Question 49 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is A ### Explanation for Option A (Correct) Option A is correct based on U.S. Inland Rules, specifically Rule 24(g) and Rule 24(h), regarding the lighting of vessels being pushed ahead in a tow (but not forming part of a composite unit). * **Sidelights (Red and Green):** These are required for any vessel being towed (pushed or pulled) to indicate its presence and direction to approaching vessels. * **Special Flashing Light (Yellow):** Inland Rule 24(g) specifically mandates that a barge or barges being pushed ahead, not being part of a composite unit, must exhibit a special flashing light at the forward end. This light is a yellow light flashing at a frequency of 50 to 70 flashes per minute, intended to clearly mark the bow of the tow. Therefore, a barge being pushed ahead requires sidelights and the special flashing light. ### Why Other Options Are Incorrect **B) Sidelights, a towing light, and a stern light** * **Incorrect:** A barge being pushed ahead does not exhibit a **towing light** (which is reserved for the pushing vessel/tug). It also generally does not exhibit a **stern light** when being pushed ahead, as the stern is typically obscured or marked by the lights of the vessel pushing it. The required identifying light forward is the special flashing light, not a towing light or a stern light. **C) Sidelights, a special flashing light, and a stern light** * **Incorrect:** While the sidelights and the special flashing light are correct, the barge does not typically exhibit a **stern light** when being pushed ahead. The light required forward is the special flashing light, which replaces the need for an all-round light or a masthead light in this specific configuration. **D) Sidelights and a stern light** * **Incorrect:** This option is missing the critical light required under Inland Rules: the **special flashing light** at the head of the tow. Furthermore, the barge being pushed ahead does not typically exhibit a stern light.
