Compared the 2019th and 2020 Wizard. THe 2019 is quite totally flat in the bottom.
The 2020 has deep double concave.
The 2019 sticks on the water and doesn't want to glide.
The 2020 is getting much more speed and gliding phase. Feels much looser on the feet and starting then flying earlier. Easier to pump better to controll on touch downs.I gues this effect will be archived also with the cut outs. But this only basing on the expereince with the comparsion of this two boards.
So you had a chance to try the 2020 Wizard? Or is this based on what others said?
Anyway, this points to interesting differences between the optimal underwater shape for windsurfing and foiling. In windsurfing, too much underwater structure (double concave or similar) increases surface area and friction. Hence the flat rear bottoms of slalom and speed boards. But for foiling, the board needs to unstick from the water. That's actually harder with a very flat bottom shape. Wing boards, with almost kayak-like rails and often deep concaves, are an example. The shape reminds me a bit more of D2 boards than of planing windsurf boards.
Yes I flight first the 2019 for round 50 session then the 2020 for round 20 sessions.
The basic form is identical, but the underwater shape is completely different with a deep double concave.
This helped extremely to get the board free from the water. I can not say sure if this helps to get it flying a half or one knot earlier. But it feels sometimes so.
