Question 779 Rules of the Road

The correct answer is A) The colored sidelights and a white stern light. According to the International and Inland Navigation Rules, a vessel that is being towed astern must display the same navigation lights as a power-driven vessel underway, which includes the colored sidelights (red and green) and a white stern light. This is required to indicate the vessel's presence, size, and direction of travel to other vessels in the area. The other options are incorrect because B) showing no lights would not provide sufficient visibility, C) the full set of lights for a power-driven vessel underway is not necessary for a vessel being towed, and D) a single white light forward and aft is not the correct lighting configuration for a vessel being towed.
