Thank You Hood!
A small, but long-lived riverine tugboat Kormoran
was built in 1898 at R. Holtz Dampf-Boot & Maschinen-Fabrik
in Hamburg for Königlische Weichsel-Strombauwervaltung (Royal Prussian Wisła Water-engineering Administration) of Danzig (Gdańsk). It was 14,32 meters long, was originally powered by a 60 hp double-expansion steam engine and primarily serviced dredging equipment, between 1902 and 1906 being based at Thorn (Toruń) and then back in Gdanzig. In the inter-war period it was used by Wasserstrassebauamt Elbing (Elbląg) and Wasserstrassebauamt Marienburg (Malbork) until sunk in December 1944. In 1945 it was raised, inspected and declared repairable. As Sławomir
(popular male name) it was refitted at Państwowy Warsztat i Stocznia Pleniewo
(State Workshops and Shipyard at Pleniewo) with 105 hp diesel engine (of unknown type) and in late 1946 assigned to Państwowy Zarząd Wodny (State Waterways Administration) branch in Malbork. In 1951 transferred to Rejon Dróg Wodnych (RDW, Waterways Area administration) in Elbląg ,and then briefly to RDW Toruń and later RDW Gorzów Wielkopolski in 1954. In 1958 Sławomir
was deeply rebuilt and equipped with 135 hp CZNM Škoda 3L160 diesel engine, after which Sławomir
was attached to RDW Szczecin, but still homeported at Gorzów. In 1965 it was donated to Liga Obrony Kraju (National Defence League - mass paramilitary organization) as a training ship, which used it until around 1980 when it was struck off the register. Then it was put ashore as a monument and was becoming increasingly derelict, until in 2011 group of enthusiasts initiated ships reconstruction (I have to admit I'm uncertain at what stage it currently is, but I know that significant shipyard works were so far made).
Unfortunately I couldn't find a good ("drawing-sufficient") pictures of Sławomir
in the post-war, modernized form (it had heavily rebuilt superstructure) except in the on-shore derelict condition.
