Rule 11 addresses which scenario?

• A. Narrow channels
• B. Vessels in sight of one another
• C. Traffic Separation Schemes
• D. Overtaking

Answer: (B)

Vessels in sight of one another are governed by the rules that apply when you can see another vessel. Rule 11 lays out how the standard collision-avoidance rules are applied when two or more vessels are in sight, guiding you to assess risk and choose the appropriate action based on how the other vessel is bearing relative to you (whether it’s a crossing situation, head-on, or overtaking).

Narrow channels focus on special precautions in confined waterways, Traffic Separation Schemes define lanes in busy areas, and the overtaking rule covers situations where one vessel is coming up from behind. Understanding that being able to see the other vessel activates Rule 11 helps you decide which specific actions to take based on the situation you’re in.
