Hi John
As to the 50/50 handle used for some sailing canoes. I have always been a bit confused by the term. I am an American canoe person but do not live in the US. I have lived abroad for most of my adult life yet am part of the think tank on a canoe form that emanates from the US, hmm guess this makes me an expat (caught in the middle) sailing canoe hybrid.
As to beam, burdensome enough to carry a huge amount of stores, room to sleep in, stable enough to stand up in, two masts, a small decked cruising yacht and shallow......my taste in sailing canoes is just about the description you give above except for the burdensome part and the canoe stern part. I approach the challenge of developing sailing canoes for cruising with the theory of shaving away everything extraneous in both design and what gear I bring. With this statement I mean I go for minimalist everything as any small boat cruiser should. Taking this minimalist approach means I prefer narrow canoes as opposed to bigger, heavier canoes. I like nimble but nimble does not mean so nimble as to be a drama queen taxing me at every turn trying to keep her upright. Nimble means a balance between nimble in performance yet stable enough to sleep in, stand up, etc measured against narrow enough to double paddle effectively etc. This is because I prefer to double or single paddle instead of rowing. So far so good, Sylph has out performed on every one of my expectations, mainly the feeling of stability I get from her. As to load carrying ability I can load her beyond reason and sometimes when going offshore I fill her with air bags and do a little deck loading, which has never been an issue. Below is another photo of her loaded for an open ocean passage to Pakin Atoll. Yes running lights just for getting out of the harbor here in Pohnpei. I am the only sailing craft around and a tiny one at that so I have to be very careful not to be run over by local power skiffs (around dusk or dawn), which never seem to keep watch. Once at sea I remove them. Out here in the western Pacific there is simply no ship or boat traffic just wide open wilderness, sobering once at sea in such a small boat but always feeling secure because of the stability factor and the knowledge I can self rescue because I have set her up and tested all manners of self rescue. I end up sailing a diminutive pocket yacht in the form of a sailing canoe.
Here is a sleep aboard shot and a stand up and sail shot. I often stand and sail to stretch legs, see where I am going in a tight spot such as channels or entering a big boat marina filled with towers of (ridiculously large) power boats. When I need to see ahead I simply unhook one of the tillers from its self steering set up and stand up, there is never much drama about this given my 33" beam.

The sliding decks I have designed and constructed allow for a very roomy sleep aboard when pushed forward and aft. I also sit on the aft deck at times with feet in the cockpit when sailing downwind. I do this again for comfort, to read a book, have lunch, repair something etc.
Given that my canoe Sylph comes in at a whopping 52 pounds empty and about 70 with rig, flotation, etc I think she meets my minimalist approach quite well. Now that I am finishing off my new canoe (a Bufflehead hull) I aim for even better performance sailing, sleeping aboard. Like Sylph my new canoe to be christened Fayaway will also feature three mast steps or locations. I built two identical carbon fiber luff groove masts and two mains for Sylph (plus one roller furling jib) for Sylph and Fayaway will have the same. I can then sail her in several different configurations with potential sail area at just over 90 sq feet (I know that sounds like allot, it is and is only for very light air sailing). Her smallest rig set up has her sailing as a cat rig with just under 32 sq feet of sail on one mast.
So thanks for reading from a hybrid (likes his canoes light and narrow) who appreciates the comfort, load carrying ability, sleep aboard ability, stand up ability, speed under sail and paddle of the modern sailing canoe. I don't advocate one type over another or argue about boat types of designs. To each his/her own. The point is to get in a small wooden boat and get on the water. I am very pleased to have made the decision to ship one of my two canoes to England in early 2012 so that I can as the hybrid American canoe sailor share info and swap boats with folks like Brian Pearson and the Solway Dory folks who have offered to receive and store my canoe until I arrive. The idea being to share knowledge and not to espouse one type over another. I look forward to learning a great deal as I sail in England and then set off to cross the channel to Europe. Why not! Life is short and my interest in what I refer to as "Pocket Yachts" allows me to sail afar at a fraction of the cost and worry of owning a large sailing yacht. Been there, done that, what a hassle in general.
Apologies as always for the long winded posting.
