About Harmony of the Seas
Harmony of the Seas, the third Oasis-class ship, was built by STX France at Saint-Nazaire and became the world's largest passenger ship when she entered service in May 2016. Like her sisters she is laid out in seven neighborhoods, including Central Park and the Boardwalk, and she has two surf simulators, three water slides and the Ultimate Abyss dry slide. A six-week refurbishment at Navantia in Cádiz in April 2026 added The Lime & Coconut bar, new restaurants and new suites. She sails Caribbean and Bahamas cruises year-round from Port Canaveral, Florida.
