ahead of time if this is a well beaten dead horse.
i am finishing up one of Platt Monfort's boats - a pure one with no
plywood - and am wondering about the advisability of reinforcing the
covering with hypalon or whatever - or even useing heavier heat shrink
nylon. I live in the Pacific Northwest and will be useing the boat in
lakes and the ocean. It will probably spend a fair amount of time on top
of my rig - so will have some UV exposure. but will be stored away from
UV.

Platt suggests 2 possibilities. "Monokote" film available from Tower
Hobbies and "Plastikote", a liquid rubbery substance available from
hardware stores. Both are mentioned on his web site, gaboats.com.

If you want a tough coating, seal the fabric with a couple of coats of ZAR
satin polyurethane, then coat it with Gaco UA-7000 aliphatic urethane. This is
the method that Bill Low of Willow Kayaks uses and I can attest that his boats
are incredibly durable.
