Bought a used canoe and noticed it tipped easier to one side than the other. After looking closer at it, I now realize one side of the canoe is steeper than the other. Can this be fixed? It's my first canoe, so I guess I didn't know what to look for when I bought it. The owner told me it was stored in his garage and it's only 7 years old. My guess is perhaps he stored it propped up on its side? I really hope I can fix this somewhat. It's not unusable, but it very obviously tips one way.
