INTERNATIONAL ONLY Vessels "A" and "B" are in a crossing situation on the high seas as shown in illustration D014RR below. Vessel "B" sounds one short blast. What is the proper action for vessel "A" to take?

Correct Answer: Option A — Hold course and speed

Rule 17(a)(i) requires the stand-on vessel to maintain course and speed in a crossing situation. Even if the give-way vessel sounds a signal, the stand-on vessel's primary obligation remains to hold her course and speed until it becomes apparent that the give-way vessel is not taking appropriate action.
