Well, congratulations on returning it. With this one I did look it up on the Old Town site. First off you ought not need to repair something new, that's just silly. Second, in my opinion, the thing is a pig: 14' 6" and it weighs 79 pounds??? That center entertainment console looks to be bolted in and I can't imagine how you could roll it up on your shoulders to carry it.
Fireman, you really need to look at real canoes. They are light nimble craft that let you explore and paddle where more clunky water craft are excluded by their brute awkwardness and impossible-to-carry mass.
Look at the photos in the trip reports here; those are canoes. As far as molded seats go, most of us find they are not necessary and some fraction kneel with just the butt resting on a cross thwart, makes for a more stable canoe. Notice when you look at the pictures just about all have a center carrying yoke of some sort. Although carrying our canoes may not be our most favorite thing to do it does allow us to reach otherwise inaccessible places and there is a winnowing out process that results in a better quality of people you meet the further in you go.
There are some deceptively simple seeming tools that evolved during mankind's long history. The ones that come to my mind are the potters wheel, the longbow, and the canoe. When you look at one of them, at first you might think "Shoot, there's nothing to that" . But it's not true. Each requires considerable practice to acquire proficiency. I'm not saying you won't have fun learning but you will need to practice. Our canoes really aren't much in terms of complexity but they will allow a freedom that extends way beyond what their simple seeming looks would promise.
These tubs you've been looking at are painful to contemplate once you've been in a real canoe.
Best Wishes, Rob
