You nailed it - just about 3kts. true w/ fluky rolling "gusts", to a roaring 7kts. ; yet I spent alot of the day on one hull slicing through the apparent wind w/ the kite !
I know there is someone out there considering the F16 for purchase and wondering if class X might not be a better choice... Hey , the F16 is it - you can't have this much fun in essentially no wind AND have a manageable rocketship in 20kts. !!!!
