[python] Sailing Python - Basic frame layout done

thought I give a short update.
I have finished the basic frame of the sailing python.
Pciture of Frame

The basebracket, drivetrain, seat and sail are still missing.
The wheelbase is now only 102cm (3ft). All wheels are 20".
The only concession to the sail yet visible is the 130cm (4,2 ft) track. Seeing it in reality, I have some concerns about the usability. Going on cycle lanes will be more or less out of question. I guess I will try how it works out and might reduce the track later as needed.

The idea behind this is a python with an additional source of proposition. Since the scope is to run it under street conditions, the sail arrangement need to be secure and simple. The goal is not a sailing cart to be run on a beach.
At the moment I think about:
*Cat Sail (without boom)
*Flettner rotor

Best regards

Hello all
About sailing and about proas, I found this one a few years ago (http://proafile.com/view/weblog/comments/palindrome_a_land_proa/).
I suppose it's the closest approach to a land proa, and seems to be very fast, despite the fixed mast.
I also built something like I think a proa should be (http://almaanegra.blogspot.com/2008/11/noire.html).  I never tried it with a sail, just paddled it several times and found it to be very very very hard to change track - as I said, as a proa should be, because it has to handle very strong lateral forces. And I believe that a python's most distinctive characteristic (the strong negative trail) should be very hard to handle with strong lateral forces - in a proa-like or any other configuration; Unfortunately you are supposed to spend almost all your sailing time dealing with this lateral forces. I suppose some previous experimentation should be done prior to building a very nice but completely unpratical machine.

Did anybody try already try to sail a python?

Guess it would have to be a three weel configuration?
Did you see this sailing trike http://www.whike.com/en/ . Maybe you
can get some inspiration about sails here http://windskate.com/
