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!

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.

What is the largest cruise ship in the world?

Does 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, the ill-fated Titanic was the largest and grandest passenger vessel of its time. But, as of 2009, when Royal Caribbean debuted its first Oasis-class ship , the superlative applies to vessels more than five times Titanic's size.

So, what is the largest cruise ship in the world? At the time of publication, 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), it's a true behemoth. It boasts eight neighborhoods that feature everything from water slides, 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.

Cruise Ship Size Comparison: A Comprehensive Guide

by Judith Eve | Oct 30, 2023 | Cruise Planning & Cruiser Lifestyle

Cruise ship size is an important factor to consider when planning a cruise vacation. With so many different cruise ships available, it can be overwhelming to decide which one is right for you. This article will provide a comprehensive comparison of cruise ship sizes to help you make an informed decision.

Cruise ships come in a variety of sizes, from small vessels that can accommodate just a few hundred passengers to mega-ships that can hold over 6,000 people. The size of a cruise ship can impact the overall experience of your vacation, as larger ships may offer more amenities and entertainment options while smaller ships may provide a more intimate and personalized experience .

This article will compare cruise ship sizes in terms of length, weight (tonnage), height, and width/beam. It will also provide information on the passenger capacity, amenities, and destinations that each size of ship is best suited for. Whether you're a first-time cruiser or a seasoned traveler, this guide will help you choose the perfect cruise ship for your next vacation.

Understanding Cruise Ship Sizes

When it comes to choosing the right cruise ship, understanding the different sizes and their features is crucial. Cruise ships come in all shapes and sizes, from small luxury vessels to large resort-style ships. Here are some key factors to consider when it comes to understanding cruise ship sizes:

Gross Tonnage

One of the most important factors to consider when it comes to cruise ship sizes is gross tonnage. This refers to the overall volume of the ship, including all enclosed spaces. The higher the gross tonnage, the larger the ship. For example, the largest cruise ship in the world, Symphony of the Seas, has a gross tonnage of 228,081.

Length, Width, and Height

Another important factor to consider is the length, width, and height of the ship. The length overall (LOA) is the total length of the ship from bow to stern, while the beam is the width of the ship at its widest point. The height of the ship is also important, as it determines which ports the ship can access. For example, the Queen Mary 2, one of the largest ocean liners in the world, has a length of 1,132 feet, a beam of 135 feet, and a height of 236 feet.

Draft refers to the depth of the ship below the waterline. This is important because it determines which ports the ship can access. A ship with a shallow draft can access smaller ports and shallower waters, while a ship with a deep draft is limited to larger ports and deeper waters.

Passenger Capacity

Another important factor to consider is the passenger capacity of the ship. This refers to the number of passengers that the ship can accommodate. Smaller ships typically have a capacity of 500 passengers or less, while larger ships can accommodate up to 6,000 passengers or more.

Amenities and Onboard Features

Finally, it's important to consider the amenities and onboard features of the ship. Larger ships typically have more amenities, such as multiple restaurants, bars, and entertainment venues. Smaller ships may have fewer amenities, but they often offer a more intimate and personalized experience.

In conclusion, understanding cruise ship sizes is an important part of choosing the right cruise for your needs. By considering factors such as gross tonnage, length, height, draft, and passenger capacity, you can make an informed decision about which ship is right for you.

Largest Cruise Ships in the World

Cruise ships have been growing in size over the past few decades, with some of the latest vessels being the largest ever built. Here are some of the biggest cruise ships in the world:

These are just a few of the largest cruise ships in the world, with many more new vessels being built every year.

Cruise Ship Capacity

One of the most important factors to consider when choosing a cruise ship is its capacity. Cruise ship capacity is typically measured in terms of the number of passengers it can accommodate. This number can vary greatly depending on the size of the ship and the amenities it offers.

Passenger capacity is usually determined by the number of cabins, suites, and staterooms available on the ship. These accommodations can range from small, interior cabins to spacious, luxurious suites with balconies and private hot tubs.

