A method of controlling the attitude of a boat at high speed through boat hull design involves a first step of forming a pair of high speed steps in the hull of the boat. The pair of high speed steps provide enough surface area to control ride attitude, while reducing the wetted area of the hull to decrease drag. A second step involves forming transition steps to provide a transition to the high speed steps as the boat accelerates. In addition to reducing drag, the method aids in turning and lifting of the hull by trapping air and water in the steps.
