What makes it different
When Icon of the Seas arrived in Miami in January 2024 she was not an incremental record — she was a step change. At 248,663 gross tons she came in around six percent larger than Wonder of the Seas, the biggest ship of the previous generation, and with nearly 10,000 people aboard at full capacity she carries the population of a small town. Comparisons to the Titanic became a meme for a reason: Icon is five times the tonnage and about 96 metres longer.
The design is organized as eight neighborhoods rather than decks-with-venues — a resort layout borrowed from the Oasis class and pushed further. The engineering signature is the AquaDome, a 363-tonne glass and steel dome assembled on the ground at Meyer Turku and lifted onto the bow section in one piece, and the LNG dual-fuel plant that made her the largest gas-powered passenger ship ever built at delivery.
Her reign as the world's largest lasted about eighteen months. Star of the Seas matched her in 2025, and Legend of the Seas measured out roughly a foot longer at delivery in June 2026. The title now lives inside her own class — which is exactly how Royal Caribbean planned it.
