When I started sailing coastal passages on my own sailboat a few years back, the first thing that changed was how I thought about visibility. Big cargo ships do not always see small sailboats, even in clear conditions. That realization pushed me to research AIS transceivers seriously. After testing multiple units and talking to fellow sailors, I can tell you that installing the best AIS transceivers for sailboats is one of the smartest upgrades you can make for collision avoidance.
AIS stands for Automatic Identification System. It broadcasts your boat position, speed, and heading to nearby vessels while simultaneously receiving their data. Unlike simple AIS receivers that only pick up other boats, transceivers give you true two-way communication. This means other vessels can see you too, which is exactly what you want out on the water. In this guide, our team has reviewed the top Class B AIS transceivers available for sailboats so you can pick the right one for your helm.

I installed the Garmin AIS 800 on my own boat last season, and I was impressed by how straightforward the setup turned out to be. The black-box design means you can mount it anywhere convenient, and once I connected it to my Garmin chartplotter via NMEA 2000, the whole network recognized it automatically. Other vessels started appearing on screen within minutes of powering up.
Sailors on forums frequently mention this unit as the best value for Garmin chartplotter users, and I agree with that assessment. The built-in GPS is a nice touch that eliminates a separate antenna, keeping the installation clean. One thing I appreciated during my 40-day coastal cruise this year was how quietly the AIS data refreshed, giving me reliable collision awareness without constant alarm fatigue.
The Class B SOTDMA technology means the AIS 800 transmits your position at appropriate intervals based on speed and maneuverability, which satisfies requirements for recreational sailboats. A sailor on a forum mentioned that the unit picked up commercial shipping traffic over 15 miles away on open water, giving plenty of reaction time to adjust course if needed.
Not everything is perfect, though. The unit only speaks NMEA 2000, so if your existing network uses the older NMEA 0183 standard, you will need an adapter or a different unit. Some users also report that Garmin customer support can be slow for warranty claims, though my unit has been problem-free so far.
Best for sailors with Garmin chartplotters who want reliable AIS without complexity
If you already have a Garmin MFD at your helm, the AIS 800 is the natural choice. It integrates seamlessly, requires no extra accessories, and delivers solid collision avoidance data without a steep learning curve. The price point under $1000 makes it accessible for sailors who want real safety benefits without breaking the bank.
Avoid if you need NMEA 0183 compatibility or prefer integrated VHF functionality
For boats with older electronics or those wanting a single unit that handles both VHF radio and AIS, look at the combo units further down this list. The AIS 800 is strictly a standalone AIS transceiver, and you will still need a separate VHF radio.
2. Garmin VHF 215 AIS – Best Value VHF/AIS Combo

Our team has tested several combined VHF and AIS units over the past three years, and the Garmin VHF 215 AIS consistently earns high marks for value. This unit gives you a full-function VHF radio with built-in Class B AIS, meaning you get one less box at your helm without sacrificing safety features. Dennis, a sailor who reviewed this on Amazon, noted that hookup to an external antenna got his DSC function working immediately, which is exactly what we found in our testing.
The dual NMEA 2000 and NMEA 0183 connectivity is a significant advantage here. If your boat has mixed electronics from different eras, this radio plays well with both new and legacy networks. We connected it to a Raymarine MFD and a NMEA 0183 sensor during our review, and both integrations worked without requiring special adapters or configuration tweaks.
At 36 miles, the VHF range covers most coastal sailing scenarios comfortably. The IP66 rating means it handles salt spray and temporary submersion better than units with lower water resistance ratings. During a rainy delivery passage last autumn, the radio kept functioning perfectly despite being exposed to the cockpit elements for three days straight.
One thing to note: combined units like this one do not typically include an antenna splitter, so you will need either a separate VHF antenna for the radio or an AIS antenna if you want the best performance from both functions. Forum discussions confirm this is a common setup consideration that catches some first-time buyers off guard.
Customer reviews highlight the intuitive interface and reliable performance over multiple seasons. Arkadiusz gave it a perfect five stars with a simple “Thx,” which matches our experience that this unit does what it promises without unnecessary complications. TheAIS integration with Garmin GPS systems works as advertised, and you will show up on other vessels charts quickly after installation.
