MS Astor is a cruise ship owned by the Germany-based Premicon, under charter to the Germany-based Transocean Tours. She was built in 1987 under the name Astor by Howaldtswerke-Deutsche Werft (HDW), Kiel in West Germany for the Mauritius-based Marlan Corporation, although originally ordered by the South African Safmarine as a combined ocean liner/cruise ship for the Southampton-Cape Town service.
In 1988, she was sold to the Soviet Union-based Black Sea Shipping Company and renamed Fedor Dostoevskiy (some sources spell the name Fedor Dostoyevskiy, Russian: Фёдор Достое́вский), but spent her time under charter to various West German cruise lines. In 1995 she reverted to the name Astor. Since 1996 she has been under charter to Transocean Tours.
On 28 November 2008, an attempted pirate attack on the Astor in the Gulf of Oman was prevented by the German frigate Mecklenburg-Vorpommern.
Today she operates for Cruise & Maritime Voyages on voyages in Europe, South Africa and Australia.
