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.

With every year comes bigger and grander cruise ships.

Just when you think cruise ships can't get any larger, a major cruise line unveils yet another longer, taller and grander state-of-the-art vessel – with the capacity to carry the population of a small town. To put the size of today's megaships into perspective: They often stretch three times longer than a 120-yard football field, and some feature nearly two dozen decks or measure more than 215 feet wide.

So, if you're looking for a vacation aboard a large-scale vessel, consider booking a voyage on one of the biggest cruise ships in the world. With cutting-edge technology and entertainment, world-class dining, and endless attractions and activities for cruisers of all ages, you may not even want to leave the ship.

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.

Royal Caribbean's new Icon of the Seas will be world's biggest cruise ship, with room for nearly 10,000 people

Royal Caribbean has done it again. The cruise line has announced it's building the largest cruise ship ever — even bigger than its recently unveiled Wonder of the Seas, the current record-holder for world's largest cruise ship . The new Icon of the Seas will carry 7,600 passengers at maximum occupancy (or nearly 10,000 people when you account for the crew) when it first sets sail with guests Jan. 28, 2024.

When completed, the ship will be 20 decks high and 1,198 feet long and measure 250,800 gross tons. To compare, Wonder of the Seas is 1,188 feet long and measures 235,600 tons. It carries 7,084 passengers at maximum occupancy (all berths filled).

However, Icon of the Seas will only have 2,805 cabins compared to Wonder's 2,867 — despite carrying more people when all berths are filled. That's because Royal Caribbean is targeting this ship to families and planning for the ship to sail with more cabins carrying more than two passengers.

Like Wonder, Icon of the Seas will have eight neighborhoods (areas of the ship themed around a type of activity). Five are new to Icon, and three are returning from previous Oasis-class ships (such as the Suite Neighborhood, Royal Promenade and Central Park). As befitting the world's new largest cruise ship, Icon of the Seas will have plenty of mind-blowing and biggest-ever attractions, including:

Category 6, the largest water park at sea: Located in the new Thrill Island top-deck neighborhood, this active area features a whopping six water slides, including an open free-fall slide, the tallest drop slide at sea, family raft slides that accommodate four riders at once and two mat-racing slides. This area of the ship also includes a ropes course-style attraction around a giant version of the ship's crown-and-anchor logo.

AquaDome, an indoor AquaTheater: Royal Caribbean has taken the back-of-the-ship AquaTheater found on its Oasis-class ships (home to acrobatic and diving shows) and brought it forward, up to the top of the ship and indoors into a multipurpose space with huge floor-to-ceiling windows, offering 220-degree views. Also in this space will be restaurants and bars. Royal Caribbean fans might notice some similarities with the Two70 entertainment space from the line's Quantum-class ships.

Three-story Ultimate Family Townhouse: The evolution of Royal Caribbean's enormous two-deck-high Ultimate Family Suite found on Oasis-class ships will be Icon's three-story Ultimate Family Townhouse. The giant suite will not only feature adult and kid bedrooms, family-focused living areas and loads of sea views, but it will also have a fenced-in outdoor backyard play area with direct access to Surfside, the new neighborhood dedicated to young families.

Surfside will feature splash areas for babies and kids, as well as relaxing pools and lounge spaces for parents, family-friendly eateries and shops, a new pool-themed version of Royal Caribbean's carousel and a bar with "mommy and me" matching mocktails for kids and cocktails for grownups. Additional new family cabins and suites will surround the Surfside neighborhood and the area will have easy access to the Adventure Ocean kids club and other ship areas popular with families. (It will also have an entrance slide.)

First suspended infinity pool and swim-up bar at sea: Above Surfside is an infinity pool, suspended over the back of the ship. It's surrounded by the Hideaway, a beach club-inspired neighborhood full of terraced sun decks and convenient bars.

Four of the ship's seven pools will be found in the three-deck Chill Island pool area, with plenty of ocean views from the watery play spaces. Among the pools is Royal Caribbean's first swim-up bar; another is what Royal is claiming to be the largest pool at sea. There will also be an adults-only pool area and another infinity-edge pool. Cabanas to rent will be available in this neighborhood.

True ship-within-a-ship enclave with largest-ever Suite Neighborhood: On Wonder of the Seas, Royal Caribbean came the closest to creating an exclusive, self-contained suite enclave, akin to Norwegian Cruise Line 's The Haven or MSC Cruises ' Yacht Club. That concept comes into its own on Icon of the Seas with the line's largest-ever Suite Neighborhood that's three decks high and features a two-story Coastal Kitchen restaurant (exclusive to suite guests and Royal Caribbean's most loyal guests) and The Grove, a new multilevel sun deck with a pool, hot tub and Mediterranean restaurant.

First LNG-powered ship for Royal Caribbean: Icon of the Seas will be the fleet's most sustainable ship. It's the first Royal Caribbean ship to be powered by liquefied natural gas and equipped with fuel cell technology. It's also able to hook up to shoreside power when available in port, has a state-of-the-art waste management system and can convert engine heat to power.

Fan favorites returning to Icon of the Seas include the shopping/dining/drinking complex of the Royal Promenade; the greenery- and restaurant-filled Central Park; miniature golf, an ice skating rink, rock climbing and the FlowRider surf simulator; and popular restaurants, such as Giovanni's Italian Kitchen & Wine Bar (now on the Royal Promenade) and Izumi for Asian cuisine (now in Central Park with an expanded hibachi space).

Icon of the Seas will have 28 cabin and suite types to suit every type of traveler, including the aforementioned family cabins, inside cabins with extra-large walk-in closets and panoramic ocean-view rooms in the AquaDome.

Deal watch: Royal Caribbean is selling fall cruises for under $100

The ship will sail weeklong Eastern and Western Caribbean itineraries, and each will visit Royal Caribbean's private island, Perfect Day at CocoCay , with its multiple beaches and Thrill Waterpark, home to 13 waterslides. Bookings open Monday for Royal Caribbean's past guests and Tuesday to the public.

Icon of the Seas is just the first of three sister ships Royal Caribbean has on order for delivery by 2026 that will represent an all-new class of vessels at the line — to be called the Icon class. The line also has one more Oasis-class ship on order for delivery in 2024.

Inside icon of the seas, the world’s largest cruise ship.

They like big boats and they cannot lie.

