Uh, er, I left out a critical word in the following paragraph in my
original message.
Sorry,

Question #2: If a boat had a lot of addtional flotation, particularly
low in the boat as in the bilges and under the cockpit floor (places
where Bernie is proposing to add it), could that make the boat MORE
prone to turtling and more difficult to right once inverted. It seems to
me that if the boat was on it's side and WATER was entering the cabin,
flotation in the bottom of the boat would actually _encourage_ the boat
to continue over into the inverted position whereupon the flotation
would make it very stable upside down.

David:
Not more prone to go upside down. But, a lot harder to remain upright once
full of water. Somewhere, (who remembers where once a couple of weeks have
passed?) I read a treatise where discussion concluded that flotation should
be placed under gunwales (side decks) and not near bottom to encourage vessel
to recover. Like a ball with weight on bottom returns upright. Well maybe a
poor comparison but general idea...
So flotation placed high encourages upright flotation...

Solar Fry is right on ,low flotation will tend to keep
the boat keel up, once it is up. I think if you want
extra flotation stuff a truck inner tube under one of
your cockpit seats and inflate it.(not too tight) in
other words, high and to one side. This should make
the boat want to roll over ,keel down. Right? I`ve never
tried this but, it sounds good. If it don`t work I will
allways think it should have....
