The Cruise Boom: Record Passengers and Ever Bigger Ships Take to the Seas
Global cruise passenger numbers hit a record 37.2 million in 2025, with the industry now forecasting 42 million by 2028. Royal Caribbean's Icon of the Seas leads a fleet of floating resorts, as 13 new ships and an 87 billion dollar orderbook push the boom onward.
The cruise ship, once a fixture of retirement brochures, has become one of the fastest growing corners of global travel. In 2026, the industry is riding a historic wave, carrying record numbers of passengers on ever larger and more lavish vessels.
A record year at sea
The headline figure captures the momentum. Global cruise passenger volume reached a historic high of 37.2 million in 2025, according to the industry body's closely watched 2026 State of the Global Cruise Industry report.
The climb has been steady and steep. That total was up from 34.6 million passengers in 2024 and 31.7 million in 2023, a recovery that has carried the sector well past its levels from before the pandemic.
The optimism runs into the future too. Cruise Lines International Association, which produced the figures, has revised its long-term forecast upward and now projects around 42 million passengers a year by 2028.
Ships the size of small towns
As demand grows, so do the vessels. The clearest symbol of the era is Royal Caribbean's Icon of the Seas, which stands as the world's largest cruise ship with a gross tonnage of around 249,000.
Its dimensions are staggering. The vessel measures roughly 1,198 feet, or 365 metres, in length, making it the longest cruise ship afloat, and it came with a construction cost reported at around 2 billion dollars.
That price tag reflects a new kind of holiday. These floating resorts pack in restaurants, water parks, theatres and whole neighbourhoods, aiming to make the ship itself the destination rather than merely the transport between ports.
A fleet still growing fast
The building has not stopped. In 2026 alone, 13 ocean-going new ships are joining the global fleet, averaging around 94,715 gross tons and 2,085 guests apiece as the big lines race to add fresh capacity.
Some of the newcomers are giants. Among them is Royal Caribbean's Legend of the Seas, the third ship in the Icon class, weighing in at about 250,800 gross tons and carrying roughly 5,600 guests, delivered in June.
The pipeline behind them is enormous. The industry counts some 325 member ships and around 690,000 berths, sitting on top of an order book worth a reported 87 billion dollars for vessels still to come.
Why passengers keep coming back
The growth rests on unusually loyal customers. Nearly 90 per cent of people who have taken a cruise say they intend to sail again, a rate of repeat intent that most other corners of the travel industry can only envy.
New blood is arriving as well. Around 31 per cent of passengers in 2025 were first-time cruisers, a sign that the industry is not merely recycling the same travellers but genuinely broadening its overall appeal.
Smooth sailing, with clouds ahead
For all the buoyant numbers, the boom is not without tension. The very crowds that fill these ships have fuelled a backlash in some busy ports, where residents and officials are pushing back against the flood of day visitors that mega-ships can deliver.
Still, the direction is unmistakable. With record passengers, ever bigger ships and a vast order book, the cruise industry looks set to keep expanding, betting that the appetite for holidays at sea will continue to swell for years to come.
