A fixed VHF radio that brings multi-station communications to a complete new level of power, performance and flexibility. Ray91 has a black-box design with a transceiver that is hidden out of sight, whilst the ergonomic RayMic handset and remote speaker provide full control of the radio with crystal clear audio.

The marine VHF radio is equipped with an integrated automatic identification system (AIS) receiver, so can be used to receive navigation and safety broadcasts from other nearby AIS-equipped vessels, then share them over NMEA2000 and NMEA0183with compatible multi-function displays. AIS equipped vessels are easily identifiable along with their vessel name, course, speed, CPA and other voyage information.

Channel scanning, dual-watch, tri-watch and weather alert are standard features. There's also Class D Digital Selective Calling radio and integrated GPS that make 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. A powerful 25-watt transmitter and commercial grade electronics ensure a long life and superior performance.

Ray91's position tracking feature can keep tabs on up to 5 nearby DSC equipped vessels, automatically sharing their positions with your Raymarine multi-function display. You're also able to keep an eye on other boats within your cruising party, monitor vessels of interest or manage your local fleet. In addition, the VHF radio supports the ATIS system on navigable inland waterways.

The VHF radio has a built-in loudhailer that will make you heard on deck and across the harbour. There's also the option to connect an optional hailing horn and make your presence known with 30 watts of audio output, plus 2-way talkback. When visibility is low and the fog rolls in, the loudhailer can also be set to automatically sound required fog signals for power and sailing vessels underway and at anchor.

Ray91's transceiver unit is cast in solid aluminium for shock and vibration resistance, as well as maximum heat dissipation. In addition, the RayMic handset has a super-bright backlighting for easy viewing in all conditions, plus oversized keys that provide a sure grip with easy access to commonly used functions. This results in a waterproof and ruggedized radio setup.
