不就是和舭龙骨一样作用的吗？bilge keel舭龙骨的翻译。

Ship stabilizers are fins mounted beneath the waterline and emerging laterally. In contemporary vessels, they may be gyroscopically controlled active fins, which have the capacity to change their angle of attack to counteract roll caused by wind or waves acting on the ship.

The "bilge keel" was an early 20th century predecessor, although smaller and not as effective.
