Best Marine GPS Chartplotters Comparison Chart

BEST MARINE GPS CHARTPLOTTER (NEWEST MODELS)

This is the right place to acquaint yourself with some of the latest sailing navigation products on the market which we carefully handpicked for you. Our team has pointed out the essential features of the units as well as the possible drawbacks that you may experience with them.

1. Garmin Striker 4 GPS

The depth readings that this unit gives are also invaluable because you will know when you enter the shallow water. Additionally, some other metrics that you will be informed of are:

• Temperature
• Time of day

Another advantage of the Garmin Striker 4 is the fact that it pretty much comes with everything needed for smooth operation. There is a transducer in the set together with a power cable. You may get a 12V battery so that you can use the product without a power outlet, but this will have to be purchased separately.

On the downside, if you go outside of the USA, the map won’t be visible. You can still use the GPS and fishfinder features even outside of the US.

• The cord length is pretty good – about 10 feet.
• The unit can be easily disconnected from the mount
• If you use a 7-amp 12V battery, the Garmin Striker 4 will work for over 12 hours. This is well above the average of 9 hours.
• The chartplotter has a downscan and a transducer
• No maps of other countries are included.
• You have to go online to get the full owner’s manual -(http://static.garmin.com/pumac/STRIKER_OM_EN.pdf)

2. Hummingbird Helix 5 Chirp GPS

A little knock on the product is that it doesn’t come with a screen cover. You will have to be careful around it. However, you will be happy to find out that the chartplotter works with SD cards. Also, it’s transducer’s cable is about 20 feet long.

Getting information not only on the fish around you but also on the depth of the lake is pivotal. This product will let you know of both, even if you move at a speed of around 50 mph.

• This model will give you decent images of the bottom of the lake.
• The GPS function leaves “trails” on the map showing you where you have been.
• You get the product with everything you need to operate it. There’s the unit, the bracket to mount it, a 6-foot power cord, and the transducer.
• There is no side view scan feature on this model
• Not so many languages are included in the settings. For example, there is no Arabic.

3. Lowrance HOOK2 Fish Finder

Bear in mind that coastal maps aren’t included. If you want to add more maps, you will have to purchase a Micro SD card separately.

When it comes to the GPS chartplotter’s features, you can add various waypoints, trails and to also see the position of the boat on the chart page. If you wish to use the device on your kayak or any other boat that doesn’t have power, you have to get a 12V battery.

Needless to say, the set includes a power cord and a transducer as well. The product can be installed on a 24-foot pontoon without any issues, although many people use it mainly for smaller boats. The most significant advantage according to us, is the presence of the sidefinder function. Only the Triple Shot model has it. If you get the Split Shot one, the feature will not be there.

• The unit supports a split-screen function.
• It has a Micro SD card slot. You can add more maps to it.
• Broader sonar coverage in comparison to previous models
• The transducer in your trolling motor is not guaranteed to work with this sonar. You have to contact the manufacturer for confirmation.
• There is no screen cover included

4. Garmin Echomap Chirp 74Cv

• Operates well at high speeds
• Compact size and easy to carry
• You have to purchase and add lake maps additionally
• No batteries included
• No side view

5. Humminbird GPS G2 Fish Finder

Moreover, this unit can record at a maximum of 1500 ft depth and has 4000watts PTP power input with 2.5 inches target separation. Also, the product’s GPS function can save your tracking, and it will tell you the depth of the subsurface even when you are sailing with more than 1 or 2 mph. And since we have mention speed, this unit can read both mph and kph. But like any other additional feature, extra maps should be purchased separately. At least their installation is easy – just use the micro SD card slot which is also a tremendous addition to this unit.

• Transom mount transducer
• Helix 5 Chirp fish finder
• AutoChart Live
• 256 color display with backlit
• You have to buy the inline fuse holder
• No side view scan

6. Garmin GPSMAP 78sc Handheld GPS

You can also mark your waypoints and manually enter coordinates in case your favorite fishing spot is not shown in the preloaded maps. As for the other options that you will get with this unit, there are plenty of other charts available to be easily downloaded on your device, but you will have to buy them separately.

Nevertheless, these extra maps are exact and cover areas all over the world. But there is one thing you may not like that much – the package does not include a GPS mount or a clip so you will have to use the lanyard which comes with the unit to secure it on your boat.

• 20 hours of battery life
• High-sensitivity GPS receiver
• Waterproof by PPX7 standards
• Preloaded worldwide charts
• Cannot show the depth
• Difficult to see the screen under heavy sunlight conditions

7. Elite-12 Ti2-12-inch Fish Finder

• Touch screen and button functions
• Wireless technology
• Maps outside US/Can will have to be manually added.

8. Simrad Go7 SXR Chartplotter/Fishfinder

A Few Words About The Types That You Really Need To Know

And if you have skipped Geography classes, the latitude and longitude coordinates will not be familiar to you at all. So, here comes the pivotal role of the Chartplotter. This unit is an excellent combination of a GPS system and an optical device through which you can actually see where you are positioned on the map shown on the chart plotter’s screen.

Hence, you can no longer be lost in numbers or coordinates because they are going to be accurately plotted on your device so that you can easily read them and go sailing with confidence.

However, chartplotters come in different types, and this is perhaps what will make you feel confused when considering buying one. For this reason, our team has compiled a list with the basic models that you may come across on the market as well as their main features and characteristics. And remember that the more advanced the technology is, the bigger the price you will pay for such sailing electronics .

1. Handheld Chartplotters

This type of device for marine navigation has the option to be placed anywhere, and as their name gives it away, you can hold them in your hand. They come with internal GPS and are small in size which makes them very compact to use while sailing or doing watersports. Handheld Chartplotter has all the essential functions which will be enough for you to determine your position on the map and mark your waypoints. In addition, these units are equipped with integrated maps although not that detailed as you may wish for.

Still, all handheld chart plotters’ manufacturers offer a wide variety of lake or sea maps to be downloaded or bought separately as an add-on to your unit. And one more thing – since the screen of such products is small, you need to pick a handheld Chartplotter with very bright colors and screen protection from direct sunlight.

2. GPS Marine Chartplotters

The second type is also basically like the handhelds, but the difference is that its screen is bigger than the former’s. Therefore you will not find it very comfortable to hold it or mount it on your kayak, so such guiding navigation is more suitable for bigger boats and not intended for water sports. However, GPS Marine sailing electronics may come with so many features such as additional maps, options to save waypoints and routes, a barometric altimeter and a built-in compass. In short, this is all you need for a weekend sailing.

3. GPS Chartplotter With Built-in Fish Finder

Now, this is what every fisherman would like to have in their boats. This type of device has the same characteristics as the basic GPS Chartplotter, but there is a built-in fish finder. You will definitely like this extra since it sends sound waves into the subsurface and then turns the signal into a picture to be shown on the screen of your chart plotter. This way you will easily find the perfect fishing spot without wasting your time and your boat’s fuel. Another thing is that you can upgrade such steering navigation with a sounder when you buy an additional antenna for the weather or radar. Also, some models come with a transducer, but if this is not the case with your chosen model, you can always purchase such separately.

4. Network Chartplotters

As the name suggests, this is a high-tech navigation device designed to provide you with the most accurate information of the sea bottom as well as give you full control of your boat. Usually, network chart plotters have built-in internet connectivity so that you can use your marina’s Wi-Fi or tether it to your smartphone. This way you will get not only an accurate picture of your target place and your route, but also be alerted of possible dangers under the water. Also, the operation systems of network chart plotters are exclusively user-friendly and very advanced, so you will really like all the extras it has to offer like controlling your boat motors, water temperature feature, free Cloud services and even listening to music.

5. Network Chartplotters With Built-in Fish Finder

These types of marine navigation systems are again aimed to aid fishermen, but since it is cutting-edge technology, you will undoubtedly enjoy the 2-dimensional image of the sea bottom on the screen. This way, your fishing trips will become even more productive and satisfying.

What To Look For In A Marine Chartplotter

In this section, we are going to list some of the features that may come with your Chartplotter or be purchased separately to boost your navigation device’s performance. We have included some basic information on each one’s purpose and functions as well. This way, you will no longer hesitate what the most useful feature for you and your sailing activities is.

1. Transducer

Some marine chart plotters are sold with a transducer while others are not. But in either situation, you need to know why a transducer is so important and what type you need.

