847. 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?

As the stand-on vessel in an international crossing situation, vessel A must maintain course and speed; vessel B, having A on its starboard side, is the give-way vessel and signals a course alteration to starboard, which does not require a response from vessel A.
