Question 27 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is C ### Why Option C (sidelights and two towing lights) is correct: The question specifies a power-driven vessel that is **pushing ahead or towing alongside** on the **Western Rivers** (specifically above the Huey P. Long Bridge on the Mississippi River at mile 106.1). This means the vessel is operating under the **Inland Rules** and is subject to the specific rules for vessels pushing ahead or towing alongside on the Western Rivers, which are codified under Rule 24(g) of the Inland Navigation Rules. Rule 24(g) states: > A power-driven vessel when pushing ahead or towing alongside, except as required by paragraphs (a) and (i) of this Rule, shall exhibit the **sidelights** and **two towing lights** in a vertical line. The two towing lights replace the traditional stern light(s) and any masthead lights normally associated with towing, simplifying the required configuration for these specific operations on the Western Rivers. ### Why the other options are incorrect: * **A) one masthead light, sidelights, and stern light:** This configuration is incorrect for towing operations. Towing requires at least two or three masthead lights (depending on the length of the tow) and two towing lights (if operating under standard Inland/International Rules) or specific lights for the Western Rivers (two towing lights only). Furthermore, stern lights are generally replaced by towing lights when towing. * **B) two masthead lights, sidelights, and stern light:** This is the standard configuration for a vessel **under 50 meters in length** engaged in a tow of **200 meters or less** under standard Inland/International rules, but it is **not** the rule for towing/pushing alongside specifically on the Western Rivers. On the Western Rivers, the two towing lights replace the masthead lights and stern light for pushing ahead/towing alongside operations (Rule 24(g)). * **D) two masthead lights, sidelights, and two towing lights:** This configuration combines the standard towing lights (two masthead lights and two towing lights) used elsewhere with the Western Rivers towing lights (two towing lights). The specific rule for pushing ahead/towing alongside on the Western Rivers (Rule 24(g)) only requires the sidelights and the two towing lights; it explicitly excludes the use of masthead lights.
