Foam???

[Boat Craze]

I just purchased a boat and the inside was gutted out. I am installing new stringers but and marine grade plywood. But do I use in between them?

Huh?:confused:

If you mean for flotation to fill up the cavities in between the stringers, deck, and hull, yes foam will work. Two part closed cell foam is what you want. Probably 8lb density.

Can I get it from home depot or lowes?

[basstardo]

That I don't know. There are several online retailers that have it in no particular order...

http://www.fgci.com
http://www.jamestowndistributors.com
http://www.raka.com - They may not carry it actually.

If you do a search on google for two part closed cell foam you should be able to find it.

I have a 16' Infinity how many stringers should I have?

[jimslade]

two with side floor supports every 6 ft

What do I use for side floor supports? What type of wood do I use for the stringers?

[nero]

www.uscomposites.com for cheap two part foam. several different densities available. Best prices that I have found.

Does n e 1 know what type of wood do I use for stringers and supports?

[jimslade]

My personal preference is pressure treated ply(well dried out) 2 layers of 3/4-total 1 1/2 for the stringers 1/4 inch for the sides. Make sure that the stringers DO NOT touch the bottom of the boat. You can set them just above the bottom with a thin layer of foam.

ok thank you so much for the helpful advice

can you use just spray or regular foam from wal mart under the stringers?

It might be worth your while finding a local with the knowledge to get you started with your project ? Nothing difficult in glassing in new stringers, but you don't want to get it wrong.
