Sail A Boat By Water的意思|示意

With a very large outboard motor, for example, the boat may be imbalanced by having that weight far astern and may "squat" in the water and not sail as well.

例如，如果装了一台很大的舷外发动机，船只可能会因其重量而变得不平衡，尾部偏重，用俗话说倾向于在水中“蹲着”，而影响航行。

For the more adventurous, sky-skiing involves being strapped into a harness attached to a parachute-like sail, and pulled along over the water by boat.

如果想玩更刺激的，那就可以选择水上滑翔降落伞(sky-skiing)——人被绑在一个像降落伞一样的帆上，由一艘船拉着在水面上前进。

How can a boat navigate by water without sail?

船若没有帆将如何涉水航行？
