Deadweight


Deadweight (DWT) is the total weight of cargo, fuel, provisions, passengers, and crew that a vessel can carry when submerged to a certain load line. It is the difference between the displacement of a ship in water when it is empty and when it is fully loaded. Deadweight is an important factor in determining a ship's carrying capacity and is used to calculate various performance metrics such as speed and fuel consumption. It is also a key consideration in determining the fees charged by ports and canals for the use of their facilities. Deadweight is typically measured in metric tons (MT) or long tons (LT).