Some cruise ships also offer additional amenities, such as restaurants, bars, theaters, and swimming pools, which can increase their passenger capacity. However, it's important to note that larger ships with more passengers may also mean longer lines and more crowded public spaces.

When choosing a cruise ship, it's important to consider your personal preferences and travel style. If you prefer a more intimate experience with fewer passengers, a smaller ship may be the way to go. On the other hand, if you enjoy a lively atmosphere with plenty of activities and entertainment, a larger ship may be more your style.

Overall, cruise ship capacity is an important factor to consider when planning your next cruise. By taking the time to research different ships and their passenger capacity, you can find the perfect cruise for your needs and preferences.

Cruise Line Comparisons

When it comes to choosing a cruise line, size is just one factor to consider. Each cruise line has its own unique personality, itinerary offerings, and onboard amenities. Here's a brief overview of some of the most popular cruise lines and how they compare in terms of ship size and other important factors:

Cruise Ship Costs

Cruise ship costs can vary greatly depending on a number of factors, including the size of the ship, the length of the cruise, and the amenities offered. Some cruises can cost as little as a few hundred dollars per person, while others can cost several thousand dollars per person.

When comparing cruise ship costs, it's important to consider the price on a per-day basis, as this can give a better idea of the overall value of the cruise. For example, a seven-day cruise that costs $1,000 per person may seem expensive at first glance, but when broken down to a cost of $143 per day, it may actually be a good deal.

In addition to the base cost of the cruise, there may be additional fees and expenses to consider. For example, some cruises may charge registration fees, which can add several hundred dollars to the overall cost of the cruise. It's important to read the fine print and understand all of the costs associated with a cruise before booking.

When looking for deals on cruise ship costs, it's important to do research and compare prices from different cruise lines. Some cruise lines may offer discounts for early booking or for booking multiple cruises at once. It's also a good idea to check with travel agents, as they may be able to offer special deals or packages.

Overall, while cruise ship costs can be expensive, there are ways to find good deals and get the most value for your money. By doing research and understanding all of the costs associated with a cruise, travelers can make informed decisions and enjoy a memorable cruise experience.

Onboard Amenities and Activities

Cruise ships offer a wide range of amenities and activities for their passengers to enjoy while at sea. Depending on the size of the ship, there may be more or fewer options available. Here are some of the most common onboard amenities and activities that can be found on cruise ships:

Restaurants and Bars

Overall, the amenities and activities offered on a cruise ship can vary depending on the size and type of ship. However, there is usually something for everyone, making a cruise a great option for those looking for a resort experience at sea.

Planning Your Cruise Vacation

Planning a cruise vacation can be an exciting and overwhelming experience. With so many options to choose from, it's important to consider your preferences and priorities to ensure you have the best experience possible.

When planning your cruise, consider the ports of call and itineraries offered by different cruise lines. Some cruises may focus on popular destinations, while others may offer more unique and off-the-beaten-path experiences. It's important to choose an itinerary that aligns with your interests and travel style.

Cruise ships come in a variety of sizes, from large mega-ships to smaller, more intimate vessels. Larger ships offer more amenities and activities, while smaller ships provide a more intimate feel and personalized service. Luxury cruises often rank higher in terms of service and amenities, but they come with a higher price tag.

It's important to keep safety rules and regulations in mind when planning your cruise vacation. All cruise ships must adhere to strict safety protocols to ensure the well-being of passengers and crew members. Additionally, it's important to research the safety record of the cruise line you're considering and read reviews from past passengers.

Overall, planning a cruise vacation requires careful consideration of your preferences and priorities. With the right research and preparation, you can ensure a memorable and enjoyable experience on the high seas.

Ship Specifics

When it comes to comparing cruise ships, there are several key factors to consider. One of the most important is the ship's length, which can impact everything from the number of passengers it can carry to the amenities it can offer. Another important factor is tonnage, which is a measure of the ship's size and weight.

The length of a cruise ship can vary widely, with some ships measuring less than 100 meters and others stretching more than 300 meters. Longer ships can typically accommodate more passengers and offer a wider range of amenities, while shorter ships may be better suited for more intimate voyages .

