Built by Fincantieri Yachts and designed by Monaco's Espen Oeino designers, the Serene launched in 2010. Construction began in 2007, and when it was completed, it was the largest yacht ever built in Italy.
The Serene features seven decks, two helicopter landing platforms, storage for a large submarine and a large internal seawater pool.
