Harmony of the Seas may be the king of the ocean. The biggest ship in the world is the new addition in the Royal Caribbean fleet. Everything about this vessel is done in grand proportions. At 362-meter long, this structure is larger than the Eiffel Tower in France. It cost a mere $1 billion to build this floating city. It took 32 months to complete the 16 deck ship which boasts the tallest slide at sea, and the deepest pool at sea. Harmony of the Seas set sail this week for the first time from Southampton, England.
