The word "waterline" generally refers to the line where the surface of the water meets the side of a boat, ship, or other floating object. It is used in the context of marine activities such as sailing, boating, or fishing. For example, when a boat is loaded with passengers or cargo, the waterline can change, affecting its stability and speed. Waterlines are also used in engineering and architecture to indicate the level at which water should be contained or diverted in various structures such as dams, canals, or drainage systems.
