Your ship is in shallow water and the bow rides up on its bow wave while the stern sinks into a depression of its transverse wave system. What is this called?
Official USCG Answer & Rule Citation
Correct Answer: Option C — Squatting
Squatting is a hydrodynamic phenomenon occurring in shallow water where the vessel's pressure field interacts with the seabed. This causes a change in trim and a decrease in under-keel clearance, as the bow wave and stern depression effectively pull the vessel deeper into the water column.
