REVOLVING CATAMARAN

The Revolving Catamaran (rCat) is an asymmetric catamaran, incorporating the aerohydrofoil invention... Even if speed drops to zero, the mainhull keeps turning around its center, because there is no counter torque from the side-hull, nor from the sail drag... Side-hull, with slack sail, are revolving freely around mainhull vertical hinge, to the new position. Without affecting the turning of mainhull.
