Which channel is identified for ship-to-ship communication?

The channel identified for ship-to-ship communication is channel 13 (156.650 MHz). This channel is specifically designated for intership navigational communications. It facilitates safety-related communications between vessels, allowing them to coordinate maneuvers, share critical information about navigational hazards, and communicate during emergencies.

Channel 16 (156.800 MHz) is the international distress, safety, and calling frequency. While it is widely used for ship-to-shore communication, primarily to contact coast stations, it can also be used for ship-to-ship calling in emergency situations. However, for routine communications between ships, channel 13 is preferred.

Channel 11 is mainly used for communication with U.S. Coast Guard stations and is not specifically designated for ship-to-ship dialogue. Channel 22A is often used for non-commercial communications and can facilitate communication with shore stations. Therefore, while these channels are important for maritime operations, they do not hold the same primary function as channel 13 for ship-to-ship communication.
