A _rough_ rule of thumb is that if you use full thickness of ply as
designed, and only want this to stop checking and help keep the wood
dry, then use a really light cloth, but reinforce all corners, as
that's where most abrasion is. Also two layers on the bottom. If you
use thinner ply, then build up with cloth until the boat weighs the
same as it would have in ply (reasonably well-laid glass cloth will
take up its own weight in resin, roughly), and you will probably have
a stronger boat.

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.

Otherwise, talk to the canoe's designer. Always a good idea.

Will do.

One last question, I know I need to tape the inside and outside with
fiberglass tape on the seams, but If I cover the whole outside with
cloth, do I still need the tape on the outside of the seams?

Unless you can cover the whole boat with cloth before you move it from
the building jig, then yes. It's literally what holds the whole boat
together.

I don't have a building jig on this design. It is a simple canoe with
only two "corners"--One chine in the middle of the side, and then a
chine where it hits the bottom. Not sure if that would be considered
one chine or two, but either way it is a simple design.
