‘Krusenstern’ was built in 1926 at Geestemunde in Bremerhaven, Germany and was surrendered to the USSR 1946 as war reparation. It is now a Russian Navy sail training ship.

A spectacular capsize during training saw China Team's AC45 catamaran racing boat effectively disabled, with a badly broken sail and damage to one of the hulls.

OBTS can be used for training purposes to individual, department and whole ship while it is in port, under sail or in active service without disturbing its mission.
