Question 32 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is A. ### Why Option A ("not under command") is correct: The illustration D084RR depicts a vessel showing two specific lights: 1. **Two vertical all-round red lights (in a line).** This specific signal is prescribed by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 27(b), to indicate a vessel that is **"not under command" (NUC)**. These lights replace the masthead, sidelights, and sternlight required for a power-driven vessel underway, though the sidelights and sternlight must still be shown if the vessel is making way through the water. The primary defining characteristic of the illustration is the pair of vertical all-round red lights, which unambiguously signifies NUC status. ### Why other options are incorrect: * **B) showing improper lights:** While the lights *could* be improper if shown by a vessel other than one NUC, the specific combination of two vertical all-round red lights is a distinct, recognized signal in COLREGs. Therefore, the vessel is exhibiting a standard signal, meaning the lights themselves are proper for the specific situation they are communicating (NUC). * **C) dredging:** A vessel engaged in dredging or underwater operations (restricted in its ability to maneuver, or RAM) is indicated by three vertical all-round lights: Red-White-Red. The illustration shows only two red lights, thus ruling out dredging operations (Rule 27(d)). * **D) towing:** A vessel engaged in towing (if the length of the tow is less than 200 meters) would typically show two vertical masthead lights (in addition to sidelights and sternlight). If the tow exceeds 200 meters, it would show three vertical masthead lights (Rule 24). Neither of these configurations involves two vertical all-round red lights.
