针对滑行艇耐波性预报必须考虑水动升力影响导致常规方法不适用的问题，采用基于线性长波假设的方法，考虑了瞬时波面对各水动力系数及波浪载荷的影响，给出了棱柱型滑行艇在规则波中迎浪运动响应的时域解。同时，在计算瞬时水动力系数和波浪载荷时也考虑了升力效应。通过简化处理，将其应用于常规滑行艇的运动预报，并通过模型试验结果进行验证，计算值和试验值吻合较好，有较高的实际应用前景。

The conventional method for sea-keeping prediction is not applicable to the planing hull because the cal-culation is difficult if not considering the hydrodynamic lift in waves. Based on the linear long-crested wave assump-tion, and considering the influence of transient wave surface on hydrodynamic coefficients and wave loads, the time domain solution to motion response of a prismatic planing craft in regular head waves is presented. And when calcu-lating transient hydrodynamic coefficient and wave load, the effect of lift is also taken into account in the simula-tion. It is applied to the prediction of conventional planing craft after some simplifications, and the theoretical cal-culation was validated by the model experiments, and the agreement was found to be pretty good, thus, proving that it has good application prospects.
