Question 49 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is A ### 1. Why Option A ("Sidelights and a special flashing light") is Correct This question pertains specifically to vessels operating under **Inland Rules** (U.S. Inland Waters) and involves a barge (an inconspicuous, partly submerged vessel or object) being pushed ahead, but **not** forming part of a rigid composite unit (where the connection is essentially like a single self-propelled vessel). Under Inland Rules: * **Rule 24(a)(i)** addresses the lights required for a vessel pushing another ahead when they are not a composite unit. The barge being pushed ahead must show **sidelights**. * **Rule 24(g) (Inland Annex V)** specifies the lights for barges being pushed ahead in general: * The headmost barge must display **sidelights**. * The headmost barge must display a **special flashing light** (an all-round yellow light flashing 50-70 times per minute) at or near its forward end. Therefore, the barge requires **sidelights** and the **special flashing light**. ### 2. Why Other Options Are Incorrect **B) Sidelights, a towing light, and a stern light** * **Incorrect:** A barge being pushed ahead does not display a towing light (which is an amber masthead light displayed above the stern light, used only by the pushing vessel—the towing vessel—in this scenario). It also does not display a stern light when being pushed ahead (it only displays a stern light if being towed astern or being pushed alongside). **C) Sidelights, a special flashing light, and a stern light** * **Incorrect:** While sidelights and the special flashing light are required, a barge being pushed ahead (not being towed astern or alongside) does not display a stern light. **D) Sidelights and a stern light** * **Incorrect:** This combination lacks the mandatory **special flashing light** required by Inland Rule 24(g) for the headmost barge being pushed ahead. It also incorrectly includes a stern light.
