Talked to a friend who makes boats .... He told me about this ... May be some possibilities .... This is just FYI , and not an official endorsement .... yet ...
His words “ yesterday I spoke with the guy who owns the DuraSip laminate company out of union, ms. and told him of my idea of forming the canoes from six strategically shaped panels of his material, sewn together and glassed at the seams, interior ribs/ seats to be done in closed cell foam under glass...sheets are available any length you want, up to 8ft wide, in .040 or .050'' thickness, phenolic sandwich of chopped strand with a light woven roving in the middle. “
I’m sending off for samples , as this may apply to a foamie ( or others_) ... May be that hard finish everyone is looking for instead of canvas texture... We’re investgating ..
