Yeah, if you look closely at the bows of the cat vid. I posted above, you'll see they are shaped like the hulls on a float plane, fat and flat forward, with a step half way back. They are designed to be sailed flat, on two hulls, and get up on the 'step' to plane as soon as possible, and reduce drag that way, rather than by flying one hull. BUT...in light air, I think those hulls would be very slow.
