Question 4227 Deck General

The correct answer is A) reverse starboard engine, apply right rudder. When a twin-screw vessel is making headway with both engines turning ahead, reversing the starboard engine while applying right rudder will cause the vessel to turn more readily to starboard. This is because the reduced thrust on the starboard side, combined with the right rudder, will create a yawing moment that will make the vessel turn more quickly to starboard. The other options are incorrect because reversing the port engine (B and C) or having the rudder amidships (C and D) will not create the same yawing moment to turn the vessel as effectively to starboard.
