It's not just bigger. It's more energy efficient, too.
Royal Caribbean's new Symphony of the Seas, the largest cruise ship ever built, sips 25% less fuel than Oasis of the Seas and Allure of the Seas — two slightly smaller sister vessels built in 2009 and 2010, respectively.
As can be seen in the video above, Royal Caribbean has found several ways to improve the energy efficiency of Symphony as compared to Oasis and Allure, which were built on the same platform.
Among them: The implementation of a new system that releases tiny air bubbles under the hull to make the vessel glide more smoothly through the water.
Designed for vacationers who love big, bustling mega-resorts, the 228,081-ton Symphony is the fourth vessel in Royal Caribbean's groundbreaking Oasis Class series. In addition to Oasis and Allure, the series includes Royal Caribbean's two-year-old Harmony of the Seas, the previous size leader in cruising.

Symphony eclipses Harmony in size by more than 1,000 tons and also has more cabins and carries more passengers at double occupancy.
Symphony will spend its first few months sailing in the Mediterranean out of Barcelona before moving to Miami to operate cruises to the Caribbean.
Royal Caribbean's Oasis Class vessels have made waves in the cruise industry since they began debuting in 2009. All of the Oasis Class ships are in excess of 225,000 tons — more than 30% larger than the next largest cruise vessels.
With the addition of Symphony, Royal Caribbean has 25 ships.
