Calculation of the resistance and trim of highspeed boat at planning regime is a complex hydrodynamicproblem. At the planning regime, with the aid of liftingforce, the boat is lifted over the water surface with hightrim angle. Many methods have been applied to calculatethe resistance and the trim of the high-speed boat at thisplanning regime. This paper will study the two typicalmethods, the first one is empirical method by Savitsky [1]and the second one is the computational fluid dynamicmethod (CFD). The calculation results of two methods arecompared with experimental results.
