This ship first began sailing in 2009 and set off the “arms race” of larger ships that continues today. It is powered by six dual-fuel engines, which can be powered by liquefied natural gas (LNG), a fuel alternative that the Cruise Lines International Association says reduces sulfur and greenhouse gas emissions. However, some environmentalists worry LNG-powered ships increase methane emissions. Other say that vacationers generate eight times more carbon on a cruise than they do on land. Royal Caribbean's Quantum of the Seas is the flagship of the Quantum class cruising Asia and the South Pacific half the year, before spending summer in Alaska.
Ovation of the Seas, Royal Caribbean
They've kept getting larger in the past decade, proving that bigger is better. Besides that, we understand you might want to choose the best cruise ship size. Coming in at almost 216,000 gross tons, it’s roughly 14% smaller than Icon of the Seas. From bumper cars to seven pools to an 11-story slide, there’s no shortage of things for kids to do.
Oasis of the Seas (Royal Caribbean)
Costa Smeralda is the cruise line’s first-ever cruise ship powered by Liquified Natural Gas (LNG). She’s also the largest vessel ever constructed for the Italian-based cruise operator. Harmony of the Seas was the first in the class to feature the 10-Story Ultimate Abyss slide, which is located aft of the ship above the AquaTheater. The slide has since been a major feature on new Oasis-class vessels and added during refurbishments.
Royal Caribbean Allure of the Seas
On November 27, 2023, Royal Caribbean’s Icon of the Seas was officially delivered from the Meyer Turku shipyard in Finland to Royal Caribbean. This means that the cruise line takes over responsibility for the giant ship, and the vessel officially becomes a part of the fleet. It now means that Icon of the Seas is the world’s largest cruise ship, overtaking Wonder of the Seas, which is also operated by the same cruise line. Here's a look at the 25 biggest cruise ships currently sailing throughout the world. MSC entered the top ten in 2022 when World Europa made its maiden voyage in December of that year.
Harmony of the Seas, Royal Caribbean
She’s almost identical to the Costa Smeralda, including gross tonnage and size. The only reason she is lower than her sister ship in the largest cruise ships in the world is that she entered service in 2021. As of February 2024[update], there are 68 passenger ships with over 135,000 GT in service. The first ships over that size were the Voyager-class ships from Royal Caribbean Group's Royal Caribbean International (RCI). To help you compare the sizes, we've rounded up and ranked the 30 largest cruise ships in the world by gross tonnage (which is a measure of volume, not weight). We've included other stats, such as passenger capacity (both double occupancy and max occupancy) plus length and beam (the width at the widest point of the vessel).

Top 20 Cruise Ships so Big, You Can Never Miss Them
Kids will love the Altitude zone that features a ropes course, mini-golf, and more. The ship sets sail as Royal Caribbean’s cruises are having a moment online. Since December, the company’s 9-month “Ultimate World Cruise” has captivated — and confused — a following of avid watchers on social media.

Then, when you’re feeling spry and ready for some adventure during your vacation at sea, you can try an escape room or ropes course, play in the sports arena or strut your stuff in a dance class. The Canadian government lifted a cruise ship ban in Canadian waters late last year. Carnival Pinnacle was never built as the project was officially canceled (mainly due to the vessel's incredible cost at that time). However, many of the project's elements and innovative design features were later adapted for other large-sized cruise liners built for rival companies.
However, those ships come in just under the 185,000 gross tons seen with Smeralda and Toscana. Each iteration of Oasis-class ships has arrived just slightly larger than the previous when it comes to gross tonnage. That means they each had their time as the largest in the world before another arrived on the scene. In this case, Symphony of the Seas (228,000 gross tons and the ability to hold 6,680 passengers) took the crown in 2018.
Second Icon-Class Ship Will Have a Furry Family Member

Until Utopia of the Seas launches in 2024, Sun Princess will be among the twenty largest cruise ships afloat on the world’s oceans. The ship’s first cruise is set for February 2024, and will debut Princess Cruises' largest number of dining options, offering guests 29 choices. Royal Caribbean’s Harmony of the Seas, now the fifth-largest cruise ship in the world, was actually the largest cruise ship from 2016 to 2018. Onboard, passengers can find 16 guest decks, 2,747 staterooms and suites and 23 pools and whirlpools.
Unsurprisingly, Royal Caribbean's Icon Class and Oasis Class dominate the top five in both categories. Perhaps more surprisingly, only two other lines join it on the winner's podium. At 250,800 gross registered tons and carrying up to 7,600 passengers (plus 2,350 crew members), it's a true behemoth. The Icon of the Seas is divided into eight neighborhoods across 20 decks. The ship includes six waterslides, seven swimming pools, an ice skating rink, a theater and more than 40 restaurants, bars and lounges. The ship can carry up to 7,600 passengers at maximum capacity, along with 2,350 crew members.
The ship was officially christened Tuesday with help from soccer legend Lionel Messi and his Inter Miami teammates. Harmony of the Seas was the first ship in Royal Caribbean's fleet to feature the Ultimate Abyss dry slide. Since then, it was added to Oasis of the Seas, the namesake ship of the Oasis Class, as well as Symphony and Wonder of the Seas as new builds. The ship is divided into eight separate neighbourhoods, including a cantilevered pool bar named “The Vue” and a giant play area for kids. All of the ships in Royal Caribbean's Oasis Class and Icon Class are at least five times larger than Titanic was.
Royal Caribbean’s leaders say they view liquified natural gas as a “transitional fuel,” and that they hope to continue to reduce the environmental impact of their ships moving forward. The cruise line is positioning the vessel as “the ultimate family vacation,” as CEO Michael Bayley told reporters earlier this year, per CNN’s Maureen O’Hare. MSC World America will also have six pools and 14 hot tubs, making it one of the most pool-covered ships at sea. MSC World Europa is the first ship in MSC Cruises' ground-breaking World Class. Onboard, you'll find the World Galleria, a main thoroughfare that's a hub of activity, as well as an 11-story dry slide located at the aft of the ship.
It features 31 sections, two 360-degree circles, 27-degree slide incline, 28 m (92 ft) serpentine-like drop, 13,14 seconds average sliding time (top to bottom), around 300 small LED lights and graffiti artworks throughout. See here the world's largest cruise ships list (including vessels under construction) owned by the best cruise line companies. This article is also integrated with our ship dimensions, passenger capacity, and old cruise ships surveys. Here's a quick rundown of the world's biggest cruise ships by gross registered tons and maximum passenger capacity.
For more than a century, cruise lines have competed to claim the title of world's largest cruise ship. Carnival Mardi Gras first debuted in 1972 and was a trailblazing ship. Its preliminary focus was on festive fun for all guests (hence the name), which was unlike any other cruise ship at the time. The unique onboard ambiance continues today on the most recent Mardis Gras, which was launched in 2021, and has 17 passenger decks, 2,641 staterooms and a rollercoaster. Arvia is the second Excel class cruise ship for British-based P&O Cruises.
