BOTH INTERNATIONAL & INLAND Vessels "A" and "B" are crossing as shown in illustration D026RR below. Which statement is TRUE?

Correct Answer: Option A — Vessel "A" must keep clear of vessel "B".

Rule 15 dictates that when two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way. Vessel A has Vessel B on its starboard side, making Vessel A the give-way vessel.
