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.”

World's largest cruise ship that's 5 times larger than the Titanic set to make its debut

By Li Cohen

July 12, 2023 / 8:38 AM EDT / CBS News

The RMS Titanic was once considered the largest ship in the world before it met its demise in the Atlantic Ocean. Now, Royal Caribbean International has created a "first-of-its-kind" ship nearly five times that size that will soon make its debut. 

The cruise ship, called Icon of the Seas, is massive – measuring 1,198 feet long with 250,800 gross tonnage. Capable of carrying 7,600 guests and 2,350 crew members, the ship is equipped with 20 total decks, seven pools, and what Royal Caribbean describes as six "record-breaking" waterslides.

When the RMS Titanic embarked on its ill-fated maiden voyage in 1912, it measured more than 852 feet long with 46,329 gross tonnage. Icon of the Seas' tonnage is more than five times that amount. 

The new ship will soon be ready for use, starting in January 2024, the cruise company says, after hitting a milestone last month with the successful completion of its i nitial round of sea trials . During those trials, the ship was put on the open ocean for the first time. 

The ship is divided into eight primary areas : 

• The "AquaDome" sits atop the front of the ship, offering 220-degree views and a 55-foot waterfall
• The "Suite Neighborhood" with a Mediterranean restaurant and two-floor sundeck
• A five-deck-high open-air "Central Park" with living plant walls
• "Chill Island" with four pools and a swim-up bar
• "Thrill Island," featuring what the company says is the largest waterpark at sea, called "Category 6"
• An area dedicated to families called "Surfside"
• The "Royal Promenade" with ocean views
• "The Hideaway," which offers 180-degree views at the back of the ship and an infinity pool

Icon of the Seas first opened up for reservations in October of last year while the cruise industry was still recovering from the downturn it faced during the coronavirus pandemic.  At the time, prices started at $1,537 a person, but they have since increased by a few hundred dollars. 

Royal Caribbean now lists the cheapest ticket at $1,851 for an interior room on a seven-night cruise from Miami to the Western Caribbean in September 2024. The most expensive is substantially higher – $10,864 for a suite on the same cruise in March. The ship also offers a seven-day trip to the Eastern Caribbean.

And while many are excited about the chance to ride the ship to the Caribbean, calling it "stunning" and like a "scene from sci-fi movie" on social media, some others have expressed otherwise. 

"Every time I see a picture of the Icon of the Seas cruise ship I am filled with an intense dread ," one person said. 

" Infection of the Seas by Royal Caribbean," another person jested, seemingly alluding to past COVID outbreaks on cruise ships during the pandemic. 

But for Royal Caribbean, it's all about the excitement. The day it opened up tickets for the ship in October, Royal Caribbean said it had the single largest booking day in the company's 53-year history.

"The enthusiasm and excitement for Icon are undeniable in more ways than one," Michael Bayley, president and CEO of Royal Caribbean International, said in October . "The incredible response we have received from our loyal guests, vacationers new to cruising, crew members and travel partners continues to come in, and this is just the beginning. We can't wait to share more of what Icon has in store in the coming months."

There's officially a new world's largest cruise ship

• The  Icon of the Seas officially joined Royal Caribbean 's 28-ship fleet on Monday.
• The 1,198-foot-long, 250,800 gross-ton vessel is now the world's largest cruise ship.
• This floating resort will begin operating cruises from Miami in late January 2024.

Say hello to the new world's largest cruise ship: The Icon of the Seas has officially joined Royal Caribbean's fleet of 28 cruise ships.

The cruise giant finally took delivery of its new 9,950-person Icon of the Seas from shipbuilder Meyer Turku shipyard during a ceremony on Monday. The behemoth vessel — a culmination of about two-and-a-half years of design and construction work — is scheduled to begin a series of cruises from Miami starting in late January 2024.

