The squat effect is the hydrodynamic phenomenon by which a vessel moving quickly through shallow water creates an area of lowered pressure that causes the ship to be closer to the seabed than would otherwise be expected. This phenomenon is caused when water that should normally flow under the hull encounters resistance due to the close proximity of the hull to the seabed. This causes the water to move faster, creating a low-pressure area with lowered water level surface

The procedure which we use to test launch lifeboats is:
• remove gripes/lashing wires
• no one boards the boat
• launch boat to water, doing brake tests on the way down
• crew go down embarkation ladder or accommodation ladder and board boat
• boat is taken away and engine/steering etc checked
• boat returned and hooked on
• boat lifted about 2 metres above water
• self-release wire tested from inside the boat and boat landed back in water
• if necessary, boat lifted again about one metre above water and quick release mechanism tested
• all crew disembark and climb up ladder
• boat retrieved with no one inside
• boat secured
yes we can,but it is possible only if the vessel to be overtaken permits.through a appropriate sound signal
