In Europe and USA, high speed trimarans are regarded as one of the candidates of future high speed vessels for fast sea transportation. In the present paper, free surface flows around a high speed self-propelled marine target system which has a configuration of trimaran are analyzed by using Rankine source method. Since this trimaran has huge transom sterns, however, Cheng's scheme should be introduced in ordinary Rankine source method in order to simulate the free surface flow after those transom sterns. After discussing numerical procedures, numerical examples are shown and optimum configurations of outriggers are discussed for this trimaran target system. For this purpose, colored wave patterns simulated by the present method are compared for several cases of configuration.
