A look inside the Icon of the Seas, the world's biggest cruise ship, as it prepares for voyage

Royal Caribbean is redefining the cruise industry with its latest ship, the Icon of the Seas. This $2 billion floating resort is largely booked until 2026.

Spanning nearly 1,200 feet, the cruise ship has 20 decks, which makes the Icon of the Seas the world's largest cruise ship.

It's a city at sea, accommodating up to 7,600 passengers in 2,805 staterooms and nearly 10,000 people, including the crew. The ship offers different experiences that include seven pools — one is the largest on any ship — the world's first onboard water park with six water slides, theaters, a casino and over 40 dining and drinking spots.

Jay Schneider, Royal Caribbean's Chief Product Innovation Officer, says the cruise ship is more than just its amenities.

"It's really about iconic experiences," he said.

And despite its massive size, Schneider said the ship is designed to avoid feeling overcrowded.

"We have purposely designed the ship to give more space for people," he said. "We believe, even at 7,500 guests, it won't feel to you like your entire hometown has joined the ship," said Schneider.    

Luxury comes at a price on the Icon. A weeklong Caribbean cruise costs about $3,500 for two people in an average stateroom. For those seeking more luxury, the Ultimate Family Townhouse – a three-story suite complete with touchscreen tables and a slide – can go for up to $100,000 per trip. The Royal Loft, aimed at high-rolling adults, offers two bedrooms, a private hot tub, and a spacious balcony starting at $40,000.

Colleen McDaniel, editor-in-chief at Cruise Critic, said that bigger ships benefit both passengers and cruise lines.

"It means more people can experience something. It means that there's a lot more amenities and activities onboard the cruise ship," McDaniel said. "The more people they can put on a cruise ship, of course, the better business they do, the more money they make."

Kevin Curran says the Icon took his breath away. Having followed the ship's construction for over a year, the Oregon resident said he's thrilled to be on its inaugural cruise from Miami.

"The more I watched the videos, the more I understood this was something special," he said.

Cruising is surging in popularity. Last year, passenger volume outpaced pre-pandemic numbers, and this year is expected to hit a new high of 36 million as spending on experiences has climbed 65% since 2019.

From the bridge, Captain Hendrik Loy is overseeing what amounts to a three-day test drive to the Bahamas.

"There is still fine-tuning that needs to take place," said Loy.

The Icon also champions environmental responsibility. It's powered by liquefied natural gas, treats its own waste, and produces its own water.

MIAMI (AP) — The world's largest cruise ship — the size of almost four city blocks — is set to begin its maiden voyage Saturday as it leaves from the Port of Miami.

Royal Caribbean's Icon of the Seas runs nearly 1,200 feet (365 meters) from bow to stern.

The ship, which is leaving South Florida for its first seven-day island-hopping voyage through the tropics, was officially christened Tuesday with help from soccer legend Lionel Messi and his Inter Miami teammates.

“Icon of the Seas is the culmination of more than 50 years of dreaming, innovating and living our mission – to deliver the world’s best vacation experiences responsibly," Royal Caribbean Group President and CEO Jason Liberty said earlier this week. “She is the ultimate multigenerational family vacation, forever changing the status quo in family travel and fulfilling vacation dreams for all ages on board.”

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.

Millions are following the journey through the eyes of the passengers, as they live and post their lives aboard a vessel they’ll be on for nearly a year. If it sounds like a reality show, that’s exactly what some watchers have turned it into.

When the Icon of the Seas was first revealed in October 2022, the ship spurred the single largest booking day and the highest volume booking week in Royal Caribbean’s then 53-year history, according to the cruise line.

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.

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 says every kilowatt used on the Icon of the Seas “is scrutinized for energy efficiencies and emission reductions.”

Royal Caribbean cruise ships ranked by size from biggest to smallest — the complete list

Are you looking for the most activity-packed, megaresort-like Royal Caribbean cruise ships at sea? If so, you'll want to get on one of the biggest Royal Caribbean cruise ships.

The biggest Royal Caribbean cruise ships are, by nature, the Royal Caribbean ships with the most pools, waterslides and other deck-top activities, as well as the most onboard restaurants, bars and showrooms. They have the biggest casinos and spas among ships in the Royal Caribbean fleet as well as the most cabins and suites — and the most variation in cabin and suite types.

With room for 6,000 passengers or more, the biggest Royal Caribbean ships are truly massive resorts like you find at such landlocked destinations as Orlando and Las Vegas. If you're in the "bigger is better" camp when it comes to a resort experience, these are the Royal Caribbean ships for you.

