The wood I am using is 1/8th Okume

If you're using plywood that thin, do yourself a favor and glass it on
both sides. Unless you screw up by making huge fillets and endpours,
your boat is going to be featherweight anyway (probably under 30#), so
what difference is an extra couple of pounds for full inner glass going
to make? Unless this is strictly an experiment to push the limits of
light weight, what's the point? Do you want a boat that you can actually
paddle regularly without worrying about damaging it?

There's a concept in cycling commonly called "stupidlight", the
lightening of components to the point that you sacrifice functionality
and durability. It applies to kayaks too. Light weight is not the be-all
and end-all and there are limits to how light a plywood boat can be. If
you really want something ridiculously light, build one of Platt
Monforts "Geodesic Airolite" boats. http://gaboats.com/
