Royal Caribbean is upgrading Navigator of the Seas and when it is finished, it will include the world's longest water slide at sea, which includes a section that extends over the side of the ship.
The Blaster water slide is over 800 feet in length and will propel a two-person raft over hills and drops.
In addition, Royal Caribbean is adding another slide to Navigator called, Riptide, Riptide, which will plunge riders headfirst down the cruise industry's very first mat racer slide, finishing with an exhilarating home stretch through a translucent tube offering breath-taking ocean views.
Navigator of the Seas is undergoing a $155 million upgrade and will relaunch on February 24 in Miami.