Related stories

At 20 decks, 1,198 feet long, and 250,800 gross tons, the Icon of the Seas towers over the average cruise ship. Onboard, travelers can expect some wild amenities with over 40 food and beverage venues, seven pools, a water park with six water slides, and a luxurious three-story stateroom for $75,000 a week. For the less wealthy travelers, the ship has another 2,804 guest cabins.

Despite having plenty of staterooms, vacations on this massive floating resort won't be cheap. The least expensive 2024 sailing starts at $1,820 per person for seven nights in an interior stateroom.

Royal Caribbean is in the business of building big ships. Before this new addition, its 1,188-foot-long, 235,600-gross-ton Wonder of the Seas has held onto the "world's largest cruise ship" title since its debut in 2022.

The cruise line has already begun construction on its next Icon-class ship: the Star of the Seas , sailing in the summer of 2025

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

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!

• Length: 1,130 ft / 344 m

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.

Celebration pays homage to her homeport of Miami with the 820 Biscayne zone, named after the cruise line’s first headquarters. The zone will feature the Deco Deli and 820 Bar , serving up Cuban sandwiches and tropical drinks.

Pizza fanatics will want to try the brand new Miami Slice , a free pizzeria that replaces the Pizza Pirate or Pizzeria del Capitano venues found on all other Carnival ships. The walk-up pizza joint features vibrant décor reminiscent of late-night eateries on Miami Beach’s Ocean Drive. 

Younger guests can check out Space Cruisers , a new program offered in partnership with the Kennedy Space Center. Kids age 2 to 11 will have the opportunity to try NASA-inspired activities tailored to their age group.

8. (tie) Costa Smeralda

Other eco-friendly features include LED lighting throughout the ship, an onboard desalinization plant that sustainably harvests onboard water directly from the sea, and systems that recover the engines’ heat to reduce energy use.

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 .

• Length: 1,184.42 ft / 361.011 m
• Staterooms: 2,759

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.

1 Icon of the Seas

One of the more exciting announcements from Royal Caribbean has been the creation of its largest ship ever: Icon of the Seas. This mega-ship boasts the title of largest in the world, as well as being a new flagship design from the brand. Royal Caribbean has always dominated the cruising sector, but with Icon of the Seas, they bring that title to a new extreme. The ship will have 20 decks, be 1,200 feet long, and weigh 250,800 gross tons. That makes it more of a mini city than a typical cruise liner, with Icon of the Seas breaking all records.

The 9 most exciting new cruise ships of 2023

This year will be a big one for new cruise ships, though not as big as last year.

Perhaps the most notable new cruise ship of 2023 will be MSC World Europa , the first of a new series of megaships from MSC Cruises that is designed to go head-to-head with Royal Caribbean 's giant Oasis-class ships.

It's just one of two major new cruise ships arriving in 2023 that has a tie-in to MSC Cruises. Also on the way is Explora 1, the first vessel for an all-new luxury line that is being developed by MSC Group, the parent company of MSC Cruises.

The year will also bring the first new ship in nearly a decade from upscale line Oceania Cruises , to be called Vista, as well as the first of a new class of ship for luxury line Silversea Cruises , to be called Silver Nova.

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

Those four vessels — MSC World Europa, Explora 1, Vista and Silver Nova — are the four new cruise ships for 2023 that have us the most excited here at TPG. However, they're not the only major new cruise vessels arriving during the next 12 months.

Also on the way are several significant new ships from major lines that, while new, will look familiar. That's because they will be sister ships to existing vessels. That is, while they will be new builds, they'll feature designs we have seen before.

Among lines unveiling new ships that are sisters to vessels already in their fleets are Norwegian Cruise Line , Carnival Cruise Line , Regent Seven Seas Cruises , Virgin Voyages and Celebrity Cruises .

Because a large percentage of the new cruise ships arriving in 2023 belong to an existing class and therefore have a familiar look, cruise fans might not find this year's new arrivals to be as exciting as last year's debuts.

The past 12 months, notably, saw the arrival of entirely new classes of vessels for Norwegian Cruise Line, Disney Cruise Line , Viking , Seabourn and Emerald Cruises, as well as an entirely new cruise brand ( The Ritz-Carlton Yacht Collection ). It was the sort of year that gets hearts racing for fans of new cruise ships.

