After looking into the different types of foam, its now got me thinking about replacing the floor under the front seats with a sheet of Polyurethane Foam sheet instead of wood. Then covered in fibreglass at the same time as the rest of the floor.
Can anybody see why this wouldn't work or has anybody tried it already ? sheets |

Oh, 10-4 on west marine, the prices are ridiculous, like double. But there is one in my town. And the staff there are real boaters, I just ask questions. Not many purschases
Thanks much for Jamestown marine link What are your thoughts on TAP plastics x30, in my town aswell |

Thanks for that..... Read this on the Isothane web-site : LD40 is our general purpose foam system that has a wide variety of moulding applications where a foam with a gradual rise is needed. The product is a two component system, CFC and HCFC free and produces a rigid foam with an approximate density of 40kg/m³. The foam has good compressive strength, cell structure and other physical properties. Now my maths aint brilliant, but with the power of google i "think" 40kg/m³ = 2.5 lb/ft3 So i'm guessing were good to go

Don't knock West Marine. If your an educated shopper they can be helpful. Down south I can walk to one and they are open late. When I replaced my exhaust hoses they were the same price as I could find on line and I had them in just a few days. I think they now price match as well.

If you are using the foam for floatation the key specs are 2lb density (that's per cu. ft.) and closed cell for low moisture absorption.
Pour foam at Jamestown
Daryn, Why do you keep going to that blood sucking "marine supply"???

I’m interested in finding the answer to foam question too. I know it needs to be closed cell marine grade Some big box can foam is not. So I was looking at TAP plastics X30. And there’s always west marine brand $$.

I know the foam v no foam debate has gone on for years lol I've decided to go with foam again, but not sure on specs of foam. Would the foam in the link below be ok to use on a 1980 Ski Nautique ? Foam I can buy locally |
