Wikipedia: "Rickmer Rickmers is a sailing ship (three masted bark) permanently moored as a museum ship in Hamburg, near the Cap San Diego.

Rickmer Clasen Rickmers, (1807–1886) was a Bremerhaven shipbuilder and Willi Rickmer Rickmers, (1873–1965) led a Soviet-German expedition to the Pamirs in 1928.

The Rickmer Rickmers was built in 1896 by the Rickmers shipyard in Bremerhaven, and was first used on the Hong Kong route carrying rice and bamboo. In 1912 she was bought by Carl Christian Krabbenhöft, renamed Max, and transferred to the Hamburg - Chile route.

In World War I the Max was captured by the Government of Portugal, in Horta (Azores) harbour and loaned to the United Kingdom as a war aid. For the remainder of the war the ship sailed under the Union Jack, as the Flores. After World War I she was returned to the Portuguese Government, becoming a Portuguese Navy training ship and was once more renamed, as NRP Sagres (the second of that name). In 1958, she won the Tall Ships' Race.

In the early 1960s the Sagres (II) was retired from school ship service when the Portuguese Navy purchased, from Brazil, the school ship Guanabara (originally launched in Germany in 1937 as the Albert Leo Schlageter and renamed NRP Sagres (III)), and was laid up in a shipyard. She was purchased in 1983 by an organisation named "Windjammer für Hamburg e.V.", renamed for the last time, back to Rickmer Rickmers, and turned into a floating museum ship."
