preserve its night vision. This technique, known as the “pirate’s patch,” can help minimize the impact of bright light on your overall night vision.

Navigating at night presents its own set of challenges, but with the right techniques and tools, you can safely and confidently sail under the stars. Here are some tips for night navigation:

1. Familiarize Yourself with the Night Sky

Learning to recognize constellations and other celestial landmarks can be a valuable skill for night navigation. Familiarize yourself with the night sky and practice identifying key constellations, such as the North Star (Polaris), which can help you determine your latitude and direction.

2. Use Electronic Navigation Tools

While celestial navigation is a valuable skill, modern electronic navigation tools, such as GPS and chartplotters, can provide more accurate and reliable information. Make sure your navigation equipment is in good working order and that you’re familiar with its operation before setting sail at night.

3. Keep a Close Eye on the Weather

Weather conditions can change rapidly at sea, and poor visibility due to fog, rain, or clouds can make night navigation even more challenging. Keep a close eye on the weather forecast and be prepared to adjust your plans if necessary.

4. Maintain a Proper Lookout

Maintaining a proper lookout is essential for safe night sailing. In addition to scanning the horizon for other vessels and obstacles, pay close attention to the water’s surface for signs of changes in depth or the presence of debris. Remember to use your peripheral vision and avoid staring directly at bright light sources.

In addition to the navigation tips above, there are several safety precautions you should take when sailing at night:

1. Ensure Your Boat is Properly Lit

Make sure your boat’s navigation lights are functioning properly and are visible from all angles. This will help other vessels see you and avoid collisions.

2. Wear Reflective Clothing and Gear

Wearing reflective clothing and gear, such as life jackets and harnesses, can help make you more visible to other boaters and increase your safety on the water.

3. Keep a Sharp Ear

In addition to maintaining a proper lookout, use your sense of hearing to detect potential hazards. Listen for the sound of waves breaking on nearby shores, the hum of approaching engines, or the calls of other sailors.

4. Be Prepared for Emergencies

Before setting sail at night, make sure you have a well-stocked emergency kit on board, including flares, a VHF radio, and a flashlight with spare batteries. Familiarize yourself with emergency procedures and be prepared to act quickly in case of an emergency.

Finally, it’s important to be considerate of other sailors and follow proper etiquette when sailing at night:

  • Keep noise levels to a minimum, as sound travels farther over water at night.
  • Be mindful of your boat’s lights and avoid shining them directly at other vessels.
  • Give other boats plenty of space and avoid crowding popular anchorages or mooring areas.

Night sailing can be a thrilling and rewarding experience, but it requires a different set of skills and precautions than daytime sailing. By understanding the principles of night vision, practicing proper navigation techniques, and following safety guidelines, you can confidently set sail under the stars and enjoy the unique beauty and freedom of the open sea at night.

What are the proper sailboat lights at night?

As a sailor, it is essential to be aware of and adhere to proper sailboat lighting when navigating at night. These lights are necessary to ensure safety and avoid collisions with other vessels.

The International Regulations for Preventing Collisions at Sea (COLREGS) specifies lighting requirements for different types of boats. There are different lighting rules for vessels under power and those under sail. In this article, we’ll discuss the proper sailboat lights at night.

Sailboats are required to have three lights at a minimum: a masthead light, a red port light, and a green starboard light. The masthead light is white and is located at the top of the mast. This light should shine forward and aft and be visible from 2 nautical miles away. It is important to ensure that the masthead light is not obstructed by the sail or any other structure onboard.

The red port light is located on the left or port side of the boat and is visible from 1 nautical mile away. The green starboard light is on the right or starboard side and is also visible from 1 nautical mile away. These lights should shine out from the vessel and be visible from dead ahead to 112.5 degrees abaft the beam on either side.

In addition to these lights, sailboats that are underway may show an optional stern light. This light is placed at the stern of the vessel and is white. It should be visible from 2 nautical miles away and can be used to indicate that the sailboat is underway and not at anchor.

If a sailboat is not underway but still poses a potential hazard, it should display an anchor light. This is a white light that is visible from 2 nautical miles away and should be located near the top of the mast. This light indicates that the sailboat is anchored and should be avoided by other vessels.

It is important to note that the visibility of the lights depends on the weather and other conditions. In foggy or hazy conditions, the lights may not be visible from the specified distance. It is always a good idea to maintain a lookout and be aware of other vessels in the vicinity.

Proper sailboat lighting at night is critical to ensuring safety and avoiding collisions with other boats. It is essential to understand the required lighting regulations and to ensure that all lights are functioning correctly before heading out on the water. Remember to always maintain a lookout and be aware of other vessels around you. Happy sailing!

Night Sailing: A full guide to sailing in the dark

Pete Goss

  • September 23, 2022

Pete Goss provides an in depth guide to night sailing to help you get the most our of your boat when the sun sets

picture of a properly lit sailboat at night

Night sailing is bread and butter to an ocean sailor and often crucial to coastal passage making, be it to catch a tide, avoid bad weather or simply to eat up delivery miles in preservation of precious cruising time at the destination of choice. It is an essential skill and, like anything in life, it needs to be learned and then honed with training and experience.

The dark hours don’t need to feel threatening. Some of my most memorable moments at sea have been thanks to the magic of darkness as it blankets distant clutter to bring an intimacy with nature that eludes us under the harsh spotlight of the passing sun.

Sound seems to carry as the gentle chuckle of the bow forging its path carries to the cockpit. The hull’s motion is celebrated by the glow of a swirling phosphorescent wake. Waves seem to be accentuated and smells become evocative on the damp air. A moonless night sky descends to wrap us in a blanket of bright heavenly bodies, untarnished by light pollution. Conversely a full moon can cast its own spell – there is nothing like the magic of sailing down the reflective path of a moonbeam.

Perfect memory

Two weeks after rounding Cape Horn during the Vendée Globe I have a vivid memory of perfection. Earlier that day we had transitioned from a frustratingly fickle area to the blissfully consistent trade winds. The cloying cold became a memory as thermals were shed to welcome the refreshing joy of a deck shower. Flushed with the relief and optimism of surviving the Southern Ocean I had a rare four-hour sleep.

I awoke to find that darkness had ushered in a world of magic. Aqua Quorum quivered with joy as she surfed across building seas. The deck, speckled with spots of phosphorescence cast by surging water had come to life. Mesmerised, I sat on the companionway bubble, the only dry spot on board to be surrounded by a super pod of dolphin. Swirling streaks of phosphorescence around and under the boat marked their playful antics. It was a moment, too special to be caught on film, that has never left me.

Having become seduced by the intimate beauty of the night, it’s not unusual for me to gift the off-watch crew a full night’s sleep as I see it through to dawn. This comfort in the dark hours has taken time though. My first night sail was  sailing across the Channel  with my parents and I struggled as benign conditions became threatening with darkness.

My seasickness was accentuated and we seemed adrift in a void with no points of reference. Ships offered little sense of size, direction or proximity and rather than reassuring me, the few flashing lights on the coast seemed to taunt me. Even the colour-coded ropes lost their individuality as I fumbled about trying to make sense of this new world.

Having subsequently introduced many to night sailing I have realised that my reaction was common, so I thought I might share a few reflections on how to compensate to make night sailing safer and above all more enjoyable.

Night sailing spacial awareness

The visual horizon, reducing with darkness, needs to be replaced by the projection of spacial awareness. If you struggle with this break it down to focus on each of its components and layer by layer it will become a reliable comfort, effortlessly adjusting for tide, wind, waves and the quirks of your boat.

Couple this with a clear mental chart, created like a dot-to-dot picture linking available references from lighthouses to buoys, the looms of civilisation and even the passage of a ferry whose course offers a straight line reference between two ports.

The outcome can be remarkably accurate and I test mine by putting a circle of estimation on the chart before plotting our position. It won’t stand the test of measurement but it can offer a sense of reality which is both reassuring and can counter errors. A gut feeling that ‘that just doesn’t feel right’ can save lives.

Night sailing passage plan

Start with a detailed passage plan. Think about sight lines, wind and wave direction, where will lights pop up or sink below the horizon. Where will you be at dusk and dawn, will the weather bring rain, cloud cover or perhaps fog? What are areas of heightened risk – draw them on the chart, break them down for clarity. Pore over pilot books, talk to others to make your visual reference as detailed as possible.

Ideally take the crew ashore, draw breath and talk through the passage plan as you run your finger across the chart. You’re aiming to paint a lasting picture so keep repeating the passage of your finger as you add layer upon layer of information. Explain the limitations of darkness and the ship’s routines to mitigate them. Underline that casual daylight references such as wind and wave direction should be given more attention.

Setting a reliable passage plan is key when sailing at night. Photo: Richard Langdon

The heavenly bodies and even clouds can be used to avoid becoming compass blind. Steer with all your senses and be guided by periodic glances at the compass. The fact that these senses are inherent is illustrated by the steadying effect of asking a wildly erratic novice to close their eyes. It’s as if a primal gyro has been switched on as they steady up.

Give responsibility by asking one of the crew to take the forecast and relay it, another to go over your tidal calculations, another to organise the snacks and so on. Further this by having everyone take turns at filling in the hourly log and plotting the position. Breaking a passage into watches makes the handover of information essential.

Wake the oncoming watch with at least 15 minutes in hand. Welcome them with a hot cuppa and a general overview as they don their equipment. As they make their way on deck check safety gear and that hats and gloves are to hand. They must clip on before leaving the companionway and finding their feet. The off-going helm should stay by their replacement until dismissed. The new watch leader requires a formal handover of the boat set-up, visual references and chart updates.

Contrary to common misconception, navigation is often clearer during the dark hours due to the pinpoint accuracy and identification of navigational aids. What is clear at night can degenerate into a smudge with the coming of dawn. So make sure that the last fix of the night is exemplary for this could be the crucial fix from which all dead reckoning will follow. The flip side is that a city’s gaudy background can make identifying navigation lights very challenging.

