Sounds like very interesting stuff! If the project goes awry, remember your emergency exit: Build the blades out of cold moulded wood veneers with a 7% carbon laminate added. Should solve the problem you are trying to fix <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
Or drop the thing into the ocean where the currents are more predictable and not so violent. Of course, just dropping it into the deepest part of the sea would also solve the problem, kind of..

Good luck with it! If I see such systems in production in 10 years I'll let everybody around me know that the guy who designed that system also sail catamarans.
