Gong will sell you a new G10 wing for less than 200 euro, and they are superb,
That's a price thats not to bad at all, even cheaper than many windsurfer top skegs.
But I have never had a desire to make my own gear after two of us spent loads of time and cash making a windsurfing slalom board, it sailed like a pile of Poo.
Looked crappy as well.
But I do admire it when home made kit looks good like the boards that TW on here makes.

I've looked into this deeply. Foil designers, even amateurs, are not sharing the profile details as this is a significant part of the magic juice and IP. Yes, there's a lot of other interrelated design parameters, but the profiles are the starting point.

In the surfboard world, they cannot hide outline shapes and they are easy to copy, but no one is publishing rocker curves, bottom sections and fin placement dimension details. This again is the secret juice they try to protect.

The companies in China that are stealing, just buy one of them, 3D scan it and reverse engineer, cutting invisible corners to save cost and navigate their own production inadequacies.

just to mention - I don't work in the surf industry (I'm an environmental engineer). but I do my own surfboards windsurfboards kiteboards snowboards skateboards kiteboards foilboards foils since
1982, just for the fun of it. must be 50 or more boards meanwhile.
Before and parallel I also did a lot of model airplanes.
On the water I also use equipment that I buy. For examle levitaz kitefoils.
the foil wing I want to make now is something that can't be bought anywhere right now, it will be a huge 3300 cm2 pump foil wing that gives me
the same surface weight ration like my friends that pump with the go foil maliko 280 and are much lighter than me.
I would not ask Go for the profile - I understand that they won't give it away.
Meanwhile I know pretty much about the profile that is used, I will find something very similar it is not difficult...