Staying awake when sailing at night

Tiredness inhibits all senses, silently eroding safety and decision making. As darkness calls for as much alertness as you can give, so your body winds down, no matter how hard you fight it, to provide less and less attention as the night unfolds. A good watch system helps – two five-hour watches during the day to give a longer sleep backed up by short night watches. If a watch is really exhausted I will stand in as skipper to allow cat napping. Should broader exhaustion set in consider shortening watches, heaving to, anchoring up, or a revised passage plan.

Seldom does a landfall mesh with a watch system so consider extending the approach watch to ensure a well-rested watch for harbour approaches. If you are able to step outside the watch system, plan your sleep to be alert for decision points; headlands, tide changes, passing fronts or land fall. A clear understanding of when, where and why the skipper should be called will empower the crew to maintain alertness and resist the temptation to retreat into their hood.

Encourage movement, from press-ups to regular helm changes and scanning the horizon from the cap shrouds. Rotate the watch through plotting the hourly position, providing hot drinks, snacks and boiled sweets. Anything to maintain engagement and spacial awareness.

It might sound daft but be overt about no question being a silly question, particularly at night. The crew are your eyes and ears so encourage them to express any concern or intuition. Reward it by establishing the cause of their concern to provide a learning experience and safety check.

Night sailing watch routines

The most important entity on a boat is the crew, so spend your money on good clothing and personal equipment before being tempted by the latest gadget.

Watch for early signs of seasickness or hypothermia and take immediate action. Being on watch is a duty, so reduce talking to essential information; if feeling divorced from the elements drop your hoods and remove hats. Allocate quadrants of responsibility, scan the horizon by turning your head to improve hearing and other senses; open your mouth. Sporadically weave the boat to alter shadows, motion and noise. Walk up to the bow and stand there for longer than feels appropriate, as long as you’ve told someone you’re going up. You’ll be surprised how different things look, sound and feel up forward.

If it’s particularly dark or foggy I often turn off the navigation lights and run with the tricolour for short periods if motoring. This cuts glare and can be aided by posting a crew member on the bow if there is lots of shipping about. Periodically turn off the engine for a listening watch, even if sound isn’t necessarily directional in these conditions. If you have a plotter and radar below, put a crew member below and turn off the deck instruments.

Night vision

Contrary to common misconception it takes 20 minutes to gain your night vision. Red light is preferable but it still affects it.

Rather than red lights below I prefer red head torches to reduce light emission and ensure it is focussed. Remember red light can blank out colour definition on your chart.

A waning moon calls for greater light discipline as the nights get darker. Modern cockpits can suffer from screen blindness so don’t be afraid to put the cover on electronics and have a dedicated crew member looking as the others turn away.

Teach the crew to use their peripheral vision when scanning the horizon for it is much more sensitive. Once your periphery picks something up the eye will be able to focus on that to which it was blind. It takes practice to focus just above the horizon but is a revelation when you get the hang of it. If your direct sight still doesn’t pick it up use your binoculars.

There is nothing more damaging than a smoker flashing up their lighter. Ban smoking at crucial times, at others ask them to both mask their lighter and warn the crew before ignition. The smoker must face aft and draw behind their raised collar and hood. Recognise that life goes on below so have porthole curtains and drop in the washboards where appropriate.

Perspective

Darkness can bring a change to perspective so extra care needs to be taken when judging distance. I can’t offer any simple tips here apart from suggesting extra time spent on looking at landmarks and using your spacial awareness, binoculars, fixes and radar to correct any anomalies.

From hard experience I have found that on a very dark night a lone navigation buoy with nothing around it to offer perspective can jump from seemingly afar to right under your nose. During a training course for the British Steel Challenge I was off watch when we glanced off a hoofing great Trinity House navigational mark which I had laid down as a turning point. I didn’t hear the collision thanks to a lumpy night and being tired. It was dawn before a very sheepish mate woke me with the news.

In truth I thought it was a wind-up until I looked over the bow to be shocked by a large dent. I just couldn’t believe that four keen trainees under a Mate with thousands of miles including a circumnavigation could simply sail into such a big, well-lit buoy.

I interviewed them all separately and they all swore that they had watched the buoy from afar. All were confident of their position when it suddenly appeared under the bow with just enough time to throw the helm up.

I have since experimented under similar conditions to experience the same phenomena. On a very dark night I will always leave extra room and put a spotlight on the buoy from afar, ensuring that others have turned away with their eyes shut. It’s something that I have found to be remarkably consistent so beware.

Seasickness

Remember that seasickness is accentuated by darkness so be minded if you know someone is susceptible. Issue seasick tablets or even stand them out of the night watch, for an ill person is useless and needs looking after.

Darkness inhibits balance so be extra vigilant about clipping on and press home the ‘one hand for the boat and one for yourself’ mantra. This is particularly important as decks at night are often slippery with condensation.

Before any deck work have a team-talk to walk through the order of events and who will do what. A fun training exercise I used to great effect on the British Steel Challenge was to blindfold the crew on a quiet day to practise reefing and even putting the spinnaker up.

Equipment you need for sailing at night. Photo: Richard Langdon

Night sailing equipment

It’s important to have binoculars that have a wide lens to draw in as much light as possible. I have found that image stabilising seems to have a greater effect at night. Beyond that there is thermal imaging and IR scopes. My wife Tracey’s dream would be a FLIR Scope. I have yet to use the more exotic scopes on a boat but know from the military how remarkable they can be.

AIS is wonderful as it gives course, speed and risk of collision with vessels festooned with so many working lights they blank out their navigation lights. Radar is also an excellent aid to seeing beyond the darkness but once again it can inhibit night vision.

I like to provide the cockpit with a proper palm stopwatch with a neck lanyard for identifying lights. Wristwatches incapacitate both arms and are often lost in the confines of wet weather gear and thermals.

Don’t forget the ‘opposition’ are suffering from the same challenges so be ready to aid them by running a spotlight over the sails. Worst case, you might flash it directly at the ship’s bridge or ignite a white hand-held flare to avoid collision. Powerful LED torches are readily to hand in your pocket and have negated the constraints of an electric lead of older searchlights.

Use the steaming light for less invasive illumination, or better a dim, ideally red, torch. Photo: Richard Langdon

This is a difficult one that is best addressed by developing an intimate feel for your boat such that she can talk to you through feel alone.

Of course you should always sail within your ability and comfort zone but at the same time don’t be frightened of the dark. I personally wouldn’t change the way I sail between night and day. A boat should always be sailed well, for it not only reduces risk by making your destination earlier but also ensures the boat is happily responsive and able to talk to you. An underpowered hull will wallow to make deck work and moving about below riskier. It will also make extra leeway and tend to wander about the course to compromise navigation.

Get to know your boat, train for night manoeuvres by walking it through with the crew. Have some fun with blindfolds. I see no reason why the spinnaker should come down at night, for nothing that influences how the boat reacts is lost with light. A well sailed boat has a jaunty aura that lifts the crew’s enjoyment and alertness.

Should complex manoeuvres be required such as gybing the spinnaker I prefer to turn on the steaming light as opposed to the deck light which you can’t see beyond. Talk the manoeuvre through and slow it down by pausing between each step. Before you know it, night sailing will be like bread and butter. Always remember to give the horizon a good scan before turning on the steaming light.

You can use deck lights for sail trim and foredeck work, but it will completely blind you to anything outside the boat. Photo: Richard Langdon

Use your instruments of course but I find that a masthead windex is a great aid at night for it is clearer as it relates directly to the mast and sails. Trimming is generally easy at night if you have preserved your night vision. If needs be, a member of the crew can shine a weak torch at the tell tails while everyone else protects their night vision.

On racing boats I have seen a dim light shining up the headsail from the deck but this seems dangerous to me as it has to affect night vision. There are glow in the dark tell tails but I’ve found these wanting.

Don’t let instruments divorce you from your senses. It pays dividends to remove your hood and woolly hat to get a proper feel for the wind. The only ground I would give to sail setup at night would be to give extra weight to the forecast. If you know the wind will shift early on I might shelve the spinnaker and sacrifice a few miles by poling out the headsail. I might also delay shaking out a reef until the watch change. This would only be when cruising though.

Sailing solo at night is possible, but requires a higher degree of caution and less ambitious plans. Photo: Richard Langdon

Short handed sailing at night

I wouldn’t start with the premise that night sailing should be avoided, because it is quite safe and can offer the best of experiences. I would, however, make allowances if short handed or sailing with novice crew. If it feels like risk is elevated, make a proper risk assessment, which should include the possibility of breaking the trip into day sails where possible. I would also consider a delay when sailing two handed if both of you are ground down and at a low ebb.

If single handed I have a very loud alarm much like an egg timer and will judge my cockpit naps against the risk of collision. This can mean as little as five-minute naps for a ship can come over the horizon at a fair old clip so look at the shipping lanes, make a judgement. If five minutes feels risky then you just have to suck it up and stay awake with coffee, music and exercise, or whatever it takes, as long as it doesn’t wake the off watch.

If you are very tired when two handed, keep reducing the watches until they’re workable. I was once reduced to 20-minute watches. The golden rule is to get relief if you’ve stopped functioning properly.

Under pressure I personally don’t mind one of the on watch having a cockpit nap provided they are covered by their buddy. The reality is that two exhausted people are no more efficient than one that has had a nap as the boat works towards topping up a depleted sleep reserve through bad weather or some other perfectly acceptable reason. A lack of discipline or being hungover is not acceptable. The boat shouldn’t leave under these circumstances – that is what a conscientious skipper is for.

Fishing hazards at night

We’ve all been faced with an erratic fishing boat that is seemingly continually correcting any of your course changes back to a collision course. The reality is that they are focussed on fishing and are completely distracted from lookout duties.

This scenario is always compounded by a plethora of working lights which drown out their navigation lights. If there is a blessing it’s that their speed will be low thanks to the drag of their nets. This is where binoculars, radar and constant use of a hand bearing compass come into their own.

