How To Jibe Like the Pros

• By Gary Jobson
• December 1, 2023

The most important word when jibing is control. The helmsperson, sail trimmers and entire crew need to be diligent. The mainsail boom will swing across the boat with great force if important steps are not taken. There are many cases of serious injuries to unsuspecting crew who were hit in the head by the boom, or who tumbled overboard with the rapid change of course.

By contrast, completing a successful jibe provides great satisfaction when executed with precision.  

The best time to jibe is when a boat is sailing at full speed. The force of the apparent wind on a sail is less when sailing swiftly, which makes steering easy. The reason to jibe is to head on a more direct course toward a desired destination, or to take advantage of a shift in wind.

In advance of a jibe, one person, who is usually steering, should hail the crew about the intention to jibe. This is the proper time to assign specific duties to each crewmember so that everyone is clear about their role during the jibe.  

Once in proper position, the crew should stand by for a countdown to the maneuver. The helmsperson should turn the boat slowly, leaving no one caught off guard. Verbally state the new course, and visually look at any references, such as objects on shore or other boats, to know where the boat will be heading after the jibe.   

The sail trimmer should trim in the sails as the boat makes the turn. This is particularly important with the mainsail. Keep the sail under control so that the boom doesn’t swing wildly across the deck. Trim in the mainsail as the boat turns, and let it out rapidly as the sails fill on the new course. Just before the mainsail swings over, the helmsperson should hail, “Heads!” This will alert the crew to keep their heads low. 

In heavy wind, the ­helmsperson can execute an S-course jibe. Just as the mainsail is swinging across, the helmsperson turns the boat briefly in the direction the mainsail is heading. This action depowers the wind’s force on the mainsail. Once the boat is on the new course, the mainsail can be eased out to its most efficient position. The course that is steered is the shape of the letter S.

In winds less than 10 knots, most boats will jibe through 70 to 90 degrees. In stronger winds, a boat will jibe through 60 degrees or less. In a good blow, I suggest easing off the boom vang and securing the traveler in one place before jibing. This will depower the pressure on the sails and the rig.   

The jibing process is more complicated when a ­spinnaker is being flown. If the ­spinnaker is symmetrical with a ­spinnaker pole, then the helmsperson should be particularly careful when steering. The foredeck crew needs to exert downward and forward pressure on the spinnaker pole to keep it under control as it is being rehooked to the mast.   

Avoid rapid turns. Give your crew adequate time to shift the spinnaker pole. The sail trimmer in the cockpit is positioned to keep the sail full. Good teamwork is the key.

In recent years, the asymmetrical spinnaker has become a popular sail. I find that inside jibes are generally more efficient. This is when the sail passes inside the fore-triangle. The sail trimmer eases out the old sheet so that there is plenty of line to trim on the new jibe. The turn of the boat is usually a little faster than when jibing with a symmetrical sail, but it should not be any faster than the sail trimmer can move the sail from one side of the boat to the other. Continue changing course smoothly and constantly when jibing with an asymmetrical spinnaker. A pause can cause the sail to wrap.   

I find it interesting how many modern yachts resort to roller furling systems to handle forward sails. This applies to headsails and staysails. The sail is simply rolled up before jibing and rolled back out after the jibing maneuver is complete.  

I suppose I could add a technique or two for schooners and other multimast boats.  For example, schooners set a gollywobbler between the masts. On some schooners, it is best to have two of these quadrilateral sails ready to set on either jibe. When it is time to change course and jibe, take down one and hoist up the other on the new jibe. You just need two sails. But that is a story for another day. 

5 keys to safe jibing

• Give the crew ample warning that a jibe is about to take place.
• Assign each crewmember a specific job.
• Keep the mainsail under control; don’t let the boom fly across the boat.
• Look for a reference point on land to head for on the new course.
• Do not turn the boat too quickly.

How To Tack and Jibe A Sailboat – A Beginners Guide

Harnessing the power of the wind is a wonderful feeling, but it does mean one thing: You’ll have to obey the rules of the wind. When your destination is near where the wind is coming from, you can’t just sail directly there. Learning how to tack and jibe is one of the first steps you’ll need to take if you want to start sailing .

While tacking and jibing themselves are simple concepts, there are some important things you need to think about. A good tack means knowing why, when and how you’ll be tacking. Read our simple steps and learn how to tack and jibe.

WHAT IS TACKING AND JIBING?

Tacking means turning the boat through the eye of the wind (the direction the wind is coming from) and catching it on the other side. Since the sails catch the wind from the head, tacking offers a lot of control and can be performed with ease.

Jibing (or gybing) means you are turning the boat downwind from one side of dead downwind (the direction the wind is going) to the other.

The wind is coming from behind the sails and boom, so it can catch the mainsail and hurl it from one side of the boat to the other. This means it must be performed carefully and is fundamentally less controlled than tacking.

Unlike going into the wind, you can actually sail dead downwind but only with a specific sail plan. Often, your sails will require you to jibe downwind. Knowing your points of sail and what they mean is a great way to start learning how to sail.

WHY DO YOU NEED TO TACK?

Since you can’t sail directly into the wind, you must tack up into it if that’s your destination.

Sailing requires catching the wind in the sails to power them up and move forward. That means that the sails must be at an angle to the wind. The angle depends on the direction you want to travel in, relative to the wind.

WHY DO YOU NEED TO JIBE?

You can only sail directly downwind with a spinnaker or twin headsails. Other sails like cruising chutes allow you to sail almost dead downwind. However, many sailors don’t want to buy or change extra sails. So, they stick with a jib/genoa and a mainsail for all wind directions.

Jibing is usually performed when you want to sail dead downwind or near enough. You can jibe downwind so that you are zigzagging down along the wind’s path just like when you tack you’ll be zigzagging up towards the wind.

WHEN TO TACK

Knowing exactly when to tack will depend on where you’re going and the type of sailing you’re doing. In a race, tacking too early or too late could lose you the medals!

Generally speaking, you want to stay as close to the direct path to your destination as possible. This means that you’d tack fairly regularly.

However, you also need to remember that tacking makes you lose speed for a minute or two. So, you don’t want to tack all the time. In a narrow channel when you must go upwind, you’ll be short-tacking. This is where you tack very regularly. Possibly even every couple of minutes!

WHEN TO JIBE

As jibing is less controlled, some sailors avoid it as much as possible. If you’re not in a rush, you can technically tack instead and turn the boat in an almost full circle. If you’re in very strong winds, it can be preferable to tack. However, a controlled jibe is always possible.

Similar with tacking, you’ll need to jibe when you’ve gone as far as you want off your direct line and plan to take another zigzag back over it.

HOW TO TACK

Tacking is simple although the technicalities will vary from boat to boat. For a cruising yacht, the helmsman will pull in the mainsheet in as tight as it can be without causing the boat speed to drop off.

The helmsman will then shout, “ready about!” or a previously agreed upon phrase. This alerts the crew that the boat is going to tack.

Note that many modern yachts have a self-tacking foresail. This means that nothing needs to be done with it as it will simply tack itself when the boat tacks.

The crew member controlling the foresail will wait until the helmsman has turned the boat into the wind and out the other side before easing the foresail that will already be trying to tack itself. The same crew member or another one will pull in on the foresail’s opposite line as the first line is completely released.

Once the boat is pointing in its new direction, the helmsman will ease out the mainsheet and the crew will winch in the foresail. The faster you tack, the less speed you will lose!

HOW TO JIBE

Jibing is less forgiving than tacking. While tacking does not require the mainsheet to be in tight, jibing does. The first step is for the helmsman to pull in the mainsheet so it is as tight as possible. This prevents the wind from whipping it from one side to the other.

The second step is for the crew on the foresail to sheet in. This stops the wind from pushing the foresail around the front of the forestay.

When these steps are complete, the helmsman can steer the boat to its new position. The boom will be pushed over by the wind as far as the mainsheet allows and can be then let out as far as needed.

This needs to happen fairly speedily to prevent the wind catching it and slamming it the other way especially in swells. The foresail can also be let out to its appropriate level.

VIDEO: TACKING AND GYBING

Crash jibing.

Crash jibing is the reason why some sailors dislike jibing. It occurs when the wind, coming from behind, catches the boom on the wrong side and slams it from one side of the boat to the other.

Not only can this send the boat lurching over and breaking the boom, it can also catch crew members unaware, knocking or even killing them.

Crash jibing usually doesn’t occur while jibing. Rather, it occurs when the boat jibes itself. This can happen when sailing very close to the jibing point if the wind changes while using auto-pilot or when waves unbalance the sails and boom.

Crash jibing can be avoided by using a rope to tie the boom to a cleat or using several other safety methods.

KEEPING YOUR SPEED UP

While jibing can (and should) be done slowly and with you in control, tacking too slowly won’t work. Since sailing directly into the wind kills your speed, the helmsman should complete the turn through the wind fairly quickly and let out the main straight away.

It’s also crucial to have enough boat speed going into the tack. Otherwise, you may not make it through at all!

If you require extra boat speed, the helmsman can change course away from the wind slightly before the tack, increasing the power of the sails. When the speed is enough, they can then tack successfully. A tack with minimum lost speed is a racing tack and quite a skill to hone.

EMERGENCY TACKING

Occasionally, you may need to suddenly alter course in a way that results in a tack. This might happen if you see something in the water or discover yourself on an immediate collision course. The main consideration in an emergency tack is that nobody is in the way of the boom.

While far more controlled than a jibe, if you must tack before you can pull the mainsheet in, then shouting a boom warning to crew is the first step. The sails come second to the safety of the boat and crew.

SAFETY TIPS

The most dangerous things in either sailing maneuver are the boom, the changing angle of the boat and lazy sheets whipping as the sails lose power and flap. Many have gone overboard due to a flicking line!

For a successful maneuver, the crew must be informed of what if going to happen. This will likely take the risk out of these dangers and make for a fast tack or a safe jibe.

Mastering the Art of Tacking and Jibing: A Comprehensive Guide

• No Comments

Welcome to our comprehensive guide, where we delve into the art of two fundamental sailing maneuvers: tacking and jibing. If you’re new to the world of sailing, these terms may seem unfamiliar, but fear not, we’re here to demystify them.

Tacking and jibing are essential maneuvers that every sailor, regardless of their experience level, should understand and master. But what do these terms actually mean?

In sailing, the wind’s direction plays a vital role in determining the course and speed of a sailboat. Since a sailboat cannot move directly into the wind, sailors use a technique called tacking to move ‘upwind’ or ‘into the wind.’ Tacking involves changing the boat’s direction by turning its bow (the front of the boat) through the wind, so that the wind changes from one side of the boat to the other.

Jibing (or gybing, as it’s known in some regions), on the other hand, is a maneuver used when sailing ‘downwind’ or ‘with the wind.’ It’s the opposite of tacking and involves changing the boat’s direction by turning its stern (the back of the boat) through the wind, causing the sail to switch from one side of the boat to the other.