For many of the first passengers on the world’s largest cruise ship, Royal Caribbean’s Icon of the Seas, the onboard reality of the $2 billion behemoth lived up to the over-the-top hype.

During back-to-back preview sailings from the Port of Miami in late January, travel agents, special guests, members of the media and selfie-snapping influencers giddily explored as much as they could of the 20-story floating city that boasts eight distinct neighborhoods — and can hold nearly 10,000 passengers and crew at full capacity.

As they ate and drank across the ship a shared sentiment formed: Big is indeed beautiful.

“I think it’s definitely a game-changer,” said Tywana Minor, founder of Live Travel Go, a boutique travel agency based in Atlanta. “You can literally be on the ship for a few days and still not even experience everything.”

The first bunch on board explored the myriad offerings with a sort of collective awe. Couples clinked flutes of champagne at the walk-up Bubbles bar in the Central Park neighborhood, one of 40 bars and restaurants on board.

“You can literally be on the ship for a few days and still not even experience everything” Tywana Minor, founder of Live Travel Go

Adults giggled like nervous adolescents as they blasted down water slides with names like Frightening Bolt and Storm Surge in the 17,000-square-foot water park. Pint-sized passengers, meanwhile, found nirvana at Surfside, a family-centric area complete with a beach-themed carousel and wading pool.

A few lucky souls even had the good fortune to snag perhaps the most coveted reservation on the high seas: the 38-seat Empire Supper Club, an eight-course dinner complete with cocktail pairings and live jazz. The fine-dining experience, which costs $200 per person, is fully booked for the next few months.

But it wasn’t just Icon’s splashy main attractions wowing passengers: Surprises awaited around seemingly every corner of the 1,198-foot ship, including pop-up piano performances, magicians and a duo of donut-costumed employees at the breakfast buffet every morning pointing guests toward rows of sinks and reminding them to “washy washy before yummy yummy!”

For many passengers, adjusting to Icon’s staggering size — it’s nearly as long as four New York City blocks — presented a learning curve in itself. Even with signage everywhere, getting lost at some point was a given. Furthermore, the ship’s design — a vast open-air interior with elevators located forward and aft but not in the middle — almost guarantees that passengers will hit (or exceed) their daily step count.

“If you don’t like walking around a lot, this ship is not gonna be for you,” said Linda Miranda , a Newburgh, NY-based travel franchise owner with Cruise Planners.

As an antidote to the go-go-go vibe, Icon’s massive square footage also includes plenty of tranquil nooks and crannies ideal for kicking back and catching your breath: bed loungers overlooking the ocean; cornucopias of outdoor couches and chairs across various decks; and cozy, nest-like booths in the AquaDome, an area featuring a waterfall and wraparound ocean views.

“There are so many spaces that you’re not going to feel the 7,600 passengers it can hold fully occupied,” Miranda said.

To escape the sensory overload altogether, retreat to their staterooms. There are 28 room categories; the most basic accommodations are 157-square-foot interior plus cabins, with rates starting at $3,600 per week for two people.

Meanwhile, one-percenters can splash out with the three-story Ultimate Family Townhouse, which spoils eight guests with amenities like a private patio, outdoor hot tub, in-suite slide, cinema and popcorn machine, and kids’ room. The suite costs, on average, $100,000 per week.

So far, passengers are showing an insatiable appetite for Icon and its outsized experience. When the ship was first announced in October 2022, it broke records as the largest booking day and week in Royal Caribbean’s then 53-year history, according to the cruise line. And the remainder of 2024 sailings are almost sold out, a Royal Caribbean spokesperson confirmed.

But since Icon is the first of a new class of megaships by Royal Caribbean — two more are on the way, with Star of the Seas scheduled to debut in August 2025 — there’s plenty more big fun on the horizon. It’s a prospect that has the chubby chasers of the cruise community twitterpated.

“These news ships, I don’t know how they keep building them bigger and bigger,” said Howard Schildhouse — a retired accountant who writes about his travels on his blog, “ It Must Be Wanderlust ” — “but they do.”

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

7 wild facts about the world’s biggest cruise ship

The icon of the seas has more than five times the tonnage of the titanic.

Is it a dream vacation or nightmare scenario? Depictions of the world’s largest cruise ship — the Icon of the Seas , setting sail in January — have the internet in an uproar.

One image especially seems to have captured the public’s imagination: a rear-end view that looks like a towering layer cake topped with silly string.

“The physical manifestation of Barbenheimer,” wrote one Twitter user, referring to the releases of “Barbie” and “Oppenheimer,” about the development of the atomic bomb, on the same day. “Nightmare clown lasagna,” wrote another.

Many invoked the Northern European painter Hieronymus Bosch , Dante’s “Inferno ” and hamster cages . A smattering said it looked like actual fun .

The "Icon Of The Seas" sets sail in January 2024. 5610 passengers, 2350 crew members, 5 times larger and heavier than the Titanic, 19 floors with more than 40 bars, restaurants and bowling alleys. What a monstrosity! pic.twitter.com/igoQRUZ3nP — Ray Monk (@Raymodraco) July 9, 2023

Tanner Callais, founder and editor of cruise information site Cruzely , said in an email that it’s no surprise the behemoth is creating buzz.

“Looking at those renderings, I think the ship almost looks like a cartoon with the huge water park at the back,” he said. “It’s just unreal that something like that can be built to sail the ocean.”

Whatever the impression it’s leaving, cruise line Royal Caribbean International says Icon, which completed initial sea trials in June, is selling like mad. The company reported its single largest booking day when reservations opened in October; sales have since set two more records.

The Miami-based company is no stranger to setting records: Royal Caribbean has brought several “world’s largest” ships to market, notably the Oasis of the Seas in 2009, which dwarfed all others in its wake. Additional iterations have been slightly larger than the original, and even Icon of the Seas will only be 10 feet longer than its closest runner-up.

Travel adviser Danny Genung, CEO of Harr Travel , said he was up in the middle of the night booking trips for clients when reservations opened. He snagged a spot on the inaugural voyage for himself.

“There’s never been a ship launch like this in the industry,” he said.

Here are seven standout stats about the ship.

10 things you didn’t know were on cruise ships

It can hold 5,610 passengers.

That’s not including crew. That’s a few hundred more people than the population of Bar Harbor, Maine, which is U.S. News & World Report’s top small town in the United States to visit this year.

