The technique for predicting the added resistance for a SWATH ship advancing in head waves is presented in the paper. The nonlinear hydrodynamic force theory and the strip theory with viscous effect correction are used. Basically the nonlinear theory used in the paper originates from that of single ship and the hydrodynamic interactions between two hull bodies are also included. Three basic assumptions are made: (1) the hull body is a "wake scatterer" (2) the second order potential is small and can be neglected(3) the ship motion is based on the linear strip theory but includes the viscous effect. According to the present study, it shows that the previously developed nonlinear theory for single ship may be applied to predict the added resistance of a seagoing SWATH ship.
