Fin development for kite racing

San Francisco Bay may be ground zero for kite racing, with this report from waterhound.com profiling the work going on with fin set-ups:

With all the work around fin set-ups there seems to be a consensus that next year we will see 3 fin set up as the mainstay. One big fin in the center and two smaller thruster style fins. That said I took a few shots of the various fin set ups and posted them below. There is a quite a variety and you may recognize many Formula Windsurfing Fins being utilized. A lot of the riders have been taking old Formula fins and cutting them down. I am not sure who donated the two Techtonic Fins in the first photo but that was a crime. Those were still good fins!
