They way I assume it’s done is to position the “Wings” to the relative wind so that the lift vector is longest and in the direction you want to sail.
If so then you ought to be able to position them so that the lift vector is straight forward.
Although to be honest, just looking at them, they seem too small, unless of course they are in a very high speed airflow, then the lift could be substantial.
They also have to be fully symmetrical airfoils, and that also hurts performance.
Also it appears that they have a long trim tab at the trailing edge?
I assume it’s movable and maybe there to control camber?

No from what I gather, from some articles and
reviews and YouTube, the
power comes from the two boomed jibs. The masts just there to hold them up. The foils around the masts, together with a rotating mechanism of the foil, not the
mast, makes them pretty much invisible to the wind.
So the convenience of the roller reefing foresails, self-tacking, probably pretty efficient though I vaguely
recall commentary that indicated not earth shattering. Against the added complication of the foils and windage in some situations.
But no expert or personal experience, though I did like the idea and the innovation. Just wondering if anyone had more knowledge.
