Roll-on/roll-off (RORO or ro-ro) ships are vessels designed to carry wheeled cargo such as automobiles, trucks, semi-trailer trucks, trailers or railroad cars that are driven on and off the ship on their own wheels. This is in contrast to lo-lo (lift-on/lift-off) vessels which use a crane to load and unload cargo.
RORO vessels have built-in ramps which allow the cargo to be efficiently "rolled on" and "rolled off" the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps, the term RORO is generally reserved for larger ocean-going vessels. The ramps and doors may be stern-only, or bow and stern for quick loading.
Chania (Greek: Περιφερειακή ενότητα Χανίων) is one of the four regional units of Crete; it covers the westernmost quarter of the island. Its capital is the city of Chania. Chania borders only one other regional unit: that of Rethymno to the east. The western part of Crete is bounded to the north by the Cretan Sea, and to the west and south by the Mediterranean Sea. The regional unit also includes the southernmost island of Europe, Gavdos.
