文章介绍了高速艇上水翼减阻的原理以及三种不同类型的高速艇上加装水翼的技术方案及其达到的减阻效果，并给出了滑行艇首部加装水翼（即翼滑艇）后整船阻力的估算方法。基于三维非线性涡格法，建立了单独水翼/水翼组合体/多水翼系统的水动力性能理论计算方法，计算结果与试验结果吻合较好，可作为翼滑艇阻力估算中单独水翼水动力性能的计算方法。算例结果表明，文中的方法可用于单独水翼/水翼组合体/多水翼系统和滑行艇加装减阻水翼的初步技术方案设计。

This paper presents the drag reduction mechanism and regime by using hydrofoil and its effect for three types of high speed crafts. Resistance prediction method of full scale is given for planning boat with fore hydrofoil. A numerical model, based on nonlinear vortex lattice method, is developed for hydrodynam-ic prediction of single hydrofoil or its assembly. Numerical results are agree well with the test results. The method presented in this paper can be used for initial design of hydrofoil crafts.
