I contacted Wenonah and they were great, told me that it is most likely Tuff-weave. We talked boats for awhile. While he couldn't give me the exact boat details as it was too old, we went over it well enough. I'm starting to think about a lighter boat, as this particular canoe was only 51 pounds, but it still felt heavy. The main obstacle is that the consignment store won't allow for a test run. Without being able to lift it on the car, and see how it performs in the water I'm a bit leery about buying it. So I'll look around a bit more. We've decided to keep our Old Town Discovery 169 and use it for more challenging runs when we have extra couples to help load and unload. Once we're on the river we're fine. Thank you for all the suggestions.
