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.