Mastering these techniques is essential because they allow sailors to navigate effectively and safely under various wind conditions. Without these skills, your control over the boat is limited and can even lead to dangerous situations, especially in heavy weather conditions. By learning and practicing these maneuvers, you can enhance your ability to steer the boat accurately, boost your confidence on the water, and truly maximize your enjoyment of sailing.

In the upcoming sections, we’ll provide a detailed exploration of tacking and jibing techniques, offering step-by-step instructions, common mistakes to avoid, and practical tips to help you navigate the waters like a pro. Let’s set sail on this exciting journey!

Understanding the Basics

Before we dive deeper into tacking and jibing, it’s crucial to understand some fundamental sailing concepts – namely sailing upwind, downwind, and the points of sail .

When we refer to sailing ‘upwind’ or ‘windward’, we mean sailing in the direction from which the wind is coming. On the other hand, sailing ‘downwind’ or ‘leeward’ refers to sailing in the direction the wind is blowing towards. However, due to the design of sailboats and the physics of sailing, a sailboat cannot sail directly upwind or downwind efficiently. This is where tacking and jibing come into play.

Now let’s talk about the ‘points of sail.’ The point of sail is the boat’s course in relation to the wind direction. There are five main points of sail:

• In Irons (Into the Wind): This is when the boat is facing directly into the wind and can make little to no forward progress.
• Close-Hauled : The closest course to the wind that a boat can sail. The boat sails as tightly as possible towards the wind at roughly a 45-degree angle.
• Beam Reach : The wind is coming directly across the boat. This is often where the boat can achieve its highest speed.
• Broad Reach: The wind is coming from behind the boat, but not directly – it’s off to one side.
• Running (Downwind) : The boat is sailing in the same direction the wind is blowing.

Tacking and jibing are the techniques sailors use to change their direction or point of sail . When you’re sailing upwind (from close-hauled to a beam reach), you perform a series of ‘tacks’ to zigzag your way towards your destination. This is also known as ‘beating.’ Each turn or change of direction where the bow of the boat passes through the wind is a ‘tack.’

When you’re sailing downwind (from a broad reach to running), you perform a series of ‘jibes’ to move from one direction to another. In a jibe, the stern of the boat passes through the wind, causing the sails to switch sides.

In the next sections, we will delve into the step-by-step processes of tacking and jibing, ensuring you can execute these maneuvers with confidence and precision. By mastering these skills, you’ll be well on your way to navigating the open seas more effectively.

The Art of Tacking

Tacking is a fundamental sailing maneuver that allows a boat to move ‘upwind,’ towards the direction from which the wind is coming. Since a sailboat cannot sail directly into the wind due to the forces on its sails, sailors use a zigzag pattern, making a series of turns to progress upwind. Each of these turns, where the bow of the boat moves through the wind, is known as a ‘tack.’

Step-by-Step Guide to Executing a Tack

• Preparation:

Before initiating a tack, ensure you have enough sea room to perform the maneuver safely. Look around for other vessels, obstacles, or shallow water. The crew should be alerted and prepared to move the sails as needed. Once you’re ready to start, you’re sailing ‘close-hauled,’ or as close to the wind as your boat can efficiently sail.

Start by pushing or turning the tiller (or turning the wheel) towards the wind slowly. This action will cause the bow of your boat to head towards the wind, an area referred to as being ‘in irons.’ The sail will start to flap as it loses the wind.

• Completion:

Once the bow has crossed through the wind, quickly bring the tiller back to the central position to stop the turn. The boat should now be on the opposite tack, and the sail will fill with wind again. Adjust the sail for the new tack, and you’re back to sailing close-hauled, but in the opposite direction.

Common Mistakes and How to Avoid Them

• Tacking too quickly: If you turn the boat too quickly, the sail may not have enough time to switch sides, and you could end up stuck ‘in irons.’ To avoid this, remember to make your turn gradually and smoothly.
• Not letting the sail loose quickly enough: If you don’t release the sail at the right time, it can prevent the boat from completing the tack. Make sure to coordinate with your crew (if you have one) to release and then trim the sail at the right times.
• Not using enough momentum: Particularly in light wind conditions, it’s important to enter the tack with enough speed. If you’re moving too slowly, you might not have enough momentum to complete the tack.

Practical Tips for Effective Tacking

• Practice your tacks in various wind conditions to understand how the wind speed and direction can affect your maneuvers.
• Clear communication with your crew can make the tacking process much smoother, especially when it comes to moving the sails.
• Always keep a lookout for potential obstacles, other vessels, or changes in the wind or water conditions.
• Remember, smooth and steady wins the race. Don’t rush the tacking process. It’s better to perform the maneuver slowly and correctly than to rush and make mistakes.

Mastering the art of tacking is a gradual process that comes with practice. But with these steps and tips in mind, you’ll be well on your way to proficiently navigating your sailboat upwind.

Mastering Jibing

Jibing, or gybing, is another vital sailing maneuver, essentially the opposite of tacking. While tacking involves changing the boat’s direction by moving the bow through the wind, jibing entails changing the boat’s course by passing its stern through the wind. This maneuver is most commonly used when sailing downwind, allowing the boat to shift from one ‘gybe’ (or side of the boat the wind is on) to the other.

Step-by-Step Guide to Executing a Jibe

Before initiating a jibe, ensure you have a clear path and enough space to perform the maneuver safely. Inform your crew about the upcoming maneuver so they can prepare to adjust the sails. At the start of a jibe, your boat should be on a ‘broad reach,’ with the wind coming from behind the boat and off to one side.

Gently turn the tiller or wheel away from the main sail. This action will cause your boat to bear away from the wind and the stern will start to move through the wind. As the boat turns, the sail will begin to move across the boat.

As the stern passes through the wind, the sail will quickly shift from one side of the boat to the other. It’s essential to control this move to prevent damage or injury. Once the sail has filled on the new side, straighten the tiller or wheel and adjust your course for the new gybe.

• Allowing the boom to swing across uncontrollably : This is a frequent and potentially dangerous mistake. Always control the boom’s movement using the mainsheet during the jibe.
• Jibing unintentionally: This can occur if the boat accidentally turns its stern through the wind. To avoid this, keep a firm grip on the tiller or wheel and maintain awareness of your course relative to the wind.
• Not preparing your crew : Everyone on board needs to know when a jibe is about to happen. The quick movement of the boom can cause injuries if crew members aren’t prepared.

Practical Tips for Safe and Effective Jibing

• Always be mindful of the boom. Ensure all crew members are aware of its movement during a jibe to avoid injuries.
• Practicing jibing in lighter wind conditions can be a good way to get the hang of the maneuver before attempting it in stronger winds.
• Clear and prompt communication with your crew is vital, especially when adjusting the sails.
• It can be useful to plan your course after the jibe beforehand, so you can quickly adjust and keep the boat moving smoothly.

Jibing, like tacking, is an essential skill in the sailor’s toolbox. While it can seem daunting at first, especially given the speed at which the sail moves across the boat, with practice, patience, and adherence to safety measures, you can master this maneuver and sail downwind efficiently.

Tacking vs. Jibing

Tacking and jibing, though seemingly opposite maneuvers, are two sides of the same coin – both are ways to change the direction of a sailboat relative to the wind. The primary difference lies in which part of the boat (bow or stern) passes through the wind and whether the boat is moving upwind (tacking) or downwind (jibing).

Comparing and Contrasting the Techniques

• Direction relative to the wind: Tacking is used when you want to move upwind, in the direction the wind is coming from. On the other hand, jibing is used when sailing downwind, in the direction the wind is blowing towards.
• Part of the boat through the wind: In tacking, the bow of the boat moves through the wind, causing the sails to switch sides. In jibing, the stern moves through the wind, again causing the sails to switch sides.
• Speed of the maneuver: Tacking generally involves a slow and steady change of direction and the sails move across the boat relatively slowly. In contrast, jibing is a faster maneuver where the sail moves across the boat quickly, and if not controlled properly, can be quite dangerous.

When to Use Each Technique

The sailing conditions, including the direction and strength of the wind and your desired course, determine whether tacking or jibing is the appropriate maneuver:

• Tacking: T his is the maneuver to use when you want to sail towards the wind (upwind). Tacking is typically the safer and more controlled of the two maneuvers and can be used in a wide range of wind conditions. However, in very light wind conditions, maintaining enough speed to complete the tack can be challenging.
• Jibing: Use this maneuver when you’re sailing with the wind (downwind). It’s important to note that jibing should be performed with caution, particularly in strong wind conditions, as the boom and sail can swing across the boat with significant force. In heavy winds, it may be safer to perform a series of ‘chicken jibes’ (essentially, tacking instead of jibing to change direction when downwind) to keep the boat under control.

By understanding the differences between tacking and jibing and knowing when to use each technique, you can sail more effectively and safely, no matter the wind conditions. Up next, we’ll discuss why regular practice of these maneuvers is crucial and suggest some drills to help you improve your tacking and jibing skills.

Practice Makes Perfect

While understanding the theory behind tacking and jibing is essential, sailing is a hands-on activity, and there’s no substitute for getting out on the water and practicing these maneuvers yourself. Regular practice allows you to build muscle memory, refine your technique, and learn how to respond to different wind and water conditions.

The Importance of Regular Practice

Practice is the cornerstone of mastering any skill, and sailing is no different. Each sailboat has its quirks and unique handling characteristics, and every change in wind and wave conditions presents a new set of challenges. By practicing regularly, you get to know your boat and how it responds under different conditions. Regular tacking and jibing drills will make these maneuvers become second nature, allowing you to perform them safely and efficiently even under pressure.

Drills to Help Improve Tacking and Jibing Skills

• Figure-Eight Drill: This drill involves sailing in a figure-eight pattern, alternating between tacking and jibing at each turn. This exercise will help you practice transitioning smoothly between different points of sail.
• Windward/Leeward Drill : Set up two markers (buoys, if available) in a downwind/upwind configuration. Practice sailing upwind through a series of tacks and then downwind with a series of jibes.
• Man Overboard Drill : Although this is primarily a safety drill, it also provides good tacking and jibing practice. Simulate a man-overboard situation and practice maneuvering your boat to ‘rescue’ the overboard crew member.

Safety Considerations During Practice

Safety should always be your top priority when practicing these maneuvers. Here are some considerations to keep in mind:

• Monitor Weather Conditions : Check the weather forecast before you go out and keep an eye on the sky. Don’t practice tacking and jibing for the first time in strong wind or rough water conditions.
• Wear Appropriate Safety Gear : Ensure everyone on board is wearing a life jacket. Depending on conditions, you might also need harnesses and tethers, particularly for crew members moving about the boat during tacks and jibes.
• Be Aware of Your Surroundings : Always keep a lookout for other boats, obstacles, or shallow water. Remember that other vessels may not anticipate your maneuvers, so always give way as required.
• Control the Boom : The boom can move swiftly and forcefully during tacks and particularly jibes. Keep clear of its path and control its movement with the mainsheet.

