    The points are derived from constructed boats

    The weight pro square meters is as follows:

    Hull > 1m x 1m x 2760kg*m^3 x 10mm = 2760 kg*m^2
    Keel > 1m x 1m x 2760kg*m^3 x 20mm = 5520 kg*m^2
    Sup > 1m x 1m x 2760kg*m^3 x 7mm = 1932 kg*m^2

    This means that the estimated weights are besed on the following thickness for a gamma aluminum = 2760 kg*m^3

    Hull > 10 mm
    Keel > 20 mm
    Sup > 7 mm

    OK?

    Guillermo is right...

    Hull > 27.6 kg*m^2
    Keel > 55.2 kg*m^2
    Sup > 19.32 kg*m^2
