Diagram for question 982
AI Explanation
The correct answer is D) None of the above statements is TRUE. The reason this is the correct answer is that in a narrow channel with restricted visibility, as described in the scenario, the appropriate whistle signals are not one short blast, two short blasts, or any combination thereof. Instead, the International Regulations for Preventing Collisions at Sea (COLREGS) Rule 34(e) states that in this situation, both vessels should sound the danger signal, which is five or more short and rapid blasts on the whistle. This alerts the other vessel to the restricted visibility and potential danger of the situation, prompting both vessels to take appropriate action to avoid a collision.
