A keel also provides weight low under the water to lower the boat's center of gravity below the waterline, which is needed so that the boat bobs back upright if knocked over by wind or waves.

龙骨同时也增加了船只的底部重量，从而将船只重心降到吃水线之下，而这对于船只在被风浪打翻时能够得以及时回正是十分必要的。

They found that gravity waves "break" on the surfaces of planes, just like ocean waves breaking on the beach, causing much of the turbulence that occurs out of the blue in clear air.
