SS Nyanza was built in 1907 by Bow, McLachlan & Co. in Paisley, Scotland, as a "knock-down" vessel – its parts were prefabricated, then shipped to East Africa for reassembly. The sections were reconstructed at the Uganda Railway’s port in Kisumu (on Lake Victoria, in what is now Kenya), and the steamer was launched there in late 1907. Nyanza had a gross tonnage of 812 and was powered by twin 450 hp triple-expansion steam engines driving two screws. It was commissioned by the Uganda Railway to expand lake transport and was primarily used for cargo service (unlike some sister Lake Victoria ferries that carried passengers).
From 1907 onward, SS Nyanza hauled freight across Lake Victoria as part of the colonial railway’s transport network. Ownership passed to the Kenya and Uganda Railways and Harbours in 1929 and later to the East African Railways and Harbours Corporation in 1948, following regional administrative changes. The vessel continued operating through the first half of the 20th century, but with the introduction of newer ships and changes in transportation infrastructure, Nyanza was eventually retired from active service (by the late 1900s) and laid up at Kisumu.
In 2002 a private company (Delship Ltd.) acquired SS Nyanza with plans to convert her into a motor-driven vessel, but the conversion was never carried out. The ship has since remained in a derelict, disused state at Kisumu port. Notably, Nyanza’s original boilers and engines are still intact on board. In 2008, the Nomadic Preservation Society in Northern Ireland considered purchasing these steam engines and boilers for use in the restoration of SS Nomadic (the Titanic’s tender ship), since Nyanza’s machinery was of similar size and vintage. However, that plan fell through due to insufficient funds, and Nyanza’s machinery was left untouched.
Today, SS Nyanza is one of the oldest surviving vessels on Lake Victoria. Though no longer operational, its steel hull and vintage steam engines remain as historical artifacts. The ship sits moored and rusting in Kisumu, a tangible reminder of the early 20th-century steamers that once traversed Africa’s great lakes.
