Question 3884 Deck General

The correct answer is C) It pulls the stern toward the bank. The effect known as "bank suction" occurs when a single-screw vessel is proceeding along a narrow channel. As the vessel moves forward, the rotating propeller creates a low-pressure area near the stern, which pulls the stern of the vessel toward the nearby bank. This can cause the stern to swing toward the bank, potentially leading to a dangerous situation if not properly managed. The other answer choices are incorrect because: A) the bow is pulled toward the bank, not pushed away; B) the entire vessel is not pushed away from the bank, only the stern is pulled toward it; and D) the vessel does not heel (tilt) toward the bank, but rather the stern is pulled toward it.
