Her service speed was planned at 16.50 kn (30.56 km/h), and she was to carry 1000 passengers, 332 of them in two classes with berths and the rest as classless deck passengers. For the first time in Finland SS Co's history, the new ship was fitted with diesel engines and included side-loadable car deck for 50 cars. In the early 1960s the Finland Steamship Company decided to construct a 5,171 gross register ton ship for the Finland-Sweden service the company operated in collaboration with Steamship Company Bore, Rederi AB Svea, and Siljavarustamo, a joint subsidiary of the three companies. On 28 November 1968 the Ilmatar collided with the Siljavarustamo ferry Botnia in the Åland archipelago, resulting in the death of six people on board the Botnia. After several further changes of ownership, the ship was sold for scrap in 2011. In 1997 she received the name Palm Beach Princess. In 1984 she was sold to Grundstad Maritime Overseas and renamed Viking Princess for cruising with Crown Cruise Line. In 1980 the Ilmatar was sold to Vesteraalens Dampskibsselskab, without a change of name. In 1979 she was converted to a cruise ship. Between 1975–1976 she was chartered to Finnlines.

In 1973 she was lengthened at HDW Hamburg, Germany by 20.04 m (65 ft 9 in). From 1970 until 1974 and again from 1978 to 1980 she was marketed as a part of Silja Line fleet. She was built in 1964 by Wärtsilä Hietalahti shipyard, Helsinki, Finland for Finland Steamship Company as Ilmatar.