Transducers actually serve as an antenna for your boat sonar’s system. The electrical signal that comes from the sonar is turned into a high-frequency sound which is then sent into the water’s subsurface and when it reaches the bottom or any other object like rocks, for example, the signal returns. At this very moment, the transducer receives the incoming signal and turns into a frequency that can be read by the sonar. And this is how you get the image of what is under your boat.

The transducers that come with chart plotters will be efficient because you will not waste your time and money in searching for any additional devices. Also, this tool for converting electrical signals will help you when you go fishing or when sailing in unknown waters.

2. Chirp Sonar

This feature is excellent for giving you an accurate image of the sea bottom in terms of depth and resolution. And thanks to the fact that this type of sonar transmits and receives signals in more than one frequency, you can quickly tell apart big fish from smaller ones for instance.

Also, if your marine Chartplotter is equipped with Chirp sonar, then the chances of you receiving misleading information from the sea bottom are minimal. The reason for this is the ability of the sonar to tell the difference between true sonar echo and disturbances.

In addition, there are different frequency ranges for the Chirp sonar that can be exceptionally functional depending on where you sail. And this is crucial when you want to cast your anchor successfully. So, do not miss out on our best boat anchors  thorough guide along with our top picks to help you choose the right device for mooring your vessel.

· Low Chirp Frequency

Here the signal is transmitted at 25-80 kHz or 50 kHz, which means that such signal will be excellent for sailing in really deep waters – more than 196 feet.

· Medium CHIRP Frequency

When the frequency is between 80-160 kHz or 83 kHz, then you can easily find great fishing spots in shallow waters.

· High CHIRP Frequency

At high frequency like 160-800 kHz or 200 kHz, you will definitely get the highest resolution. Moreover, if your vessel is sailing fast, the high chirp frequency will be able to show you whether there is fish or other objects under the water. Also, such a frequency range is most suitable for water depths of up to 196 feet.

No matter whether you are sailing in the sea or fishing in a lake, you need to know your exact whereabouts. This is why maps are of great importance, and all chart plotters come with preloaded ones. However, the in-built maps are usually too general, and very often you will not find your preferred fishing spot there. Or, if sea adventures are your thing, then all of the places you have never been to will not be installed in your steering navigation system . But this does not mean that you cannot get the map you want, it is just that you are expected to buy anything extra from the manufacturer.

So, when picking a marine Chartplotter, make sure to get all the details about the preloaded maps and all the charts that do not come in the package.

4. Mounting Hardware

Although not a feature of the chart plotters’ electronic characteristics, positioning your device the right and safe way is vital. We advise you to check your boat’s dashboard and think how to mount the Chartplotter since some vessels ‘panels with controls are not conventional.

Also, make sure to research the material of the mounting bracket. If plastic is mainly used, then you will have to buy a new product for securing your Chartplotter as this material is not durable at all.

5. Screen Brightness Display

When choosing your perfect device for marine navigation , do not forget to check whether there is protection against direct sunlight. It is also essential to pick a product with extremely bright color options to get a clear view of the images on your sailing electronic device regardless of the weather conditions.

Marine Chartplotter Installation Tips

Here we will give you a step-by-step guide to installing a basic model navigating device .

• Choose the place where you will mount the Chartplotter and make sure it will fit. Sometimes this is a challenge, especially when you have to consider the protection of the device as well as the viewing angles.
• After deciding on the most appropriate place, drill the 4 holes for the mounting studs. You should make a hole in each corner to match the device’s chassis.
• Run the cables for the chart plotter before you actually position it.
• Then you have to reach in behind to fix the thumb nuts to secure the unit.
• Place the helm panel and after that turn on the device for testing.
• Insert the chart data card (if you have such), and your Chartplotter is ready to navigate.

Finally, do not forget to read the manufacturer’s installation guide for more specific details on your marine steering device .

Maintaining Your Marine Chartplotter

Any device needs proper care, and the same goes to chart plotters. And given the fact that you will use this device in any kind of weather conditions and in a variety of situations, you need to know how to keep it safe. So, here are some hot tips about maintaining your fishfinder .

Taking care of the visible parts is a must. And the screen is the most important here. Make sure that:

• You clean it with a soft cloth or a PC screen cleaner
• The back of the chart plotter is sealed against the pod; otherwise, the device will not be water-resistant.
• You do not use abrasive or solvent-based cleaners.

2. Software Updates

Updating your marine navigating device is essential because it can give you the latest information about the weather, currents, tides and many more. Make sure to call a technician or contact the manufacturer if any problems occur when the image is blurred on the screen, for example.

3. Replacing instruments

Sometimes you will need to make some changes to your Chartplotter device either due to upgrades or any troubleshooting features. In these situations, it is crucial to take into consideration the following tips.

• In case your display has been cracked, or your transducer is not working, and you have to replace them, remember to contact the same device’s manufacturers.
• If you cannot find a replacement for your Chartplotter model because your navigation system type is no longer in stores, then you still have some options.

A- If the part that you need is a stand-alone instrument and it is not connected to any network, then it is going to be easy as any piece can fit.

B- If the part is networked with others, then you will have to check whether your device is equipped with a standard NMEA output. Remember that your new instrument must use the same protocol to make it work but make sure you get some extra cables, just in case. Also, a data combiner will be a great idea since some NMEA protocols have a limit to the number of instruments.

Marine Chartplotter Safety Tips

Buying and installing your electronic navigation system is just the beginning of your sea adventures. But if you are not aware of the possible dangers or do not know how to work with your Chartplotter, then any voyage will turn into a nightmare. This is the reason why we have prepared some essential tips to ensure safe sailing.

• Navigation systems are essential, but they are made to assist you, so do not rely only on your Chartplotter. You really need to have some basic navigation knowledge and know your boat.
• If you are going to use a map that is on an SD card, make sure that the map is up-to-date. This way you will have the latest information about all the possible dangers that you may come across.
• It is vital to study and understand all the symbols that you will see on your device’s screen.
• When plotting your course remember to check what is standing between you and your destination because your Chartplotter will show you the shortest way but not the hazards you may come across.
• Make sure you plan your route carefully and understand where exactly you are going. You can get an excellent helper when looking at what is in front of your vessel in the far distance if you have binoculars. So, do not forget to check out our best marine binoculars  top picks and extensive buying guide to aid your navigation.
• Some models for marine sailing navigation will let you zoom in and out. Although this is a helpful feature, you really need to use the largest scale zoom possible so that no functions are lost during this option.

This is the end of our guide but surely the beginning of your safe sailing adventures.

The Best Boat GPS: Buying Guide

What is a marine gps.

A marine GPS is an essential marine navigation tool—but what does it actually do? As you can see from the list above, there are GPS emergency radios, fish finders, chart plotters, and more. Do all GPS devices do the same things, or do some serve different purposes?

First, let’s look at what a boat GPS actually does. It’s a global positioning system that can be used on bodies of water and over open ocean. They can pinpoint your exact location and give you your bearings. All GPS devices will at least do this.

Emergency GPS Systems

Some have emergency tools that allow you to call in help if you find yourself in distress. Others have live weather updates, live marine communication updates from other vessels, and other emergency functions. Many of these are handheld, battery-operated devices that can be used if your main power source is down.

GPS Fish Finders

Another popular kind of GPS system is a fish finder. These devices use transducer sonar to map the lake or sea bed, and track fish. The burst of scanning sonar bounces off of objects in the water, and the fish finder’s sensors convert the results into imagery that fisherman can read to determine the location of fish. These fish finders are very useful for fishing trips .

GPS Chartplotters

A GPS chartplotter or (chart plotter) is primarily a mapping and navigation tool. Like automotive satellite navigation products, these boat GPS trackers keep an eye on your location and plot your position on a map. They continuously monitor your exact position, your speed and heading, and plot your location in relation to land mass and other important markers or way points. They can also be used to store routes that can be loaded when you need them.

Important Features To Look For

Once you’ve got an idea of what type of GPS device you’re looking for, you can start focusing in on what other important features that you need. Here are some things to consider when you’re searching for a GPS system for your boat.

Maps are arguably one of the most important features of any GPS unit. However, not all marine GPS navigator devices come with maps installed. Some require your charts to be bought separately and uploaded to the device, while others have them pre-installed. There are some devices that don’t have any maps at all, simply relaying your co-ordinates which you can then note on a good old-fashioned sea chart instead.

Even if a device is pre-loaded with maps, make sure to check what areas they cover and what kind of water. Not all devices will have freshwater charts. Most will only have charts for your country.

