floatation

[ken baker]

Any one have a good source for LARGE blocks of styrofoam used for packing voids as floatation devices??? Grand son is restoring a '60s Fireball and it is all gone...long gone. Plus the styrofoam in my O'Day 22 is pretty ratty so it should probably be replaced also.

2# pour in place foam is good, and can be

had pretty cheap. If you don’t want it to stick to the boat, line the area in wax paper. Allow the stuff to start foaming before you start pouring if you want to do the wax paper thing. This stuff will pretty much last forever.

Allow room for expansion

Ken - Don954 is right, it's good stuff & not too expensive. But make sure you leave enough room to allow for the foam to expand 'cause it can develop an enormous ammount of force as it cures. Products differ, so read the directions.Twice !

There's foam and there's foam...

Just make sure before you 'foam on" that you're using closed cell stuff. Open cell foam absorbs water eventually, as the 1500 pounds of extra weight in my father's 18' center console boat will attest. Be wary of standard Home Depot stuff. Sometimes cheaping out is no economy.

Boat foam

This is all good info. Don't let it scare you off, cause poured in place is the only way to go, but take care. You don't have to do it all at once. Figure up to 10 times expansion, but put in 1" with space all around and let it finish expanding, then put in some more. Don't try to completely fill any void. Finish up with chunks of the same stuff.
