90% to pass

INTERNATIONAL ONLY Which of the following does NOT exhibit a yellow light?

A Purse seiners
B Towing vessels pushing ahead
C Air cushion vessels in a non-displacement mode
D U.S. submarines
AI Explanation

The correct answer is B) Towing vessels pushing ahead. According to the International Regulations for Preventing Collisions at Sea (COLREGS), towing vessels pushing ahead are required to exhibit a yellow all-round light, not a yellow light. This is specified in Rule 24(c) of the COLREGS, which states that a vessel "being pushed ahead" must exhibit the same lights as the vessel being pushed. The other options are incorrect because: A) Purse seiners, C) Air cushion vessels in a non-displacement mode, and D) U.S. submarines are all required to exhibit a yellow light under the COLREGS.
