The boat hull includes a bow, a stern and a bottom surface which extends from the bow to the stem. The hull includes a bottom surface with a deep-V shaped portion extending from the bow to a hull point which is aft of the mid-point of the bottom surface, approximately two-thirds thereof. At least two steps, referred to a s flat steps, are included in the bottom surface of the boat, between the hull point and the stem. The steps extend across a portion of the bottom surface. Flat pads extend from each st ep to the next step or to the rear of the stern. A decrease in the size of the entire hull, referred to as a hull step, occurs at the second or third step in the bottom surface of the boat.< /SDOAB>
