Diagram for question 99
AI Explanation
The correct answer is C) not impede the passage of vessel "B". In this scenario, vessel "B" is a power-driven vessel that can only safely navigate within the narrow channel. The International Regulations for Preventing Collisions at Sea (COLREGS) state that a sailing vessel (vessel "A") must not impede the safe passage of a power-driven vessel (vessel "B") in a narrow channel. Vessel "B" has sounded the danger signal, indicating it is in a constrained situation and requires the sailing vessel to take action to avoid impeding its passage. The other answer choices are incorrect because: A) sounding the danger signal is the responsibility of vessel "B", not vessel "A"; B) the sailing vessel does not have the right of way in this situation; and D) maintaining course and speed would impede the passage of vessel "B", which is not allowed.
