Clearly they have relocated to the U.K. since I made the post

VERY VERY basic sketch but, just showing the configuration.

Trapeze so can quickly adjust trim

Cotswit was a painful process, especially the years of argument as to where the boundaries actually are.

These foils look great for an amateur builder of floating boats, but a bit heavy to fly?

In a sailing dinghy you need the foils to resist side loading if you want to go upwind with any efficiency. In this case if the boat is flat both sides are cancelling each other out which is fine for a power boat but not for a dinghy. If you heel it to windward then the leeward foil provides the side force and the windward one provides the lift. Given that this reduces the righting moment from the crew this is not a fast look. Also this is why the RS600 foiler did not work too well in that trapezing off a boat heeled to windward is not to easy or comfortable. Back to the drawing board I think.

This configuration was used on many record breaking craft from the 1950s until the recent past. The windward foil is naturally immersed more and a vertical portion on the foil tip is sometimes added. I simply presented a very simple configuration that is well proven and simple - which was my reading of the OP ‘ easier to sail platform like the Skeeter would make the boat more accessible to more 'normal' sailors‘

It is on a catamaran which makes quite a lot of difference. There is a reason a moth looks the way it does.

And costs as much as it does, I am just pointing out that there are other solutions other than wands and incidence control. One of the first foiling moths used this system. Yes they went a different direction but that could have been driven by fitting the concept into the class rules rather than the system.
