Q. 1) What do you mean by squat ?
X
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

X
total mass of cargo,fuel,f/w,etc that a ship can carry at the time she is floating in SW with her summer loadline at the water surface.
When a ship is delivered from the yard (with machinery, appurtenances, fixtures) its weight without stores, fuel, crew, etc is called "Light ship". Anything weight which is not a part of Light Ship is called deadweight. Eg Crew, fuel, stores, ballast, cargo, lubes etc.
Deadweight tonnage (often
abbreviated as DWT for
deadweight tonnes) is the
displacement at any loaded
condition minus the lightship
weight. It includes the crew,
passengers, cargo, fuel, water,
and stores. Like Displacement, it
is often expressed in long tons or
in metric tons.
