BOTH INTERNATIONAL & INLAND What must be TRUE in order for a stand-on vessel to take action to avoid collision by her maneuver alone?

Correct Answer: Option D — All of the above

Rule 17(a)(ii) permits the stand-on vessel to take action when the give-way vessel fails to act. This requires that the vessels be in sight of each other, there is a risk of collision, and the stand-on vessel has determined the give-way vessel is not taking appropriate action.
