You've got a little gem there! It's not a coleman, looks to be made out of fiberglass. What are the specs on it? Length, width at center? How much do you think it weighs?
Depending on length, you might only need to put your carrying thwart in it, looks like the seats are rigid enough to act as supports.
Now to the nitty gritty....that canoe is going to paddle like a pig, but if you decide to upgrade, never, ever sell it. Square sterns are like gold, especially if you hunt and fish. I had a nineteen foot square stern, paddled it for a year, managed all right, but then got a little 1.5 horsepower and went everywhere in that thing. Really regret selling it.
Looks to be in pretty good shape, have fun!
