Gross Tonnage represents the overall internal volume of a ship, not its weight. It is calculated by measuring all the enclosed spaces of a ship and using a formula established by the International Convention on Tonnage Measurement of Ships. Calculation: $GT = K imes V$, where $V$ is the volume in cubic meters and $K$ is a variable figure based on the volume.

Net Tonnage refers to the volume of revenue-earning spaces on a cruise ship, usually the spaces available for passengers and cargo. Calculation: Derived from the Gross Tonnage after subtracting the spaces not used for passengers or cargo.

Berth capacity indicates the number of beds available for passengers aboard a ship. Calculation: Total number of beds (fixed and pullmans) available to passengers within cabins.

Double Occupancy is the standard measurement for passenger capacity assuming two passengers per cabin. Calculation: Total number of cabins multiplied by two.

Maximum capacity is the highest number of passengers a ship can accommodate when all berths, including pullmans and sofa beds, are occupied. Calculation: Sum of all fixed beds, pullman beds, and convertible sofa beds.

Space Ratio is a measure of how much space per passenger is available on a ship, indicating the level of crowding. Calculation: $Space Ratio = \frac{Gross Tonnage}{Double Occupancy Capacity}$.

Crew-to-Passenger Ratio gives an idea of the level of service on board, indicating how many crew members are available to serve each passenger. Calculation: $Crew-to-Passenger Ratio = \frac{Number of Crew Members}{Double Occupancy Capacity}$.
