flotation Foam
Ok, I'm in the middle of a rebuild/repair on an aluminum boat. I just
jerked the plywood sole out of it in order to replace it with aluminum decking, and I found what looks like plant arranging foam between the ribs for flotation. It soure doesn't look or feel like a sealed cell foam. Its also quite a bit narrower than the space available. I was thinking about replacing it with foam that fits snug between the ribs to increase the flotation slightly, but I'ld like to use the best thing possible. Would styrofoam be more suitable? I know styro hardly absorbs any water at all. It lasts indefinitely as the flotation under docks as long as its not exposed to sunlight. . How about a poured foam? Are there any that form sealed cells as it hardens? Would it work here, or would it be too hard to get it level with the ribs so I can put in the new sole? I'm not sure I want poured foam in here anyway, as any water that comes in the forward deck hatches etc drain through the strength creases in the hull to the back of the boat where it can get kicked out by the bilge pump. I'm thinking if I can styro that its just the right thickness it will be the best foam replacement, but there is a lot more experience in this group than I have. Bob La Londe www.YumaBassMan.com |
