▷ Facts & History

Cruise ships are true engineering marvels, towering taller than many iconic landmarks and generating enough power to rival a small city. These floating resorts are equipped with advanced desalination systems to produce their own fresh water, and their vast food supply could easily feed a small town. Behind the scenes, a diverse and multicultural crew operates the ship like a self-contained city, managing everything from entertainment and hospitality to navigation and safety. Their sheer scale, complexity, and self-sufficiency make them one of the most impressive feats of modern maritime design.
Cruise ships use discreet emergency codes to alert crew members without alarming passengers, ensuring swift and coordinated responses. For example, “Alpha, Alpha, Alpha” signals a medical emergency on Royal Caribbean and Norwegian ships, while “Alpha Team, Alpha Team, Alpha Team” indicates a fire emergency on Carnival Cruise Line vessels. The universal abandon ship signal consists of seven short blasts followed by one long blast on the ship’s horn and internal alarm system. Other common codes include “Bravo” for fire, “Oscar” for man overboard, “Delta” for ship damage, “Echo” for navigational emergencies, and “Code Red” for outbreaks like norovirus. These standardized codes are essential for maintaining safety and order during critical situations at sea.

On cruise ships, an upside-down pineapple displayed on a cabin door, clothing, or accessories is widely recognized as a discreet symbol used by some couples to signal interest in swinging or partner swapping. While pineapples traditionally represent hospitality, flipping the fruit upside down has taken on a more provocative meaning within the “lifestyle” community. This subtle code allows like-minded individuals to identify each other without drawing attention, and it’s often seen in the form of door magnets, pins, or pineapple-themed apparel. Though not officially endorsed by cruise lines, the symbol has become a quiet fixture in certain adult-oriented cruise circles.
Over the past century, approximately 24 full-size cruise ships and ocean liners have sunk. While these incidents are rare compared to the millions of safe voyages completed each year, they can be significant due to the large number of passengers and crew involved. Many of the sinkings occurred in the first half of the 20th century, often under wartime conditions or during scrapping operations, and only a few involved active passenger service. Notable examples include the Titanic (1912), Empress of Ireland (1914), and the more recent Costa Concordia (2012), which sank off the coast of Italy due to navigational error. Advances in ship design, safety regulations, and crew training have dramatically reduced the likelihood of such disasters in modern times.

RMS Titanic, RMS Queen Mary, SS Normandie, SS United States, SS Andrea Doria, and RMS Lusitania are some of the most famous ocean liners that have fascinating histories, filled with triumphs, tragedies, and legendary voyages; each of these ships played a role in shaping maritime history.

RMS Titanic - Perhaps the most well-known ocean liner, the Titanic sank on its maiden voyage in 1912 after hitting an iceberg. Despite being advertised as "unsinkable," the disaster claimed over 1,500 lives and led to major changes in maritime safety.
RMS Queen Mary - Launched in 1936, the Queen Mary was a luxurious British ocean liner that later served as a troopship during WWII. Today, it’s a floating hotel and museum in California.
SS Normandie - A French liner known for its Art Deco interiors and speed, the Normandie was the largest and most luxurious ship of its time. It was seized by the U.S. during WWII but tragically caught fire and capsized in New York Harbor in 1942.
SS United States - Built in 1952, this American liner was the fastest ocean liner ever, holding the Blue Riband for the fastest transatlantic crossing. It has been sitting in Philadelphia for years, awaiting restoration.
SS Andrea Doria - This Italian liner sank in 1956 after colliding with another ship off the coast of Massachusetts. Unlike the Titanic, most passengers survived due to improved rescue efforts.
RMS Lusitania - A British liner sunk by a German U-boat in 1915, leading to U.S. involvement in WWI. The tragedy killed nearly 1,200 people and remains one of the most infamous maritime disasters.

The cruise liner, Queen Elizabeth 2, moves only six inches for each gallon of diesel that it burns.
If you're connecting to the ship's onboard cell tower, you'll pay roaming fees around $5 per minute.
