Question 3877Deck General70% to pass
A twin-screw ship going ahead on the starboard screw only tends to move _______________.
AI Explanation
The correct answer is B) to port.
When a twin-screw ship is going ahead on the starboard screw only, the forward thrust from the starboard propeller will cause the stern to swing to port, making the ship move to port. This is due to the asymmetric thrust created by the single operating propeller, which produces a turning moment that causes the ship to turn towards the side with the active propeller.
The other answer choices are incorrect because: A) the ship would not move to starboard, as the asymmetric thrust would cause it to turn to port; C) the ship would not move from side to side, but rather in a turning motion to port; and D) the ship would not move in a straight line, as the asymmetric thrust would cause it to turn.
