英汉例句

• The centerboard trunk takes up space in the boat's cockpit or cabin.

  活动龙骨舱需要占据船只驾驶舱或卧舱的空间。

• A popular trailerable centerboard sailboat is the MacGregor 26, which with its water ballast has the advantages of centerboard boats but not all the disadvantages.

  MacGregor26是一艘很流行的可拖载的活动龙骨帆船，它自带的水压载系统(waterballast)使其具有活动龙骨帆船的所有优点，并避免了部分缺点。

• Most centerboard boats can be trailered and easily launched and hauled out on boat ramps (larger centerboard boats may require deeper ramps).

  大部分活动龙骨船只可以被拖车运载，并很容易通过船舶下水滑道(boatramp)放入水中(当然，大型的活动龙骨船可能需要使用更深的滑道)。

• The centerboard usually hangs down below the hull from a pivot at one end.

  活动龙骨通常悬挂在船底之下的某个旋轴上。

• On centerboard sailboats, the centerboard functions like a keel to keep the boat from being blown sideways.

  在使用活动龙骨的帆船上，活动龙骨的功能和固定龙骨一样，是防止船只被吹打得侧晃。

• The centerboard can be partially raised if needed to provide better boat balance.

  可以通过部分提起活动龙骨板来更好的控制船身平衡。

• Finally, some historic craft have leeboards instead of centerboards; these boards, mounted outside the hull on both sides, can be pivoted down like a centerboard to resist leeward motion.

  最后，一些历史上着名的船只使用下风板(leeboard)取代活动龙骨板；这些下风板悬挂在船只底部的两侧，可以像活动龙骨板一样被放下来以抵抗侧向晃动。

• The centerboard can be raised to decrease displacement to allow the boat into shallower water - and it should swing up and back if it hits the bottom when sailing with it down.

  当船只需要进入浅水区域时，活动龙骨板可被提起，以减小船底深度——即使不将其提起，它在船只行驶中触碰到水底时也会来回上下摆蕩。

• If the centerboard is not weighted, like the fiberglass centerboards of many small sailboats, then sailors must keep the boat upright by positioning their own weight on the upwind side of the boat.

  如果活动龙骨不带负重，例如许多小型帆船使用的玻璃纤维活动龙骨，那么水手们必须通过将他们自己的体重压在船只的逆风侧来保持船只直立。

• The centerboard can be raised for faster downwind sailing

  在顺风航行时，可将活动龙骨板提起，以减少阻力，加快航速

• Shallow draft centerboard vs. deep fixed keel - trailerable vs. launched by boatyard.

  浅吃水的活动船板帆船vs深吃水的固定龙骨船？ 可用拖车载运的船vs 要拴在船坞上的船？

• If the centerboard is weighted, then it also provides weight low in the water, like a keel, to help keep the boat upright (although not as much weight as a fixed keel can supply).

  如果选用了带负重的活动龙骨，那么它和固定龙骨一样提供水下的重量负荷，以使得船只能够保持直立(尽管它无法提供和固定龙骨一样大的重量)。
