Raymarine’s Ray73 radio is communications central for your boat with built-in VHF, AIS receiver and loudhailer capabilities. Built on our full-sized marine radio chassis, the Ray73 comes with oversized controls and a big screen for easy operation offshore. The Ray73 also supports optional wired or wireless RayMic controllers for true multi-station control and intercom capability. When connected to an optional hailing horn, the Ray73 can generate automatic fog signals and work as a public address announcement system.
