Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weig ...

Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water

While there were minor differences between the four ''Batillus''-class ships, they all approached a gross tonnage (GT) of 275,000 and tonnage, and had a length overall of over (longer than all but a few of the tallest skyscrapers in the world).
