Hi muddin,

Canoes, almost by definition, have pure displacement hull shapes intended for extremely efficient low speed operation. They serve this function very well.

Most attempts to power or tow canoes to higher speeds tend to result in the canoe either becoming uncontrollable, or breaking up. (Notably, they cannot be towed behind powerboats at planing speeds; quite a few have been destroyed this way). Powering a canoe with a bigger engine than is necessary to get it to a bit past hull speed is not a good idea, and could very well result in the loss of the boat.

Canoes can be flat bottomed and plane, shallow arched bottom for best secondary stability (these are best for rougher water), or round for best speed under paddle. The transome stern doesn't enter into it unless the boat is loaded stern-heavy or designed to be a boat other than a canoe unless the stern draws down and brings the transome into play.
Canoes have a "canoe stern", at least under the water, and any that I know wouldn't plane well. I presume you want to get somewhere fast, then paddle around. It is a pleasure to glide well and anything that planes well will not glide well. This is practical experience, as I know it. Perhaps a designer can enlighten us more.

muddin,
I just re-read your dimensions: 3'6" beam on a 12' LOA vessel is awfully wide for a canoe. Are you sure that's what you have, and that you aren't talking about a small skiff of some kind?

this is my canoe

Fisher 12' (Square Stern)



Perfect for sporting activities and recreational use, the Fisher is incredibly stable and can be rowed(2 position) or propelled by a small motor (up to 2 hp)! Fabricated in fibreglass, with heavy duty aluminum gunwales and hardware, along with wood slat seats. In addition, each with sports external sponsons to provide "stand-up" stability. Yet our Fisher is still small enough to tie down on any car or in the back of a pick-up. A very versatile little boat; small but mighty!

Length 12' Beam 42"
Depth 14" Weight 65 lbs.
Capacity 420 lbs.

Buy an exercise bike of row boat and get fit whilst loosing some of those excesses, then you can better enjoy the rest of your life and be around longer to do it You need to loose about a third of your weight at least...

The non-boat info, consider a bonus, and just as important...