Crew adds another 2,350 to the total. And because ships are designed to accommodate more than two people per room with additional beds for families or groups, the total guest capacity is actually a whopping 7,600. When Oasis of the Seas was introduced as the biggest ship in the world in 2009, its capacity at double occupancy was 5,400 guests.

The average capacity for the 44 ships being introduced between this year and 2028 is 2,749 passengers, according to the Cruise Lines International Association.

It’s nearly 1,200 feet long.

The ship is only 10 feet longer than previous biggest-ship record-holders, at 1,198 feet. That’s the equivalent of more than three football fields or nearly four Statues of Liberty, pedestals included.

To visualize another way, the ship’s length is just 52 feet shorter than the height of the Empire State Building , not including the spire.

It has more than five times the tonnage of the Titanic.

Cruise ships are ranked according to gross tonnage, the measure of internal volume. This is where Icon of the Seas really outshines the competition, at 250,800 gross tons. The next-closest is Royal Caribbean’s Wonder of the Seas, which comes in at 235,600.

To compare, the Titanic was 46,329 gross tons.

Stomach viruses are back up on cruise ships, with hundreds falling ill

It has more than a dozen decks.

Icon of the Seas will feature 20 decks, 18 of which are for guest use. Those decks encompass eight “neighborhoods,” including a Central Park packed with live plants; a massive water park; a three-deck cluster of pools; a massive dome featuring a waterfall and performances; and an area for families with young kids to play and eat.

The next-largest ship in Royal Caribbean’s fleet, Wonder of the Seas, has 18 decks, all but two of which are for guests.

There’s a pool for every day of the week.

There will be seven pools on the ship, including a swim-up bar, suspended infinity pool and what Royal Caribbean describes as the “largest pool at sea.”

Voyager of the Seas , which was the world’s largest in 1999 when it launched, has three pools.

It has the biggest water park on the water.

Royal Caribbean is boasting that Icon will have the “largest waterpark at sea,” called Category 6. That refers to hurricane strength (which tops out at Category 5) but also the six slides on board. There’s an open free-fall slide, a 46-foot drop slide, family raft slides and a pair of mat-racing slides.

“Everybody now has a waterslide or two but having a water park with six slides that would be as good on land as they are on sea, it’s really unheard of,” Genung said.

In a 2022 roundup of best cruise ship water parks, Cruise Critic highlights Carnival. Many of its ships offer a trio of slides. MSC Cruises comes close to Icon’s number on some of its recent ships, offering four or five slides, and the cruise site notes that some of Norwegian Cruise Line’s ships have up to five waterslides.

Love that cheap cruise price? Don’t forget the boatload of fees.

There are 40-plus places to eat and drink yourself silly.

Cruise ships have expanded their food and beverage options in recent years far beyond just a buffet, main dining room and pool bar. Icon will offer more than 40 ways to “drink, dine and be entertained,” including 15 bars and nightlife experiences and more than 20 dining options.

Restaurants on board run the gamut, with an eight-course supper club experience, an all-day brunch spot, sushi, street food, a steakhouse and, yes, buffets. Reflecting cruise passengers’ appetite for variety, this total is actually on par with the current record-holder, Wonder of the Seas.

For a land-based comparison, Atlantis Paradise Island in the Bahamas says on its website that it offers 21 restaurants and 19 bars and lounges.

Genung, the travel agency CEO, said he has clients who say the ship looks amazing but seems too big for them.

“You get all the scope of reactions: ‘That’s cool, that’s crazy; I can’t wait to do it, I would never want to do that,’” he said. But he said that, especially for multigenerational families who want to travel together, it’s a great fit.

“The thing with this is it’s a perfect cruise for lots at different people at different times in life,” he said.

More cruise news

Living at sea: Travelers on a 9-month world cruise are going viral on social media. For some travelers, not even nine months was enough time on a ship; they sold cars, moved out of their homes and prepared to set sail for three years . That plan fell apart, but a 3.5-year version is waiting in the wings.

Passengers beware: It’s not all buffets and dance contests. Crime data reported by cruise lines show that the number of sex crimes has increased compared to previous years. And though man-overboard cases are rare, they are usually deadly .

The more you know: If you’re cruise-curious, here are six tips from a newcomer. Remember that in most cases, extra fees and add-ons will increase the seemingly cheap price of a sailing. And if you happen to get sick , know what to expect on board.

Cruise Ship Passenger Capacity

View cruise ship ratings and learn what is average/normal and max cruise ship passenger capacity. Cruise ships capacity (passengers and crew/hotel staff) and space ratios of the world's most famous ships are sorted alphabetically by the names of their owners (companies, lines, and operators) according to the official cruise ship data.

Most online travel media publish ship ratings based on onboard amenities (dining/entertainment), itineraries/destinations, special/unique facilities, and experiences. Some ratings are based on website visitors' feedbacks and conducted polls. However, while the latter ratings could by easily manipulated, "expert review" based ratings could be only suggestive as top-rated will be always the largest liners and the  newest vessels .

Cruise Ship Capacity

The "full" cruise ship passenger capacity is based on double occupancy (2 guests per cabin). The cabin's capacity varies according to stateroom's type, category, and also by line and ship. A standard passenger ship cabin usually accommodates 2 or 3 guests, but there are some "smaller" and "bigger" exceptions.

Our survey also includes smaller ships (under 500 passengers), and some ships are intentionally omitted from the big table to be included in the small one (about passenger capacity of top luxury cruise ships, with emphasis made on their highest guests-to-crew ratio. If searching for a particular vessel, use the Ctrl+F key combination and type the name in the search box. Good to know things:

• Ships will sail at varying capacities depending on itinerary and season.
• The average cruise ship passenger capacity is around 3,000 guests for ocean liners and around 150 guests for bigger river cruise ships.
• The largest cruise ship passenger capacity is 5,412 (at double occupancy) and 6,318 max capacity if all berths are occupied. And, of course, these big numbers are part of the specifications of the first in the  list of the biggest cruise ships in the world  - the Oasis ship of Royal Caribbean International.
• Single cruise cabins (called also "studios", or "solo cabins"), though rarely available, offer some of the cheapest rates for solo travelers by avoiding the double occupancy policy of all the major cruise ship companies, with the range of single supplement rates being between 50 and 100% (depending on line and ship).
• Family suite cruise accommodations generally have the biggest passenger capacity (up to 6 guests) and are some of the most expensive cabin categories (again, not available on all ships). Cheap suites are available on most Carnival, Royal Caribbean, MSC, and Costa ships.

