Propellers commonly referred to as screws cut through the water and provide forward or reverse motion. Unlike airplanes which require tremendous propeller speeds to provide the forward motion needed for flight cruise ship propellers do not need to turn as fast. These propellers measured 23 feet and 6 inches and weighed 38 tons each.

With a pod system the equivalent of the propeller shaft and the drive motor are located within the pod not in the hull.

The distance the ship is propelled forward in one propeller rotation is actually less than the pitch.

Unlike airplanes which require tremendous propeller speeds to provide the forward motion needed for flight cruise ship propellers do not need to turn as fast. Royal Caribbean Quantum-class cruise ships propulsion In April 2012 ABB made a USD 60-million contract to provide the Azipod propulsion systems for the new Royal Caribbean ships of the Quantum-class Quantum Anthem Ovation and Quantum.