Chart plotters and fish finders are great, but emergency tools are some of the most useful to have installed on your GPS marine navigation devices. Emergency calling and distress signaling is incredibly useful, particularly if you’re heading out to sea. Even if you’re staying close to the shore, accidents can happen, and having a device that can for help is a wise idea.

It’s easy to prioritize chart plotting as an essential feature, and it is an important feature, but safety should be just as important too. Some GPS systems have wi-fi that link up with marine GPS app programs that can be set up for emergencies.

Other cool features include an electric compass, a barometer, and weather updates. Keep an eye out for these when you’re shopping.

Portability

Do you need a battery-operated handheld device, or would you prefer a hard-wired, permanent interface? If you use multiple small-size vessels, it might be more economical to buy something portable that you can use on different boats from one day to the next. These devices usually don’t offer the same kind of features that more permanent-mounted devices do.  However, if you primarily use one boat, it might be best to invest in a permanent GPS system. It all depends on your needs.

If you opt for a handheld marine GPS navigator, then you should be mindful of the battery life. Some have standby times of over 20 hours, while others have quite limited 3-hour operational times. Naturally, what battery life you need depends on how long you’re on the water.

Some devices rely on your boat’s battery and motor to operate. These devices are more reliable but they do have some quirks to them. Always make sure that you read the voltage and motor type required to power one of these. Some trolling motors aren’t up to it, while bigger batteries can be overkill.

Even if you have a system that’s hooked up to your boat’s motor, it’s always wise to carry a battery-operated back-up, just in case of power failure.

A marine GPS unit should be waterproof. That should go without saying. However, there are different kinds of “waterproof” definitions. Here’s the official scale of waterproofing , and what level of protection each designation offers:

Another key feature to keep in mind is the user interface. Touchscreen devices usually feature nice wide screens with crystal clear displays. They can display a lot of useful information all at once. Unfortunately, touch screen technology can be tricky to operate in wet conditions.

Keypad controlled devices are simple to use and work well in wet conditions. Unfortunately, the actual control systems can be a pain to use, with laborious menus. More often than not, these keypad devices have smaller screens too.

The difference in price between the two types could help make that decision for you though.

The price is arguably the most important factor to take into consideration when buying a marine GPS tool. Good quality equipment doesn’t have to be expensive, but you should be wary of a product’s limitations. If you go cheap, don’t expect it to have all of the top features that you’d hope for. It will be basic, but it should do the trick.

It’s also important that you don’t fall for the whole “it’s the most expensive so it should be the best” trick. Throwing money at a device isn’t the right way to go. It’s wise to make sure that you’re investing in a product that you actually want, will actually use, and suits your needs. There’s no point spending thousands on an ocean-ready GPS that’s designed for transatlantic journeys when you’re only fishing around your local lake in a pontoon boat.

Lastly, always read the reviews. Don’t just take the word of marine GPS review sites. Make sure you check with other sources, writers, journalists, and forums before hitting the buy button. Also, if you’re buying from an e-commerce site like Amazon, then read the FAQs and reviews there too.

A certain product may ship without maps loaded into it, or with charts that don’t cover your area. The review section is the best place to mine for answers to those smaller, and often-overlooked questions.

The Best Boat GPS: In Summary

For sailors looking for a budget GPS option, or for those looking for an excellent backup system, then we recommend the Cobra COB-MR. It can easily calculate your position, runs off of battery power, and has an emergency alert system. It’s not the most advanced system, since it doesn’t boast any live charts, fancy imagery, or fish finding technology, but it is cheap, easy to operate, and very practical.

If you have a bigger budget, then the most impressive premium product on the market would have to be the Garmin Echomap Plus 94sv. A Gamin marine GPS won’t let you down. Ever! It’s an advanced fish finding tool with sonar technology, contouring imagery, and more. It also features a highly-sensitive GPS system, with detailed maps and amazing connectivity. Since it’s compatible with other Garmin products, it’s a very useful tool to have in your satellite-navigation arsenal.

For boaters who are just looking for a decent product that ticks all of the right boxes, won’t break the bank, and won’t fall apart easily, then we’d recommend the Humminbird Helix 5 G2. Primarily developed as a fish finder, the Helix 5 does everything a fish finder can, but it also has an advanced GPS system with an easy to use chart plotting tool. It scores big in terms of value for money, and that’s why we’ve named it as our favorite over all.

Thanks for the excellent reviews! It can be hard to narrow down the product you are looking for. Too many times have I been in a hurry and purchased the first product that seemed to fit what I wanted. These Boat GPS systems seem to be more tailored to fishing. Are there different Security systems based on boat size or are they all in 1? Would a yacht require different boat security than a smaller fishing boat or does it come down to features? Thanks again!

Mark & Alpha Remaley on January 18, 2021

With so many choices I am confused. Our pontoon boat is in a relatively small (less than 1 aq. mi.) inland lake and I would like a really good depth profiler so I can see details on the bottom (for scuba-diving & curiosity), and a fish-finder. Those are the two things I really care about, and navigation in a small land-locked lake isn’t really a major concern, so in your opinion what unit would be the best for the limited conditions I have outlined? Thanks for any help on this.

Best Marine GPS Chartplotters for Sailing of 2024

The days when sailors navigated with compass and sextant are long gone: modern marine electronics provide us with a range of information that explorers of the past couldn’t begin to imagine. Larger vessels are outfitted with networks integrating GPS, charts, radar, sonar, wind sensors, communication, emergency alerts and much more. Nowadays, even handheld units can handle any navigational problem short of plotting a course for Margaritaville or the Fountain of Youth. All of that capacity does create some confusion, and the range of options on the market can be daunting. We’ve simplified the choices with this guide to the best marine GPS chartplotters.

We’ve tried to keep the descriptions simple, but if CHIRP, WAAS, and NMEA 2000 aren’t part of your day to day vocabulary, you may want to skip to the bottom of the article and read the explanations first!

Comparison Table - Best GPS Chartplotters for Sailing

Reviews - Best Sailing GPS Chartplotters

Garmin gps 73.

• Type : Handheld
• Display : 2.6” B&W
• Sonar Transducer : Not Included
• Sailing Software : Garmin Sail Assist
• Networking : NMEA 0183, Bluetooth, USB
• Runs 18 hrs. On 2 AA Batteries
• High-Sensitivity Receiver Locks Satellites In Any Conditions

BEST HANDHELD

This one is not actually a chartplotter at all. We’re including it in the review because it has a solid array of sailing-specific features that make it a great choice for boats that are too small to host a console-mounted system or as a backup device for use if a larger vessel’s primary system fails or if you’re forced to abandon ship. 

The Garmin 73 is handheld, convenient, and easy to use. It doesn’t support the whole range of features included in Garmin’s SailAssist software, but it will give you tack assistance, virtual starting and heading lines, countdown timers, and arrival times based on sailing constraints. That’s a very tidy bundle in a very small package.

Garmin has a great deal of experience with hand-held marine devices, and the GPS73 reflects this. The back-lit buttons and high-contrast display are easy to use in very bright or limited light,  there’s a useful range of marine data built in, and you can store 1000 waypoints and 100 tracks for repeat navigation. Don’t expect the GPS73 to duplicate the functions of a full-sized chartplotter with an array of sensor inputs, but it does what it does well and reliably, and it is designed with wind-driven boaters in mind.

B&G Vulcan 7

• Type : Console Mounted
• Display : 7” Color
• Sailing Software : B&G SailSteer
• Networking : NMEA 2000
• Compatible With Forwardscan Sonar and B&G Autopilots
• Instrument Data Display
• Multiple Language Packs

BEST SAILING-SPECIFIC VALUE

B&G is the acknowledged industry leader in sailing-specific marine electronics, and was the first to bring a full range of sailing support features to a consumer-oriented electronics package. The Vulcan 7 continues this tradition, wrapping an impressive array of sailing-specific features into a compact, durable, and affordable chartplotter. 

The screen is bright and versatile, displaying all of your sailing and wind information with layline and tacking options overlaid on up-to-date navigational charts. It also offers race support features that get you to the start line at speed with the right heading at the right time. The system integrates with numerous accessories, notably B&G’s highly regarded autopilot systems, to give you a level of control you’d expect from a much more expensive system.

This one is all about sailing, so don’t expect a fish finder or other features more applicable to the motorized set. If you’re looking to upgrade your sailing game without spending a fortune, though, you won’t find a better choice than the Vulcan 7.

