RE: Revolution in windsurfing
There's a lot of difference between 8 and 14 knots of wind.
I can begin to jump and do most fun on my Aero 127 in 14 knots (steady) with a 7.5, but won't be near having fun in less than this.
I'm heavy at 97 kgs. I guess many light weight (below 75 kgs) freestyle sailors can have fun in 12-14 knots.
4 knots is not even formula planing..
Anyway the idea is amazing and I guess Starboard have a solution for having (real) fun in 4 knots within a few years.
