WebThe displacement or displacement tonnage of a ship is the ship's weight. The name reflects the fact that it is measured indirectly, by first calculating the volume of water displaced by the ship, and then calculating the weight of that water. By Archimedes' principle, this is also the weight of the ship. Displacement should not be confused with other measurements of … WebDividing the total underwater hull volume by the volume per unit weight of the fresh, brackish, or salt water in which the ship is to run gives the weight of water displaced. This must equal the total weight if the ship is to float at the designed waterline.