When passing in close proximity to a fishing boat I will always start the engine and leave it ticking over just in case drastic action is required. Although fishermen seldom respond to a VHF call, it’s worth a try. Other shipping are much better at responding and helpful, particularly when crossing a busy shipping lane. AIS is hugely helpful here: not only can they see you but you can identify a ship’s name for your VHF call.

  • How to sail at night

Captains are often asked if it's possible to sail at night. In the vast majority of cases, the answer is yes, unless you are just starting out. You just need to know the specifics of night sailing — the rules of boat lighting, beacon signals, have navigation and nautical charts handy, and most importantly, follow basic safety rules on board. So, do you know what night sailing entails?

You can't do it without the correct lights

While on land, lights are primarily there to help us see, at sea it's the other way around. All boats must be properly lit for other vessels to see. And, a boat doesn't work like a car either, where we shine our headlights on the road ahead to see what's in front of us. At sea we rely on navigation, nautical charts, lighthouses and the captain's knowledge.

Basic boat lights include running lights, steaming lights and anchor lights. There are clearly defined and standardized rules for lighting a ship  under sail at night . So the question of how to light a yacht at night has a very simple answer. Running lights, or side lights, show other vessels where your port and starboard sides are, with red indicating port and green starboard, and you must also have a white stern light on.

Lighting the yacht at night is very important because, unlike during the day, the helmsman cannot judge the distance and direction  of other boats by sight. Running lights make the position and direction of the surrounding vessels visible, as well as their approximate distance, and helps to avoid possible collisions. Radar is also highly practical in this respect, as it shows the size and distance of the vessel.

However, when sailing there can be situations where the sails need to be lowered, and with that, the lighting also needs to be changed. If travelling under motor power , a steaming light  (masthead light)  must be turned on , which shines at the same angle as the side lights. When a sailboat is not under sail, it has to abide by the rules set out for power boats by COLREG (The International Rules for Preventing Collisions at Sea).

Lighting regulations when at anchor are again different. When at anchor at sea , only the anchor light should be on . According to the regulations this could be either a 360-degree white light atop the mast, or a light suspended from the boom, above the foredeck or on a furled genoa. If the boat is moored in port, the light is not normally used.

Navigation, GPS and maps

Nowadays, GPS and navigation aids integrated into the boat or that work as mobile apps are commonly used to determine the position of the boat. Modern technology is very accurate and reliable, but it is still worth understanding, reading and checking your position on  paper nautical charts . After all, almost any skipper will tell you that their GPS or navigation system has at some point told them they were on land, even when tens or hundreds of metres from shore.

Thanks to nautical charts, you will not only know of possible danger spots, but also lighthouses , enabling you to easily and accurately determine your position with the help of a compass. Each lighthouse is different, being lit and flashing in a unique way. A nautical chart will tell you how to identify a lighthouse by the number of flashes, their frequency and the colour of the light. To determine your exact position, you’ll then need two lighthouses in sight that serve as reference points for each other.

YACHTING.COM TIP: Lighthouses are not only practical, but they are often buildings with impressive architecture that are well worth stopping off at. Take a look at  15 lighthouses you must visit .

Safety is paramount when sailing at night

Even during the day, there are clear rules regarding the movement of the crew on board. Basically, the crew should not stand unless they are engaged in manoeuvres. In all other cases, they should be sitting on benches, at the side of the boat when heeling, or in the cabin. Apart from the fact that a standing crew member could obstruct the helmsman's view, it also poses a greater risk of falling overboard . If you're interested in getting to know this subject in more detail, check out our article Sailing Etiquette A to Z .

At night, the rules are even stricter to ensure the crew remain as safe as possible and avoid damaging the yacht. If a crew member is on deck at night while sailing, they should wear a lifejacket  and ideally be attached to the boat with a lifebelt or harness.

Except for really experienced seafarers, the rule of thumb is that there should be at least  two people on board when sailing at night. And the captain should schedule shifts so that there are always two  rested crew members on board. After all, you need to be doubly vigilant when sailing at night, and staying awake all night is certainly not conducive to alertness — especially when manoeuvring  or entering port. For the same reasons alcohol is prohibited when night sailing. While during the day, crew members other than the helmsman can toast Neptune or have one glass of wine or beer, drinking alcohol is not permitted during a voyage at night. By all means celebrate a successful journey upon arrival in port at a local tavern, but it definitely pays to keep a clear head at sea.

Specifics of night sailing and boat handling

Steering and controlling the boat  is not particularly different during the day and at night. There are just a few nuances to make sailing that bit smoother. If you're on a vessel you know well, that’s one thing, but if you're on a charter boat , it's worth marking the sheets and other lines so that you know your way around in the dark.

Sailing at night, it is also important to assess  the weather conditions well. What you would normally do during the day can be significantly more challenging at night and requires a more careful assessment of weather conditions and weather patterns. It is always better to choose smaller sails and if you have even the slightest doubt about anything, postpone the trip. 

When  entering a harbour  or sailing close to shore, be doubly cautious. There are several risk factors. During the day, the surrounding boats, the rocks and the potential hazards on the surface and below are visible. At night you have to rely on navigation, charts and lighting. When entering the harbour, charts and GPS can provide you many clues but lights can cause issues. For example, you might get dazzled by the light from the shore, the anchor lights of other boats are easily confused with the lights on land, and, last but not least, you may encounter poorly lit fishing boats. However, if you keep in mind all of these potential risks, you will arrive safely in the harbour.

The magic of night sailing

When compared to sailing during the day, night sailing places more demands on the captain's experience and knowledge of sailing regulations. But it is also a truly romantic experience. Millions of stars glistening in the night sky and the waves sparkling in the moonlight. If you're lucky, sailing out of the mist from land on a clear night with a near full moon, it will seem almost like daylight.

If you're serious about sailing and steering your boat, there are other benefits to night sailing. Navigating at night sharpens the senses and enhances the sailing experience as well as your experience of the sea itself. It truly gives a whole new meaning to sailing. But if all you want is to just enjoy yourself, night sailing is one of the most romantic experiences you can have. Check out our article on how to enjoy romance on board a yacht charter .

Great article! Boat lights are the means of communication between sailing vessels. These lights are also a tool to let my presence known even from a distance.

Sailing at night: tactics and tips

By Author Fiona McGlynn

Posted on Last updated: December 2, 2021

As an early-to-bed person, I find a night passage offers special and sublime opportunities for stargazing, precious alone time, and quiet contemplation. However, I’ve also found myself wet, cold, and not-so-quietly contemplating the lights of a ship bearing down on us. Does that tanker see us? Fortunately, after 3,000 nautical miles of trial and error while sailing from Canada to Mexico, my partner, Robin, and I have learned a few tricks that make night passages more comfortable and serene.

sailing at night

Feed the crew

Good hot food makes all the difference in keeping energy (and spirits) up on a night passage, especially when very little cooking is involved.

Minimize galley time – It takes three days for most sailors to get their sea legs, so we like to have no- to low-effort meals and snacks planned for those first days at sea. Less time spent in the galley also means we have more time for the boat, rest, and sleeping. To minimize galley time, we prepare all our food for the first 24 hours at sea ahead of time. One of our go-to evening meals is soup, made in advance and kept warm in a thermos on deck. After the first 24 hours, quick-to-make meals (canned soup, beans on toast, curry in a bag) are a good bet.

Splurge on fun treats – We stock a “sin bin” with trail mix, chips, and chocolate and also prepare some of our favorite nibbles (muffins, scones, cinnamon buns). Milk chocolate is good for a jolt of energy, but doesn’t keep us up past our watches.

Stay hydrated

Water is very important for keeping the mind alert on night watch. In fact, dehydration is often mistaken for fatigue.

Keep a water bottle on deck – One of our friends has a rule that anyone who yawns on the boat must take a drink of water. Every member of the crew should keep a water bottle on deck when on watch. As well as making water accessible, this is a good way to monitor intake.

Serve warm drinks – One of our favorite hot drinks is Chai tea, kept in a thermos in the cockpit. We make it by adding an inch of fresh ginger to three cups of water, bringing it to a boil, and then adding cardamom, honey, and black pepper to taste. The spices and honey give us a boost without the diuretic and stimulating effects of caffeine. Cider (the soft kind!), tea, and hot chocolate are great too.

Sleep, glorious sleep

Sleep can feel scarce when sailing overnight, but we take steps to manage it.

Sleep before leaving – First, we make sure we’re well rested before we leave. We never start a passage with a sleep deficit.

A workable watch schedule – Sailors use many different watch schedules and tailor them to the number of crew on board. To find out what works best for us, we started with shorter watches (of perhaps 1 to 2 hours) and increased the length over time. We usually sail with just the two of us (plus autopilot) and find 3-hour watches work well, but on many occasions we’ve gone to shorter watches because one of us was not able to stay alert for the full 3 hours. If you’re hand steering, definitely err on the side of shorter watches. And when you feel like you can’t keep your eyes open, it is always better to wake your partner than risk snoozing at the wheel.

Avoid alcohol and stimulants – One of the principal ways we improve the quantity and quality of our sleep on board is to avoid alcohol, caffeine, and other stimulating drugs. The half-life of caffeine is 4 to 6 hours in humans, so the chances are, someone who drinks a cup of tea at the beginning of a 3-hour watch will still be feeling the effects at the end of it. When this happens, it’s then tempting to use alcohol or sleeping pills to get to sleep. Alcohol has been proven to reduce the quality of sleep. The result is waking up feeling more tired and feeling the need for more coffee, and thus the vicious loop repeats.

Try light sleep aids – One sleep aid to consider using is the seasickness medication Gravol. Someone already taking Gravol for seasickness might consider timing the dose at one-half hour before the end of a night watch. This gives the Gravol time to kick in, aiding sleep at just the right time. By the time the off-watch is over, the Gravol has been partially processed and, you hope, the effect is less drowsiness and no seasickness. For those not taking Gravol, a cup of chamomile or valerian tea half an hour before the end of their watch will help sleep come more quickly.