Luxury ocean liners were the epitome of elegance and grandeur in maritime travel, especially during the early to mid-20th century. These ships were designed not just for transportation but for opulent experiences, catering to wealthy passengers with lavish accommodations, fine dining, and extravagant entertainment. RMS Titanic, RMS Queen Mary, SS Normandie, and RMS Queen Elizabeth 2 are some of the key luxury ocean liners. With the rise of air travel in the 1950s, ocean liners became less popular for long-distance travel. Many were repurposed as cruise ships, while others became floating hotels or museums. Today, the RMS Queen Mary 2 remains the only true ocean liner still in service, while cruise ships have taken over the industry with their focus on vacation experiences.

RMS Titanic (1912) – Perhaps the most famous ocean liner, known for its tragic sinking. It featured swimming pools, Turkish baths, and a grand staircase.
RMS Queen Mary (1936) – A British liner that was one of the most advanced of its time. It later served as a troopship during WWII and is now a tourist attraction in California.
SS Normandie (1935) – A French liner renowned for its Art Deco interiors and speed. It was the largest and most luxurious liner of its era.
SS United States (1952) – The fastest ocean liner ever built, holding the Blue Riband for the fastest transatlantic crossing.
RMS Queen Elizabeth 2 (1969) – Served as a luxury liner for nearly three decades before being retired.

Cruise ships have evolved dramatically since the early 20th century! Luxury Ocean Liners, The Rise of Modern Cruising, Mega Cruise Ships, and Sustainability & Tech Innovations are some of the most significant developments:

Luxury Ocean Liners (1920s-1950s): Ships like the Queen Mary and Queen Elizabeth set new standards for elegance and transatlantic travel.
The Rise of Modern Cruising (1960s-1980s): The SS Norway (formerly SS France) was one of the first ships to focus on leisure cruising rather than transportation.
Mega Cruise Ships (1990s-Present): The Royal Caribbean’s Oasis-class ships introduced massive floating resorts with water parks, theaters, and shopping malls.
Sustainability & Tech Innovations (2020s-2025): Cruise lines are now focusing on eco-friendly ships, AI-powered experiences, and private island destinations.

The world's first purpose-built cruise ship was the Prinzessin Victoria Luise, launched in 1900 by the Hamburg America Line (HAPAG). Originally, ocean liners were repurposed for leisure travel, but this was the first ship designed specifically for cruising. The idea of cruise travel was pioneered by Albert Ballin, a German shipping executive, who saw the potential for luxury sea voyages beyond just transporting cargo and passengers, and transformed one of his ocean liners, the Augusta Victoria, into a leisurely cruising vessel for wealthy tourists in 1891. His innovative approach continued with the commissioning of the first purpose-built cruise ship, the Prinzessin Victoria Luise, in 1900, which offered first-class accommodations and sailed to destinations like the Caribbean, Mediterranean, and even around the world. Unfortunately, its career was short-lived—after just five years, the ship ran aground off Jamaica due to a navigational error, but its legacy shaped the modern cruise industry!
Harmony of the Seas, operated by Royal Caribbean International, is one of the largest cruise ships in the world, though it has since been surpassed by newer vessels like Icon of the Seas. With a gross tonnage of 226,963 GT, a length of 362 meters, and a maximum beam of 66 meters, Harmony of the Seas can carry up to 6,780 passengers and 2,300 crew members. Part of the Oasis-class, it features 18 decks packed with entertainment, dining, and recreational options, including the tallest slide at sea, a zip line, and Broadway-style shows. While no longer the absolute largest, it remains a marvel of modern cruise engineering and a favorite among travelers.
At 250,800 gross tonnage (GT), Icon of the Seas and her sister ship Star of the Seas are currently the largest cruise ships in the world. Built by Royal Caribbean as part of the groundbreaking Icon Class, these vessels represent a new era in cruise ship design, combining massive scale with cutting-edge amenities and sustainability features like liquefied natural gas propulsion. Both ships span 20 decks, carry up to 7,600 passengers at maximum capacity, and offer a wide range of entertainment, dining, and family-friendly experiences, redefining what it means to vacation at sea.
Peninsular and Oriental Steam Navigation Company is the first company to build steel SS Ravena ship in 1881, and the first company to launch the SS Valetta ship with electric lighting in 1889.
Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, which are used for transport, they typically embark on round-trip voyages to various ports-of-call, where passengers may go on tours known as "shore excursions." On "cruises to nowhere" or "nowhere voyages", cruise ships make two- to three-night round trips without visiting any ports of call. As of 2020, the world's largest passenger ship is Royal Caribbean's Symphony of the Seas. Besides the dining room, modern cruise ships often contain one or more casual buffet-style eateries, which may be open 24 hours and with menus that vary throughout the day to provide meals ranging from breakfast to late-night snacks. Ships often also feature numerous bars, lounges and nightclubs, casino, shops, spa, fitness center, library, theatre with Broadway-style shows, cinema, indoor and/or outdoor swimming pool with water slides, hot tub, pool tables, and ping pong tables for passenger entertainment.
Cruise ships today are not nuclear powered, but there is one notable exception in maritime history: the N.S. Savannah. Launched in 1959 as part of President Eisenhower’s Atoms for Peace initiative, the Savannah was the world’s first nuclear-powered merchant ship and the only one designed to carry passengers. At first glance, it resembled a typical cruise ship, complete with a swimming pool, dining room, and lounge that doubled as a movie theater. However, just meters from the passenger staterooms was a nuclear reactor, allowing the ship to travel vast distances without refueling. Though it was a technological marvel, the Savannah was ultimately retired in 1972, and no other nuclear-powered cruise ships have entered service since. Today, it serves as a museum ship in Baltimore, symbolizing a unique chapter in maritime and nuclear history.
On cruise ships, the word “banana” is informal crew slang that typically means trouble, a bad time, or disappointment. Among crew members, saying someone “got banana” can refer to receiving a scolding from a supervisor, dealing with a tough shift, or missing out on something enjoyable like shore leave or shopping. It’s part of a broader set of playful and coded language used by crew to navigate the challenges of ship life while keeping things lighthearted. Interestingly, no one seems to know exactly how the term originated, but it’s widely recognized across different cruise lines.
Cruise ships have occasionally found themselves in the crosshairs of pirates, but successful hijackings are exceedingly rare—thanks to quick thinking, advanced technology, and robust security protocols. One of the most dramatic incidents unfolded in 2005 when the Seabourn Spirit was ambushed off the coast of Somalia by pirates wielding machine guns and rocket-propelled grenades. In a bold defense, the crew deployed high-pressure water hoses and a long-range acoustic device (LRAD), blasting painful sound waves that forced the attackers to retreat. In 2008, the Nautica narrowly escaped a similar fate by accelerating to full speed and zigzagging through the waves, leaving the pirates in its wake. Then in 2009, the MSC Melody came under fire, and passengers reportedly joined the fray—hurling deck furniture at the assailants while crew members fired warning shots. These rare but real threats tend to occur in piracy-prone waters like the Gulf of Aden, prompting cruise lines to adopt cutting-edge deterrents, from sonic weapons and surveillance systems to armed escorts and strategic route planning. Though most voyages are smooth sailing, these high-seas showdowns are a reminder that even luxury liners must be ready for anything.
The Costa Concordia disaster, one of the worst cruise ship accidents in modern history, occurred on January 13, 2012, when the luxury liner struck underwater rocks off Isola del Giglio, Italy, after deviating from its planned course to perform a risky sail-by salute. The impact tore a massive hole in the hull, causing the ship to list and eventually capsize with 4,252 people on board—3,206 passengers and 1,023 crew members. Despite a lengthy rescue effort, 32 people died, including 27 passengers, 5 crew members, and 1 salvage diver, while 64 others were injured. The evacuation was chaotic and heavily criticized, especially after Captain Francesco Schettino abandoned ship prematurely; he was later convicted of manslaughter and sentenced to 16 years in prison. The disaster was attributed to human error and poor judgment, not mechanical failure or weather, and the Costa Concordia’s salvage became one of the most complex and costly maritime recovery operations ever attempted.
The one word you're generally not supposed to say on a cruise ship is “Titanic.” While not officially banned, it's considered highly taboo among passengers and crew due to its association with one of the most infamous maritime disasters in history. TikTok creator Marc Sebastian learned this the hard way during a Royal Caribbean voyage when he casually mentioned the Titanic in a dining room — prompting gasps, dropped utensils, and stunned silence. A fellow passenger even whispered, “You’re not allowed to talk about the Titanic,” highlighting how deeply ingrained this superstition is in cruise culture. Much like saying “Macbeth” in a theater, invoking the Titanic at sea is seen as inviting bad luck or unsettling fellow travelers.
