: John - I think I would disagree with you regarding the propensity of
: "composite" foam to dent.

Hi Dick,

I have not tried to laminate glass onto foam but I will give you my reasons for thinking fiberglass would delaminate from foam after sustaining a bump from rocks, etc. About a year ago we had a long decussion about this subject and there were several links offered up for looking into this and I check out all of them. One link was a surfboard builder that used a foam core that was tough but quite expensive. He laminated over the foam core with (graphite-Kevlar) sp. , can’t think of the name I want but you know what I mean. After extensive use of his surfboard the laminated surface had become so delamated that it flopped loosely from the foam. That’s when I decided to stop thinking about building a foam boat out of pink or blue foam which is much softer the foam he was using. When I got home from my kayak trip last year and got to looking at my scratches I saw some dings on my boat and realized that if it had been foam I would probably had a delamination there because the foam is so soft that the glass would easily pull away from it. Now if you put so much glass on your boat to stiffen it up then you defeat the purpose of having a light boat by using foam in the first place. When it warms up here in IN I will epoxy some glass on blue foam and test it. I would like to know for sure, myself.

Take care,
John