Max (largest) passenger capacity of a cruise ship would signify this ideal financial situation, when all the berths, plus all upper and lower bunks, "Pullman" beds and single and double sofa beds (available in types and numbers according to the ship's cabin grades) are all occupied by the most numerous crowd the ship can ever gather on board. However, on most of the sailings, even the full-ship capacity (at double occupancy level) is not reached. This automatically opens the "big ships doors" for great deals, like kids sail for free, buy one get one free, free cabin upgrades, bonus amenities, and also huge price discounts on luxury cruise deals. For more info, you can read our survey on unsold cruise cabins/cheap cruise upgrades .

Cruise passengers-to-space ratio

The ship's "space ratio" (by definition) is the enclosed space (measured in ft3/cubic feet) per passenger. A ship of 45,000 GT (gross tonnage) with capacity 1,000 passengers will have a space ratio 45 (or 45ft3=45000/1000). So if your ship has generally smaller cabins but very large public spaces, she will have a higher space ratio, and the higher the space ratio number, the more guests will enjoy a sense of spaciousness on board.

Cruise Ship Ratings

0 (or no Stars) doesn't mean the ship is the worst ever, but not yet rated.

"Specialty" means usually a smaller ship offering deals on adventure or expedition cruises. Emphasis on itinerary/destination and unique experiences rather than onboard services/amenities/activities. Cabins are modest (as size and amenities), but also comfortable.

3 Stars mean "Contemporary" and big resort-like experiences on bigger ships with a multi-generational clientele, a huge variety of family and kids programs, at least 2 swimming pools, huge fitness/spa centers, distinct nightlife (clubs, a casino, deck parties), several dining options. Cabins range from cozy Inside to large family suites and many connecting/adjoining rooms. Itineraries from 3 to 7-night in length (repeating, round-trip) leaving from big and popular ports.

4 Stars mean a "Premium" product, medium-sized ships with higher guest-to-crew ratios compared to similar-sized mainstream ships. The onboard experience - fewer kids, larger than average cabins with upgraded (luxurious) amenities, high-level of service, dining, and entertainment, extensive enrichment programs, a luxury spa, longer itineraries (from 7 to 14 and even 21-night in length).

5 Stars mean a "Deluxe" product, from medium-size to small cruise ships with deluxe staterooms, bedding and cabin amenities, impeccable service, multiple specialties (gourmet) dining options, also less entertainment and onboard activities. The itinerary is mostly port-intensive, and longer than 10 nights, with deals on back-to-back cruises .

6 Stars mean "Best Luxury" on small ships, intimate cruising experiences, highest guest-to-crew ratios (fewer guests). These are mostly ships with all-inclusive cruise deals - gratuities and beverages (often alcohol) and gourmet (specialty restaurant) dining are all included in the fares (often with shore excursions and tours), spacious staterooms and public spaces, the highest level of service. Many of these are all-suite ships (with different category suites). Port-intensive itineraries and exotic destinations, often offering deals on Around the World Cruises .

All cruise ship ratings are based on CLIA (Cruise Lines International Association) categorizations, and reviews from "WMPH Vacations" (iCruise, AlaskaCruises, EuropeCruises, HawaiiCruiseOutlet, RegentCruises, and CruiseCheap) specialists and advisors. Cruise ratings also may vary on the ship's age, size, cabins/venues/amenities, passenger feedback, etc. Besides CLIA and WMPH, other cruise vessel rating sources are Berlitz Guide, Fieldings Guide, Sterns Guide, CruiseCritic, CruiseReviews, and CruiseMates.

Cruise ship star ratings meaning

5,5 stars rating - a top luxury cruising, impeccable and highly personalized service, finest quality food & amenities; attention to detail, perfect maintenance, spacious accommodations, gourmet cuisine, the highest level of service, authentic furnishings, top of the line fitness & spa facilities.

5 stars rating - the highest level of food/service in a premium cruising market, high-quality meals, attentive service, well-equipped staterooms (not necessarily large), list of cabin amenities include bathrobes; butler service, public spaces are with beautiful decors.

4,5 stars rating - friendly decor, good maintenance, full range of onboard activities.

4 stars rating - best overall experience, above-average food & service, satisfactory entertainment.

3,5 stars rating - an average overall experience, very small to large accommodations, good service, delicious food, kids facilities without dedicated areas, mediocre entertainment.

3 stars rating - modest experience on an older cruise ship, may not have balcony cabins, mediocre food & lack of proper service, expect interesting destinations/itineraries.

2 stars rating - the ship is comparable to a low-budget hotel, a major refurbishment needed for refit and renovation of public areas and staterooms, lousy service (the staff will only supply the most basic service), itineraries with little or no popular (cheap charging) ports of call.

I sailed on Royal Caribbean's 2 largest cruise ships. They were shockingly similar for the $1,000 difference

Posted: April 3, 2024 | Last updated: April 3, 2024

• Royal Caribbean operates many of the cruise industry's biggest ships.
• Icon of the Seas  launched in January, dethroning its predecessor, Wonder of the Seas, as the world's largest.
• Here's how the two mega-ships compare in size, neighborhoods, amenities, dining, cabins, and costs.

Icon of the Seas, Royal Caribbean's new mega-cruise ship darling, was deemed a success before it was even built.

In January, the highly anticipated vessel — complete with more than 40 bars and restaurants, a six-slide waterpark, and a waterfall — set sail, dethroning its less than two-year-old precursor, the Wonder of the Seas , as the world's largest cruise ship.

Before its debut, Michael Bayley, the president and CEO of Royal Caribbean International, had already repeatedly called Icon its "best-selling product" yet. The company experienced its largest booking day ever when reservations opened for Icon of the Seas more than a year before its launch, it said

Despite all of this fanfare, you might be surprised by how similar it is to its predecessor.

I've sailed on both ships. Let's see how Icon and Wonder compare in six categories: size, neighborhoods, amenities, dining, cabins, and costs.

Both ships stunt the size of their competitors.

Wonder of the Seas debuted in 2022 as the then-world's largest cruise liner, measuring 235,600 gross-tons, 1,188 feet-long, and 18 decks-tall. The ship can accommodate up to 9,288 people, including 2,204 crew.

