Question 29

The Correct Answer is A. ### Why Option A ("2") is Correct This question refers to the specific requirements of the **Inland Rules** (33 CFR Subchapter E). The relevant regulation is Rule 30(a), which details the lights required for anchored vessels. * **Rule 30(a)(ii)** states that a vessel **less than 50 meters in length** shall exhibit one all-around white light forward. * **Rule 30(a)(i)** states that a vessel **50 meters or more in length** shall exhibit: * An all-round white light forward; and * An all-round white light or lantern at or near the stern and at a lower level than the forward light. Since the barge is **more than 50 meters long**, it is required to show **two** all-around white anchor lights (one forward and one aft) under the Inland Rules, regardless of whether it is in a "special anchorage area" or not (the special anchorage designation only potentially exempts vessels from sounding fog signals, not showing lights). ### Why Other Options Are Incorrect * **Option B ("1") is incorrect** because one anchor light is only required for vessels **less than 50 meters** in length under the Inland Rules. Since the barge is more than 50 meters long, one light is insufficient. * **Option C ("3") is incorrect** because the Inland Rules (Rule 30) only mandate a maximum of two all-around white anchor lights (forward and aft) for vessels of this length. * **Option D ("None") is incorrect** because only small vessels (less than 20 meters) anchored in a "special anchorage area" are exempted from showing anchor lights, provided they do not obstruct a navigable channel. A barge more than 50 meters long is required to display anchor lights under all circumstances, even in a special anchorage area.
