RoRo

Extracted from the Wikipedia article Roll-on/roll-off.
RORO vessels typically have a multistorey carpark-like cargo hold layout and use either built-in or dock-based linkspans (ramps) or ferry slips that allow the cargo to be efficiently loaded on and off the vessel when in port. The cargo doors and/or ramps may be located in the stern, bow or portsides, or any combination thereof. While smaller ferries that operate short distances across rivers and other waterbodies often also have built-in ramps, the term RORO is generally reserved for large seagoing vessels owned/chartered by the automotive industry for exportshipping.
