Diagram for USCG Rules of the Road: BOTH INTERNATIONAL & INLAND Which vessel that is underway at night is required...
A engaged in trawling
B a pilot boat
C minesweeping
D under sail
AI Explanation

The correct answer is A) engaged in trawling. The illustration D069RR shows the required navigation lights for a vessel engaged in trawling, which includes two all-around green lights in a vertical line. This lighting configuration is specified in the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules for vessels underway at night. The other answer choices are incorrect because pilot boats, minesweepers, and sailboats have different navigation light requirements that do not match the illustration.
