I did a few trips with Mike Hurley, who used to write the "Hurleys Journal". He had a wood canvas Cheemaun, built by someone down near his home in NC. It was a nice canoe and I'm no expert on making a wide canoe go fast, but it was wider than I thought necessary and seemed pretty slow.
But my Bob's is wide and after I learned that when you lean it over a bit it goes a little faster, so maybe the Cheemaun is the same.
For a 15ft canoe, imho, the Chestnut Chum or similar 15' x 29-30" wide w/c canoe is hard to beat for solo tripping or a day trip with grandkids.
Carrying Place Canoe and Boat Works
http://www.carryingplacecanoeworks.on.ca/html/canvas.html has a good selection of 15' wood canvas or strippers. I bought a set of Jacks Special plans which are taken from a Chum. I called the owner and he was very helpful on the phone and answered all my questions
Here he is in a Jacks Special photo I took off his site:
Here's one showing how some folks use them for freestyle taken off the Carrying Place site:
And I have posted this picture here and other places, but thought it would help to show the differences width vs length makes on my canoes
Left is a green Chestnut Bobs Special, 15' x 33" (36" at the waterline)
Middle is a red Chestnut Chum, 15' x 29 1/2" plank to plank at the gunnel, a little wider at the waterline
right is a green Chestnut Pal, 16' x 32-33 (it's too high up on a rack right now to measure correctly, but it stays about the same at the waterline-33 maybe)