Icon of the Seas is, comparatively, 13,063 gross-tons heavier, eight feet longer, and two decks taller. It can sail up to 9,950 people, including 2,350 crew, although it's 52 feet less wide than its predecessor.

Both vessels feel more like amusement parks than traditional cruise ships.

Royal Caribbean invited me on complimentary, non-revenue sailings on both ships: two nights on Wonder in late 2022 and three nights on Icon in January.

I spent most of my time lost, overwhelmed, and exhausted.

It's no surprise both ships are operating weeklong itineraries this year. Any less, and you might not have time to experience all the activities and restaurants on your list.

Like other Royal Caribbean ships, Wonder and Icon have eight 'neighborhoods' that serve separate purposes.

The new ship shares three of Wonder of the Seas' neighborhoods : Central Park, Royal Promenade, and Suite.

Icon's other five — Thrill Island , Surfside, Hideaway, Chill Island, and AquaDome — are a first for the cruise line.

Many of the ships' amenities overlap, but in differing quantities.

Wonder has three waterslides. Icon has a six-slide waterpark complete with rafting and racing options.

Both have increasingly popular cruise amenities like decks-long dry slides, mini-golf courses, rock climbing walls, and playgrounds.

But instead of Wonder of the Seas' zipline , Icon of the Seas has Crown's Edge, a thrilling agility course with a small zipline that leaves travelers dangling 154 feet above the ocean.

Wonder’s Boardwalk neighborhood was my go-to.

Boardwalk delivered exactly as it had promised: an open-air space grounded by wood-planked floors, a hot dog stand, a sweets store, and kitschy, colorful decor.

Icon of the Seas' Surfside , designed for families with young children, felt like its closest dupe.

Both neighborhoods had a carousel, an outdoor playground, and family-friendly dining. But Surfside was more toddler-friendly, as suggested by the children's water play area and nighttime story readings.

On to entertainment: Both mega-ships have ice skating performances and exciting multi-disciplinary shows at the AquaTheater.

But travelers who enjoy musicals at sea will want to stick to Icon.

Unlike its predecessor, the new ship shows a rendition of Broadway hit "The Wizard of Oz" — Munchkins, a puppet Toto, and a 16-piece live band included.

The layout of Icon's amenities were better than its cousin.

Some of Wonder of the Seas' enticing outdoor amenities — like the surf simulator, zipline, and mini-golf course — are clustered on the deck above and away from the pools and water slides.

This layout might be difficult for parents with children who bounce from one activity to the next. Wouldn't it be easier to have all of these outdoor extras near each other, or at least on the same deck, for parental supervision purposes?

This is where Icon of the Seas excelled: All its exciting open-air activities were adjacent.

The rows of pools flowed perfectly into Thrill Island's waterpark , rock climbing walls, mini-golf course, and Crown's Edge.

The best part? The adult-only Hideaway — which flexes an infinity pool club with a DJ — is right behind Thrill Island, creating a clear separation between parents and their children without being too far from each other.

'Free' options like the buffet and build-your-own tacos and burritos bar are available on both ships.

But you won't find the larger vessel's five-stall food hall or mini-golf-adjacent finger food stand on Wonder.

As expected, Icon of the Seas has more dining options than its predecessor, although there are some overlaps.

Wonder of the Seas has 11 bars and 21 dining venues (9 complimentary and 12 upcharged).

Icon of the Seas has eight more bars, four more complimentary restaurants, and three more specialty dining choices.

Nor will you find the new ship’s plush $200-a-person Empire Supper Club on any other cruise liner.

The multi-course dinner, paired with cocktails and live music, stunts the cost of either vessel's other dinner options.

But if you love Johnny Rockets, you’ll be disappointed by Icon of the Seas.

Restaurants like the popular burger chain and Southern comfort-inspired Mason Jar are only on Wonder of the Seas. Fine by me: My fried chicken at Mason Jar was as dry as a desert.

The younger ship doesn't have Wonder's robot bartender-armed bar either. It does, however, have new watering holes with dueling pianos and live jazz.

Surprisingly, Wonder of the Seas has 65 more cabins than its new cousin.

But several of Icon's 28 stateroom categories are a first for the cruise line.

This includes the new family infinite balcony cabin, which has a small bunk bed nook for children.

Royal Caribbean assigned me an ocean-view balcony stateroom on both ships.

My Wonder of the Seas' cabin was 20 square-feet smaller than the one on Icon. But my bathroom on the latter was so tiny, I accidentally elbowed the walls at almost every turn.

Sailing on the world's largest cruise ship doesn't mean you'll have the world's largest cabin after all.

Wonder and Icon are both operating seven-night roundtrip itineraries from Florida to the Caribbean.

In 2024, Wonder of the Seas is scheduled for year-round sailings from Port Canaveral to the Caribbean and Royal Caribbean's private island, Perfect Day at CocoCay , starting at $700 per person.

Icon of the Seas is spending its first year in service operating nearly identical itineraries but from Miami instead. The cheapest 2024 option is $1,786 per person.

That's a difference of more than $125 per person per day.

"Bookings and pricing for Icon of the Seas can only be described as 'iconic,'" Naftali Holtz, the CFO of Royal Caribbean Group, told analysts in February.

Icon of the Seas’ name speaks for itself.

If your family is looking for a jam-packed kid-friendly cruise with enough amenities to stay entertained for a week, both ships are a great option.

But if you're a seasoned mega-ship-cruiser looking to experience something new, Icon of the Seas is your best bet.

They may be similar, but no other behemoth cruise liner has a waterpark for children and a pool club for adults just dozens of feet from each other.

Introduction

Welcome aboard the world of cruising, where luxury and entertainment meet the vastness of the open sea. For travelers seeking a unique and unforgettable vacation experience, cruise ships offer a perfect blend of relaxation, adventure, and exploration. With their grandiose size and impressive amenities, modern cruise ships have become floating cities, catering to the needs and desires of thousands of passengers. In this article, we will delve into the world of colossal cruise ships and explore how many passengers they can hold.

Cruise ships have come a long way since their humble beginnings. From the pioneering ocean liners of the early 20th century to the state-of-the-art vessels of today, they have continuously evolved to create an exceptional cruising experience. From gourmet dining options and world-class entertainment to luxurious spas and thrilling onboard activities, cruise ships provide a myriad of amenities to keep passengers entertained throughout their voyage.

