Good Deal?

192"(16’)x36"(3’)x6" slabs of 4lb (high density?) EPS

I was think of getting 4-5 panels to glue up vertically and hot wire and vacuum bag me a bamboo skinned 4-man outrigger canoe out of the stuff?

4lb too heavy for 16’ panels?

Is this a waste of this type of foam?

each panel is cheaper than a 4’x8’x2" panel of dow blue XPS at lowes
