Formula windsurfing Fin flex

If it was more rigid it would go upwind better.

@wordreet Not so sure about that - going upwind the waterflow is slower and consequently you will want the extra vertical lift of the flexing fin to stay on the plane. Besides, making a really rigid fin is easy.

@DonPedro1990 I see what you mean about the vertical pessure from the flexed fin. Yes, the tip area will add some assistance in that way. The only problem I see is that rigidity in a carbon fin comes with extra thickness, so everything is a compromise. Extra thickness or area adds weight too, and will obviously increase drag. But the best pointing will always be from a longboard (non planing) with dagger and fin together, and obviously a specialized hull shape too. Starboard Serenity ? B¬)

I'm surprised that it flexes in that direction. Thank you for uploading this.