Get comfy – We made sure we had a safe and comfortable sea berth by setting up a snug leecloth on a berth close to the boat’s center of gravity, where the the off-watch sleeper would feel the least motion (see “ Make your own Leecloth ,” January 2017). Earplugs and an eye mask help reduce stimuli to further aid sleep.

Staying awake

Staying awake on night watch can be difficult, but we engage in a number of activities to help us keep our eyes open.

Stay occupied – If we don’t keep ourselves lightly occupied on night watch, we find it difficult to stay awake, so we create watch routines that keep us focused and alert. Filling out our ship’s log is one such task. I’ve learned that one of the most effective things I can do to avoid dropping off is to keep my brain engaged in some light listening (podcasts, music, audiobooks) through a single earbud. This keeps me awake while I scan the horizon and listen for any changes in the boat or environment. If you’re in need of something to listen to, check out the salty audiobooks at Audioseastories.com , GoodOld Boat’s online store.

Keep moving – When I get overly drowsy, I stand up and dance in the cockpit. Though I might look ridiculous, it gets the blood moving and keeps me sharp a bit longer. If dancing is not your thing, stretching or jogging in place also works.

Set alarms – When I find I’m feeling a bit droopy-eyed, I set a wristwatch alarm to go off every 10 minutes, just to catch me in case I do accidentally doze off. Of course, if I do fall asleep, I realize as soon as I wake that my best option is to wake someone else to take the watch.

What to wear

It’s hard for me to appreciate the beautiful starlit sky when I have wet feet. I prefer to stay warm and dry.

Rubber boots and foulies –My favorite piece of gear is a 1980s yellow Mustang survival suit I picked up in a thrift store. While higher-tech options are available, I love my survival suit because it’s like wearing a giant sleeping bag on deck. I have foulies (foul weather gear), too, which are great for more active sailing, but when I’m hunkered down in the cockpit all night, my chief concern is staying warm. The other great thing about the survival suit is that I stay warm even if it gets wet. I once took a wave down the back of my survival suit and, though wet, I was warm again in less than a minute.

Buy some bum padding – Deck cushions can get in the way while sailing, so we usually stow them. I sometimes wear a pair of padded cycling shorts under my foulies to provide some insulation from the hard, cold cockpit seats.

No cotton garments! – Or atleast don’t wear them on chilly nights. When the least bit damp, cotton can get cold and clammy. We choose wool, polyester, and other technical fabrics for layering as they don’t hold moisture against the skin.

Clip in – A tether and harness are musts for enjoyment and comfort while sailing at night. We much prefer the view of the ocean from the boat than the boat from the ocean. Plus, the off-watch rests easier knowing the on-watch is tethered safely to the boat.

Warding off the green

Perhaps the number-one thing we do to ensure our comfort while afloat is avoid getting seasick. Many remedies are available, including Gravol, Dramamine, Transderm-V patch, ginger, and acupressure wrist bands. We try any drug or remedy on dry land before taking it while sailing, just in case we experience a negative side effect. One seasickness medication on the market made my vision blurry. Once you’ve found something that works for you, start taking it at least 12 hours before setting sail so it has time to properly kick in. We are often helped by spending a couple of nights in a slightly rolly anchorage before heading out.

Bits and bytes –  Two pieces of technology are a boon for any sailor venturing out under the cover of darkness.

Autopilot – An autopilot helps minimize crew fatigue. Handsteering becomes far more challenging and tiring at night, when limited visibility can affect orientation. An autopilot allows for longer and more restful watches.

AIS – If you have it, AIS is a terrific additional source of information at night. It’s a great comfort to know the course and speed of the twinkly bright lights bearing down on us in the darkness. We can easily hail the vessel in question, by its name, if that’s listed on the AIS target, or by private hailing its MMSI number using the DSC-enabled VHF. Once in contact, we ask whether they can see our boat and whether they plan to alter course in the near future. We like to set our AIS alarm so we don’t miss any vessels that will approach within 2 nautical miles.

Passage planning

The decisions we make before leaving the dock undoubtedly have the greatest impact on the comfort of our night sail.

Choosing a weather window – Poor weather and sea conditions become considerably less fun in the dark, so we plan around adverse weather. We avoid night passages when the swell period (in seconds) and height (in feet) are close in number. For example, a 7-foot swell with a 12-second period will be a lot more comfortable than a 7-foot swell with a 7-second period.

Sail in your comfort zone – If you’re comfortable sailing in up to 20 knots of wind, limit overnight passages to wind conditions of 15 knots or less. Conditions can feel a lot bigger at night and so we do not push ourselves past our comfort limits, and we sleep better as a result.

Use the full moon – We’re much more comfortable on night passages when the moon is full or nearly full. All that light makes it easier to spot obstacles and we’re psychologically more at ease when we are able to see our surroundings.

Leave and arrive in daylight – The approaches to many ocean ports are littered with crab traps, long-lines,dead-heads, kelp, and other debris. We prefer to heave-to for a couple of hours rather than risk fouling our propeller attempting an entrance in the dead of night.

Passages of manageable length – If you’re new to sailing at night, it’s a good idea to slowly build up to longer and longer sails. As you start planning multi-night voyages, think about the best way to break the passages down. Many solo sailors we know choose to never sail more than one night at a time so they can pull in and have rest days after each night passage. Personally, we like trips that are three days or longer, because we find it takes that long to adjust our sleeping patterns. Experiment with different passage lengths until you find a style that leaves you feeling rested.

Strategies for sailing at night

Whether we feel safe and comfortable at night has a lot to do with how we set our sails. Proper planning makes the difference between restful slumber and a sleepless night for the whole crew.

Prepare before dark – We complete the necessary tasks —like setting the sails and organizing the cockpit — in daylight so the crew on night watch has fewer things to focus on.

Brighten up – To avoid things that go bump in the night, invest in some good lighting. We were sailing down the Mexican coast and noticed a large trawler tailing us. We tried to radio the trawler only to realize that it was our buddy-boater, Jim, who had cunningly invested in high-wattage lights that made his 35-foot sloop appear to be a much larger vessel. We’ve found red lights and headlamps help us to get around the boat without impairing our night vision.

Set sails for comfort – We don’t sleep well with a slamming mainsail on a rolling boat. We play with different sail plans and courses to make our boat as comfortable and quiet as possible. We use a boom preventer , for example, to reduce the motion and noise of the mainsail. When sailing dead downwind makes things very rolly, we’ll head up a bit for a smoother ride. Our VMG (velocity made good) might suffer, but that’s preferable to having a tired crew. When we’re dealing with light and variable wind at night, we find it well worth the extra fuel cost to run the engine, so the person below can get some sleep.

Slow down at night – We usually take in a reef before dark. We might lose some speed, but our boat is a lot more manageable if the wind picks up later — and we don’t have to put in that reef at night.

Schedule maneuvers – When possible, we plan our maneuvers, such as tacking and gybing, so we can do them before it gets dark. We schedule them for watch changes to minimize the number of times we need to wake someone mid-sleep for help on deck.

By adopting these strategies, we’ve begun to really enjoy sailing at night. In fact, we’re finding now that we even prefer it, because it means we don’t lose a day of shore time upon arrival in a new port. With the right preparation, you can make nights at sea not only pleasant, but also special and beautiful times. So make things comfortable for yourself, try some tips to see what works best for you, and then sit back and enjoy the stars.

While I also do just about everything mentioned in the article, as a singlehander, there are no crew changes, so making sure hot drinks (I like decaf Irish Breakfast tea with a couple of cinnamon sticks thrown in) and light snacks are within reach of the cockpit are very important. I also added glow in the dark draft strips to my sails and I've added glow in the dark stickers to the stanchion bases. I love night sailing—it's almost a religious experience being out there, sailing in calm seas under a full moon and a sea of stars above. One word of warning though, if you're new to astronomy, don't be surprised if that North Star you've been following turns out to be the 9:40 flight from Chicago...just saying.

Good article.

The very best, THE VERY BEST, anti seasick remedy for me has been Motion Ease, sold at West Marine and Walmart. After many remedies were tried and were unsuccessful, Motion Ease was the first remedy that I found successful. We were in 38+knots of wind between Nassau and Eleuthra and the cook brought sandwich "fixins" into the cockpit. I was already seasick and could only manage a slice of bread and cheese wadded up in my fist. My wife remembered I had bought Motion Ease several years before but I had never tried it. She went below and brought up the tiny bottle. I rubbed one drop behind each ear and within 15 minutes I was eating a Dagwood sandwich! The remedy is applied to the skin area behind each ear and works even if you are already seasick. About $5 at Walmart, maybe more at West Marine.

Friday 30th of June 2017

Thanks for the recommendation Jim! I've never tried Motion Ease but will definitely give it a go now.

Seven Tips For Night Sailing

7 Tips for Night Sailing

By: Pat Reynolds Cruising Tips , Learn To Sail , Safety

Now that we’re into the summer months, lots of you might want to stretch your skill set and do a bit of night sailing. It’s a bit of a different animal so we’ve cobbled together seven things to keep in mind as you head off into the wild black yonder.

