Question 29 GLI01 - Master-Unlimited Tonnage

The Correct Answer is A. **Explanation for Option A (2) being correct:** The scenario specifies a barge anchored in an **INLAND ONLY** area. The barge is more than 50 meters long. According to the U.S. Inland Navigation Rules (specifically 30(a) and relevant Annex V concerning Inland application): 1. **General Requirement:** An anchored vessel must display anchor lights. 2. **Vessel Length (>50 meters):** A vessel (including a barge) 50 meters or more in length is required to display: * An anchor light (white) forward. * An anchor light (white) at or near the stern, at a level lower than the forward light. Therefore, an anchored barge exceeding 50 meters in length must show **two** white anchor lights. The classification of the location as a "Secretary approved 'special anchorage area'" does not waive the requirement for vessels over 50 meters to display lights under the Inland Rules, as Rule 30(b) only grants an exemption to vessels **less than 20 meters** anchored in such areas. **Explanation for why other options are incorrect:** * **Option B (1):** This would be correct only if the vessel were less than 50 meters long (or if the Inland Rules were completely disregarded). Since the barge is explicitly stated as being more than 50 meters long, it requires two lights. * **Option C (3):** There is no standard requirement under either the International or Inland Rules for an anchored vessel of any length to display three white anchor lights. * **Option D (None):** Displaying no lights would be incorrect and illegal. The exemption under Rule 30(b) for anchored vessels in a "special anchorage area" only applies to vessels **less than 20 meters** in length. Since the barge is more than 50 meters long, it must display the required lights.