Remember, the key to mastering the art of tacking and jibing is patience and consistent practice. Happy sailing!

Mastering the techniques of tacking and jibing is a crucial part of becoming a proficient sailor. These maneuvers allow you to harness the power of the wind, no matter its direction, and to navigate your sailboat safely and effectively in a variety of conditions. Tacking enables you to zigzag your way upwind, while jibing allows you to change direction efficiently when sailing downwind.

Understanding the theory behind these techniques is only the beginning. Each tack or jibe on the water brings new insights and challenges. From different wind strengths and directions to unique boat characteristics, each situation provides a valuable learning experience.

The importance of regular practice cannot be overstated. Through a combination of drills and real-world experience, you’ll find your skills and confidence growing. It is through these repetitive actions that the maneuvers of tacking and jibing will become second nature, allowing you to focus on other aspects of sailing.

Safety is paramount when performing these maneuvers. Always be aware of your surroundings, control the movement of your sails, and ensure all crew members are prepared and equipped with appropriate safety gear.

In the end, continuous learning and practice are at the heart of sailing. Even the most experienced sailors will tell you that they learn something new every time they go out on the water. So embrace the journey and remember – the art of tacking and jibing is not just about changing your course; it’s about mastering the wind and waves, understanding your boat, and developing as a sailor.

What are tacking and jibing?

Tacking and jibing are sailing maneuvers used to change the boat's direction relative to the wind. Tacking involves turning the bow (front) of the boat through the wind, changing from one tack (or side) to the other. Jibing is similar but involves turning the stern (back) of the boat through the wind.

Why is mastering tacking and jibing essential?

Mastering tacking and jibing is crucial because these maneuvers allow you to sail effectively and safely in any direction, regardless of where the wind is coming from. They are fundamental skills for any sailor and will enhance your overall sailing experience.

What is meant by sailing upwind and downwind?

Sailing upwind, or beating, means you're sailing against the direction the wind is coming from. Sailing downwind, or running, means you're sailing in the same direction as the wind. Tacking is generally used when sailing upwind, while jibing is used when sailing downwind.

What are the steps involved in executing a tack?

The key steps involved in tacking are the preparation (alerting the crew, positioning the boat), the execution (turning the boat into the wind, switching the sails), and completion (settling onto the new tack). Each step requires specific actions from the crew.

What are some common mistakes in tacking and how can they be avoided?

Common mistakes during tacking include not steering a steady course, turning the boat too quickly or too slowly, and not coordinating the sail trim with the turn. These can be avoided by good communication, practicing the maneuver, and understanding how your specific boat responds to helm and sail adjustments.

How is jibing different from tacking?

Generally, you should tack when you're sailing upwind and want to change direction, and jibe when you're sailing downwind and want to change direction. The conditions, such as wind strength and direction, and the boat's course will also influence this decision.

What are some drills to improve my tacking and jibing skills?

Drills such as the figure-eight drill or the windward/leeward drill can be very effective. These involve repeated tacking and jibing maneuvers, helping you refine your technique and build muscle memory.

What safety considerations should I bear in mind while practicing?

Always check the weather conditions before heading out, wear appropriate safety gear, stay aware of your surroundings, and control the boom carefully during these maneuvers, particularly when jibing. Safety should always be your top priority when out on the water.

A Full Guide to The Jib Sail And How To Use It

Most cruising boats today have a sail plan consisting of at least three sails: A mainsail, a headsail, and a light-wind sail.

The Jib sail (along with its sister, the Genoa) is one of the most widely used headsails on modern sailboats in combination with a larger mainsail. It is very versatile and easy to use in different configurations throughout most weather conditions. 

In this article, I want to explain the Jib in detail and talk a bit about how it works and how we rig and trim it to get the most performance out of the boat. I’ll also show you each part of the sail and its materials before explaining how it differs from other headsails like the Genoa .

Finally, I’ll finish with some tips on maintaining the sail properly to make sure it last as long as possible.

Well, shall we get started?

What is a Jib sail, and what do we use it for?

The Jib is a triangular sail that does not overlap the mainsail. It is typically between 100% and 115% of the foretriangle size and is commonly seen on modern vessels with fractional rigs.

The foretriangle is the triangular area formed by the mast, deck, and forestay. Learn more terms here .

Like other headsails, the Jib is usually rigged on a furling system attached to the forestay , making it easy to operate. The Jib can also be rigged with a self-tacking system, making upwind sailing easy for you, whether you want to cruise solo or with your friends.

How the Jib works on a sailboat

The Jib provides a sail area forward of the mast, allowing the boat to be steered and balanced effectively.

The curved shape of the sail creates a pressure differential. The outer, more convex side (leeward side) has a lower pressure than the inner, concave side (windward side). This pressure differential generates lift, which translates into forward propulsion, much like how an airplane wing produces lift. 

How to rig a Jib

You can rig the Jib on either a furling system or directly to the forestay. Most modern sailing boats are equipped with a furling system, which is a long sleeve that runs from the top of the mast down to the bow and attaches to a drum on the bottom and a swivel on the top. 

Take a closer look at this step-by-step process on how to rig the Jib to sail onto a furling system:

• Feed the Jib’s luff into the track on the furler’s sleeve with the top of the sail first and connect the head ring on the sail to the chackle on the swivel.
• Attach the Jib halyard to the swivel and hoist the sail up. 
• When the sail is hoisted almost all the way to the top, you attach the sail’s tack to a shackle on the top of the drum. 
• Put the halyard on a winch and winch it tight.
• Now you have to manually roll up the sail around the forestay and tie on the two sheets to the clew of the sail.
• Lead the two sheets on each side of the vessel’s side decks through the sheet cars, turn blocks, and back to the winches.
• Now that the sail is furled away, we need to tie the furling line onto the drum. You have to figure out how the furling line attaches, as it differs from system to system.
• Once the furler line is attached to the drum, ensure that it can wrap itself up freely.
• Pull the sail back out using one of your sheets and monitor that the furling line wraps on nicely.
• Leed the furling line through the blocks and funnels, through the jammer , and leave it next to the winch.
• Furl the sail away again using the furling line and ensure that the sheets run freely as you monitor your sail getting wrapped nicely around the forestay.
• Secure the furler line jammer and tidy up your two sheets. Make sure to secure the sheets around the winches.

So, you see now why most boats use furling systems? It is easy! Many larger sailboats even have electrical furlers, removing the need for the furling line.

How to use, reef, and trim a Jib

To use the Jib, you wrap the furler line around the winch, open the jammer, and pull on either of the sheets, depending on which tack you are sailing on. You should hold on to the furler line to prevent the sail from unfurling itself uncontrollably, especially in strong winds. Trying to catch it if it starts running can injure your hands, so be careful! I’m speaking from experience here; burned hands are “No bueno.”

You can now unfurl the entire sail or a part of it. Once the full sail, or the amount you desire, is out, adjust your car position and tighten the sheet.

How to reef a jib

You do the opposite as the above to reef the sail or furl it back in. 

Ease off the working sheet, but keep it on the winch. At the same time, pull in on the furler line either manually or on the winch. Remember to move the cars forward and re-tighten the sheet if you are reefing away only a part of the Jib. 

How to trim a jib

Adjusting the sheet cars and sheet tension is important to obtain an optimal sail shape in the Jib. Finding this balance is what we call  sail trim . I’m not going too deep into sail trim here, as it is a topic for itself, which will require a separate article,.

But here is a rule of thumb:

You want the leech and foot of the sail to form an even “U” shape on any point of sail . When sailing upwind, you usually move the car aft. When bearing off the wind, you move the car forward.

The goal is to apply even tension on both the foot and the leech. When you reef the sail, you’ll also want to move the car forward to adjust for the reduced sail area. Sailing downwind doesn’t require the same fine-tuning as upwind sailing.

Four tips for sailing upwind:

• Winch up the jib sheet until the leech stops fluttering and the foot has a nice, even “U” shape. 
• You must move the sheet car forward if the foot is tight and the leech flutters.
• Move the sheet cars aft if the leech is tight and the foot flutters .
• If the wind increases and the boat starts to heel excessively, you can either ease off the sheet or adjust your course more head to wind. 

You should play around and experiment with sail trim, as every boat behaves differently. Trimming sails is an art that takes time to master. Staysails, Jibs, and Genoas are trimmed the same way, but the car positions will be different due to their size and shape differences. Once you learn how to trim a Jib, you’ll be able to trim any headail and even a storm jib or a spinnaker.

Sailing with more than one Jib

Sailing with multiple jib sails can be beneficial on longer downwind passages. Most furling systems have two tracks, allowing you to have two Jibs on the same furler, making this setup easy to reef. You can do the same with Yankees and Genoas, depending on what you have available in your boat.

Some sailboats have two or more forestays, allowing them to have two individually furled Jibs. This is usually called a cutter rig. Most Cutter rigs, however, use a Staysail on the inner forestay and a Yankee sail on the outer, but this versatile rig allows you to experiment with many setups.

Exploring the different parts of the Jib

Head: The head is the top corner of the Jib. It typically has a ring in the top corner that attaches to the Jib halyard or the top swivel for furling systems.

Leech: The leech is the aft part of the rib, located between the clew and head. 

Luff : A Jib’s luff is the front part between the tack and head. Jibs can be equipped with  luff foam  to help maintain their shape when partially reefed on a furler.

Clew : The clew is the aft lower corner of the jib where the sheets are attached.

Tack : The tack is the lower, forward corner of the Jib. The tack is connected to a furler drum on the forestay on most sailboats. Vessels using traditional hank-on headsails connect the tack to a fixed point on the bow.

Foot : The foot of the Jib is the bottom portion of the sail between the clew and the tack.

Telltales: Telltales are small ropes, bands, or flags attached to the front of the Jib’s leech to help us understand how the wind affects the sail and allow us to fine-tune the trim for optimal performance.

Commonly used materials for the Jib

The most common material used for Jib’s today is Dacron woven polyester, followed by CDX laminate due to the relatively affordable price. Continuing up the range, we find woven hybrids like Hydranet, Vectran, Radian, and other brands.

Then, we have advanced laminates with Aramids, carbon, kevlar, and more exotic materials. At the top of the spectrum, we find the latest technology in DFi membrane sails like Elvstrøms EPEX or North Sails 3Di, which comes at a premium price tag.

These days, however, modern technology has given us warp-oriented woven cloth, which is becoming a popular option due to its increased ability to keep shape over time without stretching as much as traditionally cross-cut dacron sails. ProRadial, made by Contender and Dimension Polyant, is a good example. North Sails has an excellent article that goes in-depth on sail materials.

