MS Anemos is a cruiseferry, built in 1980 by Wärtsilä Turku shipyard, Finland for SF Line, one of the owners of the Viking Line consortium. She served as Rosella on Viking Line's Kapellskär–Mariehamn route before being sold to Aegean Speed Lines as Anemos in January 2023. Background New vessels for SF Line 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. During these years, two major carriers on these services emerged: Viking Line and Silja Line. By the time of the mid 1970s, the Ålandian based shipping company SF Line operated three ships as a part of Viking Line. Although not more than ten years old, these ships was already beginning to be too small and held too few passenger cabins to meet the growing demand from passengers. In response to this, as well as the newbuilings recently added to the Silja Line fleet, SF Line decided to order two new and bigger ships. These ships would later be known as the MS Turella and the Rosella. Ordering The lowest bid for building the two new vessels came from Mitsubishi Heavy Industries. In order to save job opportunities in Finland, the Finnish state subsidised the construction of the new ships with 17 million Finnish markka. Thus, the order for the ships eventually went to Wärtsilä and both ships were to be built at their shipyard in Turku, Finland. Design SF Line's latest newbuilding was the Aurella, delivered to the company in 1973. The Aurella was of a new breed of ferries crossing the Baltic, she had two decks of public spaces along with two separate car decks. Inspired by the success of the Aurella, the newbuildings' design resembled her closely although more cabins and larger public spaces were added. Naming SF Line's earlier ships were all named with the suffix -ella with the prefix taken from names of the regions where the ships sailed. Thus the had her name taken from the port of Kapellskär, the 's from Mariehamn and the 's from the Aura River in Turku. In this manner, the first of the newly built ships was named the Turella, the name deriving from the city of Turku. The second ship got her name, Rosella, from the region of Roslagen (the coastal areas north of Stockholm). Building and Delivery The Turella
