There is one major flaw in your calculation.  The center of buoyancy is not included.  Many ships have the center of gravity above the above Archimedes center of force.

    Nomenclature difference:  "center of buoyancy = "center of displacement"

    Fred,

     

    You took one of the more unique conditions for ship stability.  Your calculation is typically done for submarines,  but is possible for surface vessels. (By the way, the center of buoyancy for a submarine does not change.)   I come back to my original comment, the center of gravity for a surface ship is normally above the center of buoyancy.  Reference "Principles of Naval Architecture" pub by The Society of Naval Architecture and Marine Engineering.