Note that in some cases, the new ships coming in 2023 will arrive months behind schedule due to ongoing pandemic-related construction delays at the shipyards that are building them. Thanks to these delays, the first sailings of a few ships that were expected to debut in 2023 — including Royal Caribbean's much-awaited Icon of the Seas — have been pushed to 2024.

Icon of the Seas, which will be the biggest cruise ship in the world when it debuts, is now scheduled to sail with paying passengers for the first time in January 2024.

In all cases, the new ships that are on the way for 2023 are already available for booking — and are indeed booking up fast. Cruise fans always love to be on the latest and greatest vessels.

To whet your appetite for cruising in the year ahead, take a look at our list of the nine new cruise ships arriving in 2023 that have us the most excited.

MSC World Europa

Maiden voyage: Dec. 20, 2022.

Unveiled in the final days of 2022 (so close to year's end that we consider it a new vessel for 2023), this massive new MSC Cruises ship is nearly as big as Royal Caribbean's giant Oasis-class vessels — and that's a big deal.

This is the first time in the 13-year history of the record-breaking Oasis-class series (the world's biggest cruise ships) that a vessel has come close to the Royal Caribbean ships in size. MSC World Europa offers a major new option for cruisers who love being on the biggest, most amenity-packed vessels.

Additionally, it's just the first of at least four sister vessels that MSC Cruises plans to unveil over the next few years, including one destined for deployment in Florida .

In short, it kicks off a major new battle of the megaships.

At around 215,863 tons, MSC World Europa is about 4% to 8% smaller than the five Oasis-class ships. But by one measure, it's even bigger. MSC World Europa is 21 decks high — three decks higher than the Oasis-class vessels.

Like the Oasis-class ships, it's able to hold nearly 7,000 passengers with all berths filled — 6,762, to be exact.

As for its onboard offerings, MSC Cruises is taking a page from Royal Caribbean's playbook by breaking down the public areas of MSC World Europa into districts. They include an adults-only "Zen district" and a separate "family district" that houses as many as 10 new kids facilities. There also is a central interior promenade with entertainment, shops and bars.

Additionally, MSC World Europa has six pools and 14 hot tubs, making it one of the most pool-covered ships at sea. The watery offerings include an Aquapark with multiple waterslides that integrate virtual reality technology. There is also a family sun deck.

MSC World Europa has 13 dining venues, including the new-for-the-line Chef's Garden Kitchen (an outlet focused on microgreens) and La Pescaderia, a traditional seafood grill with alfresco seating. In a twist, the ship has three separate buffet restaurants as well, each with its own ambiance.

Drinking spots include a two-deck English-style pub dubbed Masters of the Sea Pub, which serves beer made on board. There's also a new gin bar, a first for MSC Cruises.

The line has a second new ship, the 4,810-passenger MSC Euribia, too, which will debut later in 2023 — in June, if all goes according to plan. At around 182,000 tons, it won't be quite as big as MSC World Europa but will still be one of the biggest cruise vessels in the world.

MSC World Europa is initially sailing in the Persian Gulf out of Dubai but will reposition to the Mediterranean for the summer of 2023. Fares for seven-night sailings start at $559 per person, not including taxes and fees.

Maiden voyage: May 13.

Upscale line Oceania Cruises is getting back into growth mode in 2023 with the unveiling of Vista — its first new vessel in more than a decade.

At 67,000 tons, Vista will be a tad bigger than Oceania's last two new ships, Marina and Riviera. However, it'll carry fewer passengers (1,200 versus 1,250), meaning its "space ratio" of space per passenger will be higher.

The space ratio of a ship is considered a measure of how upscale it is, with higher space ratios typically corresponding to more luxurious vessels.

