I am thinking the speed advantage from flying a hull is the decreased wetted surface as a result. I think the whole foiling aspect of these boats makes this a mute point. My guess is my 19 foot kayak has more wetted surface than these boats when foiling.
I went back to re-watch this video. It is amazing to watch them scramble back and forth obviously working some sort of lines. But I can't see a single thing moving on the sails. It looks like the jib may be self tacking and I can't detect any movement from the wing. It looks like they just start cranking on the winch and the boat steps up on the foil and takes off. Maybe they are not controlling lines with the coffee grinders maybe they are winding up a huge rubber band.
Even the tactics and the boat movements seem totally foreign to me. The only thing I could tell for sure was when the upwind foil went down they were going to tack.
