Question 29 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is A ### Explanation for Option A (2) The correct answer is **2**. This is governed by the US Inland Navigation Rules (specifically Rule 30). 1. **Size Requirement (Rule 30(b)):** A vessel 50 meters or more in length, when at anchor, is required to exhibit two all-around white anchor lights: one forward, and one aft, at a level lower than the forward light. Since the barge is more than 50 meters long, the requirement is generally two lights. 2. **Special Anchorage Area (Rule 30(g)):** Although the vessel is anchored in a "Secretary approved special anchorage area," the exemption provided by this rule applies *only* to vessels less than 20 meters in length. Since the barge is more than 50 meters long, it does not qualify for the exemption and must display the standard lights required for its size. Therefore, a barge over 50 meters must show **two** white anchor lights. ### Explanation for the Other Options **B) 1:** This is incorrect. Only one white anchor light (forward) is required for vessels less than 50 meters in length (unless they are very small and exempt). Since the barge is over 50 meters, it must display two. **C) 3:** This is incorrect. There is no standard requirement for an anchored vessel to show three white anchor lights under Rule 30. **D) None:** This is incorrect. While "special anchorage areas" do allow small vessels (less than 20 meters) to show no anchor lights (Rule 30(g)), this specific barge is over 50 meters long and thus must comply with the general lighting requirements for large anchored vessels.