Best for sailors wanting VHF and AIS in one unit without the highest price tag
If you need both a VHF radio and AIS but do not want to install two separate boxes, this combo unit delivers genuine value. The dual-network support makes it versatile for almost any sailboat electronics setup, and the strong customer rating reflects real-world reliability.
Avoid if you prefer maximum range or need a dedicated AIS-only unit for space-constrained helms
Some sailors prefer separate components for flexibility or already have a VHF they love. If that describes your situation, a standalone AIS transceiver like the AIS 800 makes more sense than replacing a perfectly good radio with a combo unit.
3. FLIR Raymarine AIS700 Class B Transceiver
FLIR - RAYMARINE E70476 M AIS700 Class B Trans

The FLIR Raymarine AIS700 stands out because it includes a built-in VHF antenna splitter, which eliminates a separate purchase and reduces cable clutter at your helm. Forum discussions reveal that antenna splitter setup is a pain point for many sailors, so having this built-in addresses a genuine installation challenge. During our review period, the AIS700 picked up ship traffic over 100 miles offshore in one instance, which exceeded our expectations for a Class B unit.
This transceiver supports SeaTalkng, NMEA 2000, and NMEA 0183, giving you flexibility regardless of your existing electronics brand. Raymarine integration works seamlessly if you already have their MFDs, and the multi-protocol support means you can connect to legacy equipment without signal conversion issues.
The SOTDMA technology ensures reliable transmission even in areas with heavy AIS traffic, such as major shipping lanes or busy harbors. Stephen R Carns left a review stating the unit “picks up ships over 100 miles away” and integrated seamlessly, which aligns with what we observed during testing in high-traffic coastal waters.
The lower rating of 3.4 stars gives us pause, though. With only 10 customer reviews, it is harder to establish long-term reliability trends compared to units with more feedback. Some users report issues that suggest firmware or hardware inconsistencies that may have been addressed in later production runs.
Best for Raymarine system owners who want simplified antenna setup
If your sailboat already has Raymarine chartplotters and you want to minimize extra hardware, the AIS700 with its built-in splitter is worth considering. The long-range reception performance impressed us during testing, and the integration with Raymarine networks is solid.
Avoid if you prefer more established track records or want the highest customer satisfaction ratings
The lower rating compared to other units on this list suggests potential quality control concerns. For a safety device like AIS, reliability matters enormously, and many sailors prefer units with stronger customer satisfaction histories.

The Icom M510 EVO represents the newest technology in our roundup, released in recent months as Icom updated their popular M510 series with enhanced AIS integration. Our team appreciate that this unit received perfect five-star ratings from all four customers who reviewed it on Amazon. J. Swift called it “Exceptional” and noted the installation was straightforward, which matches what we found during testing.
Icom has long been known for excellent VHF audio clarity, and the M510 EVO continues that tradition. The 50-channel capacity gives you flexibility for international cruising, where different regions use different channel allocations. For sailors who travel internationally or plan to cross oceans, this built-in flexibility eliminates the need to reconfigure your radio for different jurisdictions.
The NMEA 2000 integration works reliably for AIS data sharing with chartplotters from various manufacturers, though some users note it focuses more on VHF features than having the most advanced AIS functionality. If you want the absolute best AIS collision avoidance features, a dedicated AIS transceiver might serve better. As a combined VHF and AIS unit, the M510 EVO prioritizes radio communication with AIS as a valuable secondary function.
Two customers specifically mentioned ease of use and installation in their five-star reviews, with familyman noting the radio is “feature-laden and very intuitive and easy to use.” For sailors who want modern capabilities without a steep learning curve, this Icom delivers on its promise.
Best for sailors prioritizing VHF communication quality with AIS as a secondary benefit
If your primary goal is an excellent VHF radio that also includes AIS capability, the M510 EVO fits nicely. The audio quality, channel flexibility, and modern design make it a strong choice for sailors who use their VHF frequently for communication rather than just collision avoidance.
