The Ray91 is also equipped with an integrated Automatic Identification System (AIS) receiver. Us the Ray91 to receive navigation and safety broadcasts from nearby AIS-equipped vessels and share them over NMEA2000 or NMEA0183 with compatible MFDs. AIS equipped vessels can easily be identified along with their vessel name, course, speed, CPA, and other voyage information.

Communications Powerhouse

Ray91 is equipped with a powerful 25-watt transmitter and commercial grade electronics for long life and superior performance. Channel scanning, dual-watch, tri-watch and weather alert are standard. Class D Digital Selective Calling radio and integrated GPS makes setting up the advanced safety and calling features easy. Simply input your vessel’s MMSI number during setup and you’re ready to go. For GPS operation the optional GA150 passive GPS antenna is required.

Position Tracking

Use Ray91’s position tracking feature to keep tabs on up to 5 nearby DSC equipped vessels. Their positions are automatically shared with your Raymarine MFD. Keep an eye on other boats in your cruising party, monitor vessels of interest, or manage your local fleet. In Europe the Ray91 supports the ATIS system on navigable inland waterways.


Ray91’s built-in loudhailer will make you heard on-deck and across the harbour. Connect an optional hailing horn and make your presence known with 30-watts of audio output, plus 2-way talkback. When things get foggy, the loudhailer can be set to automatically sound required fog signals for power and sailing vessels underway and at anchor.

Waterproof & Ruggedized

Ray91’s transceiver unit is cast in solid aluminum for shock and vibration resistance and maximum heat dissipation. RayMic handsets feature super-bright backlighting for easy viewing in all conditions and oversized keys provide a sure grip with easy access to commonly used functions.

The Ray91 system includes 1 wired handset and a passive speaker kit. Expand your system with an additional wired station to keep you in communication from the tuna tower, flying bridge, helm, salon or even in staterooms!

No matter how small or how large your vessel is, the Ray91 from Raymarine has all the power and performance you need for essential communications, safety and situational awareness on the water.
