This paper presents a method to calculate wave patterns generated by an Air Cushion Vehicle (ACV) with constant forward speed on the calm water surface. For that purpose the Panel Shift Rankine Source Method is adopted. In this calculation method, the numerical treatment of the step change of cushion pressure at fore and aft edges of cushion field is discussed. 2-dimensional and 3-dimensional computations of wave patterns, profiles and the wavemaking resistance are carried out. Computed results show good agreements with the analytical results. The present method can be utilized for estimating the wave height distribution inside the cushion area, especially at the aft-skirt positions. This information is important for designing or modifying the aft-skirt system of ACV which sometimes causes large scoop drag.
