Underwater wings called hydrofoils help lift the sea glider, reduce drag and allow for a smooth ride above the waves.

被称的下机可以抬升海上滑翔机，减少阻力，使其在海浪上方平稳飞行。

It's only 20 minutes away by hydrofoil.

乘坐只需20分钟即可到达。

When it's time to take off, the hydrofoils retract and the sea glider won't fly within a wingspan of the water surface, benefiting from an aerodynamic principle called ground effect to glide along a cushion of air.

当起飞的时候，会缩回，海上滑翔机不会在面的展范围内飞行，这得益于一种叫做地面效应的空气动力学原理，即沿着气垫滑翔。
