Fin angle
The toe in on surf board fins is wrong for the speed and angle that a kiter rides a surfboard at. This is why kite surfboards have less toe in than surf surfboards.
Kiters are fighting the surfboard fins while they are kiting back upwind. This is why surfboards tend to flap around going back upwind. The fins are creating lift and trying to lift the tail out of the water, while the kiter is trying to keep the rail and fins in. If the fins are toed out more, this effect is reduced.
Possibly change the angle of the fins
or
A much smaller centre fins feels better
I played around a lot with the fins on my board...and the little fin at the back works a treat.. and if the swells small even take the back fin out..
