A vessel’s load line length is measured on a particular waterline, determined by its molded hull depth (the vertical dimension from the top of the keel to the underside of the freeboard deck at the vessel’s side).
Why do ships have multiple load lines?
Purpose : They are used when, for a period of time the vessel has to operate temporarily with a greater freeboard in accordance with the International Load-Line regulations. – A number of ports have special requirements for maximum draft and deadweight for ship’s calling at them.

The AC load line is a straight line with a slope equal to the AC impedance facing the nonlinear device, which is in general different from the DC resistance. The ratio of AC voltage to current in the device is defined by this line.
What is a freeboard?
Freeboard is the distance measured from the waterline to the upper edge of the deck plating at side of the freeboard deck amidships. Ships must have a load line mark located amidships on both sides to indicate the maximum allowable draught under specified conditions (geographical and seasonal).
