.. if you
do use epoxy you have to also use fibreglass cloth. on big boats they
recommend three layers of cloth and resin to "encapsulate" the boat. I've
seen a single layer of cloth and epoxy resin on a kayak which didn't do
much good at all.

I should add that once you get three layers of glass and epoxy on a
plywood kayak you've got yourself a very heavy kayak. I'd just go with the
plywood. However if you're building to someone else's design and it says
use epoxy then you should use it. Make sure the finished weigth of the
kayak is clearly stated in the plans.
