BOTH INTERNATIONAL & INLAND Which identification lights are required to be exhibited on a vessel engaged in trawling?

Correct Answer: Option C — a green light over a white light

Rule 26(a)(i) establishes that a vessel engaged in trawling must exhibit two all-round lights in a vertical line, with the green light positioned above the white light. This specific vertical arrangement is mandatory for all vessels trawling, whether in international or inland waters.
