What effect does bank cushion have on the hull of a vessel in shallow water?

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

The correct answer is D) the hull has a greater pressure on the land side of the bow. When a vessel operates in shallow water with a bank cushion, the narrowing of the waterway creates a greater pressure on the bow of the vessel compared to the stern. This is because the bank cushion effect causes the water to build up and compress on the bow side, resulting in increased pressure exerted on the hull in that area. The other options are incorrect because A) and C) describe a lesser pressure on the hull, which is the opposite of what occurs due to the bank cushion effect. Option B) refers to the stern, but the increased pressure is actually on the bow side of the vessel in shallow water with a bank cushion.