The difference between a Jib and a Genoa

The difference between a Jib and a Genoa is that the Jib is a headsail that does not overlap the mainsail, while the larger Genoa is designed to overlap the mainsail. While the smaller Jib is excellent at pointing upwind and easier to handle, the larger Genoa excels on any points of sail with the wind behind the beam.

Genoas are usually larger than 115% of the  foretriangle , with sizes ranging from 120% to 150%. They are often used on yachts with masthead rigs and smaller mainsails but are also common on fractional rigs.

How to Maintain and Care for Your Jib Sail

Good maintenance and care of your Jib will ensure optimal performance and minimize wear and tear. Check out these tips on how to maintain and protect your Jib:

• Rinse the Jib with fresh water regularly and leave it up to dry before packing it away. Proper drying will prevent moisture and mildew.
• Give the sail a service once a year. Check for any damaged seams and repair them if necessary. If there are any chafing marks, reinforce the sail with patches on chafe points and add shafe guards to the equipment it rubs against.
• Protect the sail from UV rays by keeping it packed away when not in use. A furling Jib can be protected by adding a UV strip to the foot and leech.

I also wrote an article on how to make sails last longer .

Final Words

We have talked a lot about the Jib’s features and how it works in this article. I recommend you to head out and set sail to get some experience and play around with your sails. If you don’t have a boat, chat around in your nearest marina; someone will for sure bring you along for a sail. I know I would.

Remember to experiment with sail trim and practice tacking and maneuvering the vessel with the sail on both the port and starboard sides.

FAQ – The Jib Sail Explained

When to use a jib sail.

The Jib is an excellent sail for most conditions, especially when cruising at any angle towards the wind. The Jib has a benefit over the Genoa in strong winds as it is easier to handle, and its smaller size makes it more effective than a reefed Genoa when sailing to windward. 

Can you sail with just the Jib?

It is possible to sail with just the Jib alone, and it works exceptionally well downwind on deep angles where the mainsail usually would have blocked off the wind. 

Can you sail upwind with just the jib?

It is possible to sail upwind with just the Jib, but most sailboat owners prefer to balance their boats by flying their mainsail combined with theiJib when sailing to windward.

What is the difference between a Genoa and a Jib?

The Genoa is different from a Jib sail as it is larger and overlaps the mainsail, whereas the Jib is smaller and does not overlap the mainsail.

How to Rig a Self-Tacking Jib for Free!

You may not have seen or even heard of a self-tacking jib before. They’re usually only found on luxury sailboats. But that’s exactly what one is, a headsail that sheets itself when you tack. You don’t have to cast off the working sheet and haul in the lazy sheet on every tack. In fact, after you set it up, you don’t have to touch the sheet again while sailing. You just push the helm to lee, come about as you normally would, and the jib passes through the fore triangle by itself and stops on the new lee side at the same sheeting angle as it was before the tack. I set one up for free and you can too.

Before I continue, a bit of legal housekeeping. This post contains affiliate links. That means I receive a small commission if you make a purchase using those links. Those commissions help to pay the costs associated with running this site so that it stays free for everyone to enjoy. For a complete explanation of why I’m telling you this and how you can support this blog without paying more, please read my full disclosure .

Self-tacking headsails are becoming more and more popular on high-end cruising yachts as designers strive to remove as much effort from sailing as possible with headsail furlers, in-mast mainsail furling, electric winches, autopilots, and more. Seems it won’t be long before sailboats are fly-by-wire like airplanes and driverless cars. How lazy will we get?

But there are practical benefits to a self-tacking jib if you:

• Are single-handed or short-handed on crew.
• Are short tacking through a narrow passageway.
• Have a broken jib car or winch that makes normal tacking impossible or dangerous.
• Or your crew are seriously chilling (lazy) and you’d rather not have to mind the headsail.

A selfie (tacker) you can really use

The basic principle of a self-tacking jib is simple; a means for the clew of the jib to remain sheeted throughout its arc of travel from one side of the sailboat to the other during tacks. Commercial self-tacking systems accomplish this with an arc-shaped track mounted to the foredeck. The jib clew is attached to the track by a single sheet to a car that glides freely on the track like a traveler. The sheet leads to the cockpit where the skipper can adjust the jib shape by trimming the sheet. Such systems can cost many hundreds of dollars to retrofit to a conventional yacht.

The picture below shows the system with a thick red line that I will describe and it cost me nothing new to set up.

Instead of a track fixed to the deck, this system uses a block temporarily fixed to the jib clew. It reuses one of the headsail sheets you already have to form a bridle on the foredeck for the block to ride on. The other headsail sheet is not used.

The only other parts you need are two turning blocks. They can be snatch blocks that you keep on hand for miscellaneous jobs, your spinnaker sheet blocks if they’re portable, or they can be permanent blocks that you install just for this purpose (in that case, your system won’t be free). Heck, even two carabiners will work. If you only have one block or carabiner, reave the sheet directly through the clew grommet in step 2 below instead and attach your block or carabiner to the side deck where it can lead the sheet. The clew will have a little more friction but not enough to keep it from working.

When I want to set up the jib for self-tacking, I just move my existing spinnaker sheet blocks forward from the aft coamings to midship. I won’t be flying the spinnaker at the same time so they won’t be in use anyway. I like these 40mm web attachment style blocks from Nautos . They’re high quality, inexpensive, and work great. Instead of lashing them with webbing, I use 5/32″ dyneema loops or soft shackles.

For easy, versatile, and economical ways to attach these blocks to almost anything like you see in the pictures here, check out the continuous loops of dyneema that I describe in How to Rig a Cruising Spinnaker in 4 Stingy Stages and  DIY Soft Shackles for Quick and Easy Headsail Changes .

This self-tacking setup works best with a small headsail. I set up my 110% jib this way and it works okay. A larger headsail would not work. A 90% jib, storm sail, or trysail would work even better. That’s because, in order for the jib to set as flat as possible, the foot of the sail should be no longer than the distance from the sail’s tack to the jib sheet bridle.

Do it your self-tacker

To rig a self-tacking jib:

1. Tie one end of the sheet to a point on the deck approximately abeam of the mast and as far outboard as possible. On a C-22, a forward stanchion base is a good place. If you have a toerail, you have lots of choices and can adjust the bridle position for the best sail shape. The picture below (taken from the foredeck looking aft) shows the middle of my single sheet tied to the starboard forward stanchion base. The lazy half of the sheet is leading aft. The working half of the sheet leads out of the picture frame to the right. I keep a soft shackle tied to an alpine butterfly knot in the middle of my headsail sheet where I attach the clews of my headsails. I describe this more in DIY Soft Shackles for Quick and Easy Headsail Changes . That soft shackle is tied to the stanchion base here.

2. Lead the working end of the sheet to the foredeck and reave it through one of the turning blocks that you have attached to the jib clew. The picture below shows one of my spinnaker sheet blocks tied to the jib clew with a simple girth hitch. The continuous loop makes it easy to tie and remove in seconds.

3. Continue leading the sheet across the foredeck to the opposite point on the toerail or stanchion base and reave the sheet through the second turning block (or carabiner) that you attach there. The picture below (taken from the foredeck looking aft) shows the block tied to the port forward stanchion base.

4. Continue leading the sheet aft and through the jib car block as usual. Wrap the sheet a couple of turns around the winch and cleat it off as usual, leaving a couple feet of slack at the jib clew.

That’s all there is to it. Now you just need to trim the sheet out on the water.

Get your self-tacker into shape

To trim the self-tacking sheet:

• While pointed straight into the wind, raise the jib as you normally would. If you normally use one, the self-tacker works best without a pendant to raise the tack off the deck. You want the sail to open up as much as possible and to do that it needs to be as low as possible.
• Bear off the wind slowly until the jib fills.
• Trim the self-tacking sheet to get the best shape possible. Ease the sheet out and the clew will rise, the sail will twist, begin to luff, and spill air. Pull the sheet in and the clew will pull toward the deck, hook the sail toward the mast, and form a full, baggy shape. Experiment with your particular setup until you find the optimal shape that you can get when rigged this way for your wind conditions.

You probably won’t be able to get a nice, flat, foil shape, especially with a working jib but it will still work. I’ve made 4.5 knots with this setup in 10-15 mph winds and that was with a reefed mainsail and dragging a wad of weeds the size of a basketball wrapped around my keel cable. Temporarily suppress the rule in your mind that says you have to trim the headsail flat when sailing upwind. You can pull the rule back out when you revert to a conventional headsail setup.

When it comes time to tack, just announce “helm’s a-lee!” and come about. The clew block will roll across on the bridle that you have tied across the deck and the jib will set on the other side by itself.

When not to be self-centered

There are a few caveats that come with this technique:

• It works best in medium airs due to the compromised sail shape. Light airs are too weak to develop much forward power with this shape. The sail also isn’t flat enough for safe sailing in heavy airs. But if an unexpected gust comes up, you can blow the jib by casting the sheet off at the winch like you normally would.
• It doesn’t work well downwind because the sail is held too close to the center of the boat where it falls in the mainsail shadow. So use this setup upwind only or in very short downwind runs.
• You won’t be able to point very high into the wind, also due to the sail shape. Consequently, you won’t make much upwind progress if that’s your course. It’s best used when you’re casually daysailing or turning laps between two points 180° opposed. It works great for that.
• You can’t heave-to when set up this way because you can’t backwind the jib. It will just cross the foredeck and you’ll wind up tacking. To heave to, you have to reset your sheets to a conventional setup.

I think this is an interesting technique that’s useful in specific conditions. Racers and other sail trim experts may scoff and call it a dumb trick. Let them, but give it a try sometime and consider it another tool in your bag of sailing skills. You shouldn’t need to buy anything (or very little) to set it up and you’ve got nothing to lose by trying but a little of your time. I bet that if you set it up right, you’ll be pleased with how much more relaxing it can make sailing. Especially if you don’t have a particular destination in mind and you don’t care how fast you get there. Isn’t that some of the best of times to be had when sailing?

Looks good – looking forward to trying it out. Thanks Mr. $tingy!

I may have missed something, but I don’t see how the self tacking headsail can be adjusted to allow for heave to. To me, that’s one of the most important maneuvers a sailor need to have under his/her belt.

You’re right, Bill. I forgot to mention that as one of the caveats. You can’t backwind the jib when setup this way without first going forward and moving the normal clew knot back to the clew.

Just got round to reading this – what a great idea! Will try this next time I take Tamariu out – thank you $tingy, another winner!

I’ve recently sold off the last of my salt-water navy in favor (at age 81) of returning to lake sailing where the hint of menace that added spice to my coastal adventures for fifty years is blissfully absent. After restoring a derelict Rhodes 19 and launching her last summer, I quickly realized that instead of tacking every hour or two or three as on Penobscot Bay, I was coming about every five or ten minutes. Time for a self-tacking jib, but I am unwilling to spring a few grand for a Hoyt or whatever, I’ve been looking high and low for an easy solution for this matter. Bingo! Today I discovered The $tingy Sailor and this great article. I’ll be putting this great plan into action next week, and every time I call out “hard a-lee” this coming summer long, I’ll thank you that all it means for the crew is “hold onto your drink while I come about”. Ahhh…

Sail on, Eliot!

