Harmony of the Seas
Royal Caribbean’s Harmony of the Seas, launched on 19 June 2015 with delivery in May 2016, is one of the world’s largest cruise ships and a standout member of the Oasis Class, positioned as the third ship in the series after Oasis and Allure of the Seas. With an impressive 226,963 GT, the ship stretches 1,188 feet in length and features 18 total decks, including 16 passenger decks. Harmony typically carries 5,479 guests at double occupancy and up to 6,780 maximum, supported by approximately 2,300 crew.
As part of Royal Caribbean’s Royal Amplified programme, Harmony is scheduled for a major refurbishment in April–May 2026, adding new venues, a refreshed pool deck, and an expanded Casino Royale—set to become the largest in the fleet.
The ship features seven neighbourhoods, a defining Oasis Class hallmark, including Central Park and the Boardwalk. Guests enjoy extensive amenities such as 10+ bars and lounges, 20+ dining venues, and 19 pools, including multiple swimming pools, a kids’ splash zone, and whirlpools. USP attractions include The Perfect Storm waterslides, a nine‑deck zip line, two FlowRider surf simulators, rock‑climbing walls, and innovative entertainment venues.
This combination of scale, engineering, neighbourhood design and high‑energy features makes Harmony of the Seas one of the most iconic ships afloat today.
