  Water line \Wa"ter line`\
     1. (Shipbuilding) Any one of certain lines of a vessel,
        model, or plan, parallel with the surface of the water at
        various heights from the keel.
        [1913 Webster]
  
     Note: 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.
           [1913 Webster]
  
     2. (Naut.) 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.
        [1913 Webster]
