In the provided notes, DWAT is equated to which term?

• A. DWT
• B. Lightship
• C. Displacement
• D. Payload

Answer: (A)

DWAT is essentially another way to refer to deadweight tonnage—the weight a ship can safely carry beyond its own light ship weight. In practice, this means DWAT equals the difference between the ship’s fully loaded displacement and its light displacement, expressed in tons. That carrying capacity includes cargo plus fuel, stores, ballast, crew, and passengers as applicable, but does not include the ship’s own hull weight. Lightship is the ship’s weight when it has no cargo or stores, so it’s not a measure of carrying capacity. Displacement is the total weight of the ship at a given condition (the weight of water displaced), which changes with load; it’s not the carrying capacity by itself. Payload typically refers to the cargo portion of the load, whereas deadweight includes additional items like fuel and stores. So the notes’ equating DWAT with DWT aligns with understanding deadweight as the ship’s cargo-carrying capacity.
