HCR,
Everyone's needs vary so I will not make any suggestions, but, here is a good web site that may help you in your search. I purchased a MichiCraft alum. canoe in 13' from them many years ago and was satisfied with their service. They have a square stern 12' canoe that you may or may not be interested in. It is just a good site to explore what is out there.

Good luck with whatever you purchase

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
