water lines

船体水平剖面的轮廓,如漂浮在水面时的轮廓。

The outline of a horizontal section of a vessel, as when floating in the water.

船舶、模型或图纸上平行于水面、距龙骨不同高度的任一条线。半宽图中为表现各高度船体水平形状的外曲线,纵剖图中投影为水平直线。

Any one of certain lines of a vessel, model, or plan, parallel with the surface of the water at various heights from the keel. In a half-breadth plan, the water lines are outward curves showing the horizontal form of the ship at their several heights; in a sheer plan, they are projected as straight horizontal lines.

标在船体外侧的若干线之一,对应船平浮时的水面。最低线表示空载时的适当吃水,称空载水线；最高线称满载水线,表示装载时的适当吃水。

Any one of several lines marked upon the outside of a vessel, corresponding with the surface of the water when she is afloat on an even keel. The lowest line indicates the vessel's proper submergence when not loaded, and is called the light water line; the highest, called the load water line, indicates her proper submergence when loaded.

浸入水中的物体与水面接触的线。

The line corresponding to the surface of the water touching any submerged object or body.