Still, Royal Caribbean doesn't just operate massive vessels. The Miami-based cruise giant also operates quite a few relatively small cruise ships that carry just 2,000 or 3,000 people and have a much more intimate feel. In some cases, these vessels are just half or a third of the size of Royal Caribbean's biggest ships. These ships, notably, have far fewer deck-top activities and interior venues than the biggest Royal Caribbean cruise ships.

The smallest Royal Caribbean cruise ships are best for vacationers who like a more intimate, less crowded resort experience.

What is the biggest Royal Caribbean ship?

The biggest Royal Caribbean cruise ship is the just-unveiled Icon of the Seas . Measuring 248,663 gross tons, it's not only the biggest Royal Caribbean ship but also the biggest cruise ship ever built by any line. It's loaded with more bars, restaurants, theaters and deck-top attractions than you'll find on any other ship at sea.

Icon of the Seas is the first in a new series of ships at Royal Caribbean that are bigger than anything seen before. The series is called the Icon Class. A second ship in the Icon Class, Star of the Seas , is due to debut in 2025.

How big is Icon of the Seas?

At 248,663 gross tons, Icon of the Seas is more than 6% larger than Royal Caribbean's 1-year-old Wonder of the Seas , which previously was the biggest ship in the Royal Caribbean fleet (and the biggest ship operated by any line). Icon of the Seas can carry up to 7,600 passengers — a new record for a passenger ship. That's about 7% higher than the maximum capacity of Wonder of the Seas, which can hold up to 7,084 passengers.

The bigger passenger capacity is partly due to the ship's greater focus on family travelers. Icon of the Seas was built with a lot more cabins that have plenty of extra bunks to accommodate families with many children. It also has more amenities geared toward families. This includes a new-for-the-line outdoor "neighborhood" called Surfside dedicated to families with young children.

What is the smallest Royal Caribbean ship?

The smallest Royal Caribbean cruise ship is Grandeur of the Seas. Measuring just 73,817 tons, it's just a third the size of Icon of the Seas.

Grandeur of the Seas dates to 1996, a time when cruise ships were built far smaller than they are today and with far fewer venues. At 28 years old, it's the oldest vessel in the Royal Caribbean fleet and probably will be phased out sometime in the next few years.

Except for a rock climbing wall, Grandeur of the Seas has none of the gee-whiz Royal Caribbean top-deck attractions found on newer Royal Caribbean vessels, such as skydiving simulators and giant water parks. For the most part, its top deck is lined with pools, whirlpools and sunning areas, as is typical for ships built in the 1990s.

That said, Grandeur of the Seas has a loyal following among Royal Caribbean fans who prefer smaller and more intimate ships.

Royal Caribbean has hinted of late that it might build a new series of smaller ships that could replace Grandeur of the Seas and other older small vessels in the line's fleet.

Are bigger Royal Caribbean ships coming?

Royal Caribbean currently has three new cruise ships on order, all of which will be among its biggest cruise ships ever — if not the biggest.

The ships on order include two more vessels in the line's Icon Class series that will be similar to Icon of the Seas. They're on order from a shipyard for delivery in 2025 and 2026, respectively. Both ships are expected to be as big or bigger than Icon of the Seas.

Related: The ultimate guide to Icon of the Seas itineraries, attractions and more

Royal Caribbean also has one more ship in its popular Oasis Class series on order for delivery in 2028.

Launched in 2009 with the debut of Oasis of the Seas, the Oasis-class ships have dominated the world of mega-size cruise ships since that year. At the time the class began rolling out, the vessels were around 40% bigger than the next-biggest cruise ships, and they have continued to be among the biggest and most amenity-laden ships in the world ever since.

The new Oasis Class vessel, which is as-yet unnamed, is expected to be roughly the same size as Utopia of the Seas, Royal Caribbean's second-biggest cruise ship. But it'll be smaller than the line's biggest ship, Icon of the Seas.

What's the difference between bigger and smaller Royal Caribbean ships?

Royal Caribbean's biggest ships have room for many more onboard venues and attractions than Royal Caribbean's older ships. That makes them more alluring for vacationers who prefer a big, bustling megaresort experience to a stay at a smaller resort.

On Royal Caribbean's biggest Oasis-class vessels, for instance, you'll find three separate main pool areas, a kiddie splash zone, surfing simulators, a miniature golf course, a basketball court and even a zip line. And that's just on their top decks. Inside the vessels, you'll find more lounges, bars, restaurants and shops than you can imagine — plus huge casinos, spas and showrooms with Broadway-style shows. They even have indoor ice skating rinks.