  • Dress accordingly It may be obvious for some, but don’t forget the big ball of yellow heat will be replaced by a cold little white ball that will not help the warmth cause at all. Your ability to enjoy the pleasure that a gorgeous night on the water can provide is directly proportionate to you being dressed for the environment. Don layers, with a spray jacket on top and life should be good.
  • Carry a decent searchlight Night boating involves becoming accustomed to the available light and acclimating to it. It’s actually one of the cool things to experience during a sail in the dark, so constantly shining a spotlight like you were hand-holding your car’s headlights is not where it’s at. That said, there are instances where having a high-powered light on board can make things considerably safer. Coming into a harbor, verifying a navigational aid or identifying something foreign in the water are all common situations that benefit from a good light.
  • Stand a watch Of course someone should always be keeping an astute lookout whenever the boat is underway, but this is hyper-important during the restricted visibility that night sailing involves. If you’re lucky enough to have a bright full moon than things are a bit easier but short of that, it’s dark out there folks! Someone needs to keep a mandated watch. By the way, if that person is you, be prepared to have one of the most quality “alone-times” you’ve ever had. People are known to find the meanings of their lives on night watches. You might well return from your nice sail and promptly quit your job, dump that angry spouse and finally get in shape!
  • Don’t push Many old salts attach a different attitude and mentality for night sails. During the day the fun might be to vigilantly trim and adjust, catch lifts, shift weight and monitor that knot-meter for that rewarding uptick – 3/10s of a knot – Yes! “ Herman are you secretly racing that little boy in the sabot? ” “ No, of course not. ” But Herman is racing that little boy in the sabot! Anyway, at night it’s good to downshift and run the boat at a lower percentage. Enjoy the serenity this time of day has to offer and understand that downsizing the operation a little will make for a safer and more fulfilling experience.
  • Make sure Waypoints are Clear & Safe Most sailors rely on electronic aids to see them around the waterways and at night they become even more important. They can also, in certain situations, make things less safe. A few years ago, the famous Newport to Ensenada race reported their first deadly accident when a group of sailors ran into a small island off the coast of San Diego. After an investigation, it was determined that the sailors, in all likelihood, didn’t account for the land-mass (island) when they entered in their waypoints. They might have been sleeping or just not paying attention when their cruising boat tragically ran up on the rocks. This would never have happened during the day, but sailing at night brings with it these kinds of considerations.
  • Know the Light Patterns Fortunately charts and boats are all set up for sailing at night so it’s absolutely essential that the skipper and at least some of the crew know what the language of lights is saying out there. Boats are equipped with lights situated in such a way that other boats can tell what’s going on and charts are filled with light-related information that will clue mariners in on where they are. It can be confusing to look into a harbor located outside of a city and try to understand what is going on. “ Why is that harbor entrance light switching from green to red like that? Oh, that’s Washington blvd… ” Know what to look for and how the lights behave and the confusion will be greatly reduced.
  • Wear a PFD We understand that not everyone wears their pfd for whatever reason – it’s not comfortable, it’s filthy from lying on the floor for the past month, it sucks away at your already limited sex appeal – we get it. We don’t agree with the decision, but okay. For night boating, swallow your reasoning and put that thing on. Things can get slick on the boat at night and God forbid you end up in the drink, that little pea head of yours is very hard to see in the night. If you’re floating around for a while screaming “over here!” things are vastly better. Attach a battery powered personal beacon/light to it while you’re at it. Follow our advice and should you end up overboard you’ll be back in the boat in no time!

Night Sailing: Seven Main Tips to be Safe and Happy

Night Sailing love sailing

If you plan to do a bit of night sailing , there are several things that you need to consider. Here are several tips to keep in mind if you’re going to be sailing at night .

Personal Flotation Device

We understand that life jackets might not be comfortable, but when you’re sailing at night it’s a very good idea to have your personal flotation device on. Some personal flotation devices can have a beacon or light attached to them which makes it easier to find you in the water if you happen to fall overboard. by using a personal flotation device, you simply improve your safety when on the water at night time.

Clear and Safe Waypoints

You should make good use of your electronic sailing aids to ensure boating safety at night. You should also make sure that the waypoints you have entered your navigational aid are correct so you don’t have any mistakes while sailing at night. Make note of your surroundings such as islands and other obstacles to ensure that each one of your waypoints from point A to B is going to be safe for you to sail through.

Know Light Patterns

When you sail at night you may encounter other boats, so it’s critical that you understand the lights on other boats. This will let you understand what is going on out on the water. When you understand what the various lights mean and what they are doing, this will help keep you safe and reduce confusion.

Dress for Weather

At night you’re naturally not going to have the warmth of the sun so you should dress according to the weather. On the water at night time, it can become quite chilly even if the daytime temperatures have been hot. If you want to enjoy your time on the water, make sure you have proper attire for nighttime sailing.

Have a Watch

While you want to enjoy sailing at night you should also have someone as a lookout and a watch. There’s going to be restricted visibility so even though moonlight might give you some light, you should still have somebody watching things as you sail. It might be boring being on a watch, but it’s essential to ensure safety. If you boating alone, you’re going to be the person on the watch so you must not only steer your boat but be cautious of where you’re going.

No Need to Rush

At night time it’s a good idea to run your boat a little slower. At night time you want things to be safer and you can have a better experience if you’re not sailing as fast as you might say out during the day. You won’t have as much reaction time at night so it’s a good idea to keep things slow and easy during a nighttime sail.

Good Searchlight

Your eyes will become accustomed to sailing in the darkness, but you still want to have a good Searchlight in case of emergencies. You may need the flashlight when you want to verify a navigational aid, come into the harbor to park your boat, or try to identify something in the water that might be foreign such as a log or other small obstacle that might be dangerous to your boat. You should have a good searchlight for all situations because you never know what you might encounter in the water at night time.

Sailing, yachts, adventure and sailing around the world, colregs, lights & sailing at night.

Despite learning all my lights and being a nerd with the Coastguard Boating Education flash cards, when you are at sea at night it is really hard to decipher navigation lights on other boats.

I think the main difficulty I have is knowing how close you are to the other boat. We don’t have radar on board, so only have our eyes to judge. Is it a huge ship far away or is it a small ship really close? Who knows! Either way, I have no idea how close we got to the fishing boat we passed on the way back from the Sounds in January.

Here is everything I need to refresh for the Ocean Yachtmaster course I am currently doing:

I can highly recommend this online course if you are wanting to brush up on your knowledge: https://sistershiptraining.com

COLREGS – are the international collision regulations at sea and they are designed to ensure that boats know who gives way to who.

These rules apply to everyone on the water – boats and even sea planes!

One of the most important rules in the COLREGs is that all vessels shall maintain a proper lookout at all times. This means that you need to use not just your eyes but your ears as well – and if you have other means such as AIS and Radar – then great use those as well. If boats don’t obey this rule then all the other rules are pretty much useless. You wouldn’t drive your car along the street without looking right?!

Another important rule is that boats need to operate at a safe speed so that you can take proper action to avoid a collision – this means you have to take in to account the visibility, traffic density, your vessels manoeuvrability and distance required to stop, the state of the weather and sea conditions, and the depth of the water.

So if you are keeping a good lookout and notice another boat heading in your direction, you need to next determine if a risk of collision exists. A good way of doing this is lining up the other boat with a fixture on your own vessel – like a stanchion for example. If the boat stays in line with that (the bearing remains the same) then there is a risk of a collision.

So the next step is to figure out what the other vessel is up to and then make a decision on who is going to give way to whom.

There are a few different ways of doing this – some will be obvious, and others require a bit more consideration. But you will need to take some action and it should be made in ample time and with consideration of good seamanship.

The give way boat can take action by slowing down, stopping or changing course and doing so in a manner that the other boat can see that you have done this and they can stand on.

So how do you identify what the other boat is up to and decide if you are going to give way or not? Lets start with some easy ones:

In Narrow Channels

Boats should keep to the right hand side of the channel – and pass port side to port side.

If you are a small vessel – yacht or powerboat, you should give away to all vessels who can only navigate in this channel.

So here in Lyttelton for example – we can sail all over the place, but the ships can only navigate down one strip of the harbour which is dredged. We must give way to them because they are “constrained by their draft”.

If you get in their way – they will give you five short blasts on their horn which basically means “Get out of my way!!!!”. ( Trust me this is not fun …)

People who are under way tend to give way to boats which are anchored.  (see this is all common sense people!!)

If you are at anchor – you must show an all round white light. Or during the day – a black ball suspended at the bow. If the vessel is over 50m, then they show two all round white lights – one at the front and one at the stern. If the vessel is over 100m in length then they must also show other lights to illuminate the decks.

Boats less than 7m and not going faster than 7 kts

If you are a fast manoeuvrable boat, and not restricted in the way  – then you should give way to smaller boats

At night they also only need to show an all round white light, or if you are in a dinghy you can use a torch. Basically just try not to run these slow little guys over, and likewise, if you are small and slow you might not want to be navigating through busy shipping lanes at night if people are unlikely to be able to see you.  (just sayin’!!)

Boats Navigating at Night – Port, Starboard & Stern Lights

These are shown when a vessel is under way (i.e. not at anchor) and help you to identify which direction a vessel is travelling. If you can see both the red and green at the same time, then it means they are heading straight for you!

If you can only see a white light then it could either be a vessel at anchor, a slow vessel travelling at less than 7kts or a vessel travelling away from you – its stern light.

navigation-lights

Yachts or if you are from America – Sailing Boats

Yachts under 20m, when sailing must show a port, starboard and stern light and they can be combined in a tri-coloured mast head light.

If the yacht is motoring then it also needs to show a seperate stern light and a masthead white light.

If the motor is on – then you are considered to be a power driven vessel and those rules apply – see below.

Yachts  – when they are sailing, have right of way over power boats – including ships when you are out at sea. When yachts are on starboard tack, they have right of way over yachts on port tack. And leeward boats have right of way over the windward boat when they are both on the same tack. (I won’t go in to heaps of detail on this but its worth doing some more research on this if you are planning on sailing in the vicinity of any other yachts)

Power Boats

Powerboats over 12 metres in length must show the port and starboard lights, a stern light and a mast head light – which should be 1 metre higher than the sidelights.

If the powerboat is less than 12 metres then it can combine its stern and masthead light in to one all round white light.

Power boats give way to other boats approaching on their right hand side.

Note that in the picture above, say the white boat doesn’t look like it is going to give way and the stand on vessel decides to take action themselves – they should turn to starboard – if they went to port and the other guy decided to finally show that he was giving way then you could cause another crash.

