Diagram for question 244
AI Explanation
The correct answer is D) Vessel "A" must keep clear of vessel "B". This is based on the International Regulations for Preventing Collisions at Sea (COLREGS), which govern the rules of the road for vessels at sea. In a crossing situation, the vessel on the right (starboard) side has the right of way, and the vessel on the left (port) side must keep clear. In this case, vessel "B" is on the starboard side of vessel "A", so vessel "A" must take action to avoid a collision by altering course or speed to pass behind vessel "B". The other options are incorrect because they do not properly apply the COLREGS rules for a crossing situation. Vessel "B" should not pass astern of vessel "A", the vessels should not pass starboard-to-starboard, and vessel "B" does not need to alter course to the right, as vessel "A" is the one required to keep clear.
