Ray91 – Marine Modular VHF Radio System with Class B AIS Receiver

The Ray91 modular VHF radio brings dual-station communications and traffic management to a whole new level of power, performance, and flexibility. The Ray91 is a black-box design with a transceiver that hides out of sight while the ergonomic RayMic handset and remote speaker provide full control of the radio with crystal clear audio.

Key Features

• Black box, dual-station capable VHF radio
• Built-in Automatic Identification System (AIS) Class B Receiver
• NEW - Wireless handset and active speaker available
• Wired handset and passive speaker included
• Expandable to 2 RayMic handsets
• Built-in loudhailer and fog signal generator
• Optional external GPS receiver and Class D Digital Selective Calling
• Simple NMEA2000 and NMEA0183 Networking

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.

Loudhailer
Ray91’s built-in loudhailer will make you heard on-deck and across the harbor. 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.
