There are some foams that, when burned, put out fumes that are deadly. Why not just use jugs that have screw caps and get the bouyancy using air? -----Original Message----- From: montgomery_boats-bounces+n9ca=comcast.net@mailman.xmission.com [mailto:montgomery_boats-bounces+n9ca=comcast.net@mailman.xmission.com] On Behalf Of Tom Hauser Sent: Wednesday, May 30, 2007 3:07 PM To: 'For and about Montgomery Sailboats' Subject: RE: M_Boats: mystery smell Bill: When I bought Kestrel (M-15 #175) last year, there was no foam forward but two very large blocks underdeck aft. I washed both with soap and light bleach. I will try to replace the forward flotation (although I don't know if the original boat had styrofoam). I plan to use gallon milk jugs filled with spray foam insulation. This is the spray can you find in Home Depot, etc, to fill in around light fixtures, door seams, etc. It doubles or triples its size as it is sprayed and dries. It is very light so it should provide bouyancy. I will fill one jug and see how it floats. It it works, the foam will be sealed from dirt and mould by replacing the milk jug cap. The containers will be easy to install and remove from under the V-berths (in theory). Finding large chunks of foam is not easy. It chips and breaks easily and then is a mess to clean up if there is static electricity around (caused by empty Coors Lite cans, I think.) Any other ideas?
