is the mass which must be loaded or discharged to change the ship's mean draft in salt water by 1cm

the vertical through the centre of buoyancy at two consecutive angle of heel intersect at a point

The ship is said to be heeled when, when she is inclined by an external forces

A ship is said to be listed when she is inclined by internal forces within the ship

the vertical through the center of buoyancy may be considered to cut the center line at a fixed point

Is the vertical distance between G and M

if G is below M

If G is above M

A ship is said to be in stable equilibrium, if when inclined, she tends to return to the initial position

Is the perpendicular distance between the center of gravity and the vertical through the center of buoyancy

When G coincides with M

sink

rise

change shape of underwater volume

metacentric height

metacentric radius

height of metacenter

vertical COG

the point at which all the mass of the body may be assumed to be concentrated

Is inclined to a small angle tends to heel over still further

she will tend to return more quickly to the initial position

easier to incline and will not tend to return so quickly to the initial position.
