The present paper studies the numerical methods for predicting ship's maneuvering hydrodynamic forces and proposes an improved numerical procedure. To improve such numerical methods, the effects of separation position, the initial vortex position and the shedding angle on the lateral force distribution have been studied in several separation models. The effects of body's section number and the frame's mapping parameter number have also been discussed. In the improved procedure the theoretical solution for the ellipsoid is adopted to revise the force near the bow. The calculated forces for 4 ships by the procedure agree with the measured data satisfactorily.
