I sail a Maricat 4.3 which is a Hobie 14 eqiuvalent. This is on my list of fun things to do when I have time.
How did you attach kite to boat? One kiter and one skipper or do you have lots of arms? Is it possible to tack or do you have to jibe?
The proa I'm building would be a pretty good kite boat, being bi-directional.
