Question 29 GLI04 - Mate of LT 500-1600 GRT

The Correct Answer is A. **Explanation for A (2):** The question specifies a vessel operating **INLAND ONLY** (under the Inland Rules of the Road), which is a barge (a non-self-propelled vessel), and is "more than 50 meters long." According to the Inland Navigation Rules (specifically Rule 30 - Anchored Vessels and Vessels Aground), a non-self-propelled vessel (like a barge) that is **50 meters or more in length** is required to exhibit two white anchor lights: 1. One white light forward, or near the bow. 2. One white light aft, or near the stern. These lights must be visible all around the horizon. The designation as a "special anchorage area" (approved by the Secretary) does not negate the standard requirement for showing anchor lights based on the vessel's length unless the vessel is under 20 meters long, which this barge is not. Therefore, two anchor lights are required. **Explanation for why other options are incorrect:** * **B) 1:** A single anchor light is required only for vessels less than 50 meters in length (Rule 30(a)(i)). Since the barge is "more than 50 meters long," one light is insufficient. * **C) 3:** There is no requirement under either Inland or International Rules for a conventionally anchored vessel to display three white anchor lights based on length alone. * **D) None:** All vessels (except those in "special anchorage areas" under 20 meters in length, or very small unlighted barges that are pushed or towed) are required to display anchor lights. Since this barge is over 50 meters, it absolutely requires anchor lights.