The line's new Icon of the Seas has a similar array of amenities.

Related: The ultimate guide to Royal Caribbean

Royal Caribbean's smallest ships are a half to a third smaller than the Oasis Class and Icon Class vessels and lack many of the above features. They have a much more intimate feel, at least in the pantheon of relatively big, mass-market ships, and they hold far fewer people. While Oasis Class and Icon Class ships can hold more than 5,400 passengers at double occupancy, the line's four oldest vessels (known as the Vision class) are only designed to carry about 2,000 passengers at double occupancy.

Royal Caribbean's smallest ships are a good choice for someone who wants to try Royal Caribbean but isn't eager to travel with huge crowds. The smallest ships in the Royal Caribbean fleet thus appeal to a subset of Royal Caribbean fans who prefer more intimacy in a cruise vessel and don't mind giving up some onboard amenities to get it. They are also often less expensive on a per-day basis for cruisers.

Additionally, because of their size, the smallest Royal Caribbean ships can operate itineraries to places that aren't as easy for big ships to visit. Not all ports in the world can handle a ship the size of Icon of the Seas.

Full List: The 10 Current Largest Cruise Ships on the Planet

If you think cruise ships have gotten bigger, it’s not just your imagination. Whereas a ship built in the 1990s might hold 2,500 passengers and come in at around 75,000 gross tons (a measure of ship size), that’s nowhere near the ships built today.

Today, any new ship from a major line will be at least 140,000 gross tons, with many much larger than that. Passenger counts have also swelled, with many new ships carrying 5,000 cruisers when completely full.

But the largest cruise ships on the planet are in another league altogether. They can measure up to 250,000 gross tons (roughly triple the size of a ship built 30 years ago!) and when at full capacity with crew, have nearly 10,000 people onboard.

Why Are Cruise Ships So Big?

Truth be told, while the size of massive modern ships is staggering, not everyone likes the large ship experience. Some people can find them too crowded and too hard to navigate. But not everyone feels that way, and cruise lines have invested literally billions into building ships that are as large as possible. So what is the appeal of a mega ship?

Amenities/Activities: For passengers, the big advantage of size comes with everything that can be fit onto the ship. Instead of the old days where there was a pool, some loungers, and a buffet, modern mega ships are literal resorts at sea.

There are multiple pools, more than a dozen restaurants, casinos, ziplines, literal parks, ice-skating rinks, rock-climbing walls, spas, and more bars than you can count on your fingers and toes.

All of that combines into an experience that can exceed expectations and keep passengers coming back for more.

Efficiencies of Scale: For cruise lines, one big positive about a larger ship are greater efficiencies. Instead of having the cost of building two smaller ships — and the costs of having two sets of crew to run them both — one larger ship offers the chance for just as many passengers at a lower cost.

Marketing: Finally, one overlooked aspect of why cruise ships are bigger than ever has to do with marketing and publicity. There’s a certain awe and interest that comes with the world’s largest ships. Seeing them in port is essentially a giant billboard for a cruise line. And the largest ships also get significant press due to their size. All of that can translate into more interest, ticket sales, and prices for the newest — and biggest — ships.

With that in mind, here is the current list of the world’s largest cruise ships as of now…

Icon of the Seas

When it comes to the largest ships, Royal Caribbean is the undisputed leader with the six biggest cruise ships in the world. But the king of the fleet — and the largest cruise ship in the world — is Icon of the Seas .

Icon of the Seas doesn’t sail with passengers until 2024, but it’s already made waves. It’s not just the massive size (250,800 gross tons and 7,600 passengers at maximum capacity), but what’s onboard. A full-fledged waterpark, seven different pools, and eight different neighborhoods offer a spot for everyone. This ship looks to change cruising forever.

• Gross Tonnage: 250,800
• Length: 1,198 feet
• Passenger Capacity: 5,610 double occupancy; 7,600 max capacity
• Year Built: 2023

Wonder of the Seas

Wonder of the Seas is the latest edition of Royal Caribbean’s Oasis-class ships (until Utopia of the Seas arrives in 2024), which were the largest class in the world until the new Icon class took the torch. Still, it’s not as if Wonder of the Seas is a slouch.

At 235,600 gross tons, there’s room for 7,084 passengers and an amazing amount to see and do onboard. This includes Central Park, the mid-ship outdoor promenade that winds through lush gardens, and the AquaTheater, where performers put on aquatic shows, including towering high dives at sea.

• Gross Tonnage: 235,600
• Length: 1,188 feet
• Passenger Capacity: 5,734 double occupancy; 7,084 max capacity
• Year Built: 2022

Symphony of the Seas

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.

