More lift = more drag, so it might be drier but it won't be as fast as a VDH for the same power and weight. Just like on airplanes, the more you deflect a fluid, the more lift you'll get, but you'll also get more drag along with it, unless you can do something clever to improve the L/D ratio. Moesly's idea with the VDH was to improve L/D by deflecting the water from the keel to the chine as gradually as possible, while also introducing a boundary layer of air to reduce drag. His testing proved that it worked, producing a hull that was about 10% faster for the same power and weight as a conventional constant deadrise hull with flat strakes!
