Best AIS Systems for Cruising Sailboats in 2026

Choosing the right AIS transponder is one of the most important safety decisions you’ll make as a cruising sailor.

The models below represent the most reliable, well supported AIS transceivers available today. They’re all Class B units, easy to install, and proven by thousands of long distance cruisers.

Buyer’s Guide — How to Choose an AIS Transponder

When choosing an AIS transponder, the biggest decision is Class B/SO vs Class B/CS. Class B/SO transmits more frequently and at higher power, making you more visible to ships — worth the extra cost for offshore sailing.
Next, consider integration. If you’re running a Garmin network, the AIS 800 is the obvious choice. For mixed-brand systems, em trak units are universally compatible and extremely reliable.
Finally, look for internal GPS, NMEA 2000, and silent mode. All three models above tick those boxes, making them ideal for modern cruising boats.

Which AIS Should You Choose?

  • Choose Garmin AIS 800 if you run a Garmin network.
  • Choose em trak B922 if you want the best all round Class B/SO unit.
  • Choose em trak B900 if you want reliable performance at the lowest price.
