BOTH INTERNATIONAL & INLAND Which lights shall a power-driven vessel towing another vessel astern (tow less than 200 meters) show?

AI Explanation
The correct answer is C) two masthead lights in a vertical line instead of either the forward or after masthead lights. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a power-driven vessel towing another vessel astern where the length of the tow, including the length of the towing vessel, is less than 200 meters, shall exhibit two masthead lights in a vertical line. This configuration replaces the requirement for either the forward or after masthead light. The other options are incorrect because they do not match the COLREGS requirement for a power-driven vessel towing another vessel astern with a tow less than 200 meters. Option A is for a longer tow, option B is for a different type of vessel, and option D does not meet the masthead light requirement.
