Question 4225Deck General70% to pass
You are operating a twin-screw vessel and lose your port engine. You continue to operate on your starboard engine only. Which action would you take to move your vessel ahead in a straight line?
AI Explanation
The correct answer is B) Compensate with right rudder.
When operating a twin-screw vessel with only the starboard engine running, the vessel will naturally want to turn to port due to the asymmetrical thrust. To counteract this and maintain a straight course, the operator must apply right rudder to compensate and keep the vessel moving ahead in a straight line.
The other options are incorrect because: A) Applying left rudder would only exacerbate the turning to port, C) Keeping the rudder amidships would not provide the necessary compensation, and D) Surging the starboard engine alone would not be enough to overcome the asymmetrical thrust and keep the vessel straight.
