The STS Sedov (Russian: Седов), formerly the Magdalene Vinnen II (1921–1936) and the Kommodore Johnsen (–1948), is a 4-masted steel barque that for almost 80 years was the largest traditional sailing ship in operation. Originally built as a German cargo ship, the Sedov is today a sail training vessel.
The Krusenstern or Kruzenshtern (Russian: Барк «Крузенштерн») is a Russian four masted barque and tall ship that was built in 1926 in Bremerhaven-Wesermünde, Germany, as shipyard number "S408" under the name Padua (named after the eponymous Italian city). She was given to the USSR in 1946 as war reparation and renamed after the early 19th century Baltic German explorer in Russian service, Adam Johann Krusenstern (1770-1846).