Raymarine Axiom 7

• Sonar Transducer : Included
• Sailing Software : Lighthouse 3
• Includes Surface And Trunnion Mounting Kits
• Quad Core Processor For Blazing Speed
• Coastal Coverage For USA and Canada Plus Over 20,000 Inland Waterways

BEST VERSATILE CHARTPLOTTER WITH THE MOST COVERAGE

Raymarine makes a wide range of multifunction chartplotters, from the entry-level Axion range through the Axiom Pro and elite-level Axiom XL range. All are powered by Raymarime’s Lighthouse 3 software and offer full compatibility with Raymarine’s exceptionally large range of sensors and input devices. Raymarine also offers extensive chart coverage straight out of the box: both US and Canadian coasts along with 20,000 lakes, rivers, and other inland waterways.

The Axiom 7 may not be as “sail-specific” as the B&G Vulcan 7, but that also leaves it arguably more versatile. For example, the Axiom 7 integrates a robust fish finder capability, a useful feature if you like to mix some fishing with your sailing.  It also includes the Raymarine CPT-100DVS transom-mounted sonar transducer, so if you want a minimalist package you can just add a wind sensor and go! If you want to add more, you won’t be held back: Raymarine can provide Quantum radar, CHIRP Sonar, FLIR thermal cameras, audio integration, instruments, cameras, and the Evolution autopilot. This unit provides most of the features that distinguish Raymarine’s higher-end models, at a budget friendly price point!

Garmin GPSMap 8612XSV

• Display : 12” Color
• CHIRP : Yes
• SmartMode Station Controls For One-Touch Information Access
• Superior Clarity And Sunlight Readability, Even With Polarized Sunglasses
• Preloaded US Coastal And Lake Maps

BEST HIGH PERFORMANCE CHARTPLOTTER

Garmin delivers a serious high-performance marine electronics hub with the 8612xsv. You get a full HD 12” display with wide viewing angles, great clarity, and full sunlight readability, pre-loaded with full US coastal and lake charts and offering full connectivity with a huge range of sensor inputs, including Garmin’s Panoptic LiveScope live scanning sonar, which gives one of the best underwater views on the market today. 

Garmin’s SailAssist feature provides the full spectrum of sail-specific information and pre-race guidance. You’ll have true and apparent wind angle, set and drift, true and apparent wind speed, and much more at your fingertips! Pair those features with Garmin’s ActiveCaptain app and link your boat seamlessly to your mobile device. If you’re a serious sailor and you’ve decided to commit to Garmin as your electronic systems provider, the 8612xvs is a natural starting point!

THINGS TO CONSIDER WHEN BUYING A MARINE GPS CHARTPLOTTER

Let’s start with the basics. A GPS gives you coordinates, a Chartplotter gives you a visual position on a chart. All Chartplotters are GPS-based, but not all GPS units will plot charts! 

Chartplotters come preloaded with a range of charts, but if you sail in exotic areas, you may need to purchase additional charts. Major manufacturers supply their sail-oriented chartplotters with sailing-specific software packages that give you access to laylines, tacking points, wind trends, estimated arrival times based on speed and routes, and much more. 

Remember that your chartplotter is designed to process inputs from multiple sensors and will not be fully functional without these inputs. At a minimum this will mean a sonar transducer (included with some chartplotters) and a wind sensor, but there are dozens of other options. 

Most manufacturers recommend using their own instruments with their chartplotters, so your choice involves buying into a system , not just buying a chartplotter. Be sure to look at the range of available input devices and asses any input devices you may already own before selecting a chartplotter!

IT’S A SYSTEM

You’ve probably noticed this already, but when you choose a chartplotter, you’re choosing much more than just a chartplotter. The chartplotter is a hub linking a range of sensor inputs and communication devices. 

When you select a chartplotter you’re committing yourself to a range of other devices that will link to it, so before you buy, you’ll want to look closely not just at the chartplotter but also at the range of input devices you’ll be connecting to it. 

Fortunately all three of the major manufacturers of chartplotters offer comprehensive ranges of input devices, so you’ll have plenty of choice no matter which unit you select! If you already own wind, sonar, or radar equipment, your choice of chartplotters is likely to be directed by compatibility with your existing equipment, so be sure to take that into consideration. 

Many chartplotters are compatible with third-party instruments, but you’ll want to be sure. Your electronics are a bit like your crew: sailing is easier when they get along!

SOFTWARE MATTERS

B&G, Garmin, and Raymarine all offer software packages designed specifically for sailing. All of them offer a range of features designed for both cruising and racing, including layline plots that put a 21st-century twist on the eternal challenge of sailing efficiently to windward. 

All three major software systems are updated regularly and all provide similar basic functions. Cruising World offers a detailed discussion of choosing a chartplotter , but your choice is likely to be affected by personal preferences, and for most of us any of the three are likely to serve well. Certainly any of them will be a quantum leap forward from what sailors had available even a decade ago!

West Marine offers this detailed guide to selecting networked marine electronics . Practical Boat Owner offers a field test of the three major sailing assist programs ; it’s from 2015 and does not cover the latest upgrades, but gives a solid grounding on the approaches taken by the major manufacturers.

SPECS AND FEATURES EXPLAINED

NMEA is the National Marine Electronics Association. The group brought out the NMEA 0183 protocol in 1983 and introduced NMEA 2000 in 2000. These protocols enable all of a boat’s electronics to communicate with each other in a common language. NMEA 2000 is much faster, can handle much more data, and has better reliability and data sharing functions. Even NMEA 2000 is too slow to accommodate the complex images and data sets used modern equipment, so most manufacturers add ethernet protocols, which are often proprietary. There’s a more detailed explanation of NMEA here .

WAAS stands for Wide Area Augmentation System, a satellite-based augmentation system available in Canada, the US and some other North American territories. WAAS systems give faster and more accurate readings than basic GPS can provide.

CHIRP stands for Compressed High-Intensity Radiated Pulse. It’s a military sonar technology that has found its way into civilian use. The short story is that CHIRP sonar has a much greater ability to render accurate readings on the subsurface environment than conventional sonar. If you’d like the long story, West Marine tells you all about how CHIRP was developed here . You will need a CHIRP-equipped sonar transducer to exploit this capacity.

Laylines are the courses linking your tacking points, the routes you have to sail to make the best time headed upwind. Sail-specific chartplotters will display your layline options over chart data, allowing you to assess safety, speed, and ETA on different courses. They’ll also continually reassess your options as conditions change.

COMPATIBLE DEVICES

Your chartplotter is the hub of a network, and its functionality depends on the information you feed into it. Here are a few of the devices you’ll be able to link to your chartplotter.

Wind Sensors read the velocity and direction of the wind and feed this data into your chartplotter continuously. A wind sensor is a critical part of any sailing-specific marine electronics system.

Sonar Transducers look down or forward, and most boats will use both. Your chartplotter uses the sonar inputs to give you a picture of the underwater environment, which allows you to avoid reefs, shoals, and underwater obstacles. Many sonar units also have fish finding capabilities and most provide depth, speed, and water temperature data.

Radar Antennae give you a 360 degree picture of surface traffic and potential obstacles.

Cameras are typically installed in multiple locations around your boat and provide invaluable assistance for docking and other close maneuvering situations.

Autopilots link your boat’s steering system directly to your electronics net and allow both fully automated control and remote control from locations other than the helm.

Best boat GPS: 6 handheld options for navigation at sea

We take a look at 6 of the best boat GPS options available right now, from handheld devices to tablet apps

‘Lost at Sea’ might be a great name for a video game, but in real life the prospect of losing one’s bearings on the ocean can be pretty scary indeed. Chartplotters can – and sometimes do – fail, (it’s happened to this writer), leaving you alone with a compass and, if you’ve prepared, a set of charts to guide you to a safe haven – assuming you know, or can remember, how to navigate manually, that is…

And that, in a nutshell, is why many mariners today choose not to leave port without a backup or secondary system aboard. Happily, reserve navigation aids no longer need to be big to be beautiful as now there’s a range of powerful pocket sized devices available which put GPS technology in the palm of your hand – literally.

What’s more, these devices come in a variety of forms and formats, such as purpose-built handheld boat GPS units, GPS-equipped VHF radios and smartphone/tablet-based app setups. Incidentally, just a note on those phones and tablets: If you’re planning to use one as your primary navigation tool, do bear in mind battery time is sure to be compromised by any power-hungry application.

While handheld GPS systems are intended more to complement chartplotters rather than replace them, there are certain tasks where they leave fixed units standing. Consider, for example, overnighting at anchor. If the boat’s chartplotter is helm-mounted there’s a good chance the cabins will be out of earshot of its anchor-drag alarm.

