A new simulation method is developed for simulating unsteady motions of a sailing boat on the free surface. The aim of this method is to predict hydrodynamic performances of a prototype sailing boat by CFD simulations. Fluid dynamic forces acting on elements of the boat are calculated in a CFD system and combined with the equation of motion of the boat. Unsteady motion of the free surface and body boundary is treated in a moving grid system that is regenerated in every time step. Some calculations are presented for the steady advancing, rolling and maneuvering motions.