Towing Light

If you are towing another vessel, you display a yellow light instead of a stern light. This means that you have right of way over most boats. When you are towing you a restricted in your ability to manoeuvre, but you still give way to anyone who is anchored, aground, and constrained by their draft.

Under Way & Making Way

Under way, means that a vessel is not anchored, docked or secured. Making way means that it is actually moving through the water/over the ground.

Vessels Not Under Command

These are vessels which are unable to manoeuvre and keep out of the way of anyone else. Perhaps they have lost all power to their engines or broken their rudder or something like that.

They show two in line all round red lights or two red balls during the day. If they are actually making way through the water then they must show port, starboard and stern lights too.

I remember this by thinking of two red stop lights – i.e “Stop stop these guys are not under command”

Now this is where it gets a bit more complicated…!

545_NAVIGATION_LIGHTS_international_rules_002

Vessels Over 50m in length

Must show two white mast head lights (facing forward) and one white stern light. The front light should be lower than the main masthead light. They also show port & starboard lights.

Vessels Aground

Obviously if a vessel is aground then it isn’t going to be able to give way to anyone else! These guys show two all round red lights over one white.

Vessels Restricted in their Ability to Manoeuvre

These vessels are restricted in their ability to move because of the nature of the work they are undertaking – so they might be dredging, towing, launching aircraft or something like that.

They show three lights all in line red, white red or a ball, diamond, ball during the day.

If they are fishing or dredging, and this might be a hazard to other ships, then they will display two green lights or two diamonds on the safe side, and two red lights or two red balls on the side with the obstruction.

Basically everyone except vessels not under command or aground, must give way.

Not sure how I remember this one but I seem to be able to!

Vessels Constrained by their Draught

These are big ships who are restricted to the channel, and can not deviate or they will run aground. They give way to vessels not under command and vessels restricted in their ability to maneuver, but everyone else gives way to them.

They show three all round red lights in a line or a cylinder during the day.

Pilot Vessel

Shows a white over red light.

I remember this one with the rhyme “White over red, the pilot is out of bed”

Vessel Fishing

A vessel fishing usually shows a red over white light or two triangles facing point to point (wine glass shape)

I remember this one with the rhyme “Red over white, fishing at night”

However they can also show a green over white light if they are trawling. If they have a single triangle out to one side, or a single all round white light, then this indicates that there is fishing gear extending out that side for 150m.

Vessels Towing

If the length of tow is less than 200m the towing vessel shows two all round white lights or a diamond shape and a yellow stern light. The vessel being towed shows their normal lights.

If the length of tow exceeds 200m, then they display three all round white lights.

Other Rules of the Road

In Harbours

Smaller boats should give way to any ships over 50m in length.

In Narrow Channels or meeting head on.

Vessels should stick to the starboard side of the channel, alter course to starboard and pass port to port.

When Overtaking

The overtaking vessel gives way to the stand on vessel being overtaken. The stand on vessel can pass either side, but should make their intentions clear. The stand on vessel should maintain their course, and avoid speeding up to race the passing vessel or swerving over in front of them to stop them from being able to overtake… 😉

You know you are the overtaking vessel if you can see the other vessel’s stern light. If you can’t see that then you are a crossing vessel and the ‘give way to your right’ rule applies.

If you are overtaking and want to let the other vessel know what you are doing – you sound two long blasts followed by two short blasts. This means I am going to overtake you on your port side.

The stand-on boat being overtaken and sound a reply with one long one short one long and one short and moves over to the right.

Sailing Vessels

Power boats should give way to yachts.

We have got heaps of crazy yacht rules, but basically those on port tack, give way to those on starboard, and windward boat gives way to the leward boat. Alternatively in a race whoever yells the loudest and has the biggest balls usually gets their own way.

Power Vessels Crossing

You must give way to a vessel on your starboard/right hand side. If the vessel to your left does not appear to be giving way to you, then you should turn to starboard, because if you turn to port (or towards them) and they finally figure out what they are doing and try to pass astern, then you could crash.

Honestly, you would not believe the number of people who have boats and have absolutely NO IDEA what any of these rules are. Arraggh!

Confused? Here is a bit of a summary. Anything listed above your kind of vessel you give way to – anything below gives way to you.

  • Vessels Not Under Command. (So thats someone who has lost their engine or steering and can’t control where they are going. You’ll also want to give way to all vessels who are at anchor and aground…)
  • Vessels Restricted in their Ability to Manoeuvre RAM (Towing someone, big ships in narrow channels, laying submarine cables, etc)
  • Vessels Constrained by their Draft (big boats restricted to the shipping channel)
  • Vessels engaged in fishing (no that does not include you if you’ve got your rod over the side – but big fishing boats with gear extended)
  • Sailing Vessels – while actually sailing – give way to boats on starboard tack and boats on the same tack to leeward.
  • Power Driven Vessels – anything motoring along gives way to anything approaching on their right hand side

The day signal to show you are on anchor is one we found not many knew – they’d ask us if we kept our lunch in the ball! 🙂

Like Liked by 1 person

Would be a handy place to keep it! Is it actually a ball or a flat circular shape? Did you hoist it up the genoa halyard or where?

Great post! Lot of lighting stuff i didn’t know!! Very informative. Thank you 🙂

I also heard stories of people calling “Starbard” and the response is “14 tonne!!!” (Or more) …… 😉

Very cool post, thank you for sharing. It is fun comparing these regs to the regs here in the US. For the most part they are the same however here each State has slightly different rules regarding small boats.

Good to know!

My understanding of colregs was that no vessel ever has “right of way” vessels are either “stand on” or give way. The stand on vessel does not have a right of way but an obligation to hold course and speed to enable the give way vessel to manoeuvre that craft to avoid collision.

Further should the stand on vessel become concerned about collision they are obliged to take avoiding clear manoeuvres at an appropriate time or not a last second manoeuvring risk laden turn off speed change.

Long story short “I had right of way” won’t wash in maritime court.

Yes good point. Everyone has a responsibility to avoid a collision 🙂

Sailing at Night: Top Tips

30th jan 2018 by samantha wilson.

Rightboat logo

If you’ve never sailed at night then you’re really missing out on one of the most magical and soulful sailing boat experiences possible . The stillness of a star-lit sea on a cloudless night can be a contemplative adventure that distills the very essence of pure sailing.

However, it does raise challenges. How well do you know your yacht’s layout in the dark? How do you anticipate the squalls and gusts if you can’t see them?

In this guide, we’ll look at a few hints and tips to help make your night sailing experience safe and secure .

Night Vision  while Sailing

  • If you’ve been wearing sunglasses all day, allow up to 40 minutes for your eyes to adjust to the dark . Night vision relies on rod cells in the eyes. They can take 20-40 minutes to adapt to darkness.
  • Ensure your navigation screens are dimmed and turn off any unnecessary light-emitting electronics .
  • Use a red bulb in your flashlight if possible. If you’re using a white bulb then avoid shining the light directly at the rig, as the reflected light will destroy your night vision.

Night Sailing with Red Bulb

Food and Clothing while Sailing at Night

  • Don’t forget that no matter where you are sailing, it always gets cooler at night to ensure that you wear adequate warm and dry clothing.
  • Store hot drinks and food within easy reach of the cockpit.

Night Sailing with Food and Clothing

Safety Equipment while Sailing at Night

  • Ensure all crew members wear a lifejacket and harness whenever they are on deck at night. Make sure everyone is aware of the clip-on points and jackstays. Even if you are sleeping in the cockpit, don’t go forward without someone else clipped on and awake in the cockpit.
  • Review your man overboard procedures and ensure the light is attached to the horseshoe/DAN buoy. Check before you commence the voyage.
  • Any crew member on watch should be equipped with a red bulb flashlight, a knife, and a personal EPIRB/AIS locator.
  • Ensure that all gear is carefully stowed away. Set up lee cloths and check that all seacocks that need to be closed are closed.
  • Test any communication equipment before leaving.

Night Sailing with Safety Equipments

Night Watch while Sailing at Night

  • Set up a clear watch schedule to ensure all crew members have adequate rest and breaks. If there are only three people on board, a three hours on-six off watch system will ensure all crew has adequate rest time whereas a four-man crew could operate on two hours on four hours off system. Brief your crew thoroughly to ensure that everyone knows and understands the watch system and what your expectations are.
  • Make all crew members aware that they could be called onto the deck at anytime.
  • Never post an inexperienced crew member on watch alone. Pair them up with a more experienced member of the crew.
  • The retiring crew should give the new watch a briefing on sea and weather conditions, hazards or traffic in the area, and any relevant information as to the state of the boat. Remember the crew member taking over the watch may have only just woken up. Ensure they are awake enough to carry out the watch- your life is in their hands!
  • Rest. Don’t be tempted to stay up all night star-gazing on deck. Even if you don’t sleep, rest in your berth to ensure you are fresh and awake for when it’s your turn on watch. Set an alarm for about 15 minutes before your watch period is due to begin and get some food and drink.
  • Be considerate to your off-watch crew. Tether deck hooks and rattling pans in the galley; sound travels farther on a still night. If you’re running a generator, consider timing it to be split over two shorter watches rather than over one long watch. Alternatively, charge batteries in the afternoon and watch your power consumption so you don’t need to use the generator at night.
  • Don’t get lost in a book whilst on watch. Keep your head on a swivel and simply enjoy the experience of steering the boat and the sights and sounds of the night. Scan the horizon every 10 to 20 minutes. Check the radar and AIS and make proper log entries.