Recommended videos for you

A handheld, however, can join you at bedtime and, should the need arise, will disturb your slumber with an alarm that will send you dashing up to the deck at the double to see what’s going on. And that alone could be a factor to persuade many boaters to consider investing in a handheld GPS system. Here’s our selection of six of the best boat GPS systems on offer today.

Garmin GPSMAP 86i

Specifications: Screen size – 3 inches, battery life – 200 hours, adjustable GPS filter

Reasons to buy: State-of-the-art, IPX7 waterproof rating, doubles up as a satellite phone

Reasons to avoid: Premium price, subscription required for satellite feature

Garmin dominates the purpose-built handheld boat GPS market and its GPSMAP 86i unit very much represents the state-of-the-art. Bristling with features, including a 3″ display which is bright enough to be readable in sunlight, the 86i has an IPX7 rating meaning it can withstand exposure to 1 metre of water for up to 30 minutes.

This boat GPS unit supports Garmin’s BlueChart g3 charts and is capable of streaming boat data from compatible plotters and instruments to place important information in your hand no matter where on the boat you happen to be. The 86i also doubles up as a satellite phone via the inReach network, for which a separate subscription is required.

Icom IC-M94DE handheld marine radio

Specifications: 1 Lithium Ion battery required, VHF tuner technology, noise cancellation

Reasons to buy: Full DSC functionality, built-in AIS receiver

Reasons to avoid: Limited navigation capabilities

Icom’s IC-M94DE VHF radio puts power in your hand in a number of ways. For in addition to GPS, it has full DSC functionality and is the world’s first marine handheld VHF to incorporate a built-in AIS receiver .

The GPS part of the package allows the user to store up to 50 waypoints. While the unit’s navigation capabilities are limited, what the M94DE can do is provide a much needed confidence boost for anyone who finds themselves at sea without an alternative nav system.

That’s because the radio’s navigation function guides the user to the selected waypoint and provides a reassuring beep once it has been reached, thereby confirming the boat’s position at sea.

Garmin GPSMAP 78

With its bright colour screen and IXP7 waterproof rating, Garmin’s GPSMAP 78 is a great handheld boat GPS choice. Ruggedly constructed with moulded rubber side grips, the unit feels good in the hand.

That said, should you manage to drop it in the briny, fear not – it floats. The GPSMAP 78 has a sensitive WAAS-enabled GPS receiver which locates its position quickly and efficiently once switched on.

It’s supplied with a worldwide basemap which can be added to by simply plugging in a pre-loaded Garmin BlueChart g2 map. And when you’ve finished having fun on the water, the boat GPS unit connects to your PC and the internet for a detailed analysis of the day’s action.

Reasons to buy: Rugged construction, IXP7 Waterproofing, Can plug into PC for statistics

Reasons to avoid: Additional maps are costly

Specifications: Battery life – 20 hours, barometric altimeter, 2 AA batteries required (included)

Standard Horizon HX890E VHF handheld marine radio

Similar in principle to the Icom M94DE, but costing considerably less (due to no AIS receiver) Standard Horizon’s GPS-equipped HX890DE VHF radio is capable of storing up to 250 waypoints.

Another factor well worth bearing in mind is that this radio does routes. Up to 30 waypoints can be tagged to create a passage, which can then be followed automatically or manually.

Setting all of this up can be somewhat burdensome, especially given the screen size is just 1.7″ square, but once programmed the routing functionality of the HX890E could well make the difference between a relaxed or stressful journey.

Reasons to buy: Up to 250 waypoints, has ability to set up routes

Reasons to avoid: Small screen, hard to set-up

Specifications: 66 channels, 1 battery required, water activated strobe light

Garmin GPS 73

The Garmin GPS 73 is an easy-to-use handheld navigator. The unit can mark and store up to 1,000 waypoints and 100 tracks, making return navigation simple.

It also features SailAssist, which is designed to help the user sail more efficiently with a heading line and tack assist, which essentially lets you know when to tack.

Other in-built features include sunrise/sunset, estimated time of arrival and various marine data. The relatively low price point reflects the fact that the GPS 73 boat GPS comes with a monochromatic display. That said, the screen is high contrast and can be read in all lighting conditions. There’s also a built-in back light for operation after dark.

Reasons to buy: Ease of us, great price, SailAssist

Reasons to avoid: Small screen without colour

Specifications: 18 hours battery life, GPS 73, nautical map type

Navionics Boating App

Navionics is a Garmin brand, so the charts used by its Boating Marine and Lakes app will look familiar to existing Garmin plotter users. Compatible with both Android and Apple devices, this popular boating app can be downloaded from Google Play or the App Store .

Once installed, maps are downloaded and stored on your device, allowing offline access at all times. As you would expect from anything to do with Garmin, the app has a multitude of features, including tracks, routing, dock-to-dock autorouting, tides and weather information and SonarChart, which provides high definition bathymetric mapping.

What’s more, Navionics’ charts are updated up to 5,000 times a day and the system embraces community edits to ensure valuable local information is kept up-to-date and relevant at all times.

Reasons to buy:  Compatible with Android and Apple, Garmin style features, updated 5,000 times a day

iPad navigation apps tested: Pip Hare reviews 7 chartplotting apps

• Pip Hare and Matthew Sheahan
• February 9, 2017

It is now commonplace to see iPads and other tablets being used for navigation, but there is still quite a difference between the best and worst apps you can download. Pip Hare tests and compares seven popular apps for ipad and android.

The development of navigation apps has now advanced to the stage where tablets are being used regularly by many sailors as a primary means of navigation on board. With the recent integration of wi-fi NMEA data to the mix, tablet navigation systems have found a permanent place in our arsenal of instruments.

I have selected seven of the best boating apps specifically focussing on new updates and innovative developments, but also with my eye on what our basic requirements for a good navigational app should be. Tests were carried out inshore, offshore, creek hopping, racing and just sitting at home on my sofa using an iPad 2 and an ASUS model P023 running Android 5.0.2.

Top rated iPad navigation apps – read individual reviews below

• Navionics and Navionics+ are a great duo – best on test.
• iNavX is good enough to replace on on-deck chartplotter .
• MaxSea TimeZero is brilliant if you want to use raster charts.
• Transas iSailor does everything, but it all costs extra.
• SeaNav UK & Ireland offers a unique ‘augmented reality’ view using Internet AIS.
• Garmin BlueChart Mobile good for planning, but only shares with Garmin hardware.
• iBoating is surprisingly versatile, but was the least expensive on test – and it showed.

The perfect iPad navigation app doesn’t yet exist but…

Having spent six weeks living and breathing these apps, I have come to the conclusion that the perfect one does not exist, but some are getting pretty close. The well-developed user interfaces that app-based products provide are far superior to those found on most chartplotters and now, with NMEA integration, the all-important GPS fix comes from an external feed overcoming any accuracy concerns around using the GPS receiver built in to the tablet.

To make the most of your chosen software, pick features that are relevant to your style of sailing. Think about what information you want displayed for easy situational awareness and make sure you spend time customising your display to show only what you need and, ideally, nothing more.

Crowd-sourced data

Crowd sourcing information has enabled the boating community to share local knowledge and update navigational features in real-time. Most apps now incorporate this in some way. A few apps are offering sonar mapping but Navionics also gives free access to its HD bathymetry Sonar Chart. This extra chart reveals more contours derived from a large database of sonar logs, which in many areas could provide more accurate charting than UKHO data.

Other crowd-sourced information includes the community edits, and the ‘Active Captain’ network, which is like an online almanac. If using this type of information for navigation check the date of the edit and treat new position info cautiously.

Top tips for setting up and using your iPad navigation device

Ports of refuge.

Before setting off on longer passages ensure that you have downloaded the charts for any ports of refuge along the way and that your current package covers countries where you may conceivably need to make landfall.

Satellite image layers

Use satellite image layers, if available, to identify landmarks when approaching a new destination.

Check units: Lat and Long

Check your units when setting up an app. To help with easy communication of waypoints between charts, plotters and tablets ensure your position is reported in degrees, minutes and decimals. Many apps only use degrees and decimals to report positions, which could be confusing, particularly in an emergency situation.

Range rings

Set up range rings to use as clearing zones on navigational hazards, or even to indicate the three-boat-length zone around a mark when racing.

Velocity vector

The velocity vector shows you where you will end up after a specified amount of time. Set the value of this vector to one hour for help in predicting tidal offsets.

