Hydrostatics and stability

Principal parameters to describe a ship


The main dimensions of a ship are: LBP = Length between perpendiculars LOA = Length overall LWL = Length at water line B = Breadth D = Height T = Draught (some use "d") F = Free board Some other used characteristics to describe a ship are: v = speed DWT = dead weight Δ = total mass of the ship with cargo

Buoyancy


The total weight of the ship: $$W=M*g$$

The absolute value of the water pressure: $$p=rho*g*(T-z)$$

Fz = Archimedes force