Nice trick, nice explanation, good warning of caveats. A riggig to try in my sailboat. Thanks!

Maybe a silly question, but I have a roller furler, not a hank on headsail. Is it still possible to use this set up with a furler? I imagine that you would just slack the sheet as you furl the sail. I don’t think the the clew block would be an issue. Any thoughts?

It shouldn’t be a problem. Give it a try!

Well, I rigged up this self tacking jib on my boat and love it!! It’s so much easier having guests aboard without them all constantly moving around to grind the winches and pull lines. I have it set up on a furler which makes the job even easier. The sail luff stops just before the mast, so it’s perfect. I am loving the ease of it! Thank you so much for this great idea!

I will try it on my 1977 Hunter 27 with 85% hank on jib. Thank you.

Thanks – Extremely interesting, and very clear!

From the introducing picture you can already see that this doesn’t work. In the picture the jib maybe uses 30% of its efficiency on a beat to windward. A real self tacking system gets 100 % out of the sail size. Needs a track and a sail that is designed low enough at the clew. A keelboat can be tacked slowly, so you have time to pull the jib sheet tight before the jib fills in the tack. We rarely use the winch handle on a J/80 while racing (international level) in up to 30 knots.

And yet, this system DOES work. I didn’t claim that it would work as well as a “real” self-tacking system and I state the limitations in the article. But for the average recreational sailor (not J/80 racers) that doesn’t need and can’t afford an engineered system, it works well enough to be an option in some situations.

Greetings , thanks for a very interesting article. I’m brand new at sailing just spent a year restoring a 17ft Proctor Pirate , hoping to launch next month so I’m looking all over the net for articles on sailing. I must add this one I am going to try for sure . Looking forward to more sailing info. Thanks for this =) Phill

Just out of curiosity, was the C-22 you were referring to a Catalina 22? We have one also, and I’m hoping a self-tacking jib will make my wife more amenable to cruising along the Southern California coast with our 110 percent jib. Also, was there a link for the soft shackle?

Yep, C-22 is shorthand for Catalina 22. You can read my post about soft shackles at DIY Soft Shackles for Quick and Easy Headsail Changes

Hi, Flying Scot (T) sailor writing. Just came accrost your article about the self Tacking Jib for free! Like’d it very much! Very clear and good directions. Do you think rig will work on my Flying Scot(t) ? Thanks. Flying Scot(t) from Syracuse NY.

Hi, Scott Because the mast of the Flying Scot is so far forward, it would only work with a headsail that doesn’t overlap the mast.

On a furling headsail, can this be rigged at the dock and the headsail rolled up until it’s time to unfurl? Hard for me to visualize how that would look.

Yes, works just the same but instead of having knots at the clew, you have a block.

JIBE SET: HOW TO DO IT RIGHT

If the angle of the downwind leg requires an immediate jibe, you’ll need to learn how to do a jibe set. Jibe sets are more difficult than bear away sets, because they require carefully coordinated crew work. Also, you must wait until after the jibe to set the pole. Since the pole helps the spinnaker fill by holding it away from the boat and other sails, there are several details critical to a successful jibe set

Many crew have two tasks in the process, so practice is vital. To keep it simple, we’ll assume we’re approaching the mark on starboard, bearing away, and jibing to sail the next leg on a port broad reach.

Set Up (during final approach)

Hook up the spinnaker on the starboard side, as far forward as possible. Set up the pole on the port side of the forestay—since it will be used once you jibe to port—with topping lift, downhaul, and guy in place. Make sure the guy is not fouled. The topping lift can be rigged under the jib sheets. (Alternatively, if it is long enough, it can be rigged outboard of the jib to port.)

As you round the mark and bear away, start the hoist. At the same time, pull the sheet (on the starboard side) just far enough to separate the spinnaker clews.

Next, jibe. Make sure you jibe the jib and ease out the old (port) jib sheet; then raise the spinnaker pole. Once the pole is up, trim the guy square with the wind. As soon the spinnaker is fully hoisted, trim the sheet and drop the jib.

You can execute a jibe set without rigging a pole. Sometimes it is faster and easier this way, particularly if the decision to jibe set was a late one, and you don’t have time to make sure the pole is hooked up cleanly.

In this variation the foredeck crew acts as the pole, hand holding the guy outboard until the mast crew can hook up and set the pole. This is not recommended in heavy air.

Like jibe sets, tack sets do not allow complete preparation before the set. When tacking right at the mark, the spinnaker pole cannot be set until the tack is complete.

Prepare the spinnaker as usual, and hook up the pole but do not raise it. As you round the mark, raise the pole and hoist the spinnaker simultaneously. Have the foredeck crew lift the pole while the guy trimmer tails the topping lift. Tension on the guy will prevent the pole from going up, so do not pull the guy until the pole is set. Meanwhile, the mast crew can jump the halyard while the pit crew tails.

Building speed with the main and jib as you hoist the spinnaker is critical to a successful tack set. Proper trim can prevent you being passed by boats carrying a full head of steam into the mark.

What’s a Sailboat Jib? (A Comprehensive Guide)

Are you an experienced sailor looking to learn more about your sailboat? Or are you a beginner looking for a comprehensive guide to help you get started? If so, you’ve come to the right place! In this article, we’ll discuss the basics of sailboat jibs and how they help you sail smoothly and efficiently.

We’ll cover what a jib is, the purpose of a jib, the different types of jibs available, how to rig and trim a jib, the benefits of using a jib, and some tips for setting and trimming a jib.

Whether you’re a beginner or an experienced sailor, let’s get started learning more about sailboat jibs!

Table of Contents

Short Answer

A sailboat jib is a triangular sail that is set at the front of a sailboat.

It is usually attached to the forestay, a cable that runs from the bow of the boat to the mast.

The jib helps to balance the mainsail and increases the sailboat’s ability to sail close to the wind.

The jib is often the smallest sail on a sailboat and is often used for light air sailing.

What is a Sailboat Jib?

A sailboat jib is an essential part of any sailing vessel’s rig.

A jib is a triangular sail that is set at the front of the boat, usually between the mast and the bow.

It is the second most important sail on a sailboat and is typically used to help the boat turn and maneuver more efficiently.

The jib is an important part of a sailboat’s rig and is often used in combination with the mainsail to maximize the boat’s performance.

The jib is usually the first sail to be set up.

It is attached to the forestay, a line that runs from the bow of the boat to the mast.

The jib is adjusted to the desired angle and is held in place by a series of blocks that allow it to be adjusted to different angles.

The jib is also connected to the mast by a halyard, which is a rope that is used to raise and lower the sail.

The jib is an important part of sailing because it allows the boat to turn more efficiently.

The jib provides extra lift and power to the boat, which can be used to turn the boat more quickly and to increase the speed of the boat.

The jib also helps to balance the boat, allowing it to sail more smoothly and easily.

The jib also helps to improve the boat’s performance in light winds.

A boat with a jib will be able to sail in much lighter winds than a boat without one.

This is because the jib acts as a sort of “wing” that is able to catch the wind, allowing the boat to move forward even in light winds.

In conclusion, a sailboat jib is an essential part of any sailing vessel’s rig.

It is an important sail that helps to increase the boat’s performance, turning ability, and speed.

The jib also helps to balance the boat and allows it to sail in lighter winds.

A sailboat is not complete without a jib, and understanding how to properly rig and manage a jib is essential for any sailor.

What is the Purpose of a Jib?

The purpose of a jib is to provide an additional source of power and lift as a sailboat moves through the water.

Unlike the mainsail, which is a large, open-ended sail attached to the mast, the jib is a triangular sail that is set at the front of the boat, usually between the mast and the bow.

This helps to make the boat more maneuverable and provides additional power in lighter winds or upwind sailing.

The jib also provides additional lift, which reduces the amount of drag created by the mainsail.

This can help a sailboat achieve higher speeds or sail closer to the wind.

Additionally, the jib can be used to balance the boat in different conditions, such as when sailing upwind or when beating into a strong wind.

In essence, the jib is an important part of a sailboat’s rig and is often used in combination with the mainsail to maximize the boat’s performance.

Types of Sailboat Jibs

When it comes to sailboat jibs, there are several different types that you can choose from depending on your needs. The most common types of sailboat jibs are: Genoa jibs, cutter jibs, overlapping jibs, and non-overlapping jibs.

Genoa jibs are the largest type of sailboat jib and are often used on larger sailboats.

They are typically used in combination with a mainsail to help maximize the boat’s performance.

Genoa jibs provide the most power and are usually used in light to moderate wind conditions.

Cutter jibs are a type of jib that is designed for smaller sailboats.

They are typically used in combination with a mainsail to help the boat maneuver more efficiently.

Cutter jibs are usually used in moderate to strong winds and offer less power than Genoa jibs.

Overlapping jibs, as the name suggests, overlap with the mainsail when deployed.

These sails are usually used in light-moderate winds and provide more power than cutter jibs.

Non-overlapping jibs, also known as headsails, are the most common type of jib used on sailboats.

These sails are usually used in moderate to strong winds and provide the most power when compared to the other types of jibs.

Finally, there are also asymmetrical spinnakers, which are specialized sails that are designed to help the boat reach higher speeds.

These sails are typically used in combination with a mainsail and jib to help the boat reach maximum speed.

Asymmetrical spinnakers are usually used in moderate to strong winds and provide the most power when compared to the other types of jibs.

No matter what type of sailboat jib you choose, you’re sure to enjoy the increased performance that it provides.

With the right combination of mainsail and jib, you’ll be able to maximize your boat’s performance and have a great day on the water.

How to Rig a Jib

Rigging a jib is an important step in ensuring a successful sailing experience.

It requires some knowledge of sailing terminology and techniques, but once the basics are understood, it can be done quickly and efficiently.

The first step in rigging a jib is to select the appropriate size for your sailboat.

The size of the jib should be based on the size of your boat and the type of sailing you plan to do.

For example, a larger jib will be more effective when sailing in strong winds, while a smaller jib is better suited for lighter winds.

Once you have determined the size of the jib, you can begin the rigging process.

First, attach the jib halyard, which is the line used to hoist the sail, to the head of the jib.

Next, attach the jib sheets, which are the lines used to control the trim of the jib, to the clew of the jib.

Finally, attach the jib tack, which is the line used to attach the jib to the bow of the boat, to the bow.

Once the jib is rigged, you can begin to adjust the trim of the sail.

To do this, you will need to adjust the tension on the jib sheets.

If the tension is too loose, the jib will not be able to fill with wind properly and you will lose power.

