Lindaliini AS was founded in 1997 as the successor of shipping company Inreko Laeva AS. It started operations with a fleet of three hydrofoils, which were able to make the journey between Tallinn and Helsinki in an hour and a half, much faster than the conventional ferries serving the same route.

Starting in 2007, the hydrofoils were replaced with catamarans, which were less expensive to maintain and had better seaworthiness. Still catamarans are more dependent on the weather than traditional vessels, and Linda Line had a policy of cancelling departures when wind speeds exceeded 15 metres per second and/or wave heights were over 3 metres.^[2]

In 2017, Linda Lines announced the delivery of a new vessel for 2018. Operations ended in November 2017, and Merilin and Karolin were sold off. The announced delivery of the new vessel was initially announced to be delayed. The company eventually filed for bankruptcy in May 2018.^[3]

Sea Flower	Tallinn–Helsinki	Trimaran	–	–	–	Sea Flower	Purchase planned for 2008/9 but not completed.

In 2008, Linda Line planned to purchase a trimaran-type vessel for the Tallinn–Helsinki route, intended to replace hydrofoil Jaanika. The trimaran would have been safer and slightly larger than Merilin. The launch was initially planned for April 2009, but this was soon postponed to June 26, and the purchase was ultimately not completed for unknown reasons. Linda Line started the 2009 season with two catamarans, Merilin and the newly acquired Karolin.

In Tallinn, the Linda Line high-speed ferries departed from Linnahall terminal and in Helsinki from Makasiini terminal. Both ships had a Linda class and a VIP class separated from the rest of the cabin, and the company offered a variety of hotel and leisure packages in Helsinki.^{[citation needed]}

On April 16, 2008, the Tallinn City Government decided to award the contract for the Tallinn-Aegna shipping line to Linda Line. The decision was also helped by a decision made at the end of March to have the route depart from Linnahall terminal instead of Pirita. The line was operated by the small passenger ship Juku. At the beginning of 2010, the right to operate the route with Juku was granted to AS Kihnu Veeteed.^[5]
