In most cases, when a large merchant vessel enters shallow water at high speed the _______________.

A speed will increase
B vessel will rise slightly, on a level plane
C maneuverability will increase
D bow will squat farther than the stern
AI Explanation

The correct answer is D) the bow will squat farther than the stern. When a large merchant vessel enters shallow water at high speed, the phenomenon of "squat" occurs. Squat is the change in a vessel's trim and sinkage due to the interaction between the vessel's hull and the surrounding water. As the vessel enters shallow water, the water flow around the hull is constricted, causing the bow to sink more than the stern, resulting in a bow-down trim. This effect is more pronounced at higher speeds, as the water flow and pressure changes become more significant. The other answer choices do not accurately describe the physical effects of a vessel entering shallow water at high speed.
