The most recent addition to Royal Caribbean's (RCCL) fleet of vessels is the 90,090-gt Serenade of the Seas, which was delivered to the cruise line by Meyer Werft Shipyard in Papenburg, Germany on July 30, 2003. The third member of the Radiance-class fleet, Serenade, along with its sisterships, is a luxury cruise vessel boasting a very slim, yachtlike design with extensive use of glass on the outside, as more than 80 percent of the vessel's cabins are designated as outside cabins. Serenade features advanced technology designed to make the ship efficient, and to ensure it is as quiet and vibration free as possible. To this end, it features an advanced gas turbine propulsion plant, and its 15 decks employ the latest in sound dampening technology.
