Compound hull for electric-powered, cruiser-type vessels having a unique hard chine displacement wave form hull that recycles wave energy to minimize drag and results in lowered power requirements for long-period cruising at displacement hull speeds. The inventive hull comprises: 1) an upper hull portion having a flat bottom square transom, the bottom curve of the hull sides of which match the vessel's wave form at hull speed, mated to, 2) a bottom hull portion formed as a double ended V-bottom lower displacement hull having a constant varying dead-rise. The inventive hull requires up to 50% less power than conventional cruisers of other hull shapes, at displacement hull speed.
