Question 49 RVR01 - Master of Unlimited Tonnage

The Correct Answer is A ### Explanation for Option A (Correct) Option A is correct based on U.S. Inland Rules of the Road, specifically Rule 24(g) and Rule 24(h), regarding vessels being pushed ahead in a flotilla that is not a composite unit. 1. **Sidelights:** A barge (being an inconspicuous, partly submerged vessel) when being pushed ahead must exhibit the proper navigating lights, which include **sidelights** (red on port, green on starboard) to show its direction of movement to passing vessels (Rule 24(h)). 2. **Special Flashing Light:** Inland Rule 24(g) mandates that an inconspicuous, partly submerged vessel or object being pushed ahead, *other than those forming part of a composite unit*, shall exhibit an **all-round special flashing light** at the forward end. This light is intended to clearly mark the leading edge of the tow being pushed by the propelling vessel, which itself will be exhibiting towing lights. Therefore, the required combination is Sidelights and a special flashing light. ### Explanation of 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 vessel doing the towing—the pushing vessel, in this case) or a standard **stern light**. It is the pushing vessel that shows the masthead lights, towing lights, and stern light. The barge uses the special flashing light instead of a stern light at the leading end. **C) Sidelights, a special flashing light, and a stern light** * **Incorrect:** While sidelights and the special flashing light are required, the barge does not exhibit a standard **stern light** (a white light placed aft showing 135 degrees). The special flashing light replaces the need for an additional stern light on the forward part of the tow. **D) Sidelights and a stern light** * **Incorrect:** This option omits the required **special flashing light** (Rule 24(g)), which is mandatory for inconspicuous tows being pushed ahead on inland waters. It also incorrectly specifies a standard **stern light** rather than the special flashing light for marking the lead end of the tow.
