Load waterlines can be described using various synonyms such as draft, immersion, submersion, and load displacement. Draft refers to the depth of a ship's underwater body, which is the distance between the waterline and the deepest part of the hull. Immersion pertains to the degree of submersion of a vessel's body below the water surface. Similarly, submersion denotes the act of sinking a ship or submarine into the water. Load displacement, on the other hand, refers to the total weight of a ship and its contents, including fuel, cargo, and crew, which causes the water to be displaced and determines a ship's buoyancy. All these synonyms are commonly used in the maritime industry to describe a vessel's load waterlines.
