Sail Training Ship Kruzenshtern in the Bosphorus

This is almost certainly the Kruzenshtern (Russian: Барк Крузенштерн) heading south through the Bosphorus, seen from Tarabaya Bay on the European side.

The Kruzenshtern is a four-masted barque tall ship built in 1926 at Bremerhaven, Germany as the Padua. She was surrendered to the USSR in 1946 as war reparations and renamed after the early 19th century Baltic German explorer in Russian service, Adam Johann Krusenstern (1770–1846).

Launched in 1926 the Kruzenshtern as the last of the P-Liners, the Padua was commissioned as a cargo ship, used to ship construction material to Chile, returning with saltpetre around Cape Horn. Later she transported wheat from Australia. In 1933–1934 she took a record-breaking 67 days from Hamburg to Port Lincoln in South Australia.

In 1946 she was surrendered to the USSR and integrated into the Baltic Fleet of the Soviet Navy. She was moored in Kronstadt harbour until 1961 where she underwent major repairs and the installation of her first engines. In 1965 she was transferred to the USSR Ministry of Fisheries in Riga to be used as a schoolship for future fishery officers.

She is now a Russian Navy sail training ship, with home ports in Kaliningrad (formerly Königsberg) and Murmansk. She is the second largest traditional sailing vessel still in operation.

She is painted black with a wide white stripe with black rectangles intended to give the illusion of gunports.
