Which COLREGs rule addresses vessels in sight of one another?

• A. Rule 12
• B. Rule 11
• C. Rule 5
• D. Rule 7

Answer: (B)

Vessels in sight of one another are governed first by the rule that provides the overall framework for sighted traffic. This rule requires you to use all available means to determine whether there is a risk of collision and to act in accordance with the specific rules that apply to the situation (such as overtaking, crossing, or head-on). In essence, it sets the stage for how you apply the rest of the collision-avoidance rules once you can see the other vessel. Remember, the fundamental duties like maintaining a proper lookout and keeping a safe speed still support this process, but the umbrella rule for vessels in sight is the one that directs how you evaluate risk and choose the appropriate action.
