Abstract
Hybrid monohull is a kind of special monohull with a built-up appendage on the bottom of the bow. The appendage can produce a large damping force (moment) which conclude obviously viscous damping to greatly upgrade the ship's longitudinal motion performance. In this study, the RANS method is used on calculating the hydrodynamic coefficients of different ships with and without the built-up appendage. By comparing with the calculating results using potential theory the viscous effect of the appendage is obvious. The longitudinal motion and wave loads of the two ships are predicted. The calculating results of the two ships are compared with each other to analyze the importance of viscous effect for the hybrid monohull. The calculating results are also compared with the model test results to validate the precision of the predicting method.
