INTERNATIONAL ONLY You see the lights shown in illustration D066RR below. What do these lights indicate ?
AI Explanation
The correct answer is A) Vessel towing a barge alongside.
The lights shown in illustration D066RR indicate a vessel towing a barge alongside. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel towing a barge alongside is required to display the same lights as a power-driven vessel, which includes the all-round white masthead light, sidelights, and a sternlight. The configuration of the lights shown in the illustration matches this requirement for a vessel towing a barge alongside.
The other options are incorrect because they do not match the lighting configuration displayed in the illustration. A dredge working at anchor would typically display anchor lights rather than the full set of navigation lights shown. A vessel pushing a barge ahead would have a different lighting arrangement, and a pilot vessel with a launch alongside would also have a different set of lights.
