“Pure car carriers“ is a scientific paper that describes transport ships, the methods used in the manipulation of cargo and its securing and the equipment used to access the ship. The paper describes the development of ro-ro ships, from which specialized ro-ro ships of various types were created. A new way of transshipping cargo has changed the market. The wheeled cargo handling system was rapidly developed and a major advantage was the shorter stay in ports due to interruptions. The vehicle transport market has spread all over the world and the transport of such cargo is the most profitable by ship due to lower costs and the large capacity of ship's holds. Over the years, the capacity has been better utilized by improved cargo stacking methods as well as structural changes in ship's warehouses. Various accidents led to the need to improve the safety of ships for the transport of vehicles, and special rules were issued regarding the stacking and securing of cargo. Different materials and methods are used in order to prevent the cargo from moving during navigation, thus jeopardizing the stability of the ship.
