§27.205. What are the requirements for internal communication systems on towing vessels?
46 C.F.R. § 27.205
You must ensure that your vessel is fitted with a communication system between the engine room and the operating station that—
Consists of either fixed or portable equipment, such as a sound-powered telephone, portable radios, or other reliable method of voice communication, with a main or reserve power supply that is independent of the electrical system on your towing vessel; and
Provides two-way voice communication and calling between the operating station and either—
The engine room; or
A location immediately adjacent to an exit from the engine room.
Twin-screw vessels with operating-station control for both engines are not required to have internal communication systems.
When the operating-station's engine controls and the access to the engine room are within 3 meters (10 feet) of each other and allow unobstructed visual contact between them, direct voice communication is acceptable instead of a communication system.
