The Silja Symphony passenger ship was unable to depart Stockholm on Sunday evening due to technical problems, according to ferry firm Tallink Silja.
The company said the vessel's stabilisers, which help to reduce the ship's roll on waves, were not functioning correctly, according to a company press release.
The ferry was scheduled to arrive to Helsinki on Monday morning, and to leave the Värtahamnen port at 4:45pm local time.
However, the departure was delayed for hours, and at around 9pm the ferry operator announced that the journey would be cancelled outright.
About 2,100 passengers were given the option to spend the night aboard the ship.
The firm said that it rebooked a handful of passengers who had international airline reservations on the Silja Galaxy to Turku, in southwest Finland to ensure they caught connecting flights on Monday.
Silja Symphony's route from Helsinki to Stockholm on Monday was also cancelled due to the delay, according to the ferry operator.
The company said it was contacting affected passengers on Monday.
News outlets Iltalehti and Ilta-Sanomat previously reported about the cancellation.
