”M/S Silja Serenade” is a cruise ship and Ro-Pax ferry, built in 1990 at Turku New Shipyard, Finland by Masa-Yards. It is one of two sister-ships, with the other called “”M/S Silja Symphony”.The construction of “Silja Serenade” took about three years from the initial order on 26th of October 1987 until delivery to the first owner, “EffJohn”, on 15th of November 1990. The cruise-ferry officially began operations on the route Helsinki–Stockholm on 18th of November same year, with home-port of Helsinki. In 1992 the home-port was changed to Mariehamn, Åland. The owner was formally changed to “Silja Line”, where “EffJohn” is a founding member and from 1993 “Silja Serenade” was assigned to the Turku–Mariehamn–Stockholm route. In 1995, the cruise-ferry was returned to the original Helsinki-Stockholm route and from 1999 a stop at Mariehamn was introduced to shape her final route as Helsinki–Mariehamn–Stockholm. In 2006, the owner company was sold to “Tallink”, Estonia and consecutively the ownership of “Silja Serenade” was changed. The same year the interior and part of the exterior were rebuilt at Turku shipyard to reflect the concept of “Tallink”. In 2010 the ship was submitted to another major reconstruction of the interior and yet another one in 2014, both performed at Turku shipyard, Naantali. There were some disruptions of the routine schedule during the COVID-19 pandemic, redirecting the cruising of “Silja Serenade” to Helsinki–Riga route. However, since 2021, the ship is operating on its usual destination along the Helsinki–Mariehamn–Stockholm route.
