Interesting.  So the main difference between the original Takuma wing and your prototype is a thicker leading edge?  You did not change the surface area of the wing?

Leading edge and bottom profile area is almost the same.

all so trying printing a shim plate that can go on the takuma to change the mast angle. (low quality with low infill just as a test)

Here we go printed angle base plate, thinking I may remove the outer edge as it's not really needed. This one is a 3mm rise at the back to bring the nose of the foil up.

When I was looking at foils, I felt that the mast-plate attachment method is superior because it could be shimmed for angle.  Too bad the go-foil isn't available with a mast-plate.

yes until a better idea comes along the plate mount is the way forward especially if you bolting up to a board that has not been specifically designed for a particular foil. The adjustment are so small but make a huge difference. I normally take a alen key out with me and some shims and play around most sessions or at least every time I change boards or wings ect.

For what purpose? I don't surf so I don't know. It shouldn't matter once you are up so I assume it is to optimize paddling-out or lift-off, ie the attitude of the foils while the board is still in the water.

That's nice man. Really pro touch putting the logo and dimensions in it. Also great when you are trying to remember which one you want.

You are really making a case for the plate mounts for sure.

Got a bit of a idea to try something and just wondered does anyone know what grade of cineseium would be being used in the masts and fuz of the foils that are being made or what would be most suitable ?

UK, you thinking of aluminum? I have a buddy who could help with that selection if so.

What is cineseium? Do you mean aluminum? Are you considering extrusions or built up? All the aluminum masts I've seen are extrusions, probably 6060 T4. That's the most common extrusion alloy because it extrudes so nicely and it can be solution hardened to T4 state as it comes out of the extrusion die. I saw one that looked to be a 1000 alloy because it was so soft and weak.

I considered doing a built up, because I can do that myself, but shitcanned the idea. I'd either do carbon or buy the mast rather than that. I started to build a carbon mast using a broken Ke Nalu paddle shaft as a core. I might finish that someday.