Today, it’s the third-largest cruise ship on the planet, but it’s no slouch. It holds seven different neighborhoods, nearly 3,000 staterooms, three waterslides, and Ultimate Abyss — a 10-story dry slide.

• Gross Tonnage: 228,081
• Passenger Capacity: 5,518 double occupancy; 6,680 max capacity
• Year Built: 2018

Harmony of the Seas

Built in 2016, Harmony of the Seas features 18 decks, more than 225,000 gross tons (about 10% smaller than Icon of the Seas) and can carry nearly 6,700 passengers when completely full. That’s good enough to make it the fourth-largest cruise ship in the world.

It features many of the same components of other ships in the class, like the adults-only Solarium, Central Park, and the AquaTheater. That’s not to mention 17 different spots to grab a bite to eat.

• Gross Tonnage: 226,963
• Passenger Capacity: 5,479 double occupancy; 6,687 max capacity
• Year Built: 2016

Oasis of the Seas

The ship that started the trend of truly mega ships is also the namesake of the Oasis class — Oasis of the Seas. If you notice, most of the largest ships on our list were built recently. This ship first began sailing in 2009 and set off the “arms race” of larger ships that continues today.

Following a refurbishment, it now features three waterslides, a dozen lounges, 2,801 cabins (including one with a panoramic view right above the ship’s bridge), a splash pad for kids, and even an escape room themed like the 1960s NASA mission control. And did we mention 20 different places to find something to eat?

• Gross Tonnage: 226,838
• Length: 1,187 feet
• Passenger Capacity: 5,602 double occupancy; 6,771 max capacity
• Year Built: 2009

Allure of the Seas

Following a refurbishment of Oasis of the Seas, Allure of the Seas — which was the second ship in the class and built in 2010 — is actually now the smallest of the group based on tonnage. Still, that’s good enough for sixth largest in the world at “just” 225,000 gross tons.

On the ship, you’ll find 18 decks, 2,748 staterooms and more than 6,800 passengers when completely full. That’s definitely a lot of people, but remember that you also have a lot more space to spread out, giving plenty of elbow room.

• Gross Tonnage: 225,282
• Passenger Capacity: 5,496 double occupancy; 6,826 max capacity
• Year Built: 2010

MSC World Europa

While Royal Caribbean has a lock on the largest ships, the title of largest cruise ship from outside that cruise line goes to MSC World Europa.

Coming in at almost 216,000 gross tons, it’s roughly 14% smaller than Icon of the Seas. But don’t think it’s some slouch. From bumper cars to seven pools to an 11-story slide, there’s no shortage of things for kids to do. Adults will love the 13 different dining options and an indoor promenade or Panorama Lounge for shopping, having a drink, or just relaxing.

This ship will be joined in 2025 by sister-ship MSC World America, set to sail stateside.

• Gross Tonnage: 215,863
• Length: 1,094 feet
• Passenger Capacity: 5,231 double occupancy; 6,762 max capacity

Costa Smeralda/Costa Toscana (Tie)

These two ships come in at a tie for the eighth-largest cruise ship in the world. Built in 2019 and 2021, respectively, they both belong to Costa Cruises. And if the shape of the ship looks familiar, that’s because Costa is a sister line to Carnival. A similar design is used for Carnival’s largest ships, Mardi Gras, Celebration, and Jubilee. However, those ships come in just under the 185,000 gross tons seen with Smeralda and Toscana.

Both ships offer 13 pools and hot tubs, nearly a dozen restaurants and just under 20 bars and lounges. And if you like balcony views? There are 1,550 balcony rooms on each, providing plenty of options for the roughly 6,500 passengers that can sail at full capacity.

• Gross Tonnage: 185,010
• Length: 1,106 feet
• Passenger Capacity: 5,224 double occupancy; 6,554 max capacity
• Year Built: 2019/2021

P&O Arvia

Taking the crown as the 10th-largest cruise ship in the world is Arvia from P&O Cruises. Measuring just under 185,000 gross tons, it offer a similar design to ships like Costa Smeralda and Carnival Celebration, but don’t think these ships are all the same.

For instance, Arvia features a unique Skydome area that is a pool area with retractable roof by day and an entertainment venue by night. It also features its own rum distillery onboard, meaning you can take home rum literally made on the ship. Kids will love the Altitude zone that features a ropes course, mini-golf, and more. There’s also Mission Control, a submarine-themed escape room.

All told, a reported 6,685 passengers can enjoy the ship at one time.