Tonnage is another important factor to consider when comparing cruise ships. This measurement takes into account the ship's size and weight, and can impact everything from the ship's stability in rough seas to its ability to offer a wide range of amenities. Larger ships typically have higher tonnage, while smaller ships may have a more intimate feel.

It's also worth noting that different cruise lines may have different standards for ship size and tonnage. For example, some luxury cruise lines may prioritize smaller, more intimate ships, while other lines may focus on larger, more amenity-rich vessels.

Overall, when comparing cruise ships, it's important to consider a range of factors beyond just size and tonnage. Other important considerations may include the ship's age, its onboard amenities, and the destinations it visits. By taking a comprehensive approach to ship comparison, travelers can find the vessel that best suits their individual needs and preferences.

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
• Max. passengers: 5,655

When MSC’s Meraviglia entered service in 2017, she was the sixth-largest cruise ship in the world—but has since fallen to #15, tied with her newer sister ship Bellissima .

The namesake of the Meraviglia class of cruise ships, she was the first to offer an expanded dining experience with fourteen restaurants, including a whopping four complimentary main dining rooms. Celebrity chef Carlo Cracco was enlisted to improve the quality of the ship’s cuisine.

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.

14. (tie) MSC Virtuosa

• Year built: 2020
• Gross tonnage: 181,541
• Length: 1,087.4 ft / 331.43 m
• Max. beam: 160 ft / 50 m
• Staterooms: 2,421
• Max. passengers: 6,334

MSC’s ship Virtuosa , built in 2020, is one of the newer offerings by the Swiss-Italian cruise line and is tied for number fourteen on our list of the world’s biggest cruise ships.

Virtuosa offers five pools in total, plus a water park with three waterslides, so water babies of all ages can spread out and enjoy the fun. The pools can accommodate over a thousand guests at a time!

If relaxing with a cocktail is more your style, stop by and see Rob the bartender at Starship Club . He’s the first humanoid bartender at sea, and speaks six languages!

Cruisers can also wander the Galleria Virtuosa —the pretty indoor promenade with restaurants and shops features an arched ceiling with the longest LED dome at sea , presenting an ever-changing light display.

14. (tie) MSC Grandiosa

• Staterooms: 2,632
• Max. passengers: 6,761

Tied for number 14, Grandiosa was the first vessel in MSC’s Meraviglia-Plus class , later joined by her sister ship MSC Virtuosa .

With 200 more staterooms than previous MSC ships, Grandiosa has expanded the number of accessible cabins on board, and added groups of up to three connecting staterooms as well as new family balcony cabins. Some spacious family staterooms can sleep up to twelve!

Grandiosa also has some innovative environmental features, including systems to reduce nitrogen oxide emissions by 80%, and sulfur emissions by 97%. She has a fuel-efficient hull and can run on shore power when docked.

Fun fact: Grandiosa ‘s godmother is Italian screen legend and longtime MSC ambassador Sophia Loren. She actually holds that honor for most of MSC’s fleet!

13. Mardi Gras

• Cruise line: Carnival
• Gross tonnage: 181,808
• Length: 1,130 ft / 344 m
• Max. beam: 138 ft / 42 m
• Staterooms: 2,641
• Max. passengers: 6,630

The 13th biggest cruise ship in the world is Carnival Cruise Line’s widely-anticipated Mardi Gras (currently the cruise line’s second-largest ship) which took her maiden voyage in July 2021.

Mardi Gras debuted several new concepts for Carnival, including three new dining venues. Big Chicken by Shaq serves up fried chicken and more, while quick-service Street Eats offers three food stations, each specializing in a different type of cuisine.

Emeril’s Bistro 1396 , created in partnership with celebrity chef Emeril Lagasse (Carnival’s new Chief Culinary Officer ), serves up New Orleans-style Creole dishes.

The Grand Central Atrium reinvented the central area of the ship, with a larger space featuring bars, cafés, and shops with aerial performances overhead.

