Question 26 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is D --- ### Explanation of Why Option D is Correct **D) An all-round white light may be carried in lieu of the second masthead light and stern light.** This statement is correct based on specific allowances within the U.S. Inland Navigational Rules, which govern the Great Lakes: 1. **Small Vessels (Rule 23(c)):** Power-driven vessels less than 12 meters in length may carry an all-round white light and sidelights in lieu of the regular configuration (masthead light, stern light, sidelights). The all-round white light effectively replaces both the masthead light and the stern light. 2. **Towing Vessels on the Great Lakes (33 CFR 89.15(c)):** Specifically for vessels under 50 meters in length when engaged in towing on the Great Lakes, the vessel is permitted to carry an all-round white light in lieu of the after masthead light and the stern light. Because these configurations are explicitly permitted under the rules applicable to the Great Lakes, the statement is true. --- ### Explanation of Why Other Options Are Incorrect **A) Great Lakes vessels are exempted from the requirement to show yellow towing lights.** This is incorrect. Under the U.S. Inland Rules (Rule 24(a)(iii)), a vessel engaged in towing must show a yellow towing light situated vertically above the stern light. This rule applies to vessels navigating on the Great Lakes. **B) Sidelights for vessels over 50 meters are required to have only a two-mile range of visibility.** This is incorrect. Under Rule 22 (Visibility of Lights), the sidelights for vessels $\mathbf{50}$ **meters or more** in length must have a minimum visibility range of **3 miles**. The two-mile range applies to vessels between 12 meters and 50 meters in length. **C) The showing of a forward masthead light is optional for vessels under 150 meters.** This is incorrect. The forward masthead light is mandatory for *all* power-driven vessels underway (Rule 23(a)(i)). The only masthead light that is optional for vessels under 50 meters is the **after** masthead light (the second one). The forward masthead light is never optional for a vessel underway (except for specific small vessel exemptions that substitute it with an all-round light, as noted in option D).
