So, probably tape chines, inside and out, cover entire boat again
with like a 4 ounce glass and then throw a second layer of 6oz, or a
synthetic, on the bottom, and maybe wrap it a couple of inches up the
sides.

The second layer at 6 0z may be only 4? Watch the weight. You have to
carry this thing. Looking at the canoe as a 2' 6" half tube 5 yards
long, 10 oz of glass + resin = 28 lbs!


Does the strength come from layers or weight? i.e.: would one layer
of 12 oz be as good, better, or worse than two layers at 6 oz? or
three layers of 4 oz, 6 layers of 2oz 24 layers of 1/2 oz....etc....
I know in plywood, the more layers withina givin thickness, the
stronger the plywood. is it the same in fiber/epoxy?

More layers of thinner cloth will be stronger and more flexible than a
single layer of heavier cloth.
