Ships don't come with much more historical ballast than the MV Liemba. The steamer still shudders and belches its way across Lake Tanganyika every Wednesday and Friday, a century after it was built as a warship in Germany.
In its time it's been a pawn in the colonial scramble for Africa. It's been scuttled and then raised again from the deep. It may have been the model for the warship sunk by The African Queen, a steam-powered launch in the film of the same name, starring Katharine Hepburn as a prim spinster and Humphrey Bogart as the rough captain.
And now it's a ferry on Africa's longest lake, invariably packed with hundreds of people plus their jumble of bundles and baskets as it churns the water between Kigoma in Tanzania across the lake to Mpulungu in Zambia.
But for how long? Such is the ramshackle, dented state of the vessel that the company which runs it has asked the German government to help with refurbishment. The basis of the appeal is that this is a piece of German history. The steamer that serves the citizens around Lake Tanganyika was once the Kaiser's gunboat.
A spokesman for the Marine Services Company told the BBC: "We have requested that Germany help in its rehabilitation. This is because of financial constraints but we have not had a concrete commitment."
The Liemba started life as the Graf Goetzen in 1913 when she was built as a warship in Papenburg on the River Ems in northern Germany. It is said that the Kaiser himself ordered the construction to further his imperial ambitions.
The Graf Goetzen was then transported in parts, in 500 crates, from Hamburg to Dar es Salaam on the coast of East Africa - and from there over mountains to Lake Tanganyika where Germany, Britain and Belgium were all engaged in colonial jostling.
Britain did not take the presence of the vessel easily. As the Admiralty put it: "It is both the duty and the tradition of the Royal Navy to engage the enemy wherever there is water to float a ship."
So London decided to send two gunboats and by an equally difficult route.
Colonial rivalry and conflict then ensued, and, in the face of a British attack, the Germans abandoned the port of Kigoma, scuttling their ship, the Graf Goetzen, to stop it getting into British hands.
The Goetzen then remained at the bottom of the lake for nearly 10 years until she was raised to the surface. Amazingly, the engines still functioned after minor repairs - possibly because the German engineers who had done the scuttling were the ones who had taken it out from Germany... and they took care to encase the engines in grease so that their baby could one day live and steam again.
It is not clear who raised it, perhaps the Belgians or perhaps the British - but whoever did it, the old German gunboat ended up in the hands of the British.
Clearly, a vessel of the Royal Navy could not be named after Count Gustav Adolf von Goetzen, who was a German explorer and governor of German East Africa. So the ship was renamed as the Liemba - which is how she has stayed ever since.
And so may she stay for much longer if she can be renovated. The request for financial help has fallen between the governments of Lower Saxony, in which the ship was built, and the federal government in Berlin.
The president of Germany has added his voice. The ship, said President Christian Wulff, had a "singular history" and performed an "indispensable service" to the people of East Africa. The government of Tanzania joined the clamour for salvation.
A study has been done by the German authorities but it is thought to have concluded that the costs might well be higher than actually building a new ship. But would a new ship be quite the same as an ancient steamer, dented and bulging with history?
