: I am not a design engineer, and I like tinkering with alternatives, but I
: think you miss the point of using plywood, which is to make the craft
: lighter and gain the advantage of better fatigue resistance and also you
: get to enjoy the timeless beauty of the wood. I believe kayak plywood is
: lighter than an equivalent panel of fiberglas.

: To preform fiberglas panels, then stitch and tape them together might just be
: a cruder, less effective way of making a fiberglas boat than using a mold.
: With the mold you can lay the whole thing up in one shot and then let it
: cure, so it would be stronger, (i.e. STRONGER THAN S&G FIBERGLAS NOT STRONGER THAN WOOD S&G- JR) but ("STILL" - JR) heavier than a wood boat.

: Also, bending fiberglas panels somehow seems like a bad thing, after they
: cure. The advantage of fiberglas is you can mold in any shape while wet.

: Also, polyester is never as good as epoxy, except for the lower toxicity of
: hte fumes and the cost - its heavier, weaker and shrinks while curing.

: Maybe try exploring how to use wood and dispense with the weight of
: epoxy/fiberglass but somehow otherwise obtain the extra strength and
: protection of fiberglas skin, if you succeed you could revolutionize this
: niche.
