Question 602 Rules of the Road

The correct answer is C) pilot vessel less than 50 meters, underway and NOT engaged on pilotage duty. This is correct because the lights shown in illustration D045RR depict the navigation lights required for a power-driven vessel less than 50 meters in length that is underway, but not engaged in pilotage duty. The display of these specific lights, without any other lights, indicates the vessel is a pilot vessel that is not actively engaged in pilotage operations. The other answer choices are incorrect because they do not match the lighting configuration shown in the illustration. A vessel engaged in dredging, aground, or fishing would display different navigation light configurations.
