Question 4209 Deck General
70% to passYou are landing a single-screw vessel with a right-handed propeller port side to a dock. As you approach the dock, you back down on your engine with rudder amidships. You would expect the vessel to _______________.
A
lose headway without swinging
B
swing its stern away from the dock
C
swing its stern towards the dock
D
drift away from the dock
AI Explanation
The correct answer is C) swing its stern towards the dock. When backing down on a single-screw vessel with a right-handed propeller while the rudder is amidships, the vessel will swing its stern towards the dock. This is due to the rotation of the right-handed propeller, which creates a sideways thrust that pushes the stern towards the dock as the vessel loses headway. The other options are incorrect because: A) the vessel will lose headway and swing, not just lose headway; B) the stern will swing towards the dock, not away; and D) the vessel will drift towards the dock, not away.
