A vessel engaged in trawling will show identification lights of which configuration?

A vessel engaged in trawling will show identification lights of which configuration?

• A. Green over red
• B. A green light over a white light
• C. White over green
• D. Red over green

Answer: (B)

The key idea is the special night signaling for fishing vessels. Under the rules, a vessel engaged in trawling must show two all-round lights in a vertical line near the bow: the upper light is green and the lower light is white. This combination identifies the vessel as actively fishing with gear, helping other vessels know its operating status and avoid complex entanglements or collisions. These lights are in addition to the standard navigation lights, and the green-over-white arrangement is the specific signal for trawling. The other color orders do not match the regulation for trawling, so they would not convey the same meaning.
