I am looking at an older wood drift boat (approximately50 years old). It is in good but not "show" condition. I would use it on fairly mild water. My primary issue is storage. I do not have an inside garage to store it in. How will it do outside if I make a cover for it and also a shelter to keep it out of rain/snow and sun? I am in southwest Idaho where it is dry, but cold in the winter.
I am in the same situation as you. I don't have a place to store my boats.
I have found that if you roll the boat over, moisture collects under the boat and causes wood to swell. Now I tip the boat up and cover it with tarps. I string a line from stem to stern and prop it up with some posts under the rope in a few places to make a tent. They get covered up with snow which needs to be removed now and then. Don't just walk away till spring. Check it from time to time to make sure things are in place so standing water and ice does not build up. If possible find a barn or shed you can rent. If it's out of the rain and snow it will do better.
I have a couple of senior woodies, one about 16 years old, the other about 24. I am lucky enough to now have an open air shed to keep moisture out during the winter. The key to me for finish quality and wood quality is protection from the sun. Before I had a boat shed, I did as Ihedrick just posted. Then the key was, as he said, keep checking - just like cooking.
If you can get a hold of some 2x4's then you could build an A frame then cover with tarp.The snow will keep sliding off/down so probably less maintenance.