She also boasts the first rollercoaster at sea —BOLT is an open-air coaster with spectacular sea views. Riders can control their speed using pedals inside each two-person motorcycle-themed car.

12. AIDAcosma

• Cruise line: AIDA
• Year built: 2021
• Gross tonnage: 183,200
• Length: 1,106 ft / 337 m

The Geneva-based company has been working diligently to expand the fleet and MSC’s newest cruise ship is a whopper of a vessel.

The ship is an astounding 21 decks high (there’s a deck 22, but cruise superstition skips deck 13), four decks taller than the largest cruise ship in 2023. Sixteen of those decks are passenger-accessible.

Much like the megaships offered by Royal Caribbean, MSC World Europa is divided into several districts that contain similar offerings—a must-have on any gargantuan cruise ship. Guests can visit the adults-only Zen district for a bit of calm, or the Family district with ten kids’ facilities offering fun for little cruisers and their grownups.

Ranking among the top ships with the most water features at sea, World Europa offers six pools and 14 hot tubs , along with an aquapark featuring multiple waterslides.

Oasis of the Seas may be an older ship, but she doesn’t look like one! In 2019 she had a $165 million transformation that brought the ship up to date.

Entertainment abounds on this ship, from the splashy Aqua80 show in the AquaTheater to Music Hall , a live music venue with plenty of floor space for dancing. Or try one of the four onboard water slides including the ten-story-high Ultimate Abyss .

3. Harmony of the Seas

• Year built: 2016

• Length: 1,184.42 ft / 361.011 m
• Staterooms: 2,759
• Max. passengers: 6,680

The largest cruise ship in the world until 2022, Symphony of the Seas comes in second—but is still a behemoth at 1184 feet and 228,081 gross tons!

Built in 2018, Symphony of the Seas boasts some fun tech! Check out the Big Wonder , a seven-ton canopy lit with color-changing LEDs that cast a glow over the ship’s Solarium at night.

Enjoy a cocktail at Bionic Bar , where one of two robot bartenders can shake you up the perfect martini. But don’t worry, the ship’s 13 other bars and lounges are staffed by friendly humans.

Or play a lively game of glow-in-the-dark laser tag to battle for control of Planet Z —when the ship’s ice rink is temporarily transformed into an alien world, of course.

Wonder of the Seas offers some exciting new features—in addition to boasting the largest poolside movie screen of any RCCL ship there’s also The Vue , a cantilevered bar offering panoramic ocean views.

For the kids, there’s the new Wonder Playscape —an underwater-themed play area with climbing walls and an interactive puzzle mural.

The World’s Largest Cruise Ship Is Nearly 1,200 Feet Long

Scheduled to debut in January, the vessel can accommodate 5,600 guests and 2,350 crew members

Daily Correspondent

The world’s largest cruise ship is almost ready to set sail.

Royal Caribbean’s massive new ship, Icon of the Seas , passed its inaugural round of sea trials with flying colors, bringing it one step closer to hitting the open ocean with passengers, the cruise line  announced late last month. If all goes as planned, the record-breaking vessel will begin sailing in the Caribbean in January 2024.

Just how big is Icon of the Seas ? Really big. As Jalopnik ’s Ryan Erik King writes, it’s the size of five Titantics. More specifically, Icon of the Seas measures 1,198 feet long—nearly a quarter of a mile—and has a gross tonnage of 250,800. All that space means it can accommodate 5,600 guests and 2,350 crew members.

The cruise line is positioning the vessel as “the ultimate family vacation,” as CEO Michael Bayley told reporters earlier this year, per  CNN ’s Maureen O’Hare.

“When you step back and look at all the energy and time that has gone into creating this ship, it is mind-blowing,” he added.

The previous world’s largest cruise ship was also a Royal Caribbean vessel, Wonder of the Seas , which spanned 1,188 feet long and featured 18 decks.

Crews in Turku, Finland, began work on Icon of the Seas in 2021. Last month, the vessel sailed the open ocean for the first time, as staffers spent four days testing the main engines, hull, brakes, steering system and other components. They also measured noise and vibration levels. 

