Rules of the Road Question 783 diagram
A engaged in fishing
B mine sweeping
C a pilot boat
D under sail
AI Explanation

The correct answer is D) under sail. The lights displayed in the illustration D062RR indicate that the vessel is under sail at night. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel under sail is required to display a combination of sidelights (red and green) and a stern light (white) when underway at night. This lighting configuration, as shown in the illustration, is the proper signal for a sailing vessel operating in both international and inland waters. The other answer choices are incorrect because they do not match the lighting requirements for a vessel under sail. A fishing vessel, a mine sweeper, and a pilot boat would have different light configurations that do not match the one shown in the illustration.
