The effect of the submerged high speed vessel on the ocean wave is made clear in the point of hydrodynamics view. In connection to the design of high speed ship, the flow analysis is carried out to predict the pressure distribution for drag and lift. The purpose of the research is to help the preliminary design of the economic hull form advancing under the ocean wave by estimating the resistance performance and the wave behaviour. In the present study, more efficient numerical approaches are investigated for the viscous flow analysis around a submerged NACA0012 hydrofoil with the laminar and incompressible fluid. Through the numerical simulation, it is found that the new numerical method becomes more efficient primarily due to the fact that the wave elevation is reasonably developed.
