Hello; The first cargo ships specially fitted for the transport of large quantities of cars came into service in the early 1960s. These ships still had their own loading gear and so-called hanging decks inside. They were, for example, chartered by the German Volkswagen AG to transport vehicles to the U.S. and Canada. During the 1970s, the market for exporting and importing cars has increased dramatically and the number and type of ROROs has increased also. In 1970 Japan's K Line built the Toyota Maru No. 10, Japan's first pure car carrier, and in 1973 built the European Highway, the largest pure car carrier (PCC) at that time, which carried 4,200 automobiles. Today's pure car carriers and their close cousins, the pure car/truck carrier (PCTC), are distinctive ships with a box-like superstructure running the entire length and breadth of the hull, fully enclosing the cargo. They typically have a stern ramp and a side ramp for dual loading of thousands of vehicles (such as cars, trucks, heavy machineries, tracked units, Mafi roll trailers, and loose statics), and extensive automatic fire control systems. As a Lorry Driver I believe that I have actually recently seen Celine moored up near the Dartford crossing, whilst I was driving over the QE2 Bridge, England, UK I found the content of this video to be interesting and informative.
