What effect will bank suction have on a vessel?

A the bow swings away from the bank
B the stern swings towards the bank
C the stern swings away from the bank
D the bow swings towards the bank
AI Explanation

The correct answer is B) the stern swings towards the bank. When a vessel is operating in close proximity to a bank or shoreline, the phenomenon of "bank suction" can occur. Bank suction is caused by the displacement of water between the vessel and the bank, which creates a lower pressure area that pulls the stern of the vessel towards the bank. This effect is most pronounced when the vessel is traveling parallel to the bank at a relatively high speed. The other options are incorrect because A) the bow swinging away from the bank is the opposite of the bank suction effect, C) the stern swinging away from the bank is also incorrect, and D) the bow swinging towards the bank does not accurately describe the bank suction phenomenon.
