BOTH INTERNATIONAL & INLAND Every vessel which is directed by these Rules to keep out of the way of another vessel shall, if the circumstances of the case admit, avoid which action?

Correct Answer: Option A — crossing ahead of the other

Rule 16 requires a give-way vessel to take early and substantial action to keep well clear. Rule 15 and Rule 17 imply that crossing ahead of the stand-on vessel is dangerous and should be avoided if the circumstances of the case admit, as it creates a high risk of collision.
