The World’s Biggest Cruise Ship is the Royal Caribbean’s ‘Icon of the Seas’, which became operational on January 27, 2024, when she sailed out of Port Miami. It is also the lead ship of the Icon class, with a gross tonnage of 248,663 tonnes.

The ship is 364.75 m long, 48.47 m wide, and 196 feet above the waterline. It has a 9.25 m draft and 20 decks, 18 of which are passenger decks.

The USD 2 billion cruise ship built by Meyer Turku took around 900 days to complete.
It has been designed as a floating resort at sea and has 8 distinct neighbourhoods including:
- Thrill Island: This has the Category 6 waterpark, Crown’s Edge (a skywalk), FlowRider surf simulator, mini golf course, and rock climbing space.

The largest cruise ship has the largest waterpark at sea with 6 waterslides, including the first open free-fall slide named Pressure Drop. There are also 7 pools and 9 whirlpools.
The cruise ship offers 40 dining venues, from casual eateries to fine dining experiences including Empire Supper Club, Pearl Cafe and The Grove.
For entertainment, the guests can enjoy Broadway-style shows in the theatre, acrobatic performances in the Aquadome with live music, comedy clubs and a majestic waterfall.
Icon of the Seas is environmentally sustainable as well. It is powered by LNG, has advanced waste management and is energy efficient, thanks to LED lighting, smart HVAC systems and water conservation systems.
