>>This resulted in a small metacentric height, roughly speaking the distance between the centre of mass and the centre of bouyancy.
A common misperception. The initial GM is the distance between the vertical center of gravity KG, the metacenter KM. The metacenter is given by:
KM = KB + BM
KM is the distance from the Keel to the Meteacenter
BM is the distance from the Center of bouyancy and the Metacenter and is given by:
BM=I/V
I is the moment inertia of the waterplane and V is the volume of displacement.
I is why beamy ships are more stable than skinny ones.
