I have a 1931 Old Town OTCA 17 that I got from a friend about 15 years ago. He simply asked that I take it away along with the utility trailer I was buying from him. I re-canvassed it once but need to do it again. As an architect/designer I like to explore alternate methods of construction on almost everything. The stems were re-cut using marine grade plywood and have held up quite well. I’m thinking now of using a poly coated nylon duck rather than canvas so I can save a lot of weight. I know this will stand as heresy to many members, but I just need to ask. The material seems to have enough stretch to pull tight around the hull. In cut or tear tests, it held up to the same abuse as a piece of canvas when hit with a knife. The resulting clean cut can be patched with a variety of patch kits made for dry bags, jackets, inflatable boatsm etc. What am I not thinking of in this scenario, oither than losing the 'traditional' aspect? I'm looking to make a serviceable craft, ready for most lakes, swamps or mild river runs.
