I can see where the tumblehome makes for a little chore removing from the form, but yours is a really nice shape! My remarks weren't criticism, just curiosity. On my build I found the planking layout to be difficult. I had only a few pieces of planking about 9' long, the rest shorter and many had tiny knotholes. These had to be carefully positioned so that the holes fell on ribs. I'm itching to make planking from some clear Alaskan Yellow Cedar I found. It is a bit heavier than Northern White Cedar, but perhaps stronger so maybe I can make it thinner, 5/32" or so, and end up with a reasonable weight solo canoe. The dimensions of yours seem about right, maybe a tiny bit narrower.
