Question 629 Rules of the Road

The correct answer is C) a pilot vessel at anchor. The reason this is the correct answer is that the lights shown in illustration D061RR depict the lights required for a vessel at anchor, as per the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules. A pilot vessel at anchor would be required to display these lights, which include an all-around white light at the masthead to indicate the vessel is at anchor. The other answer choices are incorrect because a fishing vessel aground (A) would not be displaying anchor lights, a fishing vessel hauling her nets (B) would have different light requirements, and a fishing vessel (D) would not be displaying anchor lights unless it was at anchor.