Safe Night Sailing Watch

Seamanship at Night

  • It’s a good idea to make your first night sail in familiar waters with a full moon to aid visibility.
  • Under Rule 25 of the International Regulations for Preventing Collisions at Sea , a sailing vessel must exhibit both red and green sidelights and a white sternlight. The craft under 20 metres can combine the prescribed lights with a tricolour lantern near the top of the mast.
  • Rule 23 states that a sailing vessel under power must exhibit sidelights, a sternlight, and a white masthead/steaming light forward. Make sure your ensign isn’t draped over the stern light. Test all lights before leaving and make sure you carry spares for all lights.
  • Identify any navigation marks that have light characteristics using your charts. For quick reference, make a note on your passage plan the sequence of expected lights. Work out a clear bearing from the navigation lights and make a note on your passage plan to avoid hazards. Plot a series of GPS waypoints and use the “navigate” function to follow a reference guideline.
  • Although it is easier to see other vessels at night, it is also easy to confuse the distances involved. Assess a vessel’s intentions by keeping a good watch and adjust your path accordingly. Keep a close eye on your radar and AIS but don’t rely on them solely. Fishing boats tend to have unpredictable movements and lights so be vigilant when on watch.
  • Don’t run at 100% . Most skippers operate at 80% capability at night. This will help minimise any disruptions and will ensure a comfortable ride.
  • Base any sail adjustments to be made by each watch on your crew’s experience.

Chris Tibbs on how to prepare for and enjoy offshore night watches

picture of a properly lit sailboat at night

With a full moon and following wind, night sailing can be one of the great pleasures to be had when passagemaking; but on a dark night in a gale it can be very stressful and leave you longing for dawn.

Whether you are crossing the Channel or crossing an ocean, sailing in the dark is something that everyone experiences at some stage in their sailing career and with some simple preparations you can make it easier and safer.

Have you ever been asked by a non-sailor: “What do you do out on the ocean at night?” It often comes as a surprise to find that sailing has always been a 24-hour pastime.

Traditionally, passages were made at night and planned so that landfall was at dawn to assist with identifying the lights and confirming the yacht’s position. Then the skipper could enter port safely during daylight.

With GPS we now rather underestimate the usefulness of lights for position fixing and, as more yachts are fitted with AIS, crossing shipping lanes has become less difficult now that you are not solely reliant on identifying each ship’s navigation lights.

Of course, not all vessels have AIS!

How to prepare for long passages

Generally night sailing falls into one of two categories: the first is a one-off night sail, such as the start of a summer cruise to get the boat to your cruising ground, or perhaps a RORC or JOG cross-Channel race. The second is a long passage where there will be a number of days between the start and finish with consecutive night sails.

For me there should be little difference when setting up the boat although there will be a difference in watchkeeping.

Whether cruising or racing, the crew spending consecutive nights at sea requires a more rigid watch system – covering the full 24 hours – than the one-night crew. But the principles of watch-keeping do also apply to single nights at sea.

One of my pet hates used to be the Friday night cross-Channel races. Crews would arrive all enthusiastic after a hard week at work, but by 0200 tiredness had set in and we would see ourselves slowly working our way to the back of the fleet with only one or two awake enough to be competitive.

Most boats are logical in their layout and it is always a pleasure when a new but experienced crew comes on board as they will rarely need telling twice which rope is which.

Yes it is good to label clutches but soon after joining everyone should know by feel and position which rope is which.

Close your eyes and feel – size becomes very apparent and the covers will feel different. Hold the spinnaker halyard in one hand and the topping lift in the other; feel the different sizes and textures.

It is always good to keep the same ropes in the same position so at night in the dark, when the label is obscured anyway, it is easy to pick up the right one.

Humans are not particularly good at seeing at night and it takes a long time to get full night vision.

The eyes are incredible complex and there are three phases in adapting to the dark.

Initially our pupils dilate to allow as much light in as possible; this may take from a few seconds to a minute to happen.

The next phase takes place in the cone cells of the eye. In the absence of light we get chemical changes in the cell and it can take ten minutes for the cone cells to adapt to the dark.

Lastly we have rod cells which are responsible for black and white vision and these contain rhodopsin which is reactivated in the absence of light. This will take several hours to fully adapt to the dark.

Although we are all different, as a rough guide it takes about ten minutes to get most of our night vision, which gets slowly better over the following few hours. This can be put back to zero very quickly by the use of bright lights.

How to use lights on board at night

All crew members should have a flashlight and it’s worth keeping a powerful spotlight on deck for rig checks and emergencies.

When sail trimming try and use as weak a flashlight as possible and also warn the helmsman and lookouts before using it.

picture of a properly lit sailboat at night

We have had great success in painting the lenses of flashlights with red nail varnish: the red light is much kinder on the eyes and nail varnish is more readily available than red flashlights.

Red lights are also crucial below. Some yachts will have split lights with red to be used at night. In the past, I have used stick-on red film from a photographic shop.

Generally we cover half of the lights red when cruising, but for long offshore passages we will cover all the lights with red film to avoid the wrong switch being used.

It would be nice to have two complete circuits to turn off the white lights completely, however ten minutes with a pair of scissors and all lights are covered.

Head torches leave both hands free, but I actually hate them on deck when sailing. If spoken to it is the natural reaction to turn and look at the person speaking, instantly ruining their night vision. Some head torches will have red bulbs but any bulb shining straight into your eye is damaging for your night vision.

Use light sparingly as the less you use, the less you tend to need. With the latest instruments and multifunction displays you can control the brightness of the image: keeping it to a minimum helps night vision and also consumes less power.

I am told that in training, some Mini Transat and Figaro sailors will practice sailing blindfold.

Night sailing tips for cruisers

I have been involved with the ARC for many years and it seems that most crews will routinely drop spinnakers and reduce sail for the night. All very prudent but nights are long in the tropics – approaching 12 hours of darkness.

I am not one for fixed rules, so I would rather see a boat set up for simple sail handling and allow conditions to dictate the sail plan. This also depends on the number of crew on board and the watch-keeping regime.

It makes sense to mark halyards and control ropes. I like to sew in a whipping of a contrasting colour onto the line marking the correct position just out of the clutch. This can be felt as well as seen and is particularly useful when reefing.

I also like to mark halyards at the maximum hoist to avoid anyone getting too enthusiastic and winding the splice or knot into the sheave. This is something racing boats have done for years and for cruisers would be useful for both day and night sailing.

Luminous draft stripes can be added to sails to help with sail shape and small amounts of reflective tape can also be stuck around the boat to help see and identify equipment.

On my boat the wheel is marked with a turk’s head knot to feel the centre point, to which we have also added some reflective tape to make it visible in low light.

If you make sail changing and trimming simple you can usually do it with just the ambient light and a small flashlight. The decklight knocks out any visibility forward. A tricolour light should light up the windex and if conditions are marginal, a steaming light can be used to check spinnaker trim, although any lights forward spoil night vision and, of course, a steaming light indicates to others that you are motoring not sailing.

When planning a voyage, make life easier and safer by maximising your moonlight hours: sailing under a full moon and clear sky is as easy as sailing during the day.

Crew preparation

Sailing is no fun when tired and hungry. There seems to be a tendency on cruising yachts to run short-handed with single-person watches. Of course, single-handed sailors circle the globe in ever faster yachts, but the average cruising yacht is not really very well set up for single-handed sailing.

picture of a properly lit sailboat at night

Hot drinks and snacks at night are essential.

The typical cruising yacht has a number of roles to perform, so the ideal deck layout in terms of sailing efficiency will be compromised by the requirements of the cabin space below.

This tends to encourage slow sailing: if it is hard to single-handedly reduce sail, it makes sense to automatically reef at night so you do not have to call anyone to help.

Two or three hours is long enough to be up on your own and with shorter watch times, there is the opportunity to change sail during a change of watch when there are two people on deck.

When my wife and I are double-handed passagemaking, we stick to three-hour watches, as this is as long as I can keep concentration. But it is tiring. For ocean crossings we tend to have an extra person to help.

Night raids and the importance of the midnight snack

When racing you have to push 24 hours a day to be competitive, although you can be a bit more conservative at night to help preserve the boat and crew.

When I skippered Concert in the BT Global Challenge, we would occasionally do a ‘night raid’. This involved handing out a few extra treats for dinner then, putting the best drivers on the helm, we would really push through the hours of darkness. This usually paid off with a few miles gained.

I would be happy to cross an ocean on freeze-dried food but I think I am in a minority! Food and drink is important for fuel and also for enjoyment.

Food at night is particularly important for energy and well-being. Sealed personal drink flasks stay hot for a couple of hours, the biggest danger being burning your mouth in the first hour. Snacks are also good on night watches: our bodies are used to sleeping at night and a snack helps to keep us going.

One trick that I like is a Cup-a-Soup in a wide-mouthed flask with a few teaspoons of couscous added. Put the lid on and leave it five minutes and you have a tasty and filling savoury snack!

How to be a watchkeeper

Watchkeepers should not take the responsibility lightly. You need an experienced watchkeeper crossing the Channel due to the level of shipping and navigation required on the passage. Further offshore a less experienced watchkeeper has more time to call the skipper.

Why longer passages are easier

Everyone on board has to get enough sleep. It may be possible, physically, to go 24 hours without sleep, but decision-making suffers and it is easy to make mistakes.

I prefer, if possible, to have at least two people on a watch, this avoids having to call extra crew for small sail changes or manoeuvres. It does also mean that when you are off watch, your sleep is not disturbed. With two on watch, three or four-hour watches pass quickly, split between steering, lookout, and navigation.

Racing is a bit different as there is generally a bigger crew. I am not a fan of everyone on the rail all night, and rotating the crew so everyone gets some sleep is important.

For longer races like the Fastnet I would have a rigid watch system so everyone gets some good sleep. If anything goes wrong then it always seems to happen at about 0400 when people are at their lowest ebb.

I would also get into the watch system early, probably before Portland, to get into a rhythm. Our bodies are very complex and need time to adjust; a short passage of two or three nights can be more tiring than a transatlantic.

Personally I find it takes about three days to get settled. I then get one really good deep sleep and I am fine for the rest of the voyage. I tend to find short passages – anything less than three days – more tiring, which is why I prefer a bigger crew for sailing a few hundred miles than I do for sailing longer passages.

