Hybrid-monohull is a kind of high performance ship which can reduce longitudinal motion by adding viscous and lifting dampinging. It has been proved that it can sail steadily with high speed in waves. The prediction results of hybrid-monohull using strip method based on potential theory can´t reflect its reducing effect. The reason lies on the ignoring of viscous effect. However viscous dampinging plays an important part in total dampinging, so the dampinging coefficients have to be modified. In this paper the hydrodynamic coefficients of bow where built-up appendage is fixed will be calculated using 2-D and 3-D viscous fluid numerical methods. And RANS method is used for calculating the lifting dampinging of built-up appendage. The calculated results indicate that the method used in this paper can reflect the reducing effect obviously, and the precision of prediction is much more improved. The the prediction precision of 2-D method is a little worse than 3-D method. In one word, the method based on viscous hydro-coefficients calculation can predict the motion of hybrid-monohull efficiently.