On the other hand, if the tension is too tight, the sail will be over trimmed and you will sacrifice performance.

Finally, you can adjust the angle of the jib in relation to the wind to maximize the power of the sail.

This is known as jibing, and it involves adjusting the angle of the sail in relation to the wind so that the wind is hitting the sail at the optimal angle.

This will maximize the power of the sail and help you turn more efficiently.

Rigging a jib is an important part of sailing, and when done correctly, it can make a huge difference in your sailing performance.

With a little knowledge and practice, you can quickly and easily rig your jib to maximize the power of your sailboat.

How to Trim a Jib

When it comes to sailing, the jib is an important part of the boats rig.

It is a triangular sail set at the front of the boat, usually between the mast and the bow.

The jib helps the boat turn and maneuver more efficiently, and is often used in combination with the mainsail to maximize the boats performance.

But before you can use the jib to its full potential, you need to know how to trim it properly.

Trimming a jib is a delicate process, as the sail needs to be adjusted in order to capture the right amount of wind.

To do this, you will need to adjust the angle of the sail relative to the boat, as well as the tension of the sail itself.

The angle of the sail should be adjusted so that it is parallel to the wind direction.

As the wind direction changes, so should the angle of the sail.

In order to adjust the tension of the sail, you will need to use the jib sheet.

This is a line that connects the jib to the boat and is used to adjust the sails tension.

By releasing or tightening the jib sheet, you can adjust the amount of tension on the sail, allowing it to capture the right amount of wind.

When it comes to trimming the jib, it is important to remember that the sail needs to be adjusted in order to maximize the boats performance.

Adjusting the angle of the sail and the tension of the sail will help you capture the right amount of wind and will ensure that you are getting the most out of your boat.

With a little practice and patience, you can become an expert at trimming a jib.

Benefits of Using a Jib

A sailboat jib can be an incredibly useful addition to your boats rigging.

It helps the boat turn more efficiently, allowing the boat to be maneuvered with greater precision.

The jib also adds stability in windy conditions, helping to reduce the risk of capsizing.

Additionally, a jib will provide additional power while sailing, allowing you to make quicker progress, particularly in light winds.

Finally, having a jib can help to reduce the stress on your mainsail, extending its life and reducing the need for frequent repairs.

In addition to providing more power, a jib can also be used to adjust the course of the boat.

For example, when sailing close-hauled (on a close reach with the wind coming from directly ahead), the jib can be used to increase the boats speed and turn it more quickly.

This is especially useful when tacking or jibing.

Using a jib also helps to reduce drag on the boat, allowing it to move faster and more efficiently.

This is especially important for racers, who need to maximize their boats performance in order to gain an edge over their competitors.

Finally, using a jib can help to reduce the overall weight of the boat, making it easier to maneuver and store.

This is especially useful for smaller boats, which may not have enough room to store a large mainsail.

Tips for Setting and Trimming a Jib

When it comes to sailing, a well-executed jib can make or break the success of the voyage. Setting and trimming the jib is essential for the boat to reach its full potential on the water. Here are some tips for setting and trimming a jib:

1. Before setting the jib, make sure the boat is properly balanced by adjusting the traveler and outhaul. This will help to ensure the jib is set correctly.

2. When setting the jib, make sure to keep the jib sheet tensioned and the jib luff taut. This will help to ensure the jib is properly aligned with the wind and the boat will move forward efficiently.

3. When trimming the jib, make sure to adjust the sheet tension to keep the jib luff taut. This will help to maintain the jibs alignment with the wind and maximize the boats performance.

4. When sailing in light winds, it can be beneficial to use a smaller jib to reduce drag. This will help to keep the boat moving forward in light conditions.

5. Lastly, it is important to remember to furl the jib in strong winds. This will help to reduce the sail area and keep the boat under control in heavy winds.

These tips should help sailors to get the most out of their jib when sailing.

With the right setup and trim, a jib can be an essential part of a successful sailing voyage.

Final Thoughts

A sailboat jib is an important part of a sailboat’s rig and can help to maximize the boat’s performance.

It is a triangular sail that is typically set between the mast and the bow.

It is important to understand the purpose of a jib, the different types of jibs available, and how to rig and trim a jib.

With knowledge of these basics, sailors will be able to make the most out of their sailboats jib and enjoy a more efficient sailing experience.

So, start sailing with more confidence and get to know your jib today!

How to Rig Your Small Sailboat and Prepare to Sail

In this lesson, you will learn how to rig a small sailboat to prepare for sailing. For reference purposes, a Hunter 140 daysailer was used for this learn-to sail tutorial. Before you begin, you can familiarize yourself with the different parts of a sailboat. 

Install (or Check) the Rudder

Typically the rudder of a small sailboat like this one is removed after sailing to prevent wear and tear while the boat remains in the water. You need to reinstall it before sailing, or if it is already in place, check that that it is firmly attached (with optional safety lanyard securing it to the boat).

On most small boats, the top of the leading edge of the rudder has attached pins (called pintles) that are inserted downward into round rings (called gudgeons) attached to the stern. This is rather like the familiar “Insert tab A into slot B.” While the exact configuration may vary among different boat models, it’s usually obvious how the rudder mounts to the stern when you hold the rudder beside the stern.

The rudder may or may not already have a tiller mounted on it. The next page shows how to attach the tiller on this boat.

Attach (or Check) the Tiller

The tiller is a long, thin steering “arm” mounted to the rudder. If the tiller is already attached to the top of the rudder on your boat, check that it is secure.

On this Hunter 140, the tiller arm is inserted in a slot at the top of the rudder, as shown here. A pin is then inserted from above to lock it in position. The pin should be tied to the boat with a lanyard (short light line) to prevent being dropped.

Note that this tiller also includes a tiller extension, which allows the sailor to still control the tiller even when sitting far out to the side or forward.

With the rudder and tiller in place, we’ll now move on to the sails.

Attach the Jib Halyard

Because sunlight and weather age and weaken sailcloth, the sails should always be removed after sailing (or covered or bagged on a larger boat). Before you get started, you have to put them back on (called “bending on” the sails).

The halyards are used to raise both the jib and mainsail. At the sail’s end of a halyard is a shackle that attaches the grommet at the head of the sail to the halyard.

First, spread out the sail and identify each of its corners. The “head” is the top of the sail, where the triangle is the most narrow. Attach the jib halyard shackle to this corner, making sure the shackle is closed and secure.

Then follow the front edge of the sail (called the “luff”) down to the next corner. The luff of the jib of a small sailboat can be identified by the hanks every foot or so that attach this edge to the forestay. The bottom corner of the luff is called the sail’s “tack.” Attach the grommet in the tack to the fitting at the bottom of the forestay -- usually with a shackle or pin. Next, we’ll hank on the sail.

Hank the Jib on the Forestay

Hanking on the jib is a simple process, but it can feel unwieldy if the wind is blowing the sail in your face.

First, find the other end of the jib halyard (on the port, or left, side of the mast as you face the bow of the boat) and keep a good grip on it with one hand. You will be slowly pulling it in to raise the sail as you hank it on.

Beginning with the hank nearest the head of the jib, open it to clip the hank onto the forestay. It will be obvious how to open the hanks, which are usually spring-loaded to close automatically when released.

Then raise the sail a little by pulling on the halyard. Making sure there isn’t any twist in the sail, attach the second hank. Raise the sail a little more and move on to the third hank. Keep working your way down the luff, raising the sail a little at a time to make sure it isn’t twisted and the hanks are all in order.

When all the hanks are attached, lower the jib back down to the deck while you route the jib sheets in the next step.

Run the Jibsheets

The jib sail is positioned while sailing by using the jibsheets. The jib sheets are two lines that come back to the cockpit, one on each side of the boat, from the aft lower corner of the sail (the “clew”).

In most small sailboats, the jib sheets are left tied to the sail’s clew and stay with the sail. On your boat, however, the jibsheets may remain on the boat and need to be tied or shackled to the clew at this stage. Unless there is a shackle on the sheets, use a bowline to tie each to the clew.

Then run each sheet back past the mast to the cockpit. Depending on the specific boat and the size of the jib, the sheets may run inside or outside the shrouds -- the tensile lines that run from the deck to the mast, holding in place. On the Hunter 140 shown here, which uses a relatively small jib, the jibsheets pass from the sail’s clew inside the shrouds to a cam cleat, on each side, as shown here. The starboard (right side as you face the bow)) jibsheet cleat (with the red top) is mounted on the deck just to the starboard of this sailor’s right knee. This cleat secures the jibsheet in the desired position while sailing.

With the jib now rigged, let's move on to the mainsail.

Attach Mainsail to Halyard

Now we’ll attach the mainsail halyard shackle to the head of the mainsail, a process very similar to attaching the jib halyard. First spread the mainsail out to identify its three corners as you did with the jib. The head of the sail, again, is the most narrow angle of the triangle.

On many small sailboats, the main halyard does double duty as a topping lift -- the line that holds up the aft end of the boom when it is not being held up by the sail. As shown here, when the halyard is removed from the boom, the boom drops down into the cockpit.

Here, this sailor is shackling the halyard to the head of the mainsail. Then he can go on to secure the sail’s tack in the next step.

Secure the Mainsail’s Tack

The forward lower corner of the mainsail, like that of the jib, is called the tack. The grommet of the tack is installed at the bow end, usually by a removable pin inserted through the grommet and secured on the boom.

Now the luff (leading edge) of the mainsail is secured at both the head and the tack.

The next step is to secure the clew (aft lower corner) and foot (bottom edge) of the sail to the boom.

Secure the Mainsail Clew to the Outhaul

The clew (aft lower corner) of the mainsail is secured to the aft end of the boom, usually using a line called the outhaul that can be adjusted to tension the foot of the sail.

The sail’s foot (the bottom edge) itself may or may not be secured directly to the boom. On some boats, a rope sewn into the foot (called the boltrope) slides into a groove in the boom. The clew enters the groove first, forward by the mast, and is pulled back in the groove until the whole sail’s foot is held to the boom in this groove.

The boat shown here uses a “loose-footed” mainsail. This means the sail is not inserted into the boom groove. But the clew is held at the end of the boom in the same way by the outhaul. Thus both ends of the sail’s foot are firmly attached to the sail and drawn tight -- making the sail work the same as if the whole foot was also in the groove.

A loose-footed mainsail allows for more sail shaping, but the sail cannot be flattened quite as much.

With the clew secured and outhaul tightened, the mainsail luff can now be secured to the mast and the sail raised to go sailing.

Insert the Mainsail Slugs in the Mast

The mainsail’s luff (forward edge) is attached to the mast, as the jib’s luff is to the forestay – but with a different mechanism.

On the aft side of the mast is a groove for the mainsail. Some sails have a boltrope on the luff that slides upward in this groove, while others have sail “slugs” mounted every foot or so on the luff. The sail slugs, as you can see in this photo just forward of the sailor’s right hand, are small plastic slides inserted into the mast groove where it widens out into a sort of gate.

