Question 49 TV03 - Towing Vessels - Western Rivers

The Correct Answer is A ### Explanation for Option A (Correct) Option A is correct based on the **Inland Rules of Navigation (33 CFR Subchapter E)**, specifically addressing the lights required for barges being pushed ahead on U.S. inland waters when they are **not** part of a composite unit (a rigid tow). 1. **Sidelights:** A barge being pushed ahead is considered a vessel underway and must exhibit the required navigation lights visible from the sides, as per Rule 23(a)(ii) and the definition of a power-driven vessel when being pushed. 2. **Special Flashing Light:** According to **Inland Rule 24(g)**, a vessel or object being towed (specifically, a barge being pushed ahead) must exhibit an **all-round special flashing light** at the forward end. This light must be yellow and flash at a rate of 50 to 70 flashes per minute. This distinct light serves to clearly identify the lead end of the tow, aiding safe navigation, especially at night. Therefore, the combination of sidelights and the special flashing light fulfills the requirements for a non-composite barge being pushed ahead on inland waters. ### Explanation of Incorrect Options **B) Sidelights, a towing light, and a stern light** * **Incorrect:** A **towing light** (an extra yellow masthead light above the stern light) is required on the pushing vessel (the towing vessel), not the barge being pushed ahead. A **stern light** is generally not required on the barge being pushed ahead (which is covered by the pushing vessel's lights or the special flashing light marking the forward end). **C) Sidelights, a special flashing light, and a stern light** * **Incorrect:** While sidelights and the special flashing light are required (per Option A), a standard **stern light** (white light facing aft) is **not** mandated for the pushed barge itself under Inland Rule 24(g). The required lights are limited to the sidelights and the special flashing light. **D) Sidelights and a stern light** * **Incorrect:** This combination lacks the mandatory **special flashing light** (Inland Rule 24(g)), which is the critical identifying light for a tow being pushed ahead on inland waters.
