Using traditional strip method to predict longitudinal motion of hybrid monohull, the results are very different from test results, it can not reflect the effect of built-up appendage by reason of ignoring viscous force. This paper calculated the hydrodynamic coefficients of the hybrid monohull with two correction methods, one considering the viscous effect with lateral flow theory, the other calculating the correction coefficients based on RANS equation by using FLUENT software, and then predicted the longitudinal motion by STF method. By comparing the predicted results with the model test results, it shows that, both of two correction methods can reflect the effect of built-up appendage, and can be used for predicting the longitudinal motion of hybrid monohull, the accuracy of the latter is obviously better than former, it has good value in engineering application.