As for decor and amenities, Oceania has promised an "evolution" of the intimate, residential-style interior venues for which its ships are known. Vista will retain such Oceania signatures as a Grand Staircase at its center and a Grand Lounge that serves as a central meeting point, as well as a martini bar, Aquamar Spa, Horizons observation lounge, a tranquil pool area and a casino with an accompanying bar.

Oceania also promises a wide range of cabin sizes for the ship, ranging from standard balcony cabins measuring 291 square feet (the largest standard balcony cabins in the industry, according to the line) to a range of super suites that measure from 1,000 square feet for an Oceania Suite to 2,400 square feet for an Owner's Suite.

Vista will also be the first Oceania vessel with built-from-scratch solo cabins — six in all. They'll measure 270 square feet and feature their own balconies, something that is relatively rare for solo cabins on ocean ships.

In fact, every cabin on Vista will be a balcony cabin, as every cabin has either a full balcony or a more limited French balcony. The ship will have no windowless inside cabins or balcony-less ocean-view cabins.

The solo cabins, notably, also are concierge-level cabins, which means they come with access to a private keycard-accessed concierge lounge and complimentary use of the ship's Spa Terrace.

Oceania long has been known as a foodie's line, and Vista won't disappoint, with 12 different culinary options for passengers — four of which will be new concepts for the brand.

The newcomers include Ember, serving "inventive American" cuisine, and wellness-focused Aquamar Kitchen (think: smoothies, organic "power bowls" and yellowfin tacos with white cabbage slaw). Also new will be the Culinary Center Dining Room, an ocean-view space offering food-and-wine pairing experiences that will tie to the ship's cooking classroom, and a new Bakery at Barista outlet that will serve fresh-baked pastries.

Classic Oceania eateries that will be on board the ship include the line's signature Polo Grill steakhouse, Italian-inspired Toscana and upscale Asian outlet Red Ginger.

Vista will be the first of two sister vessels in the line's new Allura class. The second ship in the series is scheduled to debut in 2025.

Vista will initially sail in Europe before repositioning to North America for the winter. Fares start at $1,699 per person, not including taxes and fees, for a seven-night Caribbean voyage out of Miami.

Resilient Lady

Maiden voyage: May 14.

Resilient Lady will be the third ship for Virgin Voyages, the startup line backed by Sir Richard Branson — and it'll look familiar to anyone who has sailed on the brand's first two vessels ( Scarlet Lady and Valiant Lady ).

Originally scheduled to debut in 2022 but delayed by nearly a year , the 2,770-passenger ship will be a nearly identical sister to the two earlier vessels, which began sailing in 2021 and 2022, respectively.

Like Scarlet Lady and Valiant Lady, Resilient Lady has been designed to shake up the cruise industry with a new, hipper style of cruising. The ship will have everything from a tattoo parlor to a colorful karaoke lounge where you can get your Lizzo on. To ensure a proper party vibe, it also will be a kid-free travel zone , with a minimum age to sail of 18.

Related: Is Virgin Voyages right for you? Our thoughts

Virgin is going after travelers who might think themselves too cool to cruise. To that end, Resilient Lady will have no buffets, no dress codes and no big Broadway-style theater shows. For entertainment, expect interactive dance parties, DJ sets and "microplays," plus late-night games of dodgeball. Suites will have a rock star theme .

A fourth vessel in the series, Brilliant Lady, is scheduled to debut in 2024.

Resilient Lady will initially sail in the Mediterranean before repositioning to Australia for the winter (where it'll mostly cater to the Australian market). Fares start at $455 per person for a two-night voyage out of Melbourne, Australia.

Maiden voyage: July 17.

Call it the biggest new cruise ship of 2023 — not in size, but in significance. The unveiling of Explora 1 will mark the arrival of Explora Journeys, an entirely new luxury line that could quickly become one of the biggest in the world.

A creation of the deep-pocketed MSC Group, which already owns MSC Cruises, Explora Journeys plans to launch at least six superluxurious vessels by 2028, each of which is designed to hold at least 922 passengers.

