BOTH INTERNATIONAL & INLAND Which vessel would exhibit sidelights when underway and not making way?

A A vessel engaged in fishing
B A power-driven vessel
C A vessel engaged in dredging
D A vessel not under command
AI Explanation

The correct answer is B) A power-driven vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a power-driven vessel underway and not making way (i.e., drifting or dead in the water) must exhibit sidelights, even though it is not actively moving. This is specified in Rule 23(a) of the COLREGS. The other options are incorrect because: A) Fishing vessels have different light requirements, C) Dredging vessels are considered "vessels restricted in their ability to maneuver" with different light requirements, and D) Vessels not under command have different light requirements as well.