• Gross Tonnage: 184,700
• Length: 1,130 feet
• Passenger Capacity: 5,200 double occupancy; 6,685 max capacity

People have one question as world's largest cruise ship makes its grand entrance

Royal caribbean's icon of the seas cruise ship boasts a whopping 20 decks and weighs 248,663 gt.

Brenna Cooper

People have been left with the same question on their minds after seeing footage of mega cruise ship Icon of the Seas arriving at a US harbour.

The Icon of the Seas - also known as the world's biggest cruise ship - has been making headlines since it set sail earlier this year as people simply cannot get over its size.

The Royal Caribbean International ship first set sail on 27 January and constantly amazes people by the fact it's so bl**dy massive.

Measuring 364.75 m (1,196.7 ft) long and 66 m (217 ft) at its biggest points, the Icon is often referred to as a sailing city, thanks to the fact that it has a water park, a mini shopping mall and even an ice arena.

The ship was recently filmed arriving at the Port of Miami, showing off its phenomenal size for all to see. The clip has since circulated across social media , with the majority of viewers absolutely baffled as to how a ship of this size is able to remain afloat in the ocean.

"How tf does this float," one person wrote on X, while a second person added: "World's largest Cruise Ship. Icon of the Seas, somebody tell me how does this thing manage to float."

"You could explain it to me in a billion different ways... I still don't understand how this thing can float," a third person commented.

Of course cruise ships are specifically designed not to tip over, but it's still difficult to see a picture of Icon of the Seas and not worry that a large wave or strong gust of wind would flip the boat sideways.

Thankfully the beauty of the internet means there is always an engineering expert readily available to spell things out in layman's terms.

Replying to a tweet asking someone to explain to them 'like a five-year-old' how the ship manages to stay upright and afloat, an engineering student replied : "The water is pushing up on the ship with a force equal to the weight of water it pushes aside. Because the ship is so big, it pushes aside a lot of water, creating a strong upward force."

Explaining why the bottom of the ship doesn't need to be majorly submerged in water, they continued: "The ship only needs to sink a little bit into the water to float. You can see the waterline - everything below that is pushing water out of the way, creating the upward force that keeps it afloat.

"While parts of the ship (like the hull) are very dense, the overall density of the entire vessel is less than water due to its largely hollow design. This lower average density is what allows such a giant structure to float effortlessly on water."

So there you have it, the Icon of the Seas is perfectly safe to travel the world's oceans - no matter how ginormous it looks.

Icon of the Seas: Everything you need to know about the largest cruise ship in the world

The world's largest cruise ship, complete with 20 decks and six waterslides, is getting ready to set sail for the first time.

Royal Caribbean's "Icon of the Seas" is in Port Miami getting ready for its maiden voyage into the Caribbean. NBC News correspondent Sam Brock got a firsthand look at the breathtaking ship on TODAY on before it heads out to sea.

Here's what to know about the record-setting cruise ship.

How big is the Icon of the Seas ship?

A seven-year building process in Finland resulted in a ship that's 1,198 feet long and features 20 decks. It can carry more than 7,000 passengers, and combined with the crew, will hold nearly 10,000 people — the size of a small city.

At 250,800 gross tons and nearly 1,200 feet long, it makes the Titanic look like a tugboat. For comparison, the Titanic was 882.9 feet long and 46,328 gross tons.

What are some of the amenities on the Icon of the Seas?

There are eight "neighborhoods" geared to all different experiences, from the shopping area of "Central Park" to the pools and cabanas of "Chill Island."

They also are in proximity to one another so parents can relax in the pool while the kids go flying down one of the six slides in the nearby water park area of "Thrill Island."

“You’re not competing with another cruise, you’re competing with any other vacation a family would want to do," Royal Caribbean senior vice president Jay Schneider told Brock on TODAY.

"So we purposely put a more adult-centric pool next to the slide structure so you know mom, dad can sit and immerse in the water while the kid goes on like 50 slides."

In keeping with the theme of the ship, a bar named "Swim & Tonic" is the largest swim-up bar ever put on a cruise ship, according to Schneider.

There also is a three-story glass structure known as "The Pearl," which Schneider said is the world's largest "kinetic" art sculpture.

The vessel also includes a theater that features performances of Broadway's "Wizard of Oz."

For the more adventurous, there's the "Crown's Edge" walk, which Brock tested out on TODAY. He strapped into a harness that took him along a zipline that allows passengers to dangle along the side of the ship, 150 feet above the water.

How much does a trip on the Icon of the Seas cost?

A seven-night round trip from Miami to the eastern Caribbean that includes a stop at Royal Caribbean's private island in the Bahamas costs an average of $2,019 per person, according to the cruise line's website . It's an average of $1,809 for the package without the stop at the island.

