thanks, really interesting!!

So if I'm not mistaken
upwind --> boards all way down --> enable to pivot the lower end of the board backward --> the CENTER OF LATERAL RESISTANCE move backward

downwind --> boards halfway up --> no pivoting --> the CENTER OF LATERAL RESISTANCE move a bit forward

All together could effect a neutral helm both upwind and downwind... (what the infusion really has)

??

I will check my dagger boards.

I sailed my infusion only a few times (5-6), and realized that the trailing edge of the boars can be damage really easily even nothing was happened during the sailing, probably because of this pivoting ability.
