new proto foil thingy for shallow water. Designed by Lessacher so might be decent.

Can you please point us to the site you got this from. I think it's a great concept for light wind sailing.

Did it work well? Anyways it looks nice

Looks nice but having so much material cut away from the back of the base of the fin is ... interesting. I remember that one of my criticisms of fins with wings was that the lift generated was too far back, pushing the nose down. The extension solves it. I do wonder how much it ventilates, though, especially in washboard chop.

Zero..

Dunno what broke, but from what I heared it snapped on one of the very first reaches.

I love all these ideas ( and tried a few of my own ) , to get the ultimate early planing machine .
Still chasing to get planing as early as possible . So far it's a old RB with the CB removed and slot taped over . But it's a strange planing and lacks excitement.
My theory is , in non planing Conditions you can't beat long and thin .
For early planing I also think long and mid width , not short and wide.
Unless proper foiling , i dont think wings and fin concepts will be the best thing , they may help a little.
I would guess that a no rocker square edged , stretched out Fanatic Blast shape would work good with its parallel top view . It won't like chop or turning , but hey , you can't have everything. It's not like foiling is an easy option , ( although I'm just starting on this idea ) , or raceboards turn anyway. Formula doesn't work for this fat cat.
Its going to be my next project . Could end up with an expensive slug

I found it on windsurfing.nl. Apparently it snapped on the first run, too much pressure in the long horizontal tube. I'm not sure if it designed with early planing in mind, I think it was supposed to be a foil alternative for shallow water locations. Looked interesting but can't see it going into production:)
