Diagram for question 765
AI Explanation
The correct answer is B) sailing. The light shown in illustration D046RR is the combination of a masthead light, sidelights, and a sternlight, which is the lighting configuration required for a sailing vessel at night under both the International and Inland Navigation Rules. This lighting arrangement allows other vessels to identify the sailing vessel's direction of travel and navigation status. The other answer choices are incorrect because: A) a pilot boat would typically display different lights, C) a fishing vessel at anchor would display an all-around white anchor light, and D) a fishing vessel underway would display different sidelights and possibly additional fishing vessel lights.
