What channel is designated for Bridge to Bridge communications?

• A. 13
• B. 16
• C. 9
• D. 22A

Answer: (A)

The channel set aside for Bridge-to-Bridge communications is Channel 13 (156.650 MHz). This working channel is reserved specifically for ships maneuvering in close proximity to coordinate actions, such as passing through narrow channels, locks, or approaching docks. Using this dedicated channel helps keep the primary calling channel free for hails and emergencies, and it provides a clear, common medium for exchanging maneuvering information.

Channel 16, by contrast, is the international distress, safety, and calling channel, so it’s kept clear for emergencies and initial contact rather than routine bridge coordination. The other channels listed aren’t designated for Bridge-to-Bridge communications, as they serve different purposes in various regions and situations.
