Which channel is typically used for bridge-to-bridge communication?

The correct channel for bridge-to-bridge communication is Channel 13. This channel is primarily designated for navigational safety and is used by vessels to communicate with each other when navigating in proximity, particularly when it comes to maneuvering or discussing intentions that could affect safe navigation. Channel 13 is considered a working channel for vessel-to-vessel communications in congested or narrow waters, helping to avoid accidents and promote safe passage.

In this context, while other channels may serve specific purposes—such as Channel 16 being the international distress frequency, and Channel 68 often used for recreational vessels—Channel 13 has been established as the standard for bridge-to-bridge communications. This distinction ensures that all vessels follow a consistent protocol, improving overall maritime safety.
