Subelement C: Equipment Operations— Topic 14: VHF Channel Selection
Question 1-14C5
Element 1 (MROP)Which channel would most likely be used for routine ship-to-ship voice traffic?
Explanation
Channel 08 is specifically designated as a simplex intership working channel for non-commercial vessels. This makes it the most appropriate choice for routine, direct ship-to-ship voice communications once initial contact has been made.
Channel 16 is the international distress, safety, and calling channel. While vessels make initial contact on Ch-16, routine voice traffic must immediately move to a working channel to keep Ch-16 clear for emergencies and new calls.
Channel 70 is exclusively reserved for Digital Selective Calling (DSC) alerts and is not used for voice communications.
Channel 22A is a U.S. Coast Guard liaison channel, used for communications between vessels and the Coast Guard, or for passing urgent information during emergencies, not for general routine ship-to-ship traffic.
