rear superstructure was built in with cabins, the midship dummy funnel / observation lounge was removed, the two actual funnels to the rear were given a sleeker appearance and to support the additions rear sponsons were added. On 25 March 1986, Fennia began her service for Vaasanlaivat / Vasabåtarna on the Vaasa (Finland) – Sundsvall (Sweden) route. During her service with Vaasanlaivat She also served on the Vaasa–Umeå, Jakobstad–Umeå and Jakobstad–Skellefteå routes (the latter two after Vaasanlaivat bought Jakob Lines in 1989). In the beginning of the year 1990 Vaasanlaivat changed its name to Wasa Line. On 12 November 1991 an accident in the engine room resulted in 14 tons of fuel oil leaking into the sea outside Örnsköldsvik. Between April and October 1992, Fennia served on the routes Vaasa–Umeå, Jakobstad–Umeå, Jakobstad–Skellefteå and Kokkola–Skellefteå. In October 1992, she was chartered to Baltic Line for traffic from Norrköping (Sweden) to Riga (Latvia). In the beginning of 1993 Wasa Line was merged into Silja Line. Fennias charter to Baltic Line ended in March 1993 and in May of the same year she returned to her previous routes across the Kvarken, now back in Silja Line colours. In 1994 the line from Kokkola was terminated. For the winter season 1994–1995, Fennia was chartered to Silja Line's subsidiary SeaWind Line for traffic on her old route Turku–Stockholm. After the end of the charter in May 1995, Fennia again returned to traffic across the Kvarken, sailing Vaasa–Umeå during the winter season and a varied itinerary from Vaasa and Jakobstad during the summer. In 1997 the Kokkola–Skellefteå route was reopened, although traffic was limited to weekends during the summer season. In 1998 the traffic from Kokkola was again discontinued (this time for good), but Fennia continued to traffic on the Vaasa–Umeå, Jakobstad–Umeå and Jakobstad–Skellefteå routes. A special Jakobstand–Luleå cruise was also made during the summer. In May and June 1999 Fennia trafficked from Jakobstad for the last time, the end of tax-free sales in intra-EU traffic in July 1999 meant that the traffic from Jakobstad was no longer profitable. The end of Tax-Free sales also affected the Vaasa–Umeå route badly, and on 23 September 1999 Fennia was laid up and put for sale. Pending a potential charter to a Turkish company, Fennia was docked in May 2000 and all Silja Line markings were painted over. The charter didn't materialise, but she was chartered to SeaWind Line
