A finite-volume method is applied to a problem of tandem hydrofoil advancing beneath the free surface. The curvilinear grid system is fitted both to the free surface and to the hydrofoil surfaces which moves by the wave motion and ship motion respectively. It is demonstrated that such simulation technique is useful for understanding of hydrodynamical properties of system with moving boundaries and that it can be practically used for the design of hydrofoils with flaps and associated control system.
