Restoring a boat

[bdover]

My dad and I are restoring my grandfathers 1966 starcraft 18.5 ft aluminum boat. We got the whole interior stripped out of and already replaced the Transom. Between the floor and the Hull there were giant pieces of Styrofoam blocks. I assume this is for sound deadening. Over the years the mice tore it up so it'll all have to be replaced. Rather than trying to find Styrofoam blocks then cutting them all to fit I was considering blown in insulation, until I realized its not waterproof. Does anyone have other suggestions.

The foam is for floatation if the boat flounders. Replace it with blue or pink foam insulation.

+1 you can find the pink or blue at home depot or lowes - just make sure it is closed cell foam which the pink or blue is.

foampower.com is not a flotation foam - you need closed cell (open sell actually absorbs water. You can get 2 part expanding foams for those tight places

As others have mentioned, go to HDepot or Lowes, and buy the pink or blue insulation. Easy to cut with a sharp kitchen knife or razor knife, won't hold water, and may save your life in an emergency.

The pour in foams get expensive fast. Use the sheet goods, and a can of fill-foam to secure in place, if you really want that. I tend to think it's better leaving it a little loose in there, to prevent moisture build up under your flooring. A 1/2" gap should work fine to let any moisture get out.