The vessel will undergo another round of sea trials later this year before officially launching in Miami early next year, according to Royal Caribbean. Icon of the Seas will primarily take cruisers to the islands of the eastern and western Caribbean on seven-night itineraries.

With progress on Icon of the Seas moving along, Royal Caribbean has already started building another large “icon class” ship. The cruise line expects that unnamed vessel to launch in 2025, per a  statement .

Icon of the Seas has 20 total decks, 7 swimming pools and 8 “neighborhoods,” or distinct areas with entertainment and dining. Another noteworthy feature is Category 6, which will be the largest waterpark at sea when Icon of the Seas sets sail.

The ship will be equipped with a special grooming robot that will clean the hull whenever it’s in port to help reduce drag and improve fuel efficiency by 3 to 4 percent, reports  TTG Media ’s Charlotte Cullinan.

Icon of the Seas will also be the first ship in the cruise line’s fleet to run on liquefied natural gas and  fuel cells , which are similar to batteries but do not need to be recharged. Water is the main byproduct of fuel cells—which combine oxygen and hydrogen to produce energy—which should help the ship reduce its greenhouse gas emissions.

Liquefied natural gas , meanwhile, is a controversial energy source that involves cooling natural gas to a liquid state to make it easier to transport. The liquid version is “actually worse than ordinary gas,” writes the  Natural Resources Defense Council . “The energy required to chill, ship and regasify the fossil fuel makes it far more carbon-intensive and increases the potential for leakage of dangerous methane,” according to the organization.

Royal Caribbean’s leaders say they view liquified natural gas as a “ transitional fue l,” and that they hope to continue to  reduce the environmental impact of their ships moving forward. 

"[Liquefied natural gas] is about 20-30 percent better for the environment [than heavy fuel oil], but it’s still not going to be the solution,” Bayley tells TTG Media . “We don’t know the answer, but the whole industry is working towards the answer.”

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.

At a glance

The Icon of the Seas:

• can carry up to 7,600 passengers and 2,350 crew members

The ship has:

• six waterslides
• seven swimming pools
• an ice-skating rink
• more than 40 restaurants, bars and lounges

“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.”

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

By Kris Van Cleave , Analisa Novak

January 18, 2024 / 12:14 PM EST / CBS News

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.

21 Facts About The World's Biggest Cruise Ship You Won't BELIEVE

Posted: June 7, 2024 | Last updated: June 7, 2024

Onboard the world's largest cruise ship

Royal Caribbean's latest marvel,  Icon of the Seas , set sail on its maiden voyage in January. The mammoth vessel currently holds the record as the world's largest cruise ship and has captured the imagination due not only to its sheer size but also its outrageous opulence.

Read on to explore the staggering numbers behind the super-sized ship and discover the fantastic facilities passengers enjoy. 

All dollar amounts in US dollars. 

The size, scale, and staggering cost

Construction on Icon of the Seas began in 2021 at the Meyer Turku shipyard in Finland.

The juggernaut vessel is almost 1,200 feet long and weighs a staggering 250,800 gross tons, surpassing the measurements of all other cruise ships to date. To put that into some kind of perspective,  Icon is around five times larger than the Titanic .

Unsurprisingly, its construction price tag was a dizzying $2 billion.

Incredible capacity of 9,950

Icon is effectively a floating town and can accommodate close to 10,000 people when at maximum capacity, including 7,600 guests and a dedicated crew of 2,350.

Its diverse team of workers hail from 80 different countries around the world, including the United States, United Kingdom, the Philippines, Jamaica, and Australia. Their roles range from hospitality and performing arts to gardening and maintenance, with the overarching goal of ensuring a seamless experience for guests at all times. 

Breaking booking records

In October 2023, tickets went on sale for seven-day voyages to the Caribbean aboard the boat, with prices starting at around $1,537 per person.

The sales resulted in Royal Caribbean achieving its "single largest booking day in the company's 53-year history," neatly underscoring the excitement surrounding this gigantic new cruise ship.

