The practical application of hydrofoil shows that, when hydrofoil sails in oblique wave, the "full submerged" hydrofoil performance is superior to the piercing hydrofoil performance.
水翼船实船使用表明，在斜浪作用下，“全浸式”水翼船的运动性能明显优于传统的“割划式”水翼船。

The nonlinear free surface boundary condition is considered and the hydrodynamics forces of the hydrofoil near the free surface are calculated by the submerged vortex lattice method.
