Question 668 Rules of the Road

The correct answer is A) it is a fishing vessel. The lights shown in illustration D082RR indicate that the vessel is exhibiting the required navigation lights for a fishing vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a fishing vessel underway must display a masthead light, sidelights, and a stern light, which is the configuration shown in the illustration. The other answer choices are incorrect because a pilot boat on duty would not exhibit these specific lights, a sailing vessel would have different light configurations, and a trawling vessel is a type of fishing vessel, so the correct answer is that the vessel is a fishing vessel.