Room prices start at $1,851

While room prices have since increased for week-long voyages, you don't need to be super-rich to board this super-sized ship. Icon offers 28 different room types, giving guests options to suit all needs, whether they're looking for affordability, stunning sea views, or a family-oriented vacation experience.

According to  Forbes , interior rooms now range between $1,851 and $3,300, while exterior rooms span from $2,061 to $4,119. Balcony rooms, which offer a more premium guest experience, start at $2,249 and can reach up to $5,245.

Meanwhile, luxury Sunset Suites (pictured) cost a staggering $10,864 per week per person for those looking to splurge. Costs vary depending on the time of the year, with March to September the peak time to travel. 

The most expensive suite costs $75,000

The most expensive accommodation is the all-new Ultimate Family Townhouse (pictured). The spacious pad, which can accommodate eight guests, spans 2,523 square feet across three levels.

Perfect for families with young kids to entertain, it features a multilevel slide, a movie and karaoke area, two private balconies, a whirlpool, and an outdoor dining area.

However, renting out this fun-filled suite for one week is far from cheap and will cost you an eye-watering $75,000, according to  Business Insider.

20 fun-filled decks

Icon boasts 20 decks brimming over with activities and attractions to keep guests entertained. 

Highlights include an adrenaline-pumping surf simulator, a rock climbing wall that offers stunning sea views, a family-friendly mini-golf course, laser tag, arcades, a sports court, a luxurious casino, and a water park.

Eight unique neighborhoods

Across the 20 decks, the ship is divided into eight unique "neighborhoods," each offering guests a different experience. Let's delve into each neighborhood and their standout features...

First up, the Thrill Island neighborhood, spanning decks 16 and 17, is designed for daredevils. It includes a pulse-racing waterpark (more on that soon) and Crown's Edge (pictured), a heart-pounding ride that allows brave passengers to swing 154 feet above the ocean.

Surfside neighborhood

The colorful Surfside neighborhood (pictured) is the ultimate hotspot for families.

Located on deck seven, activities include swimming areas appropriate for both babies and children, as well as a charming beach-themed carousel, arcades, and family-friendly events and eateries.

The Hideaway

The Hideaway neighborhood, situated on deck 15, is a designated adult-only area and offers guests an exclusive beach club vibe. 

It features the first-ever suspended infinity pool at sea (just one of the record-breaking pools aboard the ship, but more on that soon), a dedicated bar, and a DJ.

Central Park

The open-air Central Park neighborhood, located on deck eight, is packed with restaurants and nightlife, including numerous live music spots and trendy jazz bars.

But the most impressive feature of this lush area is the four living plant walls, boasting more than 30,550 plants in total.

Chill Island

The sprawling Chill Island neighborhood spans decks 15, 16, and 17 and is filled with spots where guests can sit back and bask in the sunshine, complete with breathtaking ocean views.

Stand-out features include the Royal Bay, which, at 5,813 square feet, is the largest pool at sea, and Swim & Tonic, Royal Caribbean's first-ever swim-up bar at sea.

The AquaDome

The most visually jaw-dropping neighborhood is arguably the AquaDome, located on decks 14 and 15. This section of the ship boasts wraparound ocean views and features a show-stopping 55-foot-tall waterfall. 

AquaDome is also home to Royal Caribbean's first food hall and provides guests with the opportunity to watch fantastic water shows at the AquaTheater.

Royal Promenade

Located on decks five and six, the Royal Promenade neighborhood is the first to feature floor-to-ceiling ocean views.

The area is positively buzzing with bars and restaurants, but its most impressive feature is Absolute Zero, the largest ice arena at sea. Here, guests can watch dazzling live performances or take to the ice themselves. 

The Suite neighborhood

Last but by no means least, the Suite neighborhood is reserved purely for passengers staying in the Royal Suite Class. Spanning decks 16 to 19, it offers high-paying guests an additional slice of luxury during their time aboard.

The area is equipped with a multi-level sun deck with its own pool and whirlpool, while the VIP guests can enjoy a range of exclusive bars and dining options.

