Question 10 Rules of the Road

The correct answer is C) Need not show any lights. According to the U.S. Coast Guard Navigation Rules, vessels less than 20 meters in length that are at anchor in a "special anchorage area designated by the Secretary" are not required to display anchor lights at night. This is because the Secretary has deemed these designated areas to be sufficiently safe for vessels to anchor without the need for anchor lights, as other vessels are expected to navigate with caution in these areas. The other answer choices are incorrect because A) requires a single white light, B) requires a light only on the approach of another vessel, and D) requires two white lights, all of which are not necessary for vessels less than 20 meters in length anchored in a designated special anchorage area.
