Question 777 Rules of the Road

The correct answer is D) a towing light above the stern light. According to the International and Inland Navigation Rules, a power-driven vessel with a 150-meter stern tow is required to display a towing light (yellow) above the stern light (white) to indicate the length of the tow. This configuration helps other vessels identify the presence and extent of the tow. The other options are incorrect because: A) does not accurately represent the required lights, B) describes the lighting configuration for a vessel engaged in towing another vessel, and C) describes the lighting configuration for a vessel that is not towing.
