Question 30 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is C **Explanation for Option C (sailing vessel):** The illustration D080RR shows a vessel displaying the **red sidelight** (port side) and the **green sidelight** (starboard side), along with the **sternlight** (white). These lights are being viewed from directly ahead (or slightly off the bow) of the observed vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS) Rule 23, 24, and 25 (and corresponding Inland Rules), a power-driven vessel underway must show masthead light(s), sidelights, and a sternlight. However, **Rule 25 (Sailing Vessels Underway and Vessels Under Oars)** states that a sailing vessel underway must exhibit sidelights and a sternlight. Furthermore, if a sailing vessel is 20 meters or more in length, the sidelights may be combined in one lantern carried at or near the top of the mast. Since the illustration shows only sidelights and a sternlight (and no masthead light), the vessel is positively identified as a **sailing vessel** underway. **Explanation for why other options are incorrect:** * **A) vessel on pilotage duty:** A vessel engaged in pilotage duty (Rule 29) must show, in addition to the standard sidelights and sternlight, two all-round lights in a vertical line: an **all-round white light** over an **all-round red light**. These identifying lights are missing from the illustration. * **B) law enforcement vessel:** While specific "law enforcement" lights vary by local Inland rules (often flashing blue), if the vessel is a power-driven vessel, it must display the standard power-driven vessel lights, including a **masthead light**. If the vessel is also restricted in its ability to maneuver (COLREGS Rule 27), it would display three all-round lights (Red-White-Red). The lights shown do not match either requirement. * **D) vessel engaged in fishing:** A vessel engaged in fishing (Rule 26) must display two all-round lights in a vertical line: an **all-round red light** over an **all-round white light**. If the vessel is making way, it must also show sidelights and a sternlight. The essential identifying all-round lights (Red over White) are missing from the illustration.
