BOTH INTERNATIONAL & INLAND Vessel "A" is overtaking vessel "B" as shown in illustration D017RR below, and will pass without changing course. Vessel "B" is an air-cushion vessel operating in the non-displacement mode. Which light will vessel "A" observe from vessel "B"?

Diagram for question 751
AI Explanation
The correct answer is C) flashing yellow light. According to the International Regulations for Preventing Collisions at Sea (COLREGS), an air-cushion vessel operating in the non-displacement mode is required to exhibit a flashing yellow light when overtaken by another vessel. This is specified in Rule 18(f) of the COLREGS. The other answer choices are incorrect because a green light is not a recognized signal for an air-cushion vessel, a flashing red light would indicate a vessel not under command, and a flashing white light is not the proper signal for an overtaking situation involving an air-cushion vessel.