That package also includes stops in St. Thomas and San Juan, Puerto Rico. The demand for that journey is so overwhelming that the earliest trip currently being booked is for Oct. 11, 2025.

There's also a trip to the western Caribbean for $1,759 per person with a stop at the island, which is called Perfect Day at Coco Cay.

When is the Icon of the Sea's release date?

The maiden voyage for the gargantuan vessel is coming up on Jan. 27, leaving out of Port Miami.

Royal Caribbean is taking bookings for the alternating trips to the eastern and western Caribbean, with the earliest available being a seven-night trip that departs on Feb. 24 and costs an average of $2,297 per person, according to its website.

Largest Cruise Ships

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.

CruiseMapper's list of biggest cruise ships includes all vessels with gross tonnage/volume over 150,000 GT-tons .

Each one of these behemoth ships is an engineering marvel produced by our contemporary age of fun and super technologies. Kudos to their builders and double kudos to their proud owners who have invested so much in these newbuild projects!

Note: In the following table, all links are internal (CruiseMapper) and redirect to the liner's itinerary schedule where you can compare dates and prices per person (double occupancy cabin rates).

The world's largest river cruise ship is Victoria Sabrina . The 2020-launched riverboat is China-built, owned by Victoria Cruises China and deployed year-round on Yangtze River. The vessel has the impressive volume of 17000 GT-tons, LOA length 150 m (492 ft), width 22 m (72 ft), 7 decks (5 with cabins), 270 staterooms, max capacity 690 passengers plus 195 crew/staff.

Oasis-class - biggest cruise ship in the world ever built

World's currently largest cruise ship class is produced exclusively for RCI-Royal Caribbean andin 2 sub-series - Oasis-Class (Allure OTS, Oasis OTS) and Oasis-Plus (Harmony OTS, Symphony OTS, Wonder OTS). These are sisterships from the fleet of the second- largest cruise shipping company in the world - RCCL-Royal Caribbean Cruises Ltd (as shipowner) that follows only Carnival Corporation (as shipowner).

As to vessels' dimensions, each boasts the unimaginable weight of 227,000-230,000 GT / gross tons, LOA length 362 m (1187 ft) and waterline width 47 m (154 ft). The extreme breadth is over 60 m (198 ft). As the GT is a volume measurement, the ship's actual mass (called displacement) is approx 100,000 tons (the hull alone weighs about 54,000 tons). Surpassing all passenger ship standards, building cost and all previous ship travel vacation concepts, the Oasis-class ships are currently the only passenger shipping vessels of such immense size.

Other interesting numbers are the above waterline height (72 m / 236 ft), depth (23 m / 74 ft below waterline), 16 passenger decks, draft/draught (9,3 m / 31 ft), cruising/service speed 23 knots (26 mph / 42 kph), capacity 5400 passengers at double occupancy (max 6296 / 6870) and officers+crew capacity 2165.

The world's biggest cruise ship propulsion system guarantees the perfect maneuverability by 3 rotatable Azipod thrusters (suspended under the ship's stern), each with a huge electric motor and a 6 m (20 ft) propeller. The ship offers great stability due to its enormous size. And in times of need - there are 18 lifeboats, each with a capacity of 370 people.

Oasis-Plus class is also currently the world's most technologically advanced and energy-efficient cruise vessel ever built. It is equipped with a new-generation exhaust gas cleaning system (multi-stream scrubbers) and with a hull lubrication system allowing the ship to float on air bubbles (created around the hull) thus reducing drag and increasing fuel efficiency.

Regarding cruise accommodations , this class of vessels has some of the largest suites at sea - measuring 150 m2 (over 1600 ft2, balcony included). Another signature feature is the 7 "neighborhoods" (theme-park-like areas), 5 large swimming pools, a huge casino, a full-size volleyball/basketball court, large-capacity bars, and lounges. Oasis-Plus ships additionally have waterslides (created by Aquatic Design & Engineering) and a total of 23 "water fun" areas (swimming pools, large-size outdoor jacuzzies, waterslides, flowriders/surf simulators). The stern-located Ultimate Abyss water slide is 150 ft (45,70 m) above sea level. 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.

These phenomenal ships were manufactured by STX Europe (shipyard Turku Finland / Oasis-class) and in by STX France (shipyard Saint-Nazaire France / Oasis-Plus). The new Oasis ships are 2,15 m (7 ft) longer.