In just a few years, that'll give the line a bigger capacity than such well-known luxury cruise operators as Seabourn and the soon-to-relaunch Crystal Cruises .

Explora Journeys will compete in the same upscale cruise space as Seabourn and Crystal, as well as luxury lines like Viking, Silversea Cruises and The Ritz-Carlton Yacht Collection. It'll be run completely separately from its sister brand, MSC Cruises, which caters to a mass-market audience.

Like its five coming sisters, Explora 1 will offer oceanfront suites, penthouses and residences designed to be "homes at sea," and it'll be packed with upscale amenities. They will include 10 distinct culinary experiences, 10 indoor and outdoor bars and lounges, four swimming pools, outdoor deck areas with private cabanas, wellness facilities and entertainment.

MSC Group is the parent company of MSC Cruises and Explora Journeys, as well as the Mediterranean Shipping Company. The latter, also known simply as MSC, is the largest container shipping company in the world.

Explora 1 will initially sail in Northern Europe before repositioning to North America for the winter. Fares start at $3,600 per person, not including taxes and fees, for a three-night voyage from Hamburg, Germany, to Southampton, England.

Silver Nova

Maiden voyage: Aug. 14.

The latest ship for the luxury line Silversea Cruises will be bigger than its predecessors and feature an all-new design — one that, notably, will be asymmetrical in many areas. That is, some of the vessel's most prominent spaces, including its main pool area, will feature layouts that are off-center in a way that is unusual for cruise ships.

Silver Nova's main pool area, for instance, will have an unusual horseshoe shape with an orientation that runs from the port side of the ship to the starboard side. The pool itself will be off-center in the space, skewed far to the starboard side of the ship, with rows of lounge chairs and a grand entrance on its port side and unobstructed views through glass railings on its starboard side.

The idea is that the pool area will thus be much more orientated toward the destinations that the ship visits, or the open ocean when it is at sea, than the pool areas of other cruise vessels. Passengers will be able to float in the pool and look straight out over the water without the obstruction of more rows of lounge chairs.

Silver Nova's asymmetrical design will also be evident at two new food and beverage venues at the top of the vessel.

The first, Marquee, will be an alfresco dining venue that is also off-center, with an orientation that offers commanding views of the sea from the port side of the ship. It'll be home to The Grill, Silversea's signature outdoor "hot rocks" dining venue, and also double as the ship's Spaccanapoli pizza outlet. The second new venue, The Dusk Bar, will be an open-air sky bar at the back of the vessel that, like Marquee, is positioned on the port side of the ship.

Additional dining venues on board will include versions of Silversea's main signature restaurant La Terrazza, French eatery La Dame, seafood eatery Atlantide and sushi outlet Kaiseki.

In addition to asymmetry in many areas, one thing that will be particularly noticeable about Silver Nova is its spaciousness. At 54,700 tons, the ship will be about 34% bigger than the line's last three new vessels — Silver Muse, Silver Moon and Silver Dawn. It'll only hold about 22% more passengers, though. That means the space available per passenger will increase significantly.

With every berth filled, Silver Nova will sail with 728 passengers — just 132 more than the earlier vessels.

The extra space has allowed Silversea to expand its lineup of cabin categories on the ship, with more large suites. As is always the case with Silversea ships, every cabin on the ship will be a suite. However, Silversea fans will find new premium aft suites that include a massive 1,324-square-foot complex called the Otium Suite. Inspired by Silversea's new wellness program, Otium , the Otium Suite is in a premium aft corner position of the ship (according to the cruise line) and features floor-to-ceiling windows in all living areas. It has a sprawling 431-square-foot balcony area that is the most spacious on board.

Even the smallest cabins on Silver Nova will measure at least 357 square feet, which is unusually large for a cruise ship cabin.

Silver Nova will initially sail in the Mediterranean before repositioning to the Caribbean for the winter of 2023. Fares start at $4,700 per person, including a flight credit, airport transfers and shore excursions, for a seven-night Caribbean sailing out of Miami.

Norwegian Viva

Maiden voyage: Aug. 26.

