What may occur in shallow water when resistance on the bow increases, raising it and lowering the stern?

In shallow water, when a vessel experiences increased resistance on the bow, this can cause several hydrodynamic effects. The correct answer, squat, refers to a phenomenon where the vessel's bow rises and the stern lowers due to the interaction of the hull with the shallow water. As the bow rises, the water flow around the hull changes, resulting in a reduction of water displaced, which can cause the stern to sink lower in the water.

This situation typically occurs when the bow encounters increased pressure and resistance from the shallower bottom, leading to a reduction in forward motion. The result is that the stern may squat deeper into the water due to the overall change in trim of the vessel, impacting its maneuverability and stability. Understanding squat is crucial for safe navigation in shallow waters, as it can affect the overall performance of the vessel and lead to grounding if not managed properly.

The other options, while also related to vessel stability and orientation, do not specifically describe the effect seen when the bow is raised and the stern is lowered in the context of shallow water conditions. List refers to a side-to-side tilt, roll involves rotation around the beam axis, and pitch concerns the rocking motion around the lateral axis. None of these directly address the resistance and resulting trim
