Having sailed a moth for a few years now, Wouter your T-foil solution won't be reliable. Once a boat is on foils, the pivot point for righting movement is now all on the foil as opposed to being on a 16ft hull touching the water. The foil has to be super strong and can't flex at all. Part of the reason why a Mach2 is faster than a Bladerider is due to the Bladerider foils flexing where Mach2 does not. Plus many many bladerider foils broke due to the loads. The mach2 foil can have a person jumping on them when suspending between 2 benches without any concern at all. And this is the lengths needed for a 30kg boat. Imagine now a boat that is 107kgs and has 2 persons onboard. Breakage city if not done correctly.

The other thing is that there can't be any slop in the system. Has to be rigid. The lengths we go to minimise slop is quite extensive. Reason is that slop means loss of control.
