Displacement is calculated as DWT plus which weight?

• A. Lightship
• B. Cargo
• C. Fuel
• D. Stores

Answer: (A)

Displacement is the total weight of the ship, which consists of its own weight plus everything it carries. Lightship is the ship’s own weight with no cargo, fuel, stores, or ballast. Deadweight tonnage (DWT) represents the additional load the vessel can carry beyond its lightship—cargo, fuel, stores, crew, and so on. So, to get displacement you add the deadweight to the lightship. In other words, displacement = lightship + DWT. Cargo, fuel, and stores are part of DWT, not separate additions to it.
