BOTH INTERNATIONAL & INLAND Which vessel would exhibit the lights shown in illustration D056RR below?
AI Explanation
The correct answer is B) a vessel dredging while underway.
The lights shown in illustration D056RR represent the required navigation lights for a vessel engaged in dredging or underwater operations while underway. This is specified in the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules.
The other answer choices do not match the light configuration shown in the illustration. A vessel fishing at anchor would exhibit different lights, a vessel transferring dangerous cargo would have additional signals, and a vessel restricted in maneuverability would have a different arrangement of navigation lights.
