Ok I played with a sketch over lunch.
This is currently 32" x 14'. Will carry 350 pounds with no trouble at all. Could take up to the 600 pound range. But 400 is the most that really should go on board.
Not the prettiest looking thing. Bow and stern ends are kept low to minmize the effects of wind. You'll need some sort of deck the first 3' or so on the bow with a small splash rail to keep water out of the inside for choppy water.
Bow entry is pretty verticle but that will help with speed a little bit. Could be swept back some for a sharper entry.
It's a square stern so it won't have blazing speed. But with the tumblehome sides, and most of the width near the water, sitting in a high position or even standing on the floor of the canoe and poling should not a be problem.
The slight V bottom should help with tracking. I have not done it much, but I know poling and keeping the boat staight is not always an easy task.
A trolling motor would scoot this along pretty darn fast. 3hp OB is the max you could put on it.
