Question 18 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is A **Explanation for Option A (A vessel constrained by her draft):** Rule 28 of the COLREGs (International Regulations for Preventing Collisions at Sea) specifies the lights for power-driven vessels constrained by their draft. A vessel constrained by her draft must display, in addition to the lights prescribed for a power-driven vessel underway (masthead lights, sidelights, and sternlight), **three all-round red lights in a vertical line** where they can best be seen. Therefore, sighting three vertical red lights on a vessel dead ahead at night identifies that vessel as constrained by her draft. **Explanation of Incorrect Options:** * **B) A vessel moored over a wreck:** A vessel engaged in diving or underwater operations (which may include mooring over a wreck for salvage or inspection) displays three all-round lights in a vertical line: **red, white, red**. This differs from the three all-round red lights displayed by a vessel constrained by her draft. * **C) A vessel aground:** A vessel aground must display the lights prescribed for an anchored vessel (forward all-round white light, or two all-round white lights if over 50 meters), and in addition, where they can best be seen, **two all-round red lights in a vertical line.** This is two red lights, not three. * **D) A vessel dredging:** A vessel engaged in dredging (a type of vessel restricted in her ability to maneuver) displays the standard lights for a vessel restricted in her ability to maneuver, plus additional lights indicating the side on which obstruction exists and the side on which another vessel may pass. The primary lights for restricted maneuverability are **three all-round lights in a vertical line: red, white, red.** This differs from three all-round red lights.
