How many crewmembers can be logged on to a channel in the 47 FT / RB-M system?

In the 47 FT / RB-M system, a total of five crewmembers can be logged on to a channel. This includes both the operational crew and any additional personnel that may be part of the expected mission or situation.

Having knowledge of how many crewmembers can operate effectively within a vessel’s communication system is crucial for ensuring proper coordination and safety. The designated number allows for an organized structure during operations, enabling clear communication and effective task management during missions.

Other options suggest fewer crewmembers, which would not suffice for the various roles typically necessary in maritime operations, such as a helmsman, throttle operator, lookout, and other support roles required to maintain alertness and readiness for emergency response situations.
