Here's what I've been wondering ever since this foiling thing came to the A Cats, once you are up on the foils, hull length no longer applies for speed, so the real challenge comes to be how much sail area you can control, and how efficient your foils are, right?

Perhaps once all cats start foiling, a new measurement rule will evolve that only looks at total sail area, total foil area, and minimum weight?

Hull length, and maybe even beam, won't matter as much once you are up out of the water.
