What effect does bank suction have upon the hull of a vessel in shallow water?

A the hull has a greater pressure on the land side of the bow
B the hull has a lesser pressure on the land side of the stern
C the hull has a lesser pressure on the land side of the bow
D the hull has a greater pressure on land side of the stern
AI Explanation

The correct answer is B) the hull has a lesser pressure on the land side of the stern. When a vessel travels in shallow water, the water flow around the hull can create an area of reduced pressure on the stern side of the vessel, known as bank suction. This reduced pressure on the stern side causes the vessel to be pulled towards the bank or shore, resulting in a greater pressure on the land side of the stern compared to the bow. The other options are incorrect because: A) the pressure would be greater on the bow, not the stern; C) the pressure would be greater on the bow, not the lesser on the bow; and D) the pressure would be greater on the stern, not the land side of the stern.