Again, first inspect the whole sail to make sure it’s not twisted anywhere. Hold the main halyard in one hand during this process – you will be gradually raising the mainsail as you insert the slugs into the mast groove.

Begin with the sail slug at the head. Insert it into the groove, pull the halyard to raise the sail a little, and then insert the next slug.

Before completing this process, be sure you’re ready to go sailing soon after the mainsail is up.

Continue Raising the Mainsail

Continue raising the mainsail with the halyard as you insert one slug after another into the groove.

Note that this sail already has its battens in place. A batten is a long, thin, flexible strip of wood or fiberglass that helps the sail keep its proper shape. They are positioned in pockets sewn into the sail in a generally horizontal direction. In this photo, you can see a batten near the top of the blue section of the mainsail over the sailor’s head.

If the battens were removed from the sail, you would insert them back into their pockets either before beginning to rig the boat or now, as you raise the mainsail in stages.

Cleat the Main Halyard

When the mainsail is all the way up, pull hard on the halyard to tension the luff. Then tie the halyard to the cleat on the mast, using a cleat hitch.

Notice that the mainsail when fully raised holds the boom up.

Now you’re almost ready to go sailing. This is a good time to lower the centerboard down into the water if you haven’t done so already. Note that not all small sailboats have centerboards. Others have keels that are fixed in place. Both serve similar purposes: to prevent the boat from skating sideways in the wind and to stabilize the boat. Larger keels also help lift the boat to windward

Now you should raise the jib. Simply pull down on the jib halyard and cleat it on the other side of the mast.

Start Moving

With both sails raised, you’re ready to start sailing . One of the first steps to getting underway will be to tighten the mainsheet and one jibsheet to adjust the sails so you can get moving forward.

You may also need to turn the boat so that the wind fills the sails from one side. A boat on a mooring, such as shown here, will naturally be blown back such that the bow faces directly into the wind – the one direction you can’t sail! Being stalled facing the wind is called being "in irons."

To turn the boat out of irons, simply push the boom out to one side. This pushes the back of the mainsail into the wind (called "backing" the sail) -- and the wind pushing against the sail will start the boat rotating. Just be sure you’re ready to take off!

The Difference Between Tacking And Jibing (Gybing)

7 real reasons why you should own a sailboat, how to set a sailboat anchor in 5 steps, what do you do when there is no wind.

When I first started out, I remember going through my very first tacks and jibes.  The skipper would call out “Ready About!” and I will admit, I was not ready at all. I watched and listened as more seasoned sailors around me rapidly released ropes free of winches, while others wrapped ropes around other winches.  Ropes were sent flying off the side, and other ropes were hauled in with ferocity, almost desperation. The boat would heel from one side to the other uncomfortably and I lost my balance regularly. My tacking and jibing knowledge was “baptism by fire”, and I had to learn quick.  I found that actually taking part in the process of tacking and jibing sealed my understanding of these two processes. On that trip, I became one of the well-oiled-machine-crew as we tacked and jibed our way up and down the channel. It was awesome!

I hope to break down these concepts in this guide so that you too can get a jumpstart on understanding the difference between tacking and jibing. If you understand the principles upfront, your actual hands on experience will be so much easier.

What is the difference between a tacking and a jibing?  Tacking is how you head upwind , pointing as high into the wind as possible, to keep the sails full.  A jibe is conducted when you are heading downwind . Both involve the processes of turning the boat to change course when the current direction of travel is no longer possible or safe.

But wait…..How can a sailboat go against the wind?

Sailing Against the Wind

In the explanation that follows, I will be assuming the wind is steady and is  coming from one direction only.

When heading upwind, a sailboat is said to be on a tack. Now, by upwind I don’t mean directly into the wind.  Sailboats need to turn away from the wind by about 45 degrees so the the sails can fill with wind. This is about as high as a sailboat can ‘point’ upwind.  The wind will be blowing over one side of the boat, and the other side will not be in the direct wind. The windward side is called the weather rail, the no-wind side is called the lee.

Sailing upwind is possible in the same way flying is possible for an airplane wing. When wind passes by a wing it goes both over the top and under the bottom of the wing. The wing shape is designed so that wind travelling over the wing has to travel further than the same wind going under the wing. This creates lift. You can recreate this by holding the edge of a piece of paper horizontally up to your mouth.  Blowing air at the edge across the “top” side of the sheet. From a hanging down position, the paper will lift and flap in the wind you created. The fast wind flowing across the top of the sheet will cause it to lift.

The same thing is happens as a sailboat tacks upwind.  The only difference is, the lift of the sails is kept contained by securing the loose ends of the sail to the boat by ropes.  These ropes are called sheets.

Just like blowing across the “top” of a horizontal sheet, the wind blows into the forward edge of a sail, creating a wing like shape, and the principles of lift take over.  If you’ve ever watched the America’s Cup sailing races, you will notice that the main sail of the racing sailboats is literally a vertical wing.

There is one more key component to sailing upwind, and that is the keel and rudder.  Without the keel, the sailboat would be pushed sideways by the oncoming wind. The keel enables the boat to establish a line of travel by not allowing the wind to push the boat sideways. The rudder works with the keel, once the boat is in motion, to establish the direction of that line.  

What is Tacking?

Sailboats can’t sail directly into the wind.  They can only head up about 30 – 45 degrees off the angle of the wind.  From a bird’s eye view, sailboats look like they are zig-zagging their way to their destination when they are tacking.  When heading upwind, you will either be on a port tack or a starboard tack. A port tack means the wind is coming over your port (left) side, and a starboard tack is when the wind is over your starboard (right) side.  While on a tack, your sails will likely be close hauled. That means that the sails are pulled in as tight (or close) to the boat as possible. When you find that you need to turn the boat, you will need do a tack. This is the only way to “make way” upwind.  

In a tack, if you point your course too high upwind, your sails will flap like a flag.  Point your course too low, and you may pick up some great speed, but you won’t make any headway upwind.  Effective tacking means finding the balance between pointing high, and maintaining speed.

What is Jibing?

Jibing happens when you are heading downwind.  It should be thought of as turning the stern across the wind, as opposed to turning the bow across the wind.  When you need to jibe the boat, you use the same basic techniques as tacking, only the main and jib sheets are most of the way out.

How to Tack

Tacking is when you change the course of the sailboat by steering the bow across the wind. As the bow is steered across the path of the wind, the sails will fill on the other side, and the boat will heel over the other way.  The boat will now be travelling approximately 90 degrees from the last heading.

There are a few things to coordinate in a successful tack. Communication with your crew is very important.  As the boat approaches an area that the skipper feels is suitable for a tack, he will call out “Ready About!”  The crew then takes position at the winch, ready to let all of the jib sheet go. The skipper will then call out “Coming About!”  This is when he/she will steer the bow aggressively across the wind by about 90 degrees. Now is the time to release all of the jib sheet.  The jib sail will flap like a flag as the bow crosses the wind. This is the time to haul in tight on the other jib sheet. If you time it right, and with enough practice, a good crew can complete a tack with minimal lost speed.  

How to Jibe

Heading downwind, the principles of sailing are a little easier to understand.  The sails are filled with wind and are pushed by it. This is called running, and it is a direct line of travel with the direction of the wind. A sailboat that is running with the wind (or Wing-on-Wing) will have the main on one side of the boat, and the jib on the other.   Running requires the jib and main sheets to be let out nearly all the way. This allows the boom to move out and away from the cockpit, about 90 degrees. The same thing happens with the jib sail. Letting the jib sheet out allows the sail to catch the wind at about 90 degrees.  When the boat course needs to change, the boat is steered in such a way as for the stern to cross the wind. The wind will fill the backside of one of the sails as the boat turns. This can cause the boom to swing quite rapidly from one side of the boat to the other. This is a real danger to your crew if they are not prepared.  Being hit by the boom could be deadly.

If the boom remains in place, the jib will be the sail to backwind and need to be reset. The jib sheet will need to be released from the winch it was on, and hauled in on the other winch, just a bit.  

Running requires a great deal of attention to the wind and to the position of the sails.  It is not easy to keep both the main and jib sail full of wind. Accidental jibing happens all the time.  Many skippers prefer the broad reach as a way to keep under control a little better. Broad reaching is at times faster than running.  It is also a way to let your guard down a bit and relax while making way downwind.

Broad reaching is different than running, in that both of the sails will be on the same side of the boat.  It is not a direct line of travel with the wind, but looks more like a zig zag pattern. Jibing while broad reaching involves the same process as tacking, however the stern of the boat crosses the wind, as opposed to the bow.

Jibing, or gybing, is the act of putting the stern, or rear of the boat, through the wind. This boating technique requires you to move the sails on your boat to the opposite side of the boat so that they catch the wind at a different angle. Jibing can be dangerous because of the velocity in which the sail and boom move across the boat. However, if you follow the right techniques and communicate effectively, you can safely jibe while in a sailboat. [1] X Research source

Performing a Jibe

• Doing this before you turn the boat wheel will prevent the mainsail and boom from swinging across the boat.

Communicating The Jibe

• Alternatively, you can say "Prepare to jibe."

What Is The Jib Sail On A Sailboat?

The jib sail is the triangular-shaped sail that flies forward of the sailboat mast . Jibs can come in all different shapes and sizes, making them fit for a variety of purposes, so they’re important sails to have on a sailboat.

This article will help educate sailors on understanding the purpose and benefits of having a jib sail. We’ll also go over some tips for keeping it in great condition so your sails are always ready for a voyage.

If you’re looking to understand more about the intricacies of your boat then read on to find out all about your jib sail.

Armed with this knowledge, you’ll be prepared for any offshore adventure!

Table Of Contents

What is the jib sail, why is a jib called a jib, do you need a jib to sail, can you sail with jib only, how do you trim a jib sail, different parts of a jib sail, how do you reef a jib, can a sailboat have multiple jib sails, jib sail materials.

The jib sail is a very important part of the sailing experience. It is a triangular stay-sail set at the front of the boat, typically held up by furling, which allows for easy retracting and maintenance.

The jib sail generally takes most of its power from the wind instead of relying on direct force from the mainsail.

With this design, it can be adjusted quickly to suit different wind conditions or speeds for optimal performance.

While some may consider it to be a difficult piece of equipment due to its many variations, when used correctly the jib sail can often give more maneuverability and speed than traditional sails.

Overall, it is an integral tool for sailing enthusiasts who appreciate its power and adaptability.

The sailboat component known as a jib has an interesting name with an interesting backstory.

Many centuries ago, sailors would use these jibs to sail around and explore the world. Those same jibs were referred to by the nickname ‘jibboom’. This stuck with generations of sailors and eventually, they began referring to the component simply and solely as the ‘jib’.

