MS Isabelle is a cruiseferry owned and operated by the Estonia-based Tallink. She was built in 1989 by Brodosplit in Split, Croatia, back then Yugoslavia, for SF Line—one of the partners in the Viking Line consortium—as Isabella. The ship is currently serving as refugee housing in Tallinn. Isabelle has three sister ships, one in the Viking Line fleet, Gabriella, one in the Corsica Ferries fleet, Mega Victoria and one operated by DFDS Seaways, Crown Seaways. Concept and construction Isabella was the second of two sister ships ordered by SF Line from Brodosplit in Split, SFR Yugoslavia for Viking Line service (the first sister being Amorella). Order for Isabella was placed on 4 February 1986, her keel was laid on 15 September 1987, and she was launched on 13 August 1988. She has twelve decks. Delivery to SF Line took place on 15 June 1989, and on 20 June 1989 the ship left Yugoslavia for Finland. Service history Prior to entering service Isabella visited Pori, Finland where the ship was displayed to the public on 3 July 1989. She had originally been planned to replace Rosella on the Naantali–Mariehamn–Kapellskär route, but the authorities of Kapellskär failed to modernise the port of the town to accommodate a ship of such large size. As a result, when delivered the ship was placed on a new Naantali–Stockholm route for the northern hemisphere summer season, and 24-hour cruises from Helsinki for the rest of the year. In spring 1992 the ship was rebuilt at Naantali with a new skybar on deck 11, new cabins in place of the former second car deck on deck 5 and her livery was slightly altered by the addition of a red stripe running along the windows of deck 6. After the 1992 summer season SF Line decided to terminate the Naantali–Stockholm service and the Isabella was placed on the Helsinki cruise route all year round. In summer 1993 she made a handful of cruises from Helsinki to Visby. After the 1994 summer season Isabella swapped routes with Cinderella and served Helsinki–Stockholm for the next three years. During the summer of 1996, instead of spending the day in Helsinki she made short 'picnic' cruises to Tallinn. These proved to be unprofitable and were terminated after the single season. In 1997 Viking Line placed Isabellas newly purchased sister Gabriella on the Helsinki–Stockholm route and Isabella joined Amorella on the Turku–Mariehamn–Stockholm route.
