Question 147 Rules of the Road

The correct answer is B) the give-way vessel. In this scenario, the power-driven vessels are crossing, and Vessel "A" sounds one short blast on the whistle. According to the International Regulations for Preventing Collisions at Sea (COLREGS), the vessel that sounds the one short blast is considered the give-way vessel, which must take early and substantial action to keep well clear of the other vessel. The other options are incorrect because: A) the stand-on vessel is the vessel that maintains its course and speed, which is not the case here; C) the overtaking vessel is the vessel that is overtaking another from a direction more than 22.5 degrees abaft the beam of the other vessel, which is not the situation described.
