A new system of performance prediction simulation is developed for the design of sailing boats. The finite-volume method within the framework of the boundary-fitted, moving coordinate system is combined with the equations of motion. The forces and moments derived from the CFD computation are given to the equation of motion so that the acceleration and movement of the boat is calculated. Then the movement is treated as deformation of the grid system. This system is applied to the design procedure for a IACC class sailing boat for which steady sailing attitude plays an important role for the sailing performance.
