STS Sedov in Vladivostok, Russia

STS Sedov, formerly Magdalene Vinnen II (1921–1936) and Kommodore Johnsen (–1948), is a four-masted steel barque that for almost 80 years was the largest traditional sailing ship in operation. Originally built as a German cargo ship, Sedov is today a sail training vessel, training cadets from the universities of Kaliningrad, Saint Petersburg and Astrakhan. She participates regularly in the big maritime international events as a privileged host and has also been a regular participant in The Tall Ships' Races.

It came under Russian state ownership after the surrender of Germany — on 20 December 1945, the British handed over the ship to the Soviet Union as war reparation. In the Soviet Union, she was converted into a sail training vessel of the Soviet Navy
