I'm planning to build a baidarka using Brinck's book, except that I want to use an all ash frame and heat-shrink nylon or dacron cloth. I'd really appreciate help with a few questions:

1. Is 8 oz cloth strong enough? 12oz?

2. If I make the gunwales 3/4 by 11/2, the hull ribs and stringers 1/2 by 1/4 and the deck ribs 11/2 inch thick, will the frame be strong enough?

3. Are there fundamental differences in workability or performance between nylon and dacron that I should consider in selecting which to use as skin?

4. What paint would work best for smoothness and durability, Hypalon or polyurethane?

By strong enough, I mean for my use as a recreational paddler (180 lbs), mostly day trips with the occasional overnight, no rock surfing, some paddling on the ocean side of Newport/Block Island Sound. I'm located on Narragansett Bay.

Thanks to all.
