The “Mainz” was the fastest and most comfortable passenger ship on the river Rhine at the time of its construction at the Christian Ruthof shipyard in Mainz in 1928/29. It was also the last paddle-steamer built on the river Rhine. It can carry 1,790 passengers and is propelled by a 900 HP engine. The Mainz was the only one of the 28 ships in the fleet which survived the Second World War unscathed. All others were either destroyed or sunk. After the war she was once again used as a passenger ship, but was not used very often and served rather as a stand-by vessel. For many years, the ship was moored in Cologne. In 1986, after thorough renovation carried out by the Mann­heim Shipping Association, she finally came to a rest in Mann­heim where she is now exhibited as a museum vessel. The model
size is 1:75.
