Patent attributes
Various embodiments are disclosed for a stepped cambered planing hull for a boat including a swept back cambered planing surface having a non-linear distribution of camber. The non-linear distribution of camber along the swept back cambered planing surface may enable stepped cambered planing hulls having high deadrise (i.e., greater than 15 degrees). The stepped cambered planing hull may include a shaped hydrofoil that generates further hydrodynamic lift by piercing the free surface wake produced by the swept back cambered planing surface. The stepped cambered planing hull may have external bottom surfaces adapted at the after-body and transom to accommodate a distinctive profile of the free surface wake produced by the swept back cambered planing surface. The stepped cambered planing hull may include an adjustable interceptor blade to regulate hydrodynamic lift at low speeds or to ensure an optimal dynamic trim angle in a wide range of speeds.
