    >>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:


    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.