The rollout of Norwegian Cruise Line's much-awaited Prima class of ships continues in 2023 with the arrival of Norwegian Viva — the second vessel in the series after the recently unveiled Norwegian Prima .

Like Norwegian Prima, Norwegian Viva is notably smaller than other vessels the line has added in recent years, such as the 3-year-old, 169,116-ton Norwegian Encore — a factor that will allow it to access smaller ports around the world. But, also like Norwegian Prima, Norwegian Viva will still pack a lot of over-the-top amenities, including a go-kart track that occupies three decks .

Plus, Norwegian Viva will have The Drop, a 10-story dry slide that Norwegian says offers more G-force than an accelerating Formula One race car. The vessel also will be home to a three-deck theater that converts into a Las Vegas-style nightclub and will host interactive, real-life game shows, including at-sea versions of "The Price Is Right."

Still, like Norwegian Prima, Norwegian Viva will be about more than flashy activities and entertainment. It'll also mark the continuation of a more upscale turn for the line that began with Norwegian Prima. Norwegian Viva will offer a wide range of suite categories (13), as well as the largest three-bedroom suites of any new cruise vessel. Inside Norwegian Viva, ocean view and balcony cabins also will be larger than has been typical for Norwegian ships in the past.

Additionally, Norwegian Viva will offer the most outdoor deck space of any new cruise ship, according to the line, including more total pool deck space than any other ship in the brand's fleet other than Norwegian Prima.

Norwegian Viva will initially sail in the Mediterranean before repositioning to the Caribbean for the winter of 2023. Fares start at $849 per person, not including taxes and fees, for a seven-night Caribbean sailing out of Miami.

Seven Seas Grandeur

Maiden voyage: Nov. 25.

Every few years, Regent Seven Seas Cruises comes out with a new ship so luxurious that it verges on the ridiculous — and that, in a nutshell, is what Seven Seas Grandeur will be.

A sister vessel to Regent's Seven Seas Explorer and Seven Seas Splendor (unveiled in 2015 and 2020, respectively), the 750-passenger ship will, like its sisters, be one of the most expensive cruise vessels ever built with all sorts of over-the-top luxuries.

Expect soaring ceilings, inlaid marble floors, crystal chandeliers and Picassos on the walls, for starters.

When it comes to cabins, Seven Seas Grandeur will basically offer two choices: fancy and really, really fancy. Every one of the ship's 375 rooms will be a suite. Even the smallest accommodations will measure 307 square feet, which is not too shabby for a cruise ship. Many cabins will be much bigger, though.

The biggest accommodation on board, the Regent Suite , will measure an astounding 4,443 square feet — nearly twice the square footage of the average American home. It'll cost $11,000 a night.

Seven Seas Grandeur will also offer an array of elegant and high-end restaurants, all of which are included in the fare.

This is what you would expect from Regent, of course. Known for its luxury focus, the 30-year-old brand has long operated some of the world's most elegant ships. Regent is the cruising equivalent of the hotel world's Four Seasons chain — a brand promising beautiful accommodations, refined food and pampering service.

After an initial transatlantic voyage from Barcelona to Miami, Seven Seas Grandeur will operate Caribbean sailings out of Miami for the winter before returning to Europe for the summer of 2024. Fares start at $4,439 per person, not including taxes and fees, for a seven-night Caribbean sailing out of Miami.

Celebrity Ascent

Maiden voyage: Dec. 3.

Celebrity Cruises will continue the rollout of its new Edge class of ships in 2023 with the unveiling of Celebrity Ascent — the fourth of five vessels in the series.

Like the last new Edge-class ship, the 8-month-old Celebrity Beyond , it'll be a stretched version of the two initial ships in the series ( Celebrity Edge and Celebrity Apex ), being both 20 meters longer and a deck taller.

As was the case with Celebrity Beyond, the extra length and height will allow for new and bigger venues, including an expanded "resort-within-a-resort" area for suite passengers called The Retreat and a greatly expanded Sunset Bar at the back of the vessel.