On a cruise ship, the code “Charlie, Charlie, Charlie” is used to alert crew members to a potential security threat. This could include situations such as a bomb threat, the presence of pirates, or other serious security concerns. The repetition of the word “Charlie” signals the need for heightened awareness and may trigger specific safety protocols, including crew mobilization and passenger instructions. While rare, this code is part of a standardized set of emergency signals designed to maintain safety and order without causing panic.
On some cruise ships, pink flamingos—especially when displayed on cabin doors or worn as part of clothing—can serve as a subtle symbol indicating interest in the swinging lifestyle or casual encounters. While flamingos are commonly seen as fun, tropical decorations, their use as a discreet signal has grown in popularity among certain cruisers, particularly as cruise lines have begun cracking down on more widely recognized symbols like the upside-down pineapple. That said, the flamingo’s meaning can be ambiguous; not everyone displaying one is signaling interest in swinging, and many simply enjoy its playful aesthetic. Still, for those “in the know,” a pink flamingo—especially when paired with other symbols like pineapples or black rings—can be a quiet invitation to connect with like-minded individuals.
The tradition of hiding rubber ducks on cruise ships has become a popular passenger-led activity, bringing joy to kids and adults alike. Guests often decorate and tag ducks with cruise details before hiding them around the ship for others to find. However, some cruise lines now discourage this practice in public areas due to concerns about clutter, environmental impact, and interference with ship operations. While it's generally seen as harmless fun, guests are kindly asked not to hide items like rubber ducks in public spaces, especially where they might disrupt routines or safety protocols. If participating, it's best to follow cruise duck etiquette by choosing unobtrusive, accessible spots and tagging ducks with messages or social media links for finders to enjoy.
According to Cruise Hive and other sources, an upside-down pineapple displayed on a cruise cabin door is widely recognized as a discreet symbol used by individuals in the swinging community to signal interest in partner swapping. While pineapples traditionally represent hospitality, turning one upside down transforms it into a subtle code for consensual non-monogamy. Guests may use stickers, magnets, or themed décor to communicate this, and the symbol has become increasingly common across cruise ships and resorts. However, not everyone is aware of its meaning, so context and discretion are key.
While both cruise ships and airplanes are considered very safe modes of transportation, air travel is statistically safer, with the odds of a fatal accident around 1 in 11 million compared to 1 in 6 million for cruise ships. Airplanes benefit from highly redundant systems, rigorous pilot training, and rapid emergency response capabilities, whereas cruise ships—though equipped with lifeboats, safety drills, and trained personnel—face challenges due to their size and slower evacuation procedures. Health risks also vary: airplanes have advanced air filtration systems that reduce airborne illness transmission, while cruise ships are more susceptible to outbreaks like norovirus due to shared spaces and longer voyages. Environmental factors matter too, as planes can reroute around storms, while ships must navigate rough seas directly. Despite these differences, both remain far safer than driving and maintain strong safety records.
The #1 rated cruise line in several categories—including value, couples’ experiences, and Caribbean itineraries—is Celebrity Cruises, according to the latest rankings from U.S. News & World Report. Known for its modern luxury, stylish ships, and elevated dining and entertainment, Celebrity Cruises consistently earns top marks from both experts and travelers. Among its fleet, the Celebrity Edge stands out as one of the highest-rated ships overall, praised for its innovative design, upscale amenities, and standout features like the Magic Carpet—a cantilevered platform that moves along the ship’s exterior. Whether you're seeking a romantic getaway or a refined escape, Celebrity Cruises continues to set the standard for premium cruising.
Cruise ships manage human waste through a sophisticated, multi-stage process designed to meet international environmental standards. Wastewater is categorized into black water (from toilets) and gray water (from sinks, showers, and laundry). Black water is stored in sealed, odor-controlled tanks and treated onboard using biological systems that mimic land-based sewage treatment. This includes filtration, disinfection—often with UV light or chlorination—and sometimes integration with treated gray water. Once deemed safe, the treated water may be discharged into the ocean, but only under strict conditions set by the MARPOL Convention, such as being at least three nautical miles from shore and properly disinfected. Solid waste and untreated sewage are typically held until the ship docks, where they’re offloaded to municipal facilities. While some waste is legally released at sea, cruise lines increasingly invest in advanced treatment technologies and sustainability initiatives to minimize environmental impact and protect marine ecosystems.
