MS Anemos is a cruiseferry owned and operated by the Greek ferry company Aegean Sea Lines.

[1] The market for transporting passengers, cars and cargo trucks across the Baltic Sea between Finland and Sweden grew steadily during the 1960s and the early 1970s.

Inspired by the success of the Aurella, the newbuildings' design resembled her closely although more cabins and larger public spaces were added.

Due to a seaman's strike in Finland, the Rosella wasn't put into service until May 23 when she started sailing on the Naantali-Kapellskär route.

When delivered, the Rosella was put in service on Viking Line's route between Naantali and Kapellskär together with her sister Turella and SF-Line's Aurella.

However, the Amorella's delivery was delayed by seven months, meaning the Rosella could not be delivered to Stena in time for the summer season 1988, and SF Line had to pay them compensations.

[8] In the new situation the Rosella started making 24 (later 20/22) hour cruises from Stockholm to Mariehamn under the marketing name Dancing Queen during the winter season, but still returned to the Naantali–Mariehamn–Kapellskär route for the summer months.

In 1999 the summer route's eastern terminus was changed to Turku, allowing Viking to give up the terminal at Naantali completely.

[3] Due to high prices the Rosella's new route was extremely unpopular during the first year and the company strongly considered selling the ship.

[4][10] However, when the building project was cancelled due to big delays at the shipyard Rosella became the permanent ship to sail on the route.

Viking Line's MS Rosella is sold to the Greek shipping company Aegean Sealines Maritime Co. for 11 million Euros.
