Bob,
Just a suggestion:
Limit the circumference of the mast to 500mm so we don't end up with solid winged sails.

Ulimately if you have to be grossly inconvenienced to own the fatsest boat. There will be a very small group of people willing to put up with it and the rest will find something else to sail.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