How to choose the right electronics for your sailboat

Equipping your sailboat with the right electronics is crucial for a safe and enjoyable sailing adventure. This comprehensive guide will help you choose the best options for your specific needs.

How to Choose the Right Electronics for Your Sailboat

Embarking on a sailing adventure with your family is an exciting and fulfilling experience. However, to ensure a safe and enjoyable journey, it’s essential to equip your sailboat with the right electronics. In this comprehensive guide, we will discuss the various types of electronics you may need for your sailboat, their functions, and how to choose the best options for your specific needs.

Navigating the open sea can be challenging, especially for those new to sailing. Modern technology has made it easier than ever to plot your course and stay on track. Here are some essential navigation electronics to consider for your sailboat:

GPS Chartplotter

A GPS chartplotter is a must-have for any sailboat. This device combines GPS data with electronic charts to display your boat’s position on a digital map. It helps you plan your route, monitor your progress, and avoid potential hazards such as shallow waters or submerged rocks.

When choosing a GPS chartplotter, consider the following factors:

• Screen size and resolution : A larger screen with high resolution will make it easier to read charts and navigate, especially in bright sunlight.
• Touchscreen vs. buttons : Touchscreen chartplotters are more intuitive and user-friendly, but buttons can be more reliable in wet conditions.
• Built-in vs. external GPS antenna : Built-in antennas are more convenient, but external antennas may provide better reception in some situations.
• Expandability : Some chartplotters can be connected to other devices, such as radar or AIS systems, for additional functionality.

An autopilot system can be a valuable addition to your sailboat, allowing you to maintain a steady course without constantly adjusting the helm. This can be particularly useful during long passages or when sailing in challenging conditions.

There are two main types of autopilot systems:

• Wheel or tiller pilots : These are simpler and more affordable systems that attach directly to your boat’s wheel or tiller. They are suitable for smaller boats and less demanding conditions.
• Below-deck autopilots : These systems are more powerful and reliable, with a separate control unit and drive unit installed below deck. They are suitable for larger boats and more challenging conditions.

When choosing an autopilot system, consider factors such as your boat’s size, the type of sailing you plan to do, and your budget.

Radar can be a valuable tool for navigating in low visibility conditions, such as fog or heavy rain. It uses radio waves to detect objects, such as other boats, buoys, or land, and displays their position on a screen.

When choosing a radar system, consider the following factors:

• Power output : Higher power output will provide better range and resolution, but may also consume more energy.
• Antenna size : Larger antennas will provide better resolution and range, but may be more challenging to install and require more space.
• Display options : Some radar systems can be integrated with your chartplotter, while others have a separate display.

Staying connected while at sea is essential for both safety and convenience. Here are some communication devices to consider for your sailboat:

A VHF radio is a crucial piece of equipment for any sailboat, allowing you to communicate with other boats, marinas, and emergency services. It is also required by law in many countries.

When choosing a VHF radio, consider the following factors:

• Fixed vs. handheld : Fixed VHF radios are more powerful and reliable, but handheld radios can be useful for dinghy trips or as a backup.
• DSC capability : Digital Selective Calling (DSC) allows you to send a distress signal with your boat’s position at the push of a button. This feature is highly recommended for safety reasons.
• AIS integration : Some VHF radios can be connected to an Automatic Identification System (AIS), which displays information about nearby boats on your chartplotter.

Satellite Phone

A satellite phone can be a valuable addition to your sailboat, allowing you to make calls and send messages from anywhere in the world. This can be particularly useful for emergencies or when sailing in remote areas.

When choosing a satellite phone, consider factors such as coverage, call quality, and data capabilities. Keep in mind that satellite phone service requires a subscription, which can be expensive.

Keeping an eye on the weather is essential for safe and enjoyable sailing. Here are some weather monitoring devices to consider for your sailboat:

Weather Station

A weather station can provide valuable information about the local conditions, such as wind speed, wind direction, temperature, and barometric pressure. This data can help you make informed decisions about your sailing plans and anticipate changes in the weather.

When choosing a weather station, consider factors such as accuracy, ease of installation, and compatibility with other devices, such as your chartplotter.

Weather Receiver

A weather receiver allows you to receive weather forecasts and alerts from official sources, such as the National Oceanic and Atmospheric Administration (NOAA) in the United States. This can be particularly useful when sailing in unfamiliar waters or during severe weather events.

When choosing a weather receiver, consider factors such as coverage, reception quality, and ease of use.

In addition to navigation and communication devices, there are several electronic safety devices that can enhance your sailboat’s safety:

An Automatic Identification System (AIS) is a valuable safety tool that allows you to see and be seen by other boats. It transmits and receives information about your boat’s position, speed, and course, as well as other nearby vessels, helping you avoid collisions and navigate crowded waters.

When choosing an AIS system, consider the following factors:

• Class A vs. Class B : Class A AIS systems are more powerful and feature-rich, but are also more expensive and typically used on commercial vessels. Class B AIS systems are more affordable and suitable for most recreational sailboats.
• Transponder vs. receiver : A transponder both transmits and receives AIS data, while a receiver only receives data. A transponder is recommended for enhanced safety and visibility.

An Emergency Position Indicating Radio Beacon (EPIRB) is a critical piece of safety equipment that can help rescue teams locate your boat in the event of an emergency. When activated, it sends a distress signal with your boat’s position to search and rescue services via satellite.

When choosing an EPIRB, consider factors such as battery life, ease of activation, and compatibility with the international Cospas-Sarsat system.

While not essential for safety or navigation, entertainment and connectivity devices can make your sailing experience more enjoyable and comfortable:

Marine Stereo

A marine stereo can provide music and entertainment while you’re sailing, helping to create a pleasant atmosphere on board. When choosing a marine stereo, consider factors such as sound quality, durability, and compatibility with your preferred music sources (e.g., Bluetooth, USB, or satellite radio).

Wi-Fi Booster

A Wi-Fi booster can help you stay connected to the internet while at sea, allowing you to access weather forecasts, communicate with friends and family, and stream entertainment. When choosing a Wi-Fi booster, consider factors such as range, compatibility with your devices, and ease of installation.

All of these electronic devices require power, so it’s essential to have a reliable and efficient power management system on your sailboat. This may include:

• Batteries : Choose high-quality marine batteries with sufficient capacity to power your electronics.
• Charging system : Ensure your boat’s alternator and/or solar panels can keep your batteries charged.
• Inverter : An inverter converts your boat’s DC power to AC power, allowing you to use household appliances and charge devices.

Equipping your sailboat with the right electronics is essential for a safe and enjoyable sailing adventure. By considering your specific needs and preferences, you can choose the best navigation, communication, weather monitoring, safety, entertainment, and power management devices for your boat. Happy sailing!

Best Marine and Boating Navigation Apps

Table of Contents

Last Updated on May 19, 2024 by Boatsetter Team

For almost everything you do today, there’s an app that will support, enhance or complement that activity. Recreational boating is no exception, and there are dozens of boating apps to help you enjoy time on the water.

Arguably, marine navigation apps are some of the most common—and the most useful—available to boaters today, with a range of options to suit different needs. Some boat GPS apps, for example, utilize NOAA raster charts, which are essentially scanned paper charts incorporated into their systems. Some apps offer vector charts, providing electronic charts that allow for scrolling and zooming in for enhanced detail.

The convenience of downloading these apps to your iPhone, Android, or tablet enables you to have them readily available regardless of the boat you’re on,  significantly enhancing your navigational capabilities.

Best marine navigation apps ( with GPS )

These are our top recommendations for boating apps that are great for marine navigation and offer GPS. Most of the apps are free to try.

1. Navionics

A perennial favorite is Navionics because it’s easy to use and comprehensive in scope. Navionics mimics a standard chartplotter experience and in some cases can connect to an onboard plotter via WiFi. Creating waypoints and routes, measuring distances and understanding depth contours and aids to navigation is pretty straight forward with this app.

Once downloaded, the charts stay on your device and can be used offline which is great when you’re cruising in areas with little coverage. Bonus functionality includes weather and tide information and dock-to-dock routing that helps you set a viable course based on your vessel’s parameters like draft.

• Price: Two-week free trial, then subscriptions starting at $14.99
• Click here to learn more and download.
• Get the app from Google Play Store or iOS store

Easy to confuse with Navionics (especially when downloading the app), iNavX is a whole different animal. There’s a $5 charge to download the app, and then you can download NOAA raster charts for free and vector charts (powered by Navionics and C-MAP) for a fee.

