A masthead control system and method are provided for a sailing vessel to reduce the number of cables running inside the mast to a single coaxial cable carrying power, control and data signals, and VHF radio signals. The coaxial cable connects an antenna directly to a VHF radio communications device such that radio communications are always available in case of emergency. The system comprises an instrumentation center that connects to the masthead; at least one masthead device that connects to the instrumentation center; and a cable, such as a coaxial cable, that connects the instrumentation center to an interface unit located in the hull. The cable carries power, at least one radio frequency signal, and at least one data or control signal between the instrumentation center and the interface unit.
