Question 29 TV02 - Towing Vessels - Great Lakes and Inland

The Correct Answer is A. ### Why Option A ("2") is Correct This question is based on the U.S. Inland Navigation Rules (33 CFR Subchapter E). The rules governing anchor lights are found in Rule 30 (Anchored Vessels and Vessels Aground). Rule 30(a)(ii) states: "A vessel of 50 meters or more in length shall exhibit: (1) An after anchor light or all-round light in the after part of the vessel at a height lower than the forward anchor light; and (2) A forward anchor light or all-round light." Since the barge is **more than 50 meters long**, it is required to show **two** white anchor lights (one forward and one aft) when anchored, regardless of whether it is in a "special anchorage area" or not, unless that area is designated for smaller vessels where only one light is required. However, the rule explicitly requires two lights for vessels of this length. (Note on "special anchorage area": Rule 30(g) provides an exception that vessels less than 20 meters long, or barges, canal boats, or scows may not be required to show lights in a special anchorage area, but **only if the Secretary of Transportation designates that specific area as such AND exempts the specific class of vessel.** The core requirement for a vessel over 50 meters remains two lights unless specifically exempted, and length typically dictates the requirement for two lights.) ### Why Other Options Are Incorrect * **B) 1:** A single all-round white light is only appropriate for vessels less than 50 meters in length (Rule 30(a)(i)). Since the barge is more than 50 meters, one light is insufficient. * **C) 3:** There is no standard requirement under the Inland Rules for an anchored vessel to display three white anchor lights. * **D) None:** While Rule 30(g) allows the Secretary to waive lights for certain small vessels or barges in special anchorage areas, this specific exemption generally applies to vessels less than 20 meters or uninspected barges. A barge more than 50 meters long is typically required to display the full set of anchor lights to ensure safety, even in a special anchorage area, unless specifically designated otherwise. The primary rule based on length (Rule 30(a)(ii)) mandates two lights.
