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?

Correct Answer: Option B — Compensate with right rudder.

Operating ahead on the starboard engine alone creates an unbalanced turning moment pushing the bow to port. Applying right rudder utilizes water flow across the rudder blade to create an opposing transverse force, keeping the vessel moving straight ahead.
