Stepped planning hulls are commonly used on fast planning boats and water-based aircraft, but numerical means for simulating their hydrodynamics are rather limited. In this study, a panel method involving hydrodynamic sources has been applied for modeling a stepped planning hull and accounting for water surface deformations in the air-ventilated cavity and surrounding water domain. Parametric calculations have been carried out for a selected hull with variable deadrise angles and at two speed regimes. Results are shown for the boat attitude, lift-drag ratio, and drag components. The variations of the wetted surfaces on two bodies of a stepped hull are also presented and related to variations in hydrodynamic characteristics of the hull.