Like Celebrity Beyond, Celebrity Ascent also will offer a redesigned Rooftop Garden area with increased seating, new private nooks and two new floating pools cantilevered over the side of the ship.

Another area that will be bigger on Celebrity Ascent than on the first two Edge-class ships is the three-deck-high Grand Plaza.

As was the case with Celebrity Beyond, Ascent will have 179 more cabins than its sister vessels, each of which has 1,467 cabins. That's about a 12% increase. As a result, Celebrity Ascent, like Celebrity Beyond, will hold 3,260 passengers at double occupancy. That's up from a 2,910-passenger capacity at double occupancy for Celebrity Apex and a 2,918-passenger capacity at double occupancy for Celebrity Edge.

Celebrity Ascent initially will sail to the Caribbean out of Fort Lauderdale's Port Everglades. Fares start at $1,056 per person for a seven-night sailing.

Carnival Jubilee

Maiden voyage: Dec. 23.

Carnival Cruise Line will continue its move toward bigger ships in 2023 with the unveiling of Carnival Jubilee — the third vessel in its new Excel-class series.

Under construction at a shipyard in Germany, the 15-deck-high ship is a sister to the line's recently unveiled Mardi Gras and Carnival Celebration , which have made waves in the past 18 months for their huge size and what may be the most unusual attraction ever on a cruise vessel: a deck-top roller coaster .

Like Mardi Gras and Carnival Celebration, Carnival Jubilee will measure 181,808 tons, putting it in a tie with the former ships for the position of biggest ship ever to sail for Carnival. The two earlier vessels in the series are a whopping 35% bigger than the next-biggest Carnival ships currently afloat, and they are also bigger than all but 11 other cruise vessels in the world.

Also like Mardi Gras and Carnival Celebration, Carnival Jubilee will have a roller coaster on its top deck. Dubbed Bolt: Ultimate Sea Coaster, it'll be similar to the roller coasters on its sister vessels, with an 800-foot-long track and vehicles that reach speeds of 40 mph — give or take.

Carnival Jubilee will also be designed to hold up to 6,630 passengers. That's just a tad below the 7,084 passengers that can fit aboard Royal Caribbean's Wonder of the Seas — the world's largest cruise ship.

Carnival Jubilee will have a giant water park on its top deck and, like its sister, a far broader array of suites than earlier Carnival ships. However, the vessel won't be a carbon copy of the previous vessels. Carnival has said some new features are planned.

The development of ships on the scale of Carnival Jubilee and its sisters has been a big deal for Carnival. Until recently, the line had resisted the trend among major brands to build even-bigger vessels that offer a supersized megaresort-at-sea experience.

Carnival's last new vessel before the arrival of Mardi Gras in 2021, Carnival Panorama, didn't even crack the top 40 list of biggest ships when it debuted in 2019.

After an initial transatlantic voyage from Southampton, England, to Galveston, Texas, Carnival Jubilee will sail seven-night voyages to the Western Caribbean out of Galveston. Fares start at $549 per person, not including taxes and fees.

Other new ships

In addition to the above, newcomers for 2023 also include several small expedition ships and other small vessels from such cruise operators as Scenic Luxury Cruises & Tours, Seabourn, Emerald Cruises, Vantage Travel and Atlas Ocean Voyages.

Viking also has a new ocean ship coming in 2023 that is a sister to earlier vessels.

Endangered 44-foot whale likely killed by massive cruise ship, dragged into NYC port: experts

A massive cruise ship likely struck and killed an endangered whale before sailing into the East River Saturday morning — and there’s no telling how long the dead mammal was dragged by the boat before it was discovered, according to marine experts.

The 44-foot adult female Sei whale was found as the MSC Meraviglia docked at the Port of Brooklyn, a spokesperson for MSC cruises confirmed.

The unlucky cetacean was removed from the 19-deck ship and towed to Sandy Hook, New Jersey, Tuesday for a necropsy, said National Oceanic and Atmospheric Administration fisheries spokesperson Andrea Gomez — but emphasized it is too soon to tell whether or not the whale was dead before impact.

