Question 648 Rules of the Road

The correct answer is D) not required to show any anchor lights. According to the International and Inland Navigation Rules, vessels less than 7 meters (approximately 23 feet) in length and not engaged in towing while at anchor are not required to display any anchor lights. The reasoning is that these smaller vessels are generally not navigating in areas with a lot of other vessel traffic, so the presence of anchor lights is not as critical for collision avoidance. The other options are incorrect because they either describe requirements for larger vessels (A and C) or a flare-up light, which is not an anchor light (B).