So, just how many passengers can these mammoth vessels accommodate? Well, the passenger capacity of a cruise ship can vary significantly based on several factors, including its size, layout, stateroom configurations, and onboard facilities. Larger ships tend to have a higher passenger capacity, as they have more space to accommodate various amenities and entertainment options.

When it comes to the largest cruise ship in the world, the title currently belongs to the awe-inspiring Symphony of the Seas, a part of Royal Caribbean’s Oasis Class of ships. This massive vessel can accommodate a staggering number of passengers, ensuring that there is never a shortage of excitement on board. Let’s take a closer look at the Symphony of the Seas and its extraordinary passenger capacity in the next section.

Overview of the world’s biggest cruise ships

In recent years, cruise lines have been engaged in a friendly competition to build the largest and most luxurious cruise ships in the world. These magnificent vessels boast multiple decks, elegant interiors, and an array of amenities that rival five-star resorts. Let’s take a brief look at some of the biggest cruise ships that have captured the imaginations of travelers worldwide.

• Symphony of the Seas: With a length of 1,188 feet and a weight of over 228,000 tons, Symphony of the Seas is currently the largest cruise ship in the world. This Royal Caribbean ship offers an incredible array of entertainment options, including 25 dining venues, 23 swimming pools, a zip line, a full-sized basketball court, and a casino.
• Oasis of the Seas: Another member of the Royal Caribbean’s Oasis Class, Oasis of the Seas measures approximately 1,187 feet in length and can carry over 6,000 passengers. This ship features Central Park, an open-air area with lush greenery, as well as an ice rink, a carousel, and a 1,380-seat theater.
• Allure of the Seas: Like its sister ship, Oasis of the Seas, Allure of the Seas is a part of Royal Caribbean’s Oasis Class. It measures about 1,187 feet and can accommodate over 6,000 passengers. Onboard, passengers can enjoy the thrilling zip line, numerous pools and hot tubs, Broadway-style shows, and a wide variety of dining options.
• Harmony of the Seas: Harmony of the Seas, also a member of the Oasis Class, spans approximately 1,188 feet and can hold more than 6,600 passengers. This ship offers innovative features such as the Ultimate Abyss, a 10-story slide, an AquaTheater for live performances, and a Central Park with over 12,000 live plants.
• MSC Meraviglia: MSC Meraviglia, operated by MSC Cruises, is one of the largest ships in the world, measuring around 1,034 feet in length. It can accommodate over 5,700 passengers and boasts an exclusive Mediterranean-style promenade, a water park, a full-size bowling alley, and a wide array of specialty restaurants.

These extraordinary cruise ships offer a multitude of lavish amenities and entertainment options, ensuring that passengers have a remarkable experience while sailing the seas. From world-class dining and thrilling water slides to Broadway-quality shows and luxurious spas, these mega-ships combine leisure and adventure to create unforgettable memories for travelers of all ages.

Now, let’s delve deeper into the factors that influence the passenger capacity of these colossal cruise ships.

Factors influencing the passenger capacity

The passenger capacity of a cruise ship is not solely determined by its size. Many factors come into play when calculating how many passengers a ship can hold. Let’s explore some of the key factors that influence the passenger capacity of these massive vessels.

Ship Size: Unsurprisingly, the size of a cruise ship plays a significant role in determining its passenger capacity. Larger ships have the advantage of having more space to accommodate various amenities and staterooms, allowing for a higher number of passengers on board. However, it’s important to strike a balance between size and maneuverability, ensuring that the ship can navigate different ports and waterways.

Layout and Design: The layout and design of a cruise ship also impact its passenger capacity. Ships with well-planned and efficient layouts can maximize the number of staterooms, public areas, and amenities, accommodating more passengers. Clever use of space and thoughtful architecture can help create a comfortable and spacious environment for travelers.

Stateroom Configurations: The types and sizes of staterooms available on a cruise ship can vary significantly. From compact interior cabins to expansive suites, there is a wide range of accommodations to cater to different budgets and preferences. The mix of staterooms affects the overall passenger capacity, as smaller rooms can accommodate more guests, while larger suites may have a lower occupancy limit.

Amenities and Facilities: Cruise ships are renowned for their extensive range of amenities and facilities. From restaurants and bars to pools and spas, these onboard features contribute to the overall passenger capacity. Additional dining venues, entertainment spaces, and recreational facilities can accommodate more passengers, ensuring that everyone has a variety of options to enjoy during their voyage.

Safety Regulations: Passenger safety is of utmost importance on cruise ships, and safety regulations can impact the maximum capacity of a vessel. Evacuation protocols, lifeboat capacity, and emergency exits are some of the factors that determine the maximum number of passengers a ship can carry safely in case of an emergency.

Crew-to-Passenger Ratio: The number of crew members onboard also affects the overall passenger capacity. Adequate staff is required to provide excellent service, maintain cleanliness, and ensure passenger safety. The size of the crew and their assigned duties must be taken into account when determining the maximum number of passengers a ship can accommodate.

By considering all these factors, cruise lines carefully design and construct their ships to optimize passenger capacity while maintaining the utmost safety and comfort for their guests.

Note: Widths shown are for the widest point for each ship. One T.E.U., or 20-foot equivalent unit, represents the volume of one 20-foot container, though ships can carry containers of varying sizes.

The container ship that hit the Francis Scott Key Bridge early Tuesday while leaving Baltimore Harbor is enormous. When fully loaded, the vessel, the Dali, can weigh more than 116,000 tons and carry thousands of containers of cargo.

But in comparison with some of the other ships out there, the Dali is a featherweight. The size of the largest container ships has grown, in fits and starts, since the early 1980s. The current largest class of container ships in the world can hold more than twice the amount of cargo that the Dali can.

Container Ships Keep Getting Bigger

Note: One T.E.U., or 20-foot equivalent unit, represents the volume of one 20-foot container, though ships can carry containers of varying sizes.

Giant ships have played a central role in the fueling of the modern economy, as global demand for electronics, clothes and other consumer goods continues to grow.

For shipping lines, the bigger the ship, the more cost efficient each voyage becomes.

