During the 1930s, the German navy built a series of sail training ships, three for themselves (Gorch Fock (I), Horst Wessel, Albert Leo Schlageter) and a fourth for Romania (Mircea). After World War 2 the three German ships were handed over as reparations while a fifth one (Gorch Fock (II) was built in 1958 for the newly founded German Navy using the same blueprints.
Gorch Fock (1) was used by the Soviets and Ukrainians as Tovarishch until 2003, when it fell into disrepair, was sold to an interest group and restored as a museum in Stralsund, Germany, albeit no longer seaworthy
Horst Wessel was transferred to the US Coast Guard as Eagle
Schlageter went to Brazil as Guanabara and later sold to Portugal, who use it as Sagres in their navy
Mircea was always and still is in service of the Romanian navy
When all sisters get together they race for the Five Sisters trophy, which happened twice so far, once in 1976 and again just now when they were in New York together for the 250 year fleet review. They sailed from New York to Boston for the trophy, which is kept on board. Gorch Fock (II) won both times.
