M/S Isabelle is a passenger and vehicle ferry from Tallink-Silja. Isabelle normally operates the route Stockholm-Riga, along with companion ship M/S Romantika. Isabelle is perhaps the oldest ship in Tallink-Silja's fleet (1989), however it has been extensively renovated since then. Isabelle is large, with space for nearly 2500 passengers over 12 decks.
