Quads for Quantum: Royal Caribbean orders fourth ship in the class

Royal Caribbean ordered a fourth Quantum-class vessel from the Meyer Werft shipyard for delivery in 2019. 

The cruise line recently announced that a third Quantum ship, Ovation of the Seas, would debut in China in 2017.

Royal have not yet released the name of the build, but they still have two registered names, Passion of the Seas and Pulse of the Seas, which one do you think?  

The 4,180-passenger ships have a sky-diving simulator, bumper cars and a crane-powered observation gondola. 

Royal Caribbean did not disclose the cost but said that based on current ship orders, its projected capital spending for 2019 would be $1.3 billion.

Royal Caribbean Cruises Ltd. said its projected capacity increase in 2019 would be 6.5% across all of its brands.
