Project Leonardo revealed by Norwegian 

Norwegian Cruise Line has released new images for its recently announced new class of ship, to be built at Fincantieri, Italy.  
The first of four ships, dubbed Project Leonardo, will debut in 2022. At 140,000-tons, they will be smaller than the current Breakaway Plus Class of ship that are currently being constructed in Germany. The design is certainly an evolution of this current class, with an expanded open promenade to feature restaurants and other venues. The design also reflects implementation of technological and environmental efficiencies.
