BOTH INTERNATIONAL & INLAND You are in charge of a stand-on vessel in a crossing situation. The other vessel is 1.5 miles to port. Which action should you take if you believe that risk of collision exists?

Correct Answer: Option C — take avoiding action only after providing the give-way vessel time to take action, and determining that her action is not appropriate

Rule 17(a)(ii) permits the stand-on vessel to take action to avoid collision only when it becomes clear that the give-way vessel is not taking appropriate action. You must first provide the give-way vessel sufficient time and opportunity to fulfill her obligation to keep clear before you maneuver.
