Matt,Don't know about your proposal, but if you want max strength with min resin, use unidirectional fiberglass instead of cloth. Uni will compact to less thickness, therefore less resin.
I have not looked for uni glass, so don't know if you can get the right thickness of ply to equal the typical 6oz cloth, but you will need multiple directions to get the same properties in all directions. The uni will be about 8% stronger for an equal weight of cloth because it is straight not woven over and under the other fiber bundles.
I doubt it will have as good abrasion resistance.Good luck.
Thanks Marc, I know unidirectional is stronger but I find it tricky to use on curved surfaces. And as mentioned abrasion resistance isn't quite as good. I want a clear coat on the deck and with unidirectional cloth there's always a cross-thread that would remain visible. On the inside I would prefer -45°/+45° unidirectionals for a kayak but haven't found any in the low weight ranges. I'll see how where I end up with the night heron and decide from there on.
By the way, weight is an important goal but not the only one. I want a beautiful kayak that people might want to buy ;-)
