What is the primary consideration when crossing a channel if another vessel in the channel can only navigate within the channel?

• A. Do not cross the channel if you might impede the other vessel
• B. Cross the channel and pass to port
• C. Maintain your position and speed
• D. Stop and wait for the other vessel to clear

Answer: (A)

In narrow channels, vessels that can navigate only within the channel have the priority. Your main concern is whether crossing would interfere with that constrained vessel’s ability to maneuver. If crossing would impede it, you must not cross. The correct approach is to wait or take action to keep clear so the other vessel can pass safely. Crossing the channel and passing to port or simply maintaining your speed would not address the risk of blocking the vessel that’s confined to the channel. Stopping and waiting is a safe option, but the core rule is the obligation not to cross if you might impede the constrained vessel.
