Each of the features you’ve cited will, certainly, have their proponents - but will also have their detractors. It seems to me, you might be looking at four questions:
What are the pro’s and con’s of ...
1. Double-Ended (canoe stern) Hulls ?
2. Cutter Rig ?
3. Ketch Rig ?
4. The combination of Cutter-Ketch on a Canoe body ?

Personally, I’m not particularly fond of any of these layouts. I have neither the time, nor expertise to offer a detailed analysis of the questions - but will start the ball rolling with a couple of basic observations:

Each of these will add cost to a comparable Bermuda-Rigged Sloop, with a modern underbody.

1. CANOE BODY - DOUBLE-ENDERS:
- more difficult to utilize the stern & lazarette for such things as boarding ladders, wind-vanes, and etc.
- wave-splitting ability countered by reduced reserve buoyancy, and volume (storage).

2. CUTTER RIG:
- more flexible sail combinations offset by more complicated sail-handling and larger sail inventory requirement.

3. KETCH RIG:
- as with Cutter, more flexible but also more complicated.

I look forward to some excellent detailed replies (we have some true “experts” aboard), and a spirited debate.
