A boat hull comprises a transom and a bow; a substantially flat delta bottom surface; left and right sidewalls extending from the transom and converging to meet at the bow; left and right chines formed between the left sidewall and the bottom surface, and between the right sidewall and the bottom surface, respectively, the chines extending from the transom to the bow; and a planing area and a landing area. The chines and the bottom surface are substantially flat in the planing area. The angular bottom portions join the chines and the bottom surface. The angular bottom portions have a deadrise increasing from the transom toward the bow.
