Question 27 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is C ### Why Option C (sidelights and two towing lights) is Correct This scenario describes the lighting requirements for a power-driven vessel engaged in pushing ahead or towing alongside *specifically* on the Western Rivers (above the Huey P. Long Bridge), which are governed by the **Inland Navigation Rules** (specifically Rule 24(g) and Rule 24(h), read in conjunction with the special provisions for Western Rivers). Under the Inland Rules, a pushing vessel or vessel towing alongside on the Western Rivers is considered an "integrated tow" and is generally required to show specific lights: 1. **Sidelights:** Required for any vessel underway. 2. **Two towing lights:** These lights (yellow, stacked vertically) replace the stern light and masthead lights traditionally shown by a pushing vessel *on the Western Rivers*. These two towing lights identify the vessel as a towboat operating in this specific geographical area. *(Note: While Inland Rule 24(g) for a pushing vessel generally requires masthead lights, sidelights, and two towing lights, Rule 24(h) provides the special exemption for Western Rivers towboats, allowing them to exhibit only sidelights and two towing lights.)* ### Why the Other Options Are Incorrect **A) one masthead light, sidelights, and stern light** * **Incorrect:** This configuration is typically for a vessel pushing ahead *outside* the Western Rivers or for a smaller vessel of limited length engaged in general towing. It does not meet the specific Western Rivers requirement for the two vertical yellow towing lights. **B) two masthead lights, sidelights, and stern light** * **Incorrect:** Two masthead lights are shown by a conventional towing vessel (towing astern) when the tow length exceeds 200 meters, or by larger pushing vessels outside the special Western Rivers provisions. It fails to include the mandatory two vertical yellow towing lights used on the Western Rivers. Furthermore, a pushing vessel generally does not show a stern light (it is replaced by the towing lights). **D) two masthead lights, sidelights, and two towing lights** * **Incorrect:** While this configuration is technically required for a vessel pushing ahead on the *Great Lakes* (Inland Rule 24(g)), the special exception for the Western Rivers (Inland Rule 24(h)) allows the vessel to omit the masthead lights, simplifying the configuration to only the sidelights and the two towing lights.