The rise of massive ships has in turn pressured ports to adapt in order to attract business. For example, when an expansion of the Panama Canal in 2016 allowed larger ships to pass through, major Eastern Seaboard ports reacted by investing billions of dollars, said Jean-Paul Rodrigue, a professor in the department of maritime business administration at Texas A&M University-Galveston.

The ports, including Baltimore, scrambled “to dredge, to expand the infrastructure, to buy new cranes to accommodate these ships,” he said.

In August, the Ever Max, which is over 1,200 feet long and can hold up to 15,432 20-foot containers, became the largest container ship to ever enter the port of Baltimore.

Container ships are only one kind of common commercial vessel, however. Bulk ships and tankers have been on the bigger side for decades, and carry wet and dry goods that include oil and coal — a major export for the Baltimore port. In the 1970s, the decade that the Francis Scott Key Bridge was built, tankers roughly the same breadth and length as the Dali were in use in Eastern U.S. ports.

Bigger ships can create bigger disasters when accidents happen. Size played a role when a 1,300-foot vessel got stuck in the Suez Canal in 2021, causing alarming shipping delays.

The Dali’s size was not necessarily a factor in Tuesday’s accident, and investigators continue to search for sources of the cause. Even for a ship half the Dali’s size, Mr. Rodrigue said, “I suspect the outcome would’ve been the same.”

An earlier version of this article misstated the units of holding capacity for cargo ships. The capacity is measured in terms of TEUs, or 20-foot equivalent units, not containers.

What to know about the cargo ship Dali, a mid-sized ocean monster that took down a Baltimore bridge

Crews were set to begin removing the wreckage of a collapsed highway bridge in Baltimore on Friday. Maryland Gov. Wes Moore said a large crane, which can lift up to 1,000 tons, would be one of at least two used to clear the channel of the twisted metal and concrete remains of the Francis Scott Key Bridge, and the cargo ship that collided with it this week.

Investigators began collecting evidence Wednesday from the cargo ship that plowed into Baltimore’s Francis Scott Key Bridge and caused its collapse, while in the waters below divers searched through twisted metal for several construction workers who plunged into the harbor and were feared dead.

Here’s what to know about the cargo ship Dali that crashed into Baltimore’s Francis Scott Key Bridge, causing it to collapse and leaving six bridge construction workers presumed dead.

MONSTERS OF THE OCEAN

If stood upright, the Dali would reach almost to the top of the Eiffel Tower in Paris or about two-thirds of the way up the Empire State Building in New York.

It can carry the equivalent of almost 10,000 standard-sized metal shipping containers, and at the time of the accident was carrying nearly 4,700 containers. But while those figures are impressive, the Dali pales in comparison to the world’s largest container ships, which can carry more than 24,000 containers. There are environmental and economic advantages to operating giant container ships , but their sheer size and weight make them difficult to maneuver and stop — especially when something goes wrong.

Dali length: 984 feet (300 meters). Weight: 95,000 tons when empty.

Capacity: 10,000 20-foot (6-meter) containers.

MAYDAY CALL SAVES LIVES

The ship shares a name with one of history’s most celebrated artists, Spanish surrealist painter Salvador Dali.

Built by South Korea’s Hyundai Heavy Industries, one of the world’s largest shipbuilders, the Dali was launched in late 2014. It’s owned by Grace Ocean Private Ltd, flies a Singapore flag and is powered by diesel engines.

Danish shipping giant Maersk had chartered the Dali for a planned trip from Baltimore to Sri Lanka, but the ship didn’t get far, with the crew sending a mayday call early Tuesday saying they had lost power and had no control of the steering system. Minutes later, the ship rammed one of the bridge’s columns, causing the entire structure to collapse within seconds.

The ship was moving at about 8 knots, or 9 mph (15 kph). The mayday gave just enough time for authorities to stop bridge traffic and likely prevent more deaths , but not enough time to clear the construction crew that was filling potholes on the bridge. Divers on Wednesday recovered the bodies of two of the workers.

All of the nearly two dozen crew members from the Dali were accounted for after the accident, with one taken to a hospital with minor injuries.

PASSED PREVIOUS INSPECTIONS

The Dali passed a June 2023 inspection in Chile. A faulty pressure gauge for the fuel heaters was identified but fixed before the vessel left the port, according to authorities. The Dali was then inspected in September by the U.S. Coast Guard in New York, and no problems were found. Before it left Baltimore, the ship underwent routine engine maintenance, according to the Coast Guard.

Federal and state officials say the crash appears to be an accident.

The Coast Guard has downloaded the voyage data recorder and sent it to the National Transportation Safety Board, which is building a timeline of what led to the crash, and a preliminary report is expected in the coming weeks. Singapore also plans to carry out its own investigation, which it says will be to identify lessons for the future rather than determine liability.

WHAT’S NEXT

In addition to trying to clear the channel floor of the bridge debris, officials will need to assess the damage to the Dali and make sure it doesn’t leak fuel or sink. Investigators found damage to at least 13 containers on the ship.

The Dali will then likely be towed back to the port and the cargo offloaded.

Transportation Secretary Pete Buttigieg says it’s too early to say how long it will take to reopen the Port of Baltimore or replace the destroyed bridge. He noted it initially took five years to build the bridge .

Six presumed dead after cargo ship crash levels Baltimore bridge

BALTIMORE — A major Baltimore bridge collapsed like a house of cards early Tuesday after it was struck by a container ship, sending six people to their deaths in the dark waters below, and closing one of the country’s busiest ports.

By nightfall, the desperate search for six people who were working on the bridge and vanished when it fell apart had become a grim search for bodies.

“We do not believe that we’re going to find any of these individuals still alive,” Coast Guard Rear Admiral Shannon N. Gilreath said.

Jeffrey Pritzker, executive vice president of Brawner Builders, said earlier that one of his workers had survived. He did not release their names.

Up until then, Maryland Gov. Wes Moore had held out hope that the missing people might be found even as law enforcement warned that the frigid water and the fact that there had been no sign of them since 1:30 a.m. when the ship struck Francis Scott Key Bridge.

Moore expressed heartbreak after officials suspended the search for survivors.

"Our heart goes out to the families," he said. "I can’t imagine how painful today has been for these families, how painful these hours have been have been for these families."

It was a crushing blow to the loved ones of the missing men, who had waited for hours at a Royal Farms convenience store near the entrance of the bridge for word of their fate. 

