To accurately estimate the hydrodynamic performance of planing craft in waves, the high-speed sailing of planing craft in regular head waves was numerically simulated with multiple degrees of freedom by performing seakeeping model experiments． In the simulation，the FINE/MARINE software was adopted and the body-fitted mesh technique was employed． The numerical results were then compared with the experimental data to verify the accuracy of the simulation．It is found that the numerical simulation can accurately and efficiently simulate the motion attitude and the hydrodynamic characteristics of the planing craft in high speed navigation in waves. Based on the time domain and frequency domain analysis method of the motion responses of the planing craft, the analysis of the influence of the period of incident wave and the natural frequency on the response of planing craft has been finished, which provide guidance and reference for the design of planing craft.
