DWT (Deadweight Tonnage)

Deadweight Tonnage (DWT) measures the total weight a ship can safely carry when fully loaded, including cargo, fuel, crew, and supplies. It reflects the ship's capacity without considering its own weight (lightship weight). DWT is used to understand the ship's size and freight-carrying ability, helping to determine how much the vessel can transport securely and efficiently. Essentially, it's a key indicator of a ship's cargo-carrying capacity and plays a vital role in shipping and logistics operations.
