MV Liemba, formerly Graf Goetzen or Graf von Goetzen, is a passenger and cargo ferry that runs along the eastern shore of Lake Tanganyika. The Marine Services Company Limited of Tanzania sails her, with numerous stops to pick up and set down passengers, between the ports of Kigoma, Tanzania and Mpulungu, Zambia. Graf von Goetzen was built in 1913 in Germany, and was one of three vessels the German Empire used to control Lake Tanganyika during the early part of the First World War. Her captain had her scuttled on 26 July 1916 in Katabe Bay during the German retreat from Kigoma. In 1924, a British Royal Navy salvage team raised her and in 1927 she returned to service as Liemba. Liemba is the last vessel of the German Imperial Navy still actively sailing anywhere in the world. Liemba is believed to be the inspiration for the German gunboat Luisa in C. S. Forester's 1935 novel The African Queen, and John Huston's subsequent film version. The ship featured in the 1992 BBC Television travel series Pole to Pole. Indican Pictures and Breadbox Productions released a documentary on the ship in 2010, Liemba. History Early history The Meyer-Werft Shipyard in Papenburg, Germany, built Goetzen in 1913 and named her after Count Gustav Adolf Graf von Götzen, the former governor of German East Africa. Goetzen was designed to serve as a passenger and cargo ferry in conjunction with the Ostafrikanische Eisenbahngesellschaft (East African Railway Company). After preliminary assembly Goetzen was taken apart and shipped in 5000 boxes loaded on three cargo vessels to Dar es Salaam in German East Africa (modern day Burundi, Rwanda and Tanganyika (the mainland part of present Tanzania)). From there the trains of the Mittellandbahn ("Central Line") carried the boxes to Kigoma. She was rebuilt there in 1914 and launched on 5 February 1915. Originally the ship had seven first class cabins (single bed & sofa bed) and five second class cabins (double bed), as well as first and second class dining and smoking rooms. The machinery consisted at first of two round boilers for steam for the two triple expansion engines with a power rating of per engine. She also had a carbonic ice and cooling unit in an insulated cold storage with a capacity of of ice per hour, and a lighting and a ventilation system. The ship was designed for a crew of 64 men