Follow live updates on the Baltimore bridge collapse

The tragic chain of events began early Tuesday when the cargo ship Dali notified authorities that it had lost power and issued a mayday moments before the 984-foot vessel slammed into a bridge support at a speed of 8 knots, which is about 9 mph.

Moore declared a state of emergency while rescue crews using sonar detected at least five vehicles in the frigid 50-foot-deep water: three passenger cars, a cement truck and another vehicle of some kind. Authorities do not believe anyone was inside the vehicles.

Investigators quickly concluded that it was an accident and not an act of terrorism.

Ship was involved in another collision

Earlier, two people were rescued from the water, Baltimore Fire Chief James Wallace said. One was in good condition and refused treatment, he said. The other was seriously injured and was being treated in a trauma center.

Moore said other drivers might have been in the water had it not been for those who, upon hearing the mayday, blocked off the bridge and kept other vehicles from crossing.

“These people are heroes,” Moore said. “They saved lives.”

Nearly eight years ago, the Dali was involved in an accident. In July 2016, it struck a quay at the Port of Antwerp-Bruges in Belgium, damaging the quay.

The nautical commission investigated the accident, but the details of the inquiry were not immediately clear Tuesday.

The Dali is operated and managed by Synergy Group. In a statement, the company said that two port pilots were at the helm during Tuesday's crash and that all 22 crew members onboard were accounted for.

The Dali was chartered by the Danish shipping giant Maersk, which said it would have no choice but to send its ships to other nearby ports with the Port of Baltimore closed.

The bridge, which is about a mile and a half long and carries Interstate 695 over the Patapsco River southeast of Baltimore, was "fully up to code," Moore said.

National Transportation Safety Board Chairwoman Jennifer Homendy said that her agency will lead the investigation and that a data recorder on the ship could provide more information.

"But right now we're focusing on the people, on the families," she said. "The rest can wait."

President Joe Biden vowed to rebuild the bridge and send federal funds.

"This is going to take some time," the president warned. "The people of Baltimore can count on us though to stick with them, at every step of the way, till the port is reopened and the bridge is rebuilt."

Speaking in Baltimore, Transportation Secretary Pete Buttigieg echoed the president's promise.

"This is no ordinary bridge," he said. "This is one of the cathedrals of American infrastructure."

But Buttigieg warned that replacing the bridge and reopening the port will take time and money and that it could affect supply chains.

The Port of Baltimore, the 11th largest in the U.S., is the busiest port for car imports and exports, handling more than 750,000 vehicles in 2023 alone, according to data from the Maryland Port Administration.

Writer David Simon, a champion of Baltimore who set his TV crime drama "The Wire" on the streets of the city he once covered as a reporter, warned online that the people who will suffer the most are those whose livelihoods depend on the port.

"Thinking first of the people on the bridge," Simon posted on X . "But the mind wanders to a port city strangling. All the people who rely on ships in and out."

Timeline of crash

Dramatic video captured the moment at 1:28 a.m. Tuesday when the Dali struck a support and sent the bridge tumbling into the water. A livestream showed cars and trucks on the bridge just before the strike. The ship did not sink, and its lights remained on.

Investigators said in a timeline that the Dali's lights suddenly shut off four minutes earlier before they came back on and that then, at 1:25 a.m. dark black smoke began billowing from the ship's chimney.

A minute later, at 1:26 a.m., the ship appeared to turn. And in the minutes before it slammed into the support, the lights flickered again.

Maryland Transportation Secretary Paul Wiedefeld said the workers on the bridge were repairing concrete ducts when the ship crashed into the structure.

At least seven workers were pouring concrete to fix potholes on the roadway on the bridge directly above where the ship hit, said James Krutzfeldt, a foreman.

Earlier, the Coast Guard said it had received a report that a “motor vessel made impact with the bridge” and confirmed it was the Dali, a containership sailing under a Singaporean flag that was heading for Sri Lanka.

Bobby Haines, who lives in Dundalk in Baltimore County, said he felt the impact of the bridge collapse from his house nearby.

"I woke up at 1:30 this morning and my house shook, and I was freaking out," he said. "I thought it was an earthquake, and to find out it was a bridge is really, really scary."

Families of bridge workers wait for updates

Earlier in the day, relatives of the construction crew waited for updates on their loved ones.

Marian Del Carmen Castellon told Telemundo her husband, Miguel Luna, 49, was working on the bridge.

“They only tell us that we have to wait and that they can’t give us information,” she said.

Castellon said she was "devastated, devastated because our heart is broken, because we don’t know how they have been rescued yet. We are just waiting for the news."

Luna's co-worker Jesús Campos said he felt crushed, too.

“It hurts my heart to see what is happening. We are human beings, and they are my folks,” he said.

Campos told The Baltimore Banner that the missing men are from El Salvador, Guatemala, Honduras and Mexico.

Active search and rescue ends

The Coast Guard said it was suspending the active search-and-rescue effort at 7:30 p.m. Tuesday.

"Coast Guard’s not going away, none of our partners are going away, but we’re just going to transition into a different phase," Gilreath said at a news conference.

Maryland State Police Superintendent Roland L. Butler, Jr., said it was moving to a recovery operation. Changing conditions have made it dangerous for divers, he said. 

Butler pledged to "do our very best to recover those six missing people," but the conditions are difficult.

"If we look at how challenging it is at a simple motor vehicle crash to extract an individual, I'm sure we can all imagine how much harder it is to do it in inclement weather, when it's cold, under the water, with very limited to no visibility," he said.

"There's a tremendous amount of debris in the water," which can include sharp metal and other hazards, and that could take time, Butler said.

'A long road in front of us'

Built in 1977 and referred to locally as the Key Bridge, the structure was later named after the author of the American national anthem.

The bridge is more than 8,500 feet long, or 1.6 miles. Its main section spans 1,200 feet, and it was one of the longest continuous truss bridges in the world upon its completion, according to the National Steel Bridge Alliance .

About 31,000 vehicles a day use the bridge, which equals 11.3 million vehicles per year, according to the Maryland Transportation Authority.

The river and the Port of Baltimore are both key to the shipping industry on the East Coast, generating more than $3.3 billion a year and directly employing more than 15,000 people.

Asked what people in Baltimore can expect going forward, the state's transportation secretary said it is too early to tell.

"Obviously we reached out to a number of engineering companies, so obviously we have a long road in front of us," Wiedefeld said.
