Question 871 Rules of the Road

The correct answer is D) All of the above. In a situation where a vessel is towing astern in an operation that severely restricts the towing vessel and its tow in their ability to deviate from their course, the lights that must be exhibited are: 1) The lights for a vessel restricted in its ability to maneuver (as per Rule 27 of the International Regulations for Preventing Collisions at Sea). 2) The masthead lights for a towing vessel (as per Rule 24 of the Regulations). 3) Sidelights, stern light, and towing light (as per Rule 24 of the Regulations). The other options are incorrect because they do not fully encompass the lighting requirements for a vessel in this specific towing scenario, which necessitates the display of all three sets of lights mentioned in the correct answer.
