BOTH INTERNATIONAL & INLAND A 50-meter vessel is towing astern and the length of the tow is 100 meters. In addition to sidelights, which lights are required to be shown to fully comply with the Rules?

Correct Answer: Option A — A masthead light forward, two masthead lights aft, a stern light, and a towing light above the stern light

Rule 24(a) requires a vessel towing to show two masthead lights in a vertical line if the tow exceeds 50 meters. For a 50-meter vessel, the forward masthead light is required, plus two masthead lights aft, a stern light, and a yellow towing light above the stern light.