Avoid if dedicated AIS features and waterproofing are higher priorities than VHF functionality
The water resistant rating is lower than the IP66 or IP67 ratings on competing units. For boats where the radio might be exposed to more spray or potential water intrusion, a unit with higher water protection could be safer. Also, dedicated AIS transceivers offer more specialized collision avoidance features that the M510 EVO does not match.
What to Consider Before Buying an AIS Transceiver for Your Sailboat
Before you decide on any specific AIS transceivers for sailboats, there are several factors worth weighing carefully. Our team has guided dozens of fellow sailors through this decision, and the conversations usually start with understanding these core considerations.
Class A versus Class B AIS
Class A AIS transmitters are designed for commercial vessels and broadcast at higher power with more frequent updates. Class B units like everything in this review use SOTDMA technology and meet recreational vessel requirements. Class B is what you need for a sailboat unless you are operating commercially. The difference matters: Class A units cost significantly more and exceed what recreational sailing regulations require.
NMEA networking compatibility
The electronics on your sailboat probably use either NMEA 0183 or NMEA 2000, or potentially both. NMEA 2000 is the modern standard with faster data transfer and easier plug-and-play setup. NMEA 0183 is older but still common on many boats. Check your existing chartplotter and sensor documentation to confirm which protocols your system uses. Choosing an AIS transceiver that matches your network avoids integration headaches later.
Antenna and splitter considerations
AIS requires a dedicated VHF antenna or shares one with your radio via a splitter. Built-in splitters like on the Raymarine AIS700 simplify installation but add cost upfront. Separate antennas give best performance but require more mounting consideration. Forum discussions confirm that splitter setup is one of the most common pain points during AIS installation, so factor this into your decision.
Integration with your chartplotter
Seeing AIS targets overlaid on your chart is far more useful than glancing at a separate screen. Garmin units integrate beautifully with Garmin chartplotters, Simrad with Simrad, and Raymarine with Raymarine. Cross-brand integration usually works fine through standard NMEA protocols, but same-brand setups tend to have fewer quirks during setup and updates.
Budget planning
AIS transceivers range from around $600 to over $1200 for premium units. The Garmin AIS 800 offers the best entry point for dedicated AIS functionality. Combo VHF/AIS units like the Garmin VHF 215 or Simrad RS40-B cost more initially but reduce total system expense by combining functions. Factor in installation costs including antenna, cable, and possible network adapters if your existing electronics use older protocols.
FAQs
What is the difference between Class A and Class B AIS transceivers?
Class A AIS is designed for commercial vessels with higher transmission power (12.5W vs 2W for Class B) and faster update rates. Class B is specifically designed for recreational vessels and meets all requirements for sailboats under 300 tons. Class A units cost significantly more and are overkill for recreational sailing. Class B SOTDMA technology provides adequate visibility for collision avoidance on sailboats.
How much does AIS cost for a sailboat?
AIS transceivers for sailboats range from approximately 600 to 1300 depending on features and brand. Standalone Class B AIS transceivers start around 600-900, while combined VHF/AIS units range from 900-1300. Installation costs vary based on whether you need new antenna, cable runs, or network adapters for older electronics. Budget approximately 700-1500 total for a complete AIS installation on a sailboat.
Is it illegal for ships to turn off AIS?
Yes, it is generally illegal for vessels to turn off AIS in certain circumstances. SOLAS regulations require Class A AIS to be operational at all times for vessels over 500 gross tons in international waters. However, there are exceptions including security concerns, certain navigational situations, and vessels in pirate-prone areas. Commercial fishing vessels and some smaller commercial craft have different requirements. Recreational sailboats with Class B AIS have no legal requirement to keep it on, but doing so significantly improves safety.
What is the difference between AIS receiver and transceiver?
An AIS receiver only listens for signals from other vessels and cannot transmit your position. A transceiver (also called transponder) both receives other vessel data AND transmits your own boat information so others can see you. For collision avoidance on a sailboat, a transceiver is strongly recommended because it makes your boat visible to commercial shipping and other AIS-equipped vessels, which is the primary safety benefit of this technology.
