The prediction of full ship＇s maneuverability hydrodynamic forces is not only the basis of form/ configuration optimization in maneuverability design but also the difficulty of the prediction for maneuverability hydrodynamic forces of surface ship. In this paper, the accuracy of CFD （Computational Fluid Dynamic） in maneuverability hydrodynamic forces prediction was investigated, then the CFD computation and the analysis of experiment validation were applied on a series of full ship,The results show that the numerical model can give good accuracy and be widely used.
