BOTH INTERNATIONAL & INLAND You are the stand-on vessel in a crossing situation. How long may you hold your course and speed?

Correct Answer: Option A — until action by the give-way vessel alone will not prevent collision

Rule 17(a)(ii) mandates that the stand-on vessel may take action to avoid collision by her maneuver alone as soon as it becomes apparent that the give-way vessel is not taking appropriate action in compliance with the Rules. You must maintain course and speed until this critical threshold is reached.