One of the most popular things to do on a cruise is relaxing by the pool—complete with comfortable loungers, tropical cocktails, and lively entertainment like belly-flop contests and themed parties. But modern cruise ships offer far more than sunbathing: guests can enjoy outdoor movie nights under the stars, play pickleball or mini-golf, explore onboard waterparks, or even ride roller coasters like Carnival’s Bolt. Evening activities include casino games, live shows, and bar crawls across themed lounges. Whether you're seeking relaxation or adrenaline, cruise ships are packed with options to suit every mood and age group.
Cruise ships float due to a precise balance of physics and engineering, primarily driven by buoyancy, hull design, and density control. According to Archimedes’ principle, a ship stays afloat because it displaces a volume of water that weighs more than the ship itself, creating an upward force that counteracts gravity. To maximize this effect, cruise ships are built with broad, U-shaped hulls that increase water displacement and provide exceptional stability—even in turbulent seas. Despite their enormous size and weight, the ship’s overall density remains lower than that of the water it displaces, thanks to hollow interiors, lightweight construction materials, and strategic weight distribution. This combination of science and design allows these floating resorts to navigate vast oceans with ease, safety, and surprising elegance.
SS Savannah, an American hybrid sailing ship/sidewheel steamer built in 1818, was the first steamship that used a combination of steam and wind power to cross the Atlantic Ocean. She left the port of Savannah, Georgia, on May 22, 1819, arriving in Liverpool, England, on June 20, 1819. For this 29-day trip only a fraction of the distance was covered with the ship under steam power, the rest was sailed by wind power.
For cruise passengers, their average age is around 50, 85% are college/university graduates, and around 60% are married and work full time.
Allure of the Seas is the most expensive cruise ship ($1.4B) in operation in the world. It is the world’s largest passenger ship when it launched in November 2009. Built at the STX Europe Turku shipyard in Finland, this 1,187 feet long vessel measures 215 feet in width with a gross registered tonnage of 225,282 tones, 18 total decks, including a two-deck dance hall, an ice skating rink, 25 dining options and a theatre with 1,380 seating capacity. The ship can accommodate a total of 6,780 guests and 2,200 crew members.
Three years after the Titanic was crashed into an iceberg on April 15, 1912, killing over 1,500 people, the Lusitania, a British luxury liner, was sunk by a German submarine on May 7, 1915, killing 1,195 people.
SS California was one of the first steamships to steam in the Pacific Ocean and the first steamship to travel from Central America to North America in 1848.
SS Great Western, an oak-hulled paddle-wheel steamship built in 1838, was the first steamship purpose-built for crossing the Atlantic. She was the largest steamship for one year, until the British and American's British Queen went into service in 1939.
Steamships were invented in the late 18th century by William Symington, John Fitch and Robert Fulton.
MV Doña Paz, which was built in 1963 by Onomichi Zosen of Onomichi, Hiroshima, Japan, and a Philippine-registered passenger ferry, was sunk after colliding with the MT Vector on December 20, 1987, killing 4,341 people.
SS Kiangya, a Chinese passenger steamship that blew up, probably after hitting a mine (probably left by the Japanese navy) on the Huangpu River fifty miles north of Shanghai on 4 December 1948, killing over 4,000 people.
SS Mont-Blanc, a freighter built in Middlesbrough, England in 1899, was exploded in Halifax Harbor, Nova Scotia after colliding with with the Norwegian ship, SS Imo on 6 December 1917, killing over 2,000 people and injuring 9,000 more.
MV Le Joola, a Senegalese government-owned ferry, capsized off the coast of The Gambia on September 26, 2002, killing at least 1,863 people.
SS Sultana, a Mississippi River steamboat paddlewheeler, was exploded on April 27, 1865 near Memphis, Tennessee, killing over 2,400 passengers.

RMS Titanic, a British passenger liner, sank in the North Atlantic Ocean on 15 April 1912 after colliding with an iceberg during her maiden voyage from Southampton, UK to New York City, US, killing 1,502 people.