Biggest Carnival cruise ship - "Carnival Pinnacle" class

Watch this amazing YouTube video about the "Carnival Pinnacle cruise ship". The project was designed by the Italian shipbuilder Fincantieri as their biggest ever passenger ship - GT tonnage 200,000 tons, capacity 6000 passengers, length 380 m (1246 ft), The "Pinnacle Project" was initiated by Carnival Corporation in 2004 to tip the scales in the "Carnival vs Royal Caribbean" competition.

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.

The 20 Biggest Cruise Ships in the World in 2023

By: Author Carrie Ann Karstunen

Posted on Published: March 1, 2022  - Last updated: January 6, 2023

Cruise ships have been getting bigger—and adding lots of attractions that were unheard of just a few years ago. To help you pick which megaship is right for you, I’ve rounded up the 20 biggest cruise ships in the world in 2023.

Along with a ranking of the top 20 cruise ships by size , I’ve included important stats and unique features for each ship. If you’re considering sailing on one of the biggest cruise ships in the world, you’ll want to read this guide before you choose!

How do we determine the size of cruise ships for comparison?

Cruise ships can be measured by a variety of factors. You might assume that a ship’s size is determined by its length, weight, or even its passenger capacity.

But the size of a cruise ship is generally determined by gross tonnage —and (confusingly) that’s not a measurement of weight!

Gross tonnage, or GT, is a measure of the ship’s internal volume . To calculate GT, first a ship’s volume is calculated by measuring from keel to funnel to the outside of the hull framing. That number (in cubic meters) is then run through several mathematical formulas to determine GT. (I won’t go into all of that here, but if you’re interested the US Coast Guard has a simplified guide to measuring gross tonnage ).

The world’s 20 largest cruise ships in 2023

Currently, the top 20 biggest cruise ships have four sets of ties in the rankings, all between sister ships that share the same cruise line and class. So although we’ll start our list at #16, there are twenty ships in total!

Cruise fans will notice there are several new ships on the list this year. Have any of these newer ships bumped your favorites down in the rankings? Read on to find out!

16. (tie) MSC Seascape

• Cruise line: MSC
• Year built: 2022
• Gross tonnage: 170,412
• Length: 1112 ft / 339 m
• Max. beam: 135 ft / 41 m
• Staterooms: 2270
• Max. passengers: 5877
• Passenger decks: 15

Just making this year’s list of the world’s 20 largest cruise ships, MSC Seascape is tied for #16. The second Seaside EVO class ship launched by MSC Cruises in just over a year, Seascape features a glam New York City vibe.

The ship’s four-story Atrium is at the heart of the action on board, and boasts a sparkling staircase set with 10,000 Swarovski crystals—the perfect spot for a photo op on formal nights !

But MSC Seascape isn’t all glitz and glamour—the family-friendly ship offers 13 pools and water features and more than 140,000 square feet (13006 m²) of public outside space. Kids will love Pirates Cove Aquapark , a play space with slides, a rope bridge, and plenty of water sprayers and dumping buckets to beat the heat.

Seascape is also the first ship to feature the new thrill ride Robotron , a robotic virtual rollercoaster ride perched on the top deck.

Foodie guests on MSC Seascape will enjoy the ship’s eleven restaurants, including a massive Market Place Buffet and several specialty dining venues grouped together at Chef’s Court .

16. (tie) MSC Seashore

• Year built: 2020 (launched 2021)
• Max. beam: 134.5 ft / 41 m

Almost identical to her sister ship Seascape , MSC Seashore is tied for #16 on the list of the largest cruise ships. The first in the EVO subclass of MSC’s Seaside class ships, Seashore and her sister are larger than other ships in their class and offer expanded outdoor spaces.

As an EVO ship, MSC Seashore offers improved technology to increase efficiency and reduce her carbon footprint. The energy-efficient equipment includes an advanced wastewater purification system and Safe Air , a new sanitation system that eliminates viruses and bacteria.

Seashore was purpose-built for the American market, but still offers the European flair that MSC is famous for. Guests can enjoy a taste of Italy at the ship’s Venchi 1878 gelato bars , offering twenty flavors of the decadent frozen treat in flavors like tiramisù and stracciatella.

MSC Seashore also features a gorgeous aft infinity pool—one of the largest at sea—with luxurious submerged sunbeds. The spot is a tranquil adults-only oasis by day, but it comes alive in the evening as the setting for the always-popular Silent Disco .

15. (tie) MSC Bellissima

• Year built: 2019
• Gross tonnage: 171,598
• Length: 1,036.2 ft / 315.83 m
• Max. beam: 141 ft / 43 m
• Staterooms: 2,217
• Max. passengers: 5,686
• Passenger decks: 14

Tied for the fifteenth spot in the list of the world’s largest cruise ships, MSC’s Bellissima is as tall as thirteen double-decker buses!