Rob DiGiovanni, the founder and chief scientist of the Atlantic Marine Conservation Society, however, told The Post it was more than likely that the “interaction with the vessel contributed to her death.”

“It looks like she was eating,” DiGiovanni said, indicating she was a healthy whale with relatively fresh food in her stomach.

The hulking Meraviglia — the same ship that rescued 24 distressed Cuban migrants from a boat off the coast of Florida last year — weighs 171,600 gross tonage and stands 214 feet tall.

When and where the whale was struck remains a mystery, but Sei whales are typically observed in deeper waters far from the coastline, according to NOAA.

They are one of the largest whale species and are internationally protected, with vessel strikes listed as one of the biggest threats to its dwindling population.

The body was “pretty decomposed,” DiGiovanni revealed, but said that does not help professionals lock down a timeline of its death.

The temperature of the water, especially on the higher side, can accelerate the decomposition process by days.

The tragic event is unfortunately not uncommon, according to DiGiovanni, but it’s nearly impossible to track just how often it occurs because the whales could sink to the bottom of the ocean floor after being struck.

Ship staff or guests also might not even notice a striking, considering just how large cruise vessels stand, making even the world’s largest mammal look like an ant.

Such strikes could contribute to the unusual mortuary event in the New York Bight Apex — the waters from Fire Island to the Manasquan Inlet in New Jersey.

Starting in 2016, humpback, Mackey and North Atlantic Right whale deaths skyrocketed from one to three per year to 12 to 14 per year, DiGiovanni said.

The shocking death surge is a tragic side effect of whales flocking to Big Apple waters in higher numbers per year, creating a Catch-22 situation.

While some stay year-round, the amount of whales enjoying the East River jumps as spring rolls around.

“We start to see increases in whale sightings now, so we urge boaters to use caution in the waters,” DiGiovanni said, encouraging ship captains to consider the “Slow: Children at Play” mentality when taking on the open seas.

NOAA reiterated this sentiment: “Mariners operating along the US East Coast are encouraged to slow their vessel speed, stay alert, and report any sightings of right whales or any dead, injured, or entangled whales.”

Cruise ship sails into New York with dead endangered whale across its bow

Examination underway to determine if 13-metre sei whale died before or after strike.

Social Sharing

A cruise ship sailed into a New York City port with a 13-metre dead whale across its bow, marine authorities said.

The whale, identified as an endangered sei whale, was caught on the ship's bow when it arrived at the Port of Brooklyn on Saturday, National Oceanic and Atmospheric Administration fisheries spokesperson Andrea Gomez said.

A video posted to YouTube on Saturday appears to show the whale's carcass hanging off the bow of the vessel, with the Statue of Liberty and the New York skyline in the background. 

A spokesperson for MSC Cruises said the whale was on the MSC Meraviglia, which docked at Brooklyn before sailing to ports in New England and Canada. The ship arrived in Saint John on Wednesday.

"We immediately notified the relevant authorities, who are now conducting an examination of the whale," officials with the cruise line said in a statement.

"We are deeply saddened by the loss of any marine life," the officials said, adding that the Geneva-based MSC Cruises follows all regulations designed to protect whales, such as altering itineraries in certain regions to avoid hitting the animals.

The dead whale was relocated to Sandy Hook, N.J., and towed to shore there to allow for better access to equipment and to conduct a necropsy, Gomez said.

A team from the Atlantic Marine Conservation Society conducted the necropsy on Tuesday. 

The examination determined the animal was a mature female and found evidence of tissue trauma along the area of its right shoulder blade, as well as a right flipper fracture, the organization said in a Facebook post on Wednesday.

Biologists will examine tissue and bone samples to determine whether it was already dead when it was struck by the ship, the post read.

Sei whales are typically observed in deeper waters far from the coastline, NOAA's Gomez said.

They are one of the largest whale species and are internationally protected.
