SERENE

Built for a Russian owner under an extreme blanket of secrecy, Serene, the first yacht from Fincantieri, the large Italian commercial shipyard in Muggiano, Italy, was launched in September 2010 with completion, blue hull paint and sea trials in 2011. She is the largest yacht ever launched in Italy and features more than 4,000 square meters of interior space among seven decks, plus two helipads and a hangar. She reportedly carries a 100-metre submersible. Standout features include a sauna and adjacent snow room for a true Nordic experience.
