Would a nice compromise not be to rule that it may not be possible that the angle of the T-foils relative to the hulls is adjusted while racing ?

Thus allowing adjustment between races and still leave the room for experimentation open without the fear of rising costs as there is no need for expensive control system when you can't adjust them while racing (sailing).

This is also the way we adressed the fears that were around a while back about systems that could rerake or heel the rig towards the wind while sailing/racing. Now people have only staymasters on their boats so they can adjust the trim in the break between races but not during races. This has proven to allow maximal adjustment of trim without adding any real costs.
