Shallow Water Effect on Ship - Cult of Sea
Shallow water effects on a ship w.r.t “Draft & Maneuverability.” • As the hull moves through shallow water, the area which it displaces is not so easily replaced by surrounding water, therefore, leading to a state of partial vacuum as the propeller and rudder are still working.
SQUAT & SHALLOW WATER EFFECTS - Marine Teacher
Any Rolling, Pitching, and Heaving motions will all be reduced as the ship moves from deep water to shallow water conditions. This is because of the cushioning effects produced by the narrow layer of water under the bottom shell of the vessel.
Shallow Water Effect - an overview | ScienceDirect Topics
Due to an increase of the hull damping force in shallow water, tactical diameters commonly become larger, which is a typical shallow water effect that is widely known (ITTC Manoeuvring Committee, 2008).

This paper conducts a review on shallow water effects (SWE) and bank effects (BE). It summarizes the varying opinions from both experienced mariners and hydrodynamicists about SWE on factors such as resistance, trim, steering,
Maintaining Safe Under Keel Clearance -Shallow Water …
The effect of shallow water on a ship is: More ship's power is absorbed by the water due to increased friction. Usually sinkage is greater forward than aft for ships of tanker speed and displacement in any depth.
