on 10 March when she accidentally rammed the quay in Turku in dense fog, suffering serious damage to her bow, and the second time on 14 December when she collided with the Polish freighter Rusalka in the Turku archipelago. This time damages were minimal. After the partner companies of Silja Line took delivery of three new large ferries for Helsinki–Stockholm and Turku–Stockholm routes in 1975, Fennia spent portions of the following years either laid up or chartered to other companies. Between January and April 1975 she was docked in Helsingör, where her engines were changed to more powerful MaK diesels. Between July and October of the same year the ship sailed on the Turku–Åland–Norrtälje (Sweden) route. In June 1976, Fennia became the first ship to visit Valmet's new shipyard in Kotka. In October 1977 she was laid up in Turku until the Swedish Sessan Linjen company chartered her for traffic from Gothenburg (Sweden) to Travemünde (Germany) and Frederikshavn (Denmark) between January and March 1978. After the charter she was briefly laid up again, until in late April she returned to Turku–Stockholm traffic. She was again chartered off for the duration of January 1979, when she sailed between Malmö (Sweden) and Travemünde for SAGA Linjen. After the charter, Fennia stayed on the Turku–Stockholm traffic until November 1982, when she was laid up and put up for sale. No buyer was immediately forthcoming, and for the summer season 1983 she was chartered to the Irish B&I Line for traffic between Pembroke–Cork. Fennia was found to be ill-suited for this traffic as she had no stabilisers. Finally in November 1983 Fennia was sold, to the Finnish Jakob Lines for delivery in 1984. Before her sale, Fennia served for Silja Line one more time, this time on the Helsinki–Stockholm route in January and February 1984 when the route's normal ships were being docked. 1984–2000 In May 1984, Fennia began service with Jakob Lines. Initially she was set on the new Jakobstad (Finland) – Örnsköldsvik (Sweden) route, later also on Jakob Lines' traditional Jakobstad–Skellefteå route. On 28 November two passengers were injured during a heavy storm. Fennia was from the beginning too large a ship for Jakob Lines and already in December 1985 she was sold to Vaasanlaivat / Vasabåtarna (in exchange for Fenno Express and 19.1 million Finnish marks). Between January and April 1986 Fennia was heavily rebuilt at Wärtsilä Turku shipyard. Her terraced
