35-year-old Cesilie Carlton is a champion US diver who, together with her gymnast friend Sydney Brown, performs death-defying stunts for guests on the Royal Caribbean’s Harmony of the Seas …

In the video below, Carlton can be seen leaping off the 16,5 metre diving board, and somersaulting into the blue pool below. This is all done while the ship is moving!

Thankfully the Harmony of the Seas (the largest cruise ship in the world) also boasts the world’s deepest cruise-ship swimming pool. Carlton’s perfect dive and landing could never have been performed safely on any other cruise ship.

Carlton and her partner also perform a number of other awe-inspiring stunts for guests on the cruise.
