Question 2 AB01 - Able Seafarer

The Correct Answer is C ### Explanation for C (special flashing light) Option C is correct because this question describes a scenario common under the U.S. Inland Navigation Rules (33 CFR 84.23(d)). The "special flashing light" is a yellow light flashing at 50 to 70 times per minute, visible over an arc of 225 degrees forward. This light is **required to be shown at the head (bow) of a vessel or vessels being pushed ahead** when operating on U.S. Inland Waters. If Vessel B is an inland towing vessel (tug) pushing a barge ahead, the front end of that barge must exhibit the special flashing light. Since Vessel A is meeting Vessel B head-on (or nearly head-on, passing 1/4 mile apart), the special flashing light on the head of the tow is one of the primary lights Vessel A will see, identifying the presence and forward extent of the tow. ### Explanation for Why Other Options Are Incorrect **A) red sidelight** While Vessel B will display a red sidelight (port side) and a green sidelight (starboard side), the question asks for *one* of the lights you will see. If Vessel A is approaching Vessel B, the vessel may initially see both sidelights and the masthead lights. However, the special flashing light is the unique and specific identifying light for this type of Inland pushing operation, making it the most distinctive required answer in this context. Furthermore, depending on the passing agreement (e.g., port-to-port), only the green sidelight might be clearly visible. **B) yellow towing light** The yellow towing light (also known as the stern light when shown above the white stern light) is visible only from the stern (135 degrees). Since Vessel A and Vessel B are **meeting** (approaching each other), Vessel A is viewing Vessel B's forward aspect. Therefore, Vessel A cannot see the yellow towing light. **D) All of the above** Since option B (yellow towing light) is incorrect, this option cannot be correct.
