What ARE other wave foils in thickness???
Coming from "flight" design, I never wanted to use thick profiles, and I think the same goes for hydrofoils.
If they are thinner and more cambered, you can have more lift and less drag, but more limited upper end at some point.
If you want "range", you make them thicker yes, but they will still be more draggy, just over a wider range.
Using a reasonably cambered not too thick (but thicker than race wings) profile, will give you the best of everything IMO, and then you can use area for "how low you wanna go", and still maintain good glide and speed if needed
"Draggy" wings in itself (really thick) is never a goal IMO, that does not make any sense whatsoever.
Better use more area, and sell a bit of low-drag by using lower AR if they gotta turn on a dime
We need some more measurements of thickness on current wave wings - eventhough they are so new that we dont know what works the best, and it will probably, like most things, be individual liking.
As I have no idea/experience about where the sweetspot for most riders on wavefoils is, 7 - 8 - 10 - 12 - 15% thickness, or?
