A guy down the road has a Old Town Royalex canoe he stored under his deck for about 12 years. He made brackets to store it upside down well off the ground. He did not use it much pretty much just laid there. He offered to sell it to me. Overall it is in very good condition - some scraps from the river but no real damage. Looks like a couple drops of deck sealer in a couple places from when he sealed his deck on the bottom.
I would think that keeping it under a deck (garage would be better) would be okay since it keeps most of the sun off the canoe bottom but still lets there be air flow to keep it cool and dry it. Don't know if the deck sealer spots could be removed seems like they are stuck pretty good. Any thoughts on this canoe based on being stored under a deck?
FYI - I have other options for a canoe but this is a nice canoe located close to home - guy seems honest.
