Question 255Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND In illustration D005RR below, vessel "A", which is pushing ahead, and vessel "B" are crossing. Which is the stand-on vessel?

Diagram for question 255
AI Explanation
The correct answer is B) Vessel "B" is the stand-on vessel because she is to starboard of vessel "A". According to the International and Inland Navigation Rules, when two power-driven vessels are crossing, the vessel that has the other on her own starboard side is the stand-on vessel and must maintain her course and speed. In this case, vessel "B" is to the starboard side of vessel "A", so vessel "B" is the stand-on vessel and must hold her course and speed. The other answer choices are incorrect because: A) Vessel "A" is the give-way vessel, not the stand-on vessel; C) One of the vessels must be the stand-on vessel according to the rules; and D) The relative positions of the vessels, not which one is to port, determine the stand-on vessel.