Beyond navigation, details on marinas, fuel docks and other facilities are also available. Weather data overlays and additional features like engine data and AIS collision avoidance information can also be viewed, but the app can get technical in a hurry and may take longer to learn.

• Price: $4.99, plus an annual subscription

C-MAP is the primary other choice besides Navionics for the underlying charting information that many apps use with their own user interface. The new C-MAP Embark was designed to be intuitive so after a few minutes, you won’t really be looking for the manual to manage the basics like waypoints, routes and nav aids.

A funky feature includes the app changing color based on your environment, so the charts are always easy to read regardless of the surrounding light. The basics include a free download, but chart additions and weather data will be in-app purchases.

• Price: Free, with available in-app purchases

4. SeaPilot

SeaPilot sets an ambitious agenda for itself: it’s a basic navigation app (which has a free three-day trial) but it ramps up from there. You’ll need to upgrade to the premium version so you can add various chart areas, weather forecasting and routing capabilities. Beyond that, you can connect to Facebook to find nearby boating friends.

For sailors, there’s a database of polar diagrams which are graphs of the theoretical top speeds attainable by over 300 kinds of sailboats.

• Price: Three-day free trial, then starting at $7.99

5. i Sail GPS:NOAA USA Charts

For barebones basics, iSail is a great choice because it’s inexpensive and you can skip sign-ups and pop-ups. Measure distances to your waypoint, upload waypoints and routes and get quick ETAs to your next intermediate or final point.

iSail uses NOAA raster charts which are downloaded to the device so they can be used without Wi-Fi or out of cell range. There are few advanced features, but this app gets the job done when you need the basics. It’s for iOS only.

• Price: $7.99, with available in-app purchases

6. KnowWake

The best way to describe KnowWake is to compare it to a road-based app you’re probably already familiar with–Waze. Like Waze, KnowWake is crowd-source and will provide information on congested waterfront locations–coastal and on 350 inland waterways.

On a bustling weekend, you can see how busy marinas, restaurants, boat ramps, fuel docks, and dive and snorkel sites are. You can use it in North America, on the Great Loop and in Canada as well as in parts of the Caribbean. The app uses real-time updates and it has location-sharing between users so you can find friends.

• Price: Free!

All the boating apps above vary in price, complexity and focus, and although some are free, advanced features generally come at a price. Some take a bit of time to learn, but they’ll all put some peace-of-mind in your pocket the next time you slip the dock lines.

Bonus Apps: Boatsetter

Did you know Boatsetter has an app? Make that two! We’re proud to offer the largest peer-to-peer boat rental app that connects boat owners and boat renters, so you can get on the water without committing to boat ownership. Rent one of over 17,000 boats in 600 locations. Boatsetter isn’t the only private boat rental app , but it offers an exclusive partnership with BoatUS and Geico for insurance.

• Price: Free! (Boat owners should also check out our Boatsetter Owner’s app , perfect for stress-free boat rental management and easy communication with renters).
• Click here to download for iOS ; or click here to download for Android .

June 15, 2022

Sailing is one of the most ancient ways of getting around, but that doesn’t mean it has to be archaic. Today, there are tons of excellent sailing apps available to help enhance your seafaring experience. Sailing requires skill, and it can be hazardous to those who are inexperienced. Although technology can never replace sailing expertise, it can undoubtedly improve the quality of your time out on the water. You can learn from these apps and improve your sailing knowledge without buying books or paying for lessons. There’s plenty of apps available for sailors, and each has something of value to offer both onshore and offshore. From tutorial guides to navigation tools, here are the top ten best phone and tablet apps for sailing.

Table of contents

List of the Best iOS and Android Sailing Apps

1. knots 3d.

Thanks to careful boat design and engineering, sailboat rigs are more straightforward than ever. Sailing vessels from decades past once had enough rope to satisfy any scoutmaster, but now it’s a lot easier to sail without managing too many lines. Nevertheless, even new rigging requires a certain amount of knot expertise. Improperly tying knots can be disastrous at sea, and a bad dock tie-up can cause your boat to break away and drift. Not only that, but who wouldn’t want to impress the guys at the yacht club with impressive knot-tying abilities? Now, with the Knots 3D app, you can learn and master over a hundred essential sailing knots with ease. This app allows you to view the knot-tying process in three dimensions, which is a lot easier than looking at a static book page. You can use the app to improve your existing skills as well, and it’ll make you look like a champ while tying up at the dock. Knots 3D is available for $1.99 on both iOS and Android phones and tablets.

2. United States Coast Guard

This app is an absolute essential for anybody who sails in the United States. If you’ve owned a boat on U.S. waters, you’re certainly familiar with the Coast Guard and the essential work they perform every day. They’re the primary lifeline for sailors and boaters, and they also enforce the many maritime laws and regulations of this country. Remember, sailing isn’t like driving a car on the road. While you still have to follow the rules, you don’t need to do anything wrong to be ‘pulled over’ out on the water. The Coast Guard can (and often does) board you for no reason at any time. They do this to ensure you follow all of the mandatory safety and environmental regulations that apply to your boat. The Coast Guard app will help educate you about the rules, which will keep you safe and ensure you don’t receive a citation for a preventable violation. The Coast Guard’s rules are reasonable, but you have to know them to follow them.

This app isn’t just about following the law. It also gives you access to the latest weather updates from nearby NOAA buoys, which helps you navigate and prepare for foul weather. The Coast Guard regularly updates the app when they find new navigational hazards and allows you to report them as well. Along with the mandatory VHF radio, the Coast Guard app is an excellent navigational and safety tool to take along on every sailing journey. The Coast Guard App is available free for both iOS and Android.

3. Go Sailing

Go Sailing is an excellent app to connect with other sailing enthusiasts and find the best local spots when you’re out cruising. It’s a social media platform for sailors, and it’s a great way to meet people who share the hobby. Others often use the app to find other sailors to join them on their trips, and others use it to find crew members or spare parts in an emergency. It’s always great to be part of a community, and this app can help you find people who can be a great asset during your sailing trips.

A social network can be a great tool to improve a sailing trip, especially if you’re cruising to a new area. You can use the app to get in touch with the locals and attend events or secure supplies when you’re unfamiliar with the area. The user interface of this app is seamless; it works great, plus it’s fun to connect with people over a mutual enjoyment of sailing. The Go Sailing app is available free for iOS and Android.

4. AyeTides

One of the most significant hazards of sailing in a harbor is tide changes. Every year, hundreds of boats run aground or damage their hulls in shallow water. Many prudent sailors have gotten stuck at some point in their sailing career, and it’s a massive inconvenience (if not serious safety problem) whenever it occurs. Usually, people run aground due to inexperience or insufficient tide data, which is an understandable reason to have an accident. Now with the AyeTides app, you can access real-time and accurate tide data from over 12,500 locations around the world. AyeTides takes the guesswork out of navigating shallow waters. This gives you the ability to avoid hazards and plan ahead of time without complicated and inaccurate tide estimates.

While it’s still necessary to have tide charts, the app can help confirm information and keep you and your boat away from dangerous shallow areas. AyeTides keeps you up-to-date with the best available data so you’ll be in the know as conditions change. It can also help you predict future conditions to decide where (and where not) to anchor for the night, which is always a big plus. The AyeTides app is available for iOS for $7.99.

5. Cruisers Sailing Forum

Forums are one of the best online resources for how-to tutorials, troubleshooting, and locating hands-on experience from other sailors. The Cruisers Sailing Forum app gives you easy access to the renowned online platform, along with access to all of its recent and archived content. The forum offers excellent resources for sailors, and it’s a great place to ask a specific question and find somebody with the experience to answer it. Thousands of Cruisers Sailing Forum members contribute regularly, and there’s information about virtually everything already there. When you have a problem with your rigging or just need to find a good local spot to fish, you can post a question to the forum and get an answer from somebody who knows.

Forums are an incredible perk of modern technology, and the Cruisers Sailing Forum app makes it easy to access a priceless trove of information all from your phone or tablet. Resources are available there not only for boat maintenance and repair but also for great local spots and sailing locations that you may have never found otherwise. There’s a great community on the forum, and it’s certainly worthwhile to join and introduce yourself. You can bring along the answers wherever you go and use it any time you need. The Cruisers Sailing Forum app is available free for both iOS and Android devices.

