Sorry, Peter, not all over the world.
In older part of it there are some needs and tips.

I am not crazy particular about most hydrofoil stuff, it all seems to work, mostly just design. I sand to about 320 and lose interest usually. I have been fixated on the rear stab angle forever, but there must be more!!!!
I have done some flawless paint and fill jobs with 2 part poly car primer, it feels great on a perfectly tuned foil! I'll probably do it again someday but not totally my thing
Lately I have had the front wing AOA revelation, yes revelation, to get me in the ballpark of my footstrap locations which only adjust 4 inches. I am looking forward to trying to tune some foils! in warm water
You can make shims anywhere carefully with tape and cans and plastic , I have some fiberglass 1 and 2 degree shims
I understand shimming is not necessarily a regular thing but it is essential to tuning your ride. I do it a lot . I assume some other people do this right? Commercial foils aren't set up perfect out of the box for everyone are they? I also understand some wings are not shimmable.
If you want to be drastic you can sand camber into your lower surfaces , tips on the stab, root on the main wing! I don't recommend this but it's noticeable.
1 AOA rear wing relative to front wing
2 AOA front wing relative to baseplate/box
3 Sanding smooth
4 filling and painting
After sanding you can wipe epoxy on and then wipe thoroughly clean and it with impregnate the fibers nicely.
Please share if you have any thoughts or routines on tuning your ride
Tips , experiences, failures , successes ?? how do you tune?
Since few hard crushes, I tune my foils (Zeeko) to slow max speed and deacrease foil drag at lift off at the same time.
I shim front wing to increase its AoA, leaving stab as it is.
This way fuse travels at negative AoA at higher speeds = more drag = lower max speed.
At low speed fuse travels at AoA close to 0 = less drag = better low limit. (I presume foil producers calculate min fuse drag at max foil speed).
Helps in waves and if you retire
Improves jumpig ability a bit as well
I shim mast plate to make my both legs are bent at the same angle. This will reduce pain in front or rear leg.
Was important at my 365km long one day run.
For jumping I shim stab to make the foil quick at lift off.
If to much FF pressure, move straps forward.
It adds another meter or two to my jumps.
