”Birka” is a tugboat built in 1898 by “Hernösands Verkstad & Varfs AB”, Sweden. Originally it was propelled by a steam engine with a power of 100 hp. The vessel was delivered to “Stora Kopparbergs Bergslags AB” under the name “Bergslaget”. In 1923 it was sold to Bäck-Daniel Danielsson from Insjön and the name was changed to “Trafik”. In 1953 the boat was modernised with Scania D 818, 180 hp (132 kW) engine. In 1968 the boat was bought by Henry Svensson from Stallarholmen, who changed the name to “Birka”. In 1975 the tug boat was sold to Erik Martin Olsson from Hallstavik. In 1994 the engine was exchanged with a Scania 8 diesel motor, 170 hp (125 kW).
