(OP)
Can anyone help with a calc for overturning or stability of a floating vessel (like a pontoon or barge)?
Thanks

RE: pontoon overturning/stability
Sure, what are the particulars?
lenght, beam, draft, displacement, Center of gravity, second moment of the water plane area (transverse), center of buoyancy. This information will give initial stability. Stability at extreem angles(>10 deg) is different.
GM = KM - KB = KB + BM - KG
GM positive is stable, where KG is distance from keel to center of gravity, KB keel to center of buoyancy, and BM is
BM = It / Displacement
from this you can figure out your righting moment
M = GZ * displacement
where GZ = GM sin(tha)
cheers....
