Roll-on/Roll-off Ship

A roll-on/roll-off ship, commonly abbreviated RoRo, is a cargo vessel built with large ramps and open internal decks that allow wheeled cargo such as cars, trucks and trailers to be driven directly on and off under their own power rather than lifted by crane. The design greatly speeds loading and unloading compared with traditional break-bulk cargo handling, and RoRo vessels have become the standard means of shipping new automobiles and other wheeled freight across oceans and along many short sea and ferry routes.
