BUT...wouldn't the T foil rudders be working against the curved plates? Unless they were trimmed to lift the back of the boat. I was under the impression they (T foil rudders) are there to keep from pitchpoling, or are you saying the whole boat should be a foiler? That would be very nice to see!
T foils to prevent "sailing over" the curved plates.
a 20 x 12 or 13 platform is going to create a LOT of drive down wind. The big stuff it's going to be a challenge to keep the mast out of the racetrack.