Tōya Maru, a Japanese train ferry, sank during a typhoon in the Tsugaru Strait between the Japanese islands of Hokkaidō and Honshū on September 26, 1954, killing 1,153 people .
RMS Empress of Ireland, an ocean liner, sank in the Saint Lawrence River following a collision with a Norwegian collier on 29 May 1914, killing over 1000 people.
RMS Atlantic, a transatlantic ocean liner of the White Star Line that operated between Liverpool, United Kingdom, and New York City, United States, ran onto rocks and sank off the coast of Nova Scotia on 1 April 1873, killing 535 people.
SS Princess Alice, built in 1865, was sunk on 3 September 1878 in a collision on the River Thames with the collier Bywell Castle off Tripcock Point, killing over 650 people.
SS Norge, a Danish passenger liner sailing from Copenhagen, Oslo and Kristiansand to New York, ran aground close to Rockall on St. Helen’s Reef on 28 June 1904, killing over 635 people.
MV Princess of the Stars, a ferry - built in 1984 by Ishikawajima-Harima Heavy Industries Co., Ltd. Aio, Japan - carrying over 800 people, sank in Typhoon Fengshen off the coast of San Fernando, Romblon, in the Philippines, killing 747.
The SS Camorta, an iron-hulled passenger steamship built in Scotland in 1880, met a tragic end on 6 May 1902 when it was overwhelmed by a powerful cyclone while crossing the Baragua Flats in the Irrawaddy Delta. En route from Madras (India) to Rangoon (Burma), the vessel sank with the loss of all 655 passengers—mostly Indian nationals—and 82 crew members, making it one of the deadliest maritime disasters in British colonial history. The wreck was later discovered in 15 fathoms (90 feet) of water, with only the tops of its masts visible above the surface. The tragedy prompted widespread mourning and remains a haunting chapter in the annals of early 20th-century sea travel.
Cruise ship sizes today span an impressive range, with gross tonnage starting around 30,000 tons for smaller luxury or expedition vessels and climbing to over 250,000 tons for the largest mega-ships like Icon of the Seas. Ships between 30,000–50,000 GT tend to offer intimate experiences and can reach ports off the beaten path, while mid-sized vessels of 50,000–100,000 GT balance amenities with flexibility for regional travel. Larger ships in the 100,000–180,000 GT bracket pack in extensive entertainment, dining, and family-oriented features, and the true giants—those in the 180,000–250,000+ GT class—are floating cities that can carry over 7,000 guests, complete with waterparks, theaters, and entire themed neighborhoods.
The RMS Titanic, a luxurious British passenger liner operated by the White Star Line, was among the largest and most elegant ships of its era. Stretching 882 feet 9 inches in length, 92 feet 6 inches in width, and weighing 46,329 gross tons, she was built to carry over 2,400 passengers and around 900 crew members. On her maiden voyage from Southampton, England, to New York City, tragedy struck late on 14 April 1912, when Titanic collided with an iceberg in the North Atlantic Ocean. She sank in the early hours of 15 April, claiming the lives of approximately 1,500 of the 2,224 people on board—a disaster that ranks among the deadliest peacetime maritime tragedies in history. The catastrophic loss spurred profound reforms in maritime safety, including enhanced lifeboat regulations and the creation of the International Ice Patrol, reshaping ship safety standards for generations to come.
As of 2025, the world’s three leading cruise giants—Carnival Corporation, Royal Caribbean Group, and Norwegian Cruise Line Holdings (NCLH)—collectively carry approximately 78% of global cruise passengers. Carnival Corporation leads the industry with 41.5%, followed by Royal Caribbean Group at 27%, and NCLH at 9.4%. Their vast market share reflects expansive fleets, wide-ranging itineraries, and multi-brand portfolios that span regions from the Caribbean to Asia, solidifying their dominance in global cruise tourism.
As of 2025, the global cruise fleet has grown to more than 320 ships, with estimates ranging from 323 to 360 vessels depending on whether you count those actively sailing, under construction, or temporarily docked for maintenance. These ships represent a diverse array of experiences across 51 ocean cruise lines and 27 river cruise operators, with a combined passenger capacity exceeding 769,000 guests. The fleet spans everything from boutique luxury yachts designed for intimate journeys to colossal floating resorts like Icon of the Seas, which alone can accommodate over 7,600 travelers—essentially the population of a small town, cruising in style.