40 bars, restaurants, and lounges

Neighborhoods aside, the cruise ship caters to all appetites, with more than 40 bars, restaurants, and lounges to choose from.

Among them are the likes of Pier 7, which offers beachside brunches; Giovanni’s Italian Kitchen & Wine Bar, serving up classic Italian-style favorites; and SurfSide Bites, which provides family-friendly options like hotdogs and popcorn chicken.

One truly wow-worthy dining spot is the opulent Empire Supper Club (pictured), where guests can devour dishes such as oysters and Wagyu beef with shaved truffle while sipping on premium cocktails and enjoying live jazz.

50 entertainers aboard

Icon sails with a cast of 50 musicians, actors, and comedians who keep passengers entertained with live shows.

Among the entertainment headline acts is a 16-piece orchestra and the first-ever at-sea performance of  The Wizard of Oz .

Seven incredible swimming pools

Icon boasts seven different pools, each designed with its own unique vibe. As mentioned,  Icon  is home to the Royal Bay (pictured), which is currently the largest pool at sea. There's also the Hideaway Pool, the first-ever suspended infinity pool at sea, and Swim and Tonic, the first-ever swim-up bar at sea. So what about the incredible pools we haven't covered yet?

The Water's Edge Pool is a family-friendly swim spot, Cloud 17 offers a super-chilled atmosphere, while Cove Pool is located portside, providing stunning views. And finally, there's The Grove, located in the Suite Neighborhood, which is exclusive to Royal Suite Class guests.

In addition to the seven swimming pools, guests also have access to nine whirlpools. 

Six record-breaking slides

A key attraction aboard Icon is the Category 6 waterpark. With six record-breaking waterslides (pictured), it's – you guessed it – the largest at sea.

The adrenaline-pumping Frightening Bolt is the tallest slide at sea at 46 feet tall, while the daring Pressure Drop is the first freefall waterslide to set sail. What's more, the waterpark features two family raft slides, as well as two exhilarating mat racer slides.

The Wonder of the Seas

Prior to the launch of  Icon of the Seas , Royal Caribbean's fleet already boasted the world's largest cruise ship.

Wonder of the Seas (pictured) first set sail in 2022 and is only fractionally shorter than Icon . It can carry a total of 7,084 guests, with an international crew of 2,204 people. The vessel boasts 18 decks, just two fewer than its larger (yet younger) sister.

Environmental credentials

Royal Caribbean claims Icon  is 24% more energy efficient than required standards, making it the company's most sustainable ship yet. It's powered by liquefied natural gas (LNG), and the dual-fuel engines work alongside various energy efficiency initiatives and industry-leading environmental programs, such as the first waste-to-energy system at sea.

The ship also produces 93% of its fresh water onboard via a reverse osmosis/desalination plant and is landfill-free. The company has plans to introduce a net-zero cruise ship by 2035.

A negative impact?

However, critics have argued that using LNG as fuel contributes to emissions of methane, a harmful greenhouse gas.

Bryan Comer, director of the International Council on Clean Transportation’s marine program, told The Guardian : "[Royal Caribbean] is doubling down by calling LNG a green fuel when the engine is emitting 70 to 80% more greenhouse gas emissions per trip than if it used regular marine fuel. Icon has the largest LNG tanks ever installed in a ship. It is greenwashing.”

10 largest cruise ships in the world and who owns them

When my kids were young, I loved mega-ship cruise vacations. Our family booked yearly cruises trying different lines and ships. I'd make one phone call and one payment, and the vacation was set. 

While perfect at the time, I slowly began to feel "cruise-ship fatigue."  

I was tired of fighting for lounge chairs, standing in buffet lines, and dealing with the crowds. The smoky casinos, hypnotists, and piano players pounding out "Sweet Caroline" no longer appealed. 

Once our kids left for college, my husband and I felt we'd outgrown mega ships . 

So when we started researching a trip to celebrate our anniversary, I proposed a small-ship experience . I'd heard friends talk about the joys of small-ship sailing, and we could finally afford it. 

