Question 26 UFV02 - Mate - Uninspected Fishing Vessels

The Correct Answer is D **Explanation for Option D (Correct):** Option D is correct based on the specific rules for lighting on the Great Lakes, found in the Inland Rules (33 CFR Part 89, Subpart B, Rule 23 - Power-driven vessels underway). Specifically, the Inland Great Lakes Annex (33 CFR Part 90) provides exceptions for smaller vessels. Rule 23(d)(i) of the Inland Rules, as applied to the Great Lakes, states that a power-driven vessel of less than 12 meters in length: > "...may carry the all-round white light prescribed in paragraph (b) of this Rule in lieu of the second masthead light and stern light prescribed in paragraph (a) of this Rule." This provision allows small power-driven vessels (under 12 meters) operating on the Great Lakes (Inland Only) to simplify their lighting configuration by using a single all-round white light instead of the separate second masthead light and stern light required for larger vessels. *** **Explanation of Incorrect Options:** **A) Great Lakes vessels are exempted from the requirement to show yellow towing lights.** This is incorrect. The requirement to show yellow towing lights (specifically, two vertically aligned yellow lights above the white masthead or stern light) applies to vessels engaged in towing (Rule 24). There is no blanket exemption from this requirement for Great Lakes vessels; they must follow the standard towing light requirements when applicable. **B) Sidelights for vessels over 50 meters are required to have only a two-mile range of visibility.** This is incorrect. The visibility requirements (Rule 22) mandate that the sidelights for power-driven vessels 50 meters or more in length must have a minimum range of **3 miles** (not 2 miles). The 2-mile range applies only to the sidelights of vessels between 20 meters and 50 meters in length. **C) The showing of a forward masthead light is optional for vessels under 150 meters.** This is incorrect. Rule 23 requires all power-driven vessels underway to show a forward masthead light, regardless of length (except for very small vessels under 12 meters which may substitute the all-round white light). The requirement is mandatory, not optional, for vessels up to 150 meters. Vessels under 50 meters are generally only required to show the single forward masthead light (and stern light/sidelights), but they are *not* permitted to omit it.