Perfect for a family cruise, Bellissima offers a wealth of kids’ activities for children aged one through seventeen. Parents can track kids’ whereabouts on board via an RFID bracelet synced with MSC’s app. For adults who want to enjoy a leisurely meal, there’s the Happy Dinner program where the little ones are escorted to the kids club as soon as they finish eating!

MSC Bellissima is home to a thrilling Grand Canyon-themed waterpark with three waterslides—two racing tubes as well as a champagne bowl-style slide. The younger set will love the Aquaplay spray area, and guests of all ages can climb the Himalayan bridge, a rope course that crosses the ship high above the water.

Guests aboard Bellissima also have access to an electronic cruise assistant, similar to Siri or Alexa. A first in the cruise industry, Zoe —who speaks seven languages and adapts to each passenger’s preference—provides information and help booking shows, spa treatments, and shore excursions, as well as notifications of events and promotions.

15. (tie) MSC Meraviglia

• Year built: 2017
• Staterooms: 2,244

On Meraviglia entertainment options abound—the Broadway Theatre hosts six unique shows each cruise, along with the Carousel Lounge where you can experience Cirque du Soleil at sea. The crew also puts on an impressive amount of activities and events, so there’s always something to do on a sea day .

The ship’s Amusement Park has a full-size bowling alley, 4-D cinema, F1 simulators, an arcade, as well as a sportplex that becomes a disco spot for young cruisers in the evening.

What is the largest cruise ship in the world?

D oes size really matter? The cruise industry thinks so. For more than a century, cruise lines have competed to claim the title of world's largest cruise ship.

When it set sail in 1912, ill-fated Titanic was the largest and grandest passenger vessel of its time. But since 2009, when Royal Caribbean debuted its first Oasis Class ship , those superlatives have applied to vessels more than five times Titanic's size.

For more cruise guides, news and tips, sign up for TPG's cruise newsletter .

Today, the largest cruise ships are floating cities, offering a plethora of bars and restaurants, expansive spas and sun deck retreats. They feature scores of recreation opportunities, including zip lines, surf simulators , rock climbing walls, ice-skating rinks, escape rooms, laser tag, top-deck go-karts , virtual reality gaming and even roller coasters .

So, what is the largest cruise ship in the world, and how do other cruise ships compare? Here's a quick rundown of the world's biggest cruise ships by both gross registered tons and maximum passenger capacity. Unsurprisingly, Royal Caribbean's Icon Class and Oasis Class dominate the top five in both categories, with only two other lines joining Royal Caribbean.

Note: This article excludes ships from lines like Costa Cruises, P&O Cruises and Aida, which do not cater to the North American market.

What is the world's largest cruise ship?

Currently, it's Royal Caribbean's Icon of the Seas. At 250,800 gross registered tons and carrying up to 7,600 passengers (plus 2,350 crew members), the ship is a true behemoth. It includes neighborhoods that feature everything from waterslides, an indoor AquaTheater, a carousel and an adults-only sun deck to lavish suites, retail shops, thousands of live plants and more than two dozen bars and restaurants.

What is the biggest cruise ship in the world today (2024)?

Currently, the largest cruise ship in the world by both tonnage and passenger capacity is Royal Caribbean's Icon of the Seas. It takes the title from fleetmate Wonder of the Seas. Several other Royal Caribbean vessels — including Freedom Class and Oasis Class namesakes Freedom of the Seas and Oasis of the Seas — were also the largest at one time.

What is the world's biggest cruise ship price?

Royal Caribbean paid about $2 billion to build Icon of the Seas. At press time, the least expensive cabins on Icon of the Seas started at $1,252 per person, including taxes and fees, for a seven-night voyage ($179 per person, per night). If that's out of your price range, check out my recommendations for ships to try instead of Icon of the Seas .

What cruise ship is 5 times bigger than Titanic?

All of the ships in Royal Caribbean's Oasis Class and Icon Class are at least five times larger than Titanic was, in terms of size. As far as passenger numbers, Titanic had capacity for 2,453 people, while Icon of the Seas can hold 7,600, meaning the latter holds more than three times the number of passengers Titanic was able to.

What is the largest cruise ship capacity?

Icon of the Seas can hold up to 7,600 guests at maximum capacity or 5,610 guests on a double occupancy basis (two people per cabin). The ship also employs more than 2,300 crew members. That means the ship can carry nearly 10,000 people when it's fully crewed and every passenger bed is occupied.