We had paid as little as $100 a day on mega-ship cruises. For smaller ships, you pay closer to $600 a day per person. A special anniversary was my excuse to splurge. 

I was drawn to Windstar's Wind Spirit : a 140-passenger sailing yacht that would be an easy sell to my sailor husband. We chose a seven-day trip through Tahiti, the South Polynesian Islands, and Bora Bora. The cruise cost $4,299, or about $614 a day per person. 

We traveled on the Windstar this March. Here are the pros and cons of choosing a small-ship experience.

The staff-to-passenger ratio meant the service was incredible

We shared our small ship — which felt more like a rich friend's yacht — with only 100 other passengers.

With 100 staff on board, that meant incredibly personalized service and intimate day trips. 

One day, six of us visited a private island. We were greeted by waiting crew members with flower garlands, tropical beverages, and beach towels. 

When I ordered a coconut-rum and coke from the tiki bar they'd set up, the bartender realized he didn't have that specific liquor. Before I could offer my second choice, he called the ship, reported that one of the passengers would like some coconut rum,  hung up, and smiled. "They will motor it over from the ship," he said. "I'll deliver your drink to you when it arrives."

It felt like your every whim would be catered to. 

We could access destinations that aren't open to mega ships and visit without crowds 

Large ships aren't allowed near some of the islands we traveled to for environmental and logistical reasons. 

Because the Wind Spirit didn't require large docking furniture or canals necessary for larger ships, we easily sailed into coves and dropped anchor.

Every time we emerged onto the deck, we were met with scenery like Moorea's green mountains dropping into the blue water or traditional huts tucked into palm-tree alcoves. These views were never blocked by crowded railings. 

The islands we visited were also nearly empty of tourists. There were no more than eight people in our group on all the excursions we booked .  

I was happy to avoid the massive cruise ships carrying thousands of passengers disembarking at the same time and being frog-marched to the same attractions.

Each island felt private; each excursion could be tailored to our wishes. 

The entertainment on board is very pared back and simple 

You won't get Broadway-style entertainment on a small ship. You won't have casinos, rows of shops, or waterslides. 

The experience is closer to yachting, where you soak in the destination rather than follow an activity-packed itinerary. 

We could visit the bridge and talk to the captain, join a mixology class, or sit with local islanders and make traditional crafts. As Calvin Dsouza, a hotel general manager at Windstar Cruises, told me, "This is an opportunity to connect to the actual place, rather than seeking your next thrill."

The boat's water-sports marina, only open when the ship was anchored, was on the deck one floor down from our cabin. Surrounded by beautiful scenery, we jumped off the swim deck,  floated on a tethered platform or trampoline, or grabbed a kayak or paddle board.

It felt surreal to swim straight off the boat into the Pacific Ocean. Occasionally, others joined in, but many times, it was just us.

Feeling like the ship and the destination were ours to explore was my favorite aspect of small-ship cruising.

I was tired of cruise food, but the gourmet small-ship options changed my mind

The food on board was a close-second favorite. I had pretty much sworn off cruises because of the food: eggs that never quite tasted like eggs, slight variations of the same dishes at multiple meals, and menus shaped around how many they could feed rather than creativity. 

The dining experience on a small ship was the opposite. Windstar partners with James Beard and features award-winning cuisine on its nightly menu. 

The food on board far exceeded my expectations. We enjoyed fresh bread out of the oven,  a whole suckling pig, lobster tails, paella, and perfectly cooked steaks. I was delighted by every meal. 

One of my favorite dining experiences was in Bora Bora. We arrived at a private island with views of Mount Otemanu and were served fresh red snapper and generously poured top-shelf drinks, all while chatting with fellow passengers who had become friends. 

It's worth the price if you can entertain yourself

My takeaway is, if you don't need 100 activities on board, small-ship cruising is for you. Small ships don't entertain you all day long — you find and make your entertainment.

The Wind Spirit is more expensive upfront than your average mega ship, but it's worth every penny, and I'll be booking a small-ship cruise vacation again.