7 Top tips for Safety at  night

• Prepare your boat: mark all halyards and brief crew on cockpit layout • Be patient with night vision: it takes three hours to fully adapt and moments to ruin • Red lights: either use red see-through film, red light bulbs or even nail polish • Get into watches early on the voyage: the body needs time to adjust to a new rhythm • Good food is especially important at night when the body is conditioned to be sleeping • Think safety and preparation: don’t run a one-person watch if the boat’s not easy to sail solo • Avoid getting overtired: concentration and decision making is essential at sea

Top tips for sailing at night

When most boats have moored up for the night clive loughlin ventures out into a different world.

Top tips for sailing at night

There is something rather magical about sailing at night, and I love it.

In many ways very little changes – the chart plotter, depth sounder, log, AIS and radar still work just as they do in daytime, and yet somehow everything is different.

Although you can sail at night with your eyes glued to an electronic screen, it is much more fun (and safer) to supplement technology with traditional techniques, and I hope the following will help you brave the dark.

Not to be undertaken lightly

Probably the single most significant safety measure is to make sure that your eyes have adapted to night vision before you set off (see box).

Most saloon and cabin lights are far too bright to be left on at night, and yet it is important to be able to pop down below without stumbling around. I like to use a bicycle rear light, or other torch switched to red mode, and reflecting off the saloon coachroof to provide a dim bordello-like atmosphere.

Switch on compass and instrument backlights and dim chart plotter displays to their lowest setting. They may look too dim at first but they will soon seem brighter as your night vision kicks in.

  Dressing for the occasion

It gets cold at night so you must wrap up warm, and a woolly hat and gloves are essential.

Over the years I have spent a fortune on ‘sailing’ gloves and been disappointed. I now use industrial gloves designed for people working in refrigerated warehouses. These give me the dexterity I need, and are warm and very low cost.

A man overboard is really really bad news in daylight, but in the dark it is a literal nightmare. So always wear a lifejacket and clip on.

The eyes have it

The sensitivity of our eyes increases the longer they are in the dark and it typically takes 30-45 minutes for maximum sensitivity to be acquired, and the improvement is dramatic. Unfortunately it can be lost in a few seconds of exposure to bright lights.

Eyes have cones that are used for colour vision in daylight, and more sensitive rods that come into their own at night. The rods are not sensitive to red light and this means that if you switch to red illumination (or red ‘Steampunk’ goggles) your eyes can continue to adapt while you move around the boat.

Each eye adapts separately and pirates used to wear an eye patch so that one eye was always adapted to darkness. This enabled them to move easily between the bright Caribbean sunlight and the vestigial gloom below decks.

The bad news for those of pensionable age is that your eyes will only be about a third as sensitive to low light as in your youth. Binoculars will boost illumination by about fifty times and go a long way to redressing the balance; but it still pays to have your youngest crew on lookout.

Paper charts still reign supreme in a number of areas and one of these is the display of lights, and in particular the sectored lights that are so crucial for our safe arrival into harbour.

I simply cannot get on with having a red light at the chart table. The same goes for chart plotter ‘night modes’ where the colour palette is changed to something gothic. I much prefer a very dim white light so I can view charts as nature intended.

Guide to Sailing at Night

A cunning plan

A pilotage plan on a whiteboard in the cockpit is handy for the navigator and crew to refer to and saves countless trips to the chart table. I like to use a book light clipped to the whiteboard. A standard book light is far too bright, but can be made useable with a few layers of primary red nail varnish or a wrap or two of masking tape.

A pilotage plan wants to be the simplest you can come up with that will safely do the job; and with a few backup strategies in case the main one doesn’t work out for any reason.

Don’t assume that a navigation mark is lit, as most, including some cardinal marks, are not.

Yellow buoys (seasonal special marks) may not be there at all, but you are generally pretty safe to assume that port and starboard lateral marks, cardinals, sectored lights and lighthouses are all present and correct.

As with daytime pilotage, you cannot beat a forward or back transit for keeping you on track.

Around harbours most lit navigational buoys will have a visible range of 2-5nm, while main channel markers and important cardinals will have a 5-10nm range and lighthouses can be visible at 25nm.

Cautious sail plan

Moving around on deck should be avoided whenever possible and so it makes sense to only have out sails that are well within the conditions at the time.

In busy areas I also like to have quite a bit of the headsail rolled away as this improves visibility looking forward.

Light spotting

Towards shore the horizon will likely be a confusion of lights and it can be very difficult to spot the one you are after. One trick is to work out the bearing that the light is meant to be on and get the boat heading in that direction. Then the crew can restrict their searching to just 10 degrees either side of the bow, and this narrows the field considerably.

The biggest danger comes from deciding that a light is the one you are looking for simply because you want it to be. The green light you are actually looking for may be as yet too dim to be seen, but a bright alternative on ‘more or less’ the correct bearing must surely be it?

Judging distance can be very tricky as well. Is that a bright light a long way off or a dim one much closer?

Lights can also come up on you in a bit of a rush. On numerous occasions I have been heading for a mark for half-an-hour or so with it seemingly never getting any closer and then suddenly it is 50m off the bow and evasive action is called for. Ships are even worse.

Guide to Sailing at Night

Look behind you

My crew is often surprised by just how few lights are provided in anchorages and rivers. If there is nothing ahead to guide you then full use must be made of back bearings.

For example, the very popular anchorage in Newtown River on the Isle of Wight has no lights at all within, but it does have the smallest lit west cardinal known to man just a few cables out from the entrance.

Fishing pots have been in the news a lot recently with the Cruising Association campaigning for them to be made easier to spot. Whatever happens in the future it is likely that they will always be difficult to see at night, and the crew need to be on their guard and looking ahead on both sides of the hull, especially if under engine.

Silhouettes

Although shore lights can be a distraction for most nocturnal navigation, if you happen to be looking for an unlit buoy or mark (a popular task for Yachtmaster candidates), plan the approach so that the mark is between you and the lights ashore.

A good torch

For close-quarters maneuvering you simply cannot beat having a trusty crew on the foredeck armed with a powerful narrow-beamed torch. They need to be careful never to shine the torch on the deck or headsail, as this will blind everyone on board, but they can quickly earn their rum ration by scanning the torch around to highlight any obstacles that threaten the boat’s safe passage.

One of my first outings as an instructor included a night time pilotage up the river Beaulieu in January. This is a sparsely lit passage at the best of times, but on this occasion there was no Moon and the few navigation lights had been removed for winter maintenance. My fledgling career was saved by the rapid deployment of a ridiculously powerful torch that was able to pick out the red and green reflective marks on the piles in sufficient time before we ploughed into them.

I would be remiss if I did not caution against head torches. They are fine for the person wearing them but are a menace to everyone else.

Navigating At Night

An article from Captain Kent Dresser

Navigating at night can be an enjoyable part of your recreational boating experience. It can also be a very dangerous part if not approached properly.

Night navigation requires skill and concentration and should not be taken lightly. Many things change on the water after daylight. While on your boat at night, your depth perception decreases and distances and sizes of shores and navigational aids can look different. Waves become harder to see and judge and reflections in your boat's windshield can be confusing.

Your night vision can be drastically reduced by bridge and city lights as well as lighted buoys that are close aboard. All of these factors should be taken into consideration when navigating your vessel at night.

Before navigating at night for the first time, it is a good idea to take someone with you that has night navigation experience. You should always ensure that all of your electronics are working properly and invest in a high quality spotlight. Remember that landmarks and navigational aids are going to look different at night and you will need your spotlight to double check buoy colors and numbers while underway. Always make sure that all of your running lights are operating and are not blocked from another mariner's view by flags or other obstructions attached to your vessel.

When using your spotlight, you should take whatever steps you can to prevent from shining your spotlight into the wheelhouse of other boats. You can easily ruin another boater's night vision with your spotlight. Be prepared to look away from other vessel's spotlights should that skipper shine his light into your wheelhouse. Only turn your spotlight on for the amount of time you need it to light what you are looking at. Never leave your spotlight on continuously while underway as it can distract boaters that are a fair distance away. If you feel the necessity to leave your spotlight on at all times, you may want to reconsider taking your boat out at night.

When using your electronics, it is a good idea to turn down the brilliancy of their backlights. Your eyes will not have to adjust as drastically between looking at the waters ahead of you and looking at your electronics if you keep them as dim as possible. Also, remember, that after a few hours of looking at a radar or GPS screen, you can very easily become fatigued and develop a headache. Don't hesitate to take a break and let someone else steer occasionally to help cut down on fatigue.

Unless you are involved in an emergency, there is no reason to navigate at full speed in the darkness. Don't hesitate to back off the throttles and give yourself more time to react at night. Keep a very sharp lookout for lobster pots and unlit buoys as well. Both of these objects can appear much smaller at night and can be much easier to hit.

When navigating in the vicinity of other boats in the dark, remember that it is possible that the other boater does not see, or is confused by, your running lights. Watch nearby boats closely to ensure that they are not on a collision course with you. If a nearby boat does look to be on a collision course, make a dramatic course change if possible and try to make yourself more visible. Turning your spotlight on without shining it directly on a nearby boater more often than not attracts just enough attention to alert the other boater to your presence. Remember, try not to destroy the other boater's night vision.

Use extra diligence in ensuring that your passengers and crew do not fall overboard at night. Locating a person in the water at night is very difficult and your chances of recovering that person are very slim. Keep less experienced passengers seated and don't let anyone wander onto open decks alone or unnecessarily. Always wear your life jackets and insist that everyone on-board your boat does as well. Imagine throwing a coconut overboard while cruising at night, then turning around and trying to find the coconut. How well you can see that coconut is a good representation of how well you would see a person floating with their head just above water.

All of these factors should be kept in mind when approaching night navigation. Remember that night navigation requires considerable focus and concentration and should not be taken lightly. Learning to navigate your boat safely at night can add a whole world of enjoyment to your boating career. Failure to learn proper night navigation techniques, however, can quickly land you in the middle of a very bad situation.
