Just a suggestion: They sell big rolls of Tyvek at most lumber yards. If your at all handy with a sewing machine, make yourself a fitted canoe cover. Seems that might be some protection for a canoe? The thing is, I don't know all these new materials and just what their interaction on each other is or might be, come the time to paddle you might find that the Tyvek has glued itself to the canoe! Or maybe the canoe to the Tyvek?
Where I live we get winter storms with wind that just about knock you over. In my limited experience it's best not to underestimate what the wind is capable of.
I once had a chance to explore a German (WW2) concrete artillery bunker; on some stormy nights I wouldn't mind having a house built like that!