Today, a jib is commonly used on sailboats and is a key component in their design. Cruisers rely upon it for navigation purposes, while racers use it to achieve greater speeds when going upwind.

Modern technologies have allowed us to improve upon this centuries-old contraption, but its basic name – the jib – remains unchanged in popularity.

When it comes to sailing, many people wonder whether or not a jib is necessary for their experience. In short, the answer to this question depends on what type of sailing one intends to do and their level of experience with the activity.

For newcomers to the activity, it is advisable to have a jib since it will provide increased stability. This stability can be helpful in ensuring that the boat does not capsize and that complete control is maintained at all times.

A jib is a smaller foresail than a genoa, so might be preferable on a smaller boat. It is easier to handle than a larger genoa sail.

Of course, it is also possible to sail on a main sail alone. It will be harder to balance the boat, making steering harder work and a main sail isn’t always the most appropriate sail for different wind angles, but it is absolutely possible to sail without a jib or genoa.

Ultimately, the decision between needing a jib or not boils down to personal preference as well as skill level when it comes to sailing. It’s even possible to use a sailboat without sails !

Sailing with jib only is possible, although it isn’t usually the preferred way of sailing if you have a mainsail. I have to admit that Adam and I love sailing on our jib alone in the right conditions.

With some proper and well-thought-out balancing techniques, some experienced sailors argue that a vessel’s performance can be improved with jib alone. For example, sometimes the main can block the wind when sailing close to downwind, and flying the jib alone helps you pick up more speed.

Ultimately what’s important to remember here is that it can be done but that it requires good technique and a strong knowledge of how different sails work together with one another and the vessel itself in order to get optimum performance out of any yacht.

Trimming a jib sail is an essential skill for any sailing enthusiast. Knowing how to make the necessary adjustments can make a huge difference between an enjoyable day out and a frustrating one.

It’s important to understand that each boat will be slightly different, so it’s worth taking the time to familiarize yourself with your vessel before attempting to trim your sail.

Before you head out, double-check all of the halyard tension, clew and yard position, runner tension, Cunningham positions, and outhaul settings for maximum efficiency.

Once you’re out on the water and ready to get started, use your mainsail as a reference point and adjust your jib accordingly. To achieve this, start by bringing in the clew until it’s approximately parallel with your boom, then ease off on any necessary halyards while dropping the tack until you reach optimum performance.

Gauging this accurately requires practice and an understanding of wind conditions. With a little patience and practice, you’ll soon know exactly how to trim a jib sail.

Understanding the different parts of a jib will help you to understand how it works and how to get the best possible performance from it when sailing.

• Luff -This is the sail’s forward edge. The luff of the jib is attached to the forestay.
• Leech – The sail’s back edge.
• Foot – The bottom edge of the sail
• Tack – The tack is between the luff and the foot of the sail and is attached to the boat with a line that can be adjusted.
• Head – The corner at the top of the sail between the luff and the leech.
• Clew – The clew is the part of the sail attached to the fuller.

Reefing a jib is a skill practiced by sailors everywhere. It involves carefully trimming the sail of the jib, making sure you show just the right amount of sail area to ensure maximum power and speed.

Having the ability to reef your jib is also a major safety factor when out at sea. The saying goes that if you’re questioning whether or not to put a reef in, you should have already done it. If you’re wondering whether to shake a reef out, have a cup of tea.

Most boats these days have their jib sails on a furler, meaning you can simply tension the furling line to reef the sail. Then, sheets are adjusted to alter sail shape, maximizing its ability to accelerate in different wind speeds and directions.

Often you will find that reefing the sails in high winds will actually give you more speed, as it will lessen your heel angle and give additional waterline length. The more experienced you get, the easier it becomes to know the sweet spot.

As jib is the name given to any foresail that doesn’t overlap the mast it is possible to have multiple jibs on board.

The most common type of sailboat to fly two jibs at once is called a cutter rigged boat. They have two stay sails which could both be jibs. It is more common to have a larger genoa on the outer stay and a smaller jib inside to give you greater flexibility in different conditions.

You could also carry a storm jib which is usually small and made from a heavier material and is attached to one of the stays in rough weather.

These essential sails are usually made from materials that are designed to be lightweight yet durable, depending on their use.

One of the most popular materials for jib sails is polyester, usually a type of laminated Dacron cloth. This gives a good performance but with the durability that most cruisers desire. Additionally, they can be designed with multiple layers to add extra durability.

Race sailors might choose to have jib sails made from something like Kevlar, a really light weight material that won’t stretch (but will rip more easily). You won’t find them often on cruising boats due to the high cost and lower durability of this material.

Conclusion: What Is The Jib On A Sailboat?

In conclusion, a jib sail on a sailboat is a triangular sail set between the mast and the bow. It helps the boat to move through the water and provides additional power when sailing upwind. It can be used alone as an excellent downwind sail too.

Beyond providing much-needed assistance with sailing, this setup also adds some great aesthetics to any boat!

Whether you’re interested in buying one for yourself or just out exploring boats on the water, be sure to look out for what type of jib sail is being used!

Sailing's Best Hack: Sailing On The Jib Alone

Last Updated by

Capt Chris German

June 15, 2022

Sailing on the jib alone may seem unethical but is a great way to head downwind, sans main, while at the same time making it easy to switch from sail to power.

Downwind sailing can bring with it, a host of trouble. From accidental jibing to broaching,  there are a ton of things that can go wrong when sailing with a main on the downwind leg. Mix in with that the hassle of raising and lowering the main, particularly if you're single-handing, and that jib starts to look pretty good.

Usually equipped with a roller furler, a jib can be peeled out and put away with a quick yank of line. Reefing a jib is as simple as pulling out a small flake of sail or shrinking it down to virtually nothing.

Sailing on the jib alone can save time, energy and effort and if you’ve never tried it, you're missing one of sailing’s  best little sailing hacks.

Table of contents

The main is a pain

The main sail is your power house. A boat gets most of its momentum from the main; but it is also a giant pain in the rear to put up, take down, put on the sail cover, jibe, and do a whole bunch of other things.

In heavy air, the main is a terror with possible accidental jibes and overpowering events like broaching. In light air, you have just as much chance of jibing while running, but get little benefit from the main with barely enough wind to fill it.

In either scenario, heavy or light air, who is going to steer the boat if you're single-handing and have to climb up to douse the main, wrap it in sail ties and cover it with a sail cover? Even with an auto helm, that's a lot of work and a long time away from the helm.

What if you just doused the main and used the jib? Better still, what if you never put up the main in the first place?  

Unlike the main, there is no sail cover, no sail ties and you never have to worry about the accidental jibe with your jib. It sits up on the bow, can catch all kinds of wind on the downwind leg and is a breeze to douse when it’s on a roller furler.

Here’s a little scenario for you:

You’re sailing home and will come into the dock in the next half hour. You don't want to raise the main just to pull it down in 20 minutes to come into dock and you really don't want to wake your crew who have been up all night at the helm. You also don't want to start your motor because that too will wake your crew and she needs as much sleep as she can get cause she is driving home while you sleep in the back seat.

You know you will have plenty of time to fire up the motor when you get inside the breakwater, but for the last half hour while you are in open water with a great breeze at your stern. Why not take advantage of the wind by sailing? Roll out your jib.

You uncleat your roller furler line and give the starboard jib sheet a tug. The jib rolls out on your starboard side and fills with air before you even think to pull it all the way in and your boat pushes forward at 4 knots and you don't make a sound.

Twenty mins later, you spy the safe water mark of the harbor and realize that it's time to get ready to dock the boat. You preheat the motor and turn the key and smell of exhaust fills the cockpit as the boat rumbles to life.

Within a moment  your bleary eyed crew stumbles on deck and says, “Thanks for letting me sleep.I needed that.” You nod and smile, knowing that she will be eyes wide open when you are sawing logs in the back seat on the way home.

While your crew readies the fenders and dock lines, you give the roller furling line a yank and the jib tightly rolls up and you motor the vessel into your slip. You just pulled off one the greatest sailing hacks there is.

That’s really how easy it can be sailing on the jib alone. No muss no fuss, no main, no pain, just smooth sailing on the jib alone. Is it unethical? Well maybe, but it's just too damn easy not to do it.

Can I do it on the upwind leg?

The short answer to that is no. The Jib is useless alone on the upwind leg because it needs a main to work due to slot effect.

In the article,  Guide to Sail Trimming And Shape,  we discuss slot effect saying, “With a jib it (also) needs to have a nice wing shape to it, but in that case it needs to be pulled in concert with the mainsail because it enhances the flow of wind on the backside of the main. This is all under the lift principle which is mostly what is happening when you are upwind sailing.”

On the upwind leg, the jib squeezes the wind on the backside of the main and that causes the main to get more power. If the jib has no main to squeeze the wind on to, it is out of balance and carries too much wind on its back side.

That causes the boat to turn away from the wind because it has no main on the back side of the sailboat to counteract the effort to point it towards the wind. Unfortunately, sailing upwind with the jib alone will only cause you to sail in circles.

Sailing with the jib alone doesn’t work on the upwind leg and makes it  kind of unethical because there is no balance between sails when you have only the jib out. Sailing purests might scoff at you if all you ever sailed with was your  jib, but in my book, any wind is good wind and if a boat works a boat works so why not do it? The pirates did and look where it got them?

The transition from sail to power

Now I am not saying that jib sailing is gonna be the next Olympic event and there is no way it will win any races. It is a cheap sort of way of harnessing the wind on the sly and is kind of a lazy way to sail, but it works.

It’s particularly nice on days when you're not entirely committed to sailing. For example, light wind days.

Another scenario:

Say your cruising along under power and see a tiny little ripple of wind on what is otherwise a mill pond kind of day. You're not sure if the wind will fill in, or if it's gonna be an iron gennie sort of afternoon. You're sick of listening to the motor and the fumes are blowing back into the cockpit and making you nauseous.  

You peel out the jib and try it.

Initially the jib fills mostly and you think ok, lets secure the motor and breath a little easier. The motor quiets and the boat slows to a bare motion of 2 knots.

The sun beats down on the boat and it's getting hot and a silence falls over the boat as the jib flaps uselessly in the still air.  You should have kept the motor on.

If you had raised the main, your boat would  still not be moving at all and everyone would be hot from climbing all over the cabin top to raise it, and now you would have to ask them to lower it. Who wants to be that guy?

Instead, you pulled out the jib and now you can just as easily put it away. You refire the motor and head back to the dock for gin and tonics in yacht club air conditioning, a fine alternative to heat exhaustion and sunburn on a non-wind sort of day -  and you’re the hero.

I hate to say it, but I am a lazy sailor and I love sailing with the jib alone. It has its merits and there are days when it's just too hard to put up the main. I wouldn’t recommend doing it every day, and never on the upwind leg, but if the opportunity presents itself, why not take advantage of one of sailing's best little hacks. Do good, have fun, sail far and thanks for reading.