In 2024, over 34.6 million people set sail on cruises around the globe, with North America leading the charge, accounting for more than 20 million passengers—nearly 60% of the global market. The United States alone contributed approximately 19 million cruise travelers, cementing its status as the powerhouse of the industry. This surge in cruising is driven by bustling departure ports such as Florida, California, and Alaska, paired with a high demand for Caribbean getaways. In 2023, the North American cruise sector infused a staggering $36 billion into the U.S. economy, fueling over 290,000 jobs and reinforcing the region’s central role in global cruise tourism.
Cruise ships can explore a vast global network of more than 2,000 ports across all seven continents, offering travelers an unmatched gateway to the world. From idyllic islands like Cozumel and Bora Bora to storied cities such as Venice and Istanbul, each destination reveals a unique mosaic of culture, scenery, and adventure. Whether gliding through the turquoise waters of the Caribbean, cruising past Norway’s dramatic fjords, or docking in vibrant Asian hubs, the incredible diversity of port experiences is what makes cruising feel truly magical—a seamless journey from one breathtaking chapter to the next.
In 2024, Florida’s three powerhouse cruise ports—PortMiami, Port Canaveral, and Port Everglades (Fort Lauderdale)—collectively welcomed over 19.8 million passengers, accounting for more than 50% of all cruise embarkations in the U.S.. Leading the charge, PortMiami handled 8.23 million travelers, reclaiming its title as the world’s busiest cruise port, while Port Canaveral followed closely with 7.6 million passengers and is projected to reach 8.4 million in 2025, potentially surpassing Miami. Port Everglades served 4 million passengers in 2024, with forecasts indicating 4.4 million in the coming year. Florida’s strategic location, favorable climate, and proximity to sought-after destinations like the Caribbean make it a natural hub for cruise tourism, especially for major vessels such as Icon of the Seas and Utopia of the Seas.
The Caribbean reigns as the world’s top cruise destination, drawing more passengers than any other region.

Royal Caribbean Cruise Line owns 10 of the 14 largest cruise ships in the world, showcasing its dominance with colossal vessels like Icon of the Seas and Star of the Seas, each measuring 1,198 feet long and weighing in at 250,800 gross tons. These ships, launched in 2024 and 2025 respectively, belong to the cutting-edge Icon Class and feature everything from multi-level waterparks to ice rinks. Other giants in its fleet include Utopia of the Seas (236,860 GT, 1,188 ft, 2024), Wonder of the Seas (236,857 GT, 1,188 ft, 2022), Symphony of the Seas (228,081 GT, 1,184 ft, 2018), and Harmony of the Seas (226,963 GT, 1,188 ft, 2016). The Oasis Class ships like Allure of the Seas (225,282 GT, 1,187 ft, 2010) and Oasis of the Seas (225,282 GT, 1,187 ft, 2009) continue to impress with massive dimensions of 1,187 feet in length. These floating cities are marvels of modern engineering, housing thousands of guests and crew and redefining luxury at sea.
Once the largest cruise ship in the world upon its debut in 2010, Allure of the Seas has since been eclipsed by newer maritime giants. As of 2025, the title belongs to Icon of the Seas, another Royal Caribbean marvel, boasting a staggering 1,196.7-foot length, gross tonnage of 248,663, and capacity for up to 7,600 passengers. Despite its dethroning, Allure of the Seas remains firmly in the top 10, with updated stats of 225,282 GT, a length of 1,180 feet, and room for approximately 6,780 guests. It recently received a $100 million transformation, adding thrills like multi-story waterslides, a high-tech escape room, and enhanced dining options, keeping this iconic vessel fresh, fun, and fiercely competitive on the high seas.
In 2002, Carnival Cruise Line launched the Carnival Legend, part of its Spirit Class fleet, with a gross tonnage of 88,500, a length of 963 feet, and accommodations spread across 12 passenger decks. The ship features 1,062 staterooms, including approximately 556 private balcony staterooms, and is designed to carry up to 2,610 passengers with a dedicated crew of around 930 members. Though often mistaken for larger vessels, Carnival Legend offers an intimate yet spacious cruise experience, blending classic design with modern amenities.
