Yes, those are important factors, and they are not addressed at all in my
calculations.

Kamens's premise is that accounting for just the ballast, given a
wooden-core fiberglass hull, gets you in the ballpark.  If he's right, we
still need to add a lot of buoyancy to a SJ23 to keep it afloat when
flooded.  If he's being too liberal, we need to add an _awful_lot_ more
buoyancy.  Many of us (author included) seem to have added heavy
equipment--spare batteries, extra anchors, outboards.  That certainly won't
help the buoyancy.

Back to Bobby Kawamura's original question:  I think we should conclude
that the boats will sink when filled with water, and take whatever
precautions are appropriate to the waters we're sailing on.
