Yes, Harvey Golden has an excellent website on arctic skin kayaks and umiacs. Perhaps you will find the information you are looking for there. If you are a seasoned woodworker you would mostly need a plan. But there are ways to tie knots that are authentic, etc. There is a resource page for how to books, and materials. I wondered what I would use myself. he uses cotton canvas which has an adress for where you can get it. And paint. He is doing an extensive search for all of the sea kayaks left in the world and documenting them. And making plans for all of them. I hope this helps you. Just go to google and type in harvey golden.