6. SailFlow

Sailflow is an excellent app for planning a sailing trip, or for using on the water to get accurate weather information. The SailFlow app uses real-time and precise weather data from over 50,000 weather stations around the globe. This information is vital for both planning trips and predicting weather conditions. While accurate weather data is available elsewhere, it always helps to have a handy app that’s easy to interpret and available on the go.

Reliable weather information is always beneficial when you’re out sailing. A weather radio is a great tool to have also, but not every dangerous weather condition is broadcast over the air. A severe thunderstorm warning over the radio can certainly help keep you safe, but it doesn’t take a particularly powerful storm (which would be harmless on land) to cause significant issues over the water. With the SailFlow app, you can screen incoming weather conditions and determine for yourself if it’s safe to keep sailing. The SailFlow app is available free for iOS and Android, but there’s a pro version available too that offers some great perks.

The INavX app is the app you need for precise and accurate navigation. It features many excellent navigational tools, including up-to-date charts that are on-demand whenever you need them. The INavX app works with your onboard GPS and enhances navigation with ease. You can use it to monitor weather, check on tides, and find the best local places to go wherever you sail. You can use it to pin a previous location, so it’ll always be easy to find that great spot again. Remember, it’s still essential to have proper training in the use of charts to navigate waterways. INavX is not a replacement for charts and GPS systems. Instead, it’s an extremely handy addition to your navigation toolkit, and it offers a ton of great digital features that you wouldn’t have access to on paper or in a traditional navigation system. The INavX app is available for $14.99 on iOS.

8. Fast Track GPS Tool

Here is another great GPS and navigation app for sailors. It’s called the Fast Track GPS app, and it offers plenty of great navigational aids for sailing and boating. Like most traditional GPS apps, it features real-time location services to serve as a cross-reference with your primary navigation systems. Additionally, it has a large database of waypoints to assist in navigating areas where the information may not be as clear. The FastTrack GPS app also features live weather information and forecasting to ensure safe passage when other weather data is unavailable or unclear. This app allows the user to precisely pinpoint and save their location, which helps keep track of where you’re going and where you’ve been so far. It also includes live wind direction data, which can help you decide where to go and when to tack. In addition to an onboard radar system, you can also use this app as a proximity-alert device to help avoid collisions with the shore or unsafe and shallow waters.

Charts and proper navigation systems are still vital for safely navigating, along with a real person on watch in case somebody makes a mistake. However, this app provides some extra resources which can be extremely handy, especially when traveling in unfamiliar areas. The Fast Track GPS Tool is available on Android devices for free.

9. BoatUS App

Being a member of BoatUS is a lot like AAA for motorists, and it’s a fantastic way to add a sense of security to your trip. Mechanical failures and accidents at sea can be a total nightmare, and BoatUS can help ease some of those worries so you can enjoy your time on the water headache-free. The BoatUS app gives you access to 24/7 boat towing in many locations, just in case something happens, and you need assistance. In addition to towing and dockside assistance services, the BoatUS app is also a great resource for important marine data including forecasts and small craft advisories. With notifications turned on, you’ll get a buzz every time a weather authority shares an advisory or warning that you’ll need to know.

BoatUS doesn’t just deal with sailing hazards—they also provide great location-based information on discounted goods and services such as fuel and mooring. Their resources include locations and prices for services such as boat repair, dining, parts, mooring, and fishing information too—it’s your local guide that fits in your pocket. They also have a location-based map of West Marine stores so you can stock up on spare parts or accessories for your boat when out of town. You can use it to share your location to friends and family on social media, and also automatically via text and location so somebody always knows your recent position. This well-rounded and useful sailing app is available free for iOS and Android, but you’ll need to sign up for access to towing services.

10. PredictWind Marine Forecasts

Here’s another great weather app for sailing, and it features plenty of great tools to help you stay in the know. This isn’t any old weather app—it features full resolution maps, tables, and charts constantly updated with live data. Using the PredictWind app, you can monitor real-time wind speed and direction reports on an interactive map, along with temperature data and live forecasts. This app has uses a proprietary PWG and PWE marine weather monitoring system, with ECWMF and GF5 models, ensuring pinpoint accuracy, reliable forecasting, and excellent resolution. Also, the app is designed to be easy to use, allowing you to find and interpret important weather data without trouble or confusion. This is a very handy app to have around, and it can help you chart a course in confidence. The PredictWind Marine Forecasting app is available for free on iOS and Android.

However you choose to sail, you can benefit from one (or many) of these useful apps. We shouldn’t rely entirely on technology when sailing, but it can be very helpful to have around to make the experience more enjoyable. We can now access information and tools that mariners never had before, and it makes sailing easier and safer for everyone. Check out these apps and see for yourself how they can enhance your time out on the water.

5 Best Marine Navigation Apps for Boaters

If you have a boat (or you're thinking about buying a boat ) and you have a cell phone, you’re probably interested in learning all about the best boating apps . And among the many types of boating apps out there, marine navigation apps are some of the most useful. With the best marine navigation apps you can quite literally turn your phone or your tablet into a full-blown chartplotter. That means you have a valuable back-up to the electronics at your helm, and you can carry your tech with you even when aboard small boats with no electrical systems.

We’ve put a number of marine navigation apps to the test through the years, and these are our favorites (in alphabetical order):

C-Map Embark

Maptech iplot.

C-Map has been creating digital charts for years and has had other nav apps in the past, but Embark recently replaced previous offerings. The concept behind developing this next-gen nav app was to make it as simple and easy to use as possible. It’s a goal C-Map reached, and although this does by design make it one of the more simplistic apps in our round up, that’s one of the reasons why we love it – it’ll take you all of 30 seconds to figure out how to accomplish essential navigational tasks like going from point A to point B. Nifty bonus feature: the app can “see” the lighting situation you’re in and automatically adjust color and contrast for the best viewing.

Price: Free basic version with in-app purchases of varying costs for some map access and weather data.

Click here to download.

iNavX provides you with amazing latitude in the charts you choose to navigate with, and has eight different providers in their in-app chart store (NOAA charts come free). This app also allows you to do much more than simple navigational tasks, with quite advanced functionality like overlaying GRIB files (a form of current weather data) on your chartplotter screen, or connecting with NMEA (National Marine Electronics Association) compatible instruments on your boat via WiFi to display things like engine data and AIS (Automatic Information System, which uses transponders on commercial ships and boats to broadcast information regarding things like identification, speed, course, and destination) data. Figuring out the navigational basics isn’t made overly-complex by the additional features, but using the advanced functions will take some studying up.

Price: $4.99 for Apple plus in-app purchases; free for Android’s basic version, $19.99/year for the enhanced Pro version.

If you have an apple device (there’s no Android version) Maptech’s iPlot is a navigation app you’ll love for its intuitive nature. The app’s amazingly easy to figure out and thanks to the use of raster charts (digitized NOAA paper charts) when you zoom in you can make the hard-to-read depth sounding and marker numbers as large as you’d like. Plus “quilting,” (digitally stitching charts together) happens quickly so you don’t lose the view while zooming, a problem you may encounter with some other apps. What really sets this one apart from the pack, however, is its facility locator feature. Marinas, yacht clubs, and other waterfront facilities are not only detailed on-screen, but when you tap on them, it takes you to their website—an ability those going on an overnight or weekend getaway to unfamiliar ports will definitely enjoy.

Price: $39.99 with basic charts; $9.99 for additional charts.

Navionics lays claim to being the most popular boating app available, and its navigational features and functions are comprehensive, to say the least. In fact, it offers many features that some modern chartplotters can’t match. Dock-to-dock auto-routing, for example, creates a route from point A to point B taking things like nav aids and your boat’s draft constraints into account, when you merely tap the beginning and end points. The Sonarchart Live function lets you create bathymetric maps of the area you’re boating in, in real time. User-generated community edits can be displayed with daily updates. And these are just some of the highlights in a long list of unique features.

Price: A two-week trial comes free, then the subscription varies depending on the chart region(s) you want ($14.99 to $54.99).

Seapilot is a fairly comprehensive navigation app (though some of the more advanced features, like routing and weather forecasting, require upgrading to the premium version), which introduces a different twist into the mix: Facebook integration. Connected friends are displayed like AIS targets on the app, so finding each other and linking up on the water is easier. Seapilot is also unusual in that it can offer polar diagrams (which show the theoretical attainable speed depending on wind direction and speed) for over 300 boats, to determine the ideal path to steer a sailboat taking wind and current forecasts into account.

Price: Free basic three-day-trial version, $7.99 to $64.99 depending on chart area subscriptions.
