Question 887 Rules of the Road

The correct answer is B) Not impede the passage of vessel "B". This is the correct answer because the International Regulations for Preventing Collisions at Sea (COLREGS) state that a vessel that is less maneuverable, such as the large tanker "B", has the right-of-way in a narrow channel. As the stand-on vessel, you should take action to not impede the passage of the larger, less maneuverable vessel "B" by maintaining course and speed. The other answer choices are incorrect because: A) Maintaining course and speed would impede the passage of the larger vessel, which is not allowed. C) Not answering the whistle signal would be improper communication. D) Sounding a whistle signal is not the appropriate action in this situation.
