Question 241 Rules of the Road

The correct answer is C) Vessel "B" is the stand-on vessel because it is to starboard of vessel "A". This is correct because under the International Regulations for Preventing Collisions at Sea (COLREGS), Rule 15 states that when two power-driven vessels are crossing, the vessel that has the other on its own starboard side is the stand-on vessel. In this case, vessel "B" is to the starboard side of vessel "A", so vessel "B" is the stand-on vessel. The other answer choices are incorrect because A) vessel "A" is not the stand-on vessel simply because it is pushing ahead, and B) and D) are wrong since vessel "B" is the stand-on vessel in this crossing situation.
