She remained in service under the communist government of the Socialist Federal Republic of Yugoslavia, being renamed Orjen in 1945 and Istranka in 1954.

She was put up for sale in 1998 but lay derelict in a Croatian shipyard until purchased and restored by Italian politician Gianfranco Cozzi.

The yacht Ossero was ordered by Archduke Charles Stephen of Austria, a nephew of Emperor Franz Joseph I.

[12] Ferdinand was assassinated in Sarajevo on 28 June and his body was carried part of the way back to Trieste aboard Dalmat.

[7] After the post-war Dissolution of Austria-Hungary she was transferred to the Kingdom of Serbs, Croats and Slovenes and served as one of two yachts (the other being Lada) in the Royal Yugoslav Navy (the state was renamed Yugoslavia in 1929).

Cozzi planned for the vessel to join his collection at Santo Stefano al Mare, but it was prevented from leaving the country in 2003 by the Croatian government.

[7] The vessel sank at its moorings in Split but was recovered on 28 June 2014, despite recovery being complicated by its weak structure and a covering of mud.

The Croatian Maritime Museum took an interest in the vessel but requests to the Ministry of Culture failed to secure funding and it again sank in December 2019.

The estate offered the ship to the Croatian government for €100,000 but this was not progressed as the museum had struggled to raise the funds to make it seaworthy.
