Regal Boats has been doing that idea for years with their Fast-Trac hull. It basically uses some slots in the hull, cut in at about a 45* angle outward from the centerline. The thought is that the water becomes turbulent and creates bubbles as the water passes over the slot.
I don't know how much it adds to the efficiency of the hull.