Azamara Quest originally entered service in November 2000 as R Seven for Renaissance Cruises, with a gross tonnage of 30,277, a length of 593 feet, and a beam of 95 feet. After changing hands and names several times—including Delphin Renaissance and Blue Moon—she officially began sailing as Azamara Quest in October 2007 under Azamara Cruises. The ship accommodates approximately 710 passengers at double occupancy, supported by a crew of around 410 members, offering a nearly 1:2 staff-to-guest ratio for personalized service.
In 2007, Karin Stahre-Janson made history when she became the captain of Royal Caribbean’s Monarch of the Seas, becoming the first woman to command a modern “mega” cruise ship. Born in Strömstad, Sweden, she started her maritime career on cargo vessels before transitioning to cruise ships, eventually rising through the ranks at Royal Caribbean. The Monarch of the Seas was no small assignment—it’s 880 feet long, carries around 2,400 guests and 850 crew members, and sails multi-day cruises along the Pacific coast. Her promotion was a landmark moment not just for Royal Caribbean, but for the entire cruise industry, inspiring a wave of female leadership at sea
Constructing a cruise ship can cost anywhere from $500 million to over $1 billion, depending on its size and features. These modern marvels often resemble floating cities, with luxurious amenities like suites, theaters, pools, and even roller coasters. The price escalates due to advanced engineering and safety systems, compliance with international regulations, and the inclusion of environmental innovations such as LNG propulsion and water treatment technologies. Interior design also plays a huge role, since ships feature high-end dining, spas, and entertainment areas that rival five-star hotels. And beyond building the vessel, running a cruise line involves staffing, marketing, port partnerships, and ongoing maintenance to keep everything smooth sailing.
The Oasis of the Seas, one of the largest cruise ships in the world, needed around 158,503 gallons (or 600,000 liters) to cover its massive surface. That amount isn’t just for beauty—it protects the ship from saltwater corrosion, harsh weather, and wear over time. Given the vessel spans more than 1,180 feet with 16 decks, it’s basically like painting a small floating city. Some shipyards even mix specialized coatings with antifouling properties to keep marine life from hitching a ride.

Whether you need a passport for a cruise depends on your citizenship and itinerary. U.S. citizens on closed-loop cruises—those that begin and end at the same U.S. port and travel within the Western Hemisphere—may not need a passport and can often use a government-issued photo ID along with a birth certificate. However, if the cruise starts or ends in a different port, involves international air travel, or visits countries requiring visas, a valid passport book is required. Even when not mandatory, carrying a passport is strongly recommended in case of emergencies, such as needing to fly home from a foreign country. Cruise lines may also have specific documentation policies, so it’s important to confirm requirements before departure.
Cruise ships primarily use Marine Diesel Oil (MDO), a specialized blend of distillates and heavy fuel oil designed for marine engines. Traditionally, many ships relied heavily on Heavy Fuel Oil (HFO)—also known as bunker fuel—due to its low cost, despite its thick, tar-like consistency and environmental drawbacks. In response to growing environmental concerns and international regulations like the IMO’s sulfur cap, cruise lines are increasingly shifting toward cleaner alternatives, including Liquefied Natural Gas (LNG), which burns more cleanly and reduces emissions. Some newer ships, such as those in Royal Caribbean’s and Celebrity Cruises’ fleets, are even exploring methanol and renewable diesel as part of their fuel mix. The choice of fuel depends on the ship’s age, engine type, and itinerary, but the industry is clearly moving toward more sustainable propulsion technologies.
A cruise ship captain’s salary can vary widely depending on experience, ship size, and the cruise line, but typically ranges from $80,000 to $195,000 per year. Captains of mega cruise ships or luxury lines with extensive experience can earn upwards of $200,000 to $350,000 annually, and in rare cases, even $400,000. On the lower end, newly promoted captains or those working on smaller vessels may earn around $45,000 to $50,000 per year. Factors influencing pay include years of service, education (such as a master’s degree in maritime studies), and the prestige or size of the cruise line. Despite the high salary, the role comes with immense responsibility—overseeing the safety of thousands of passengers and crew, managing ship operations, and being on call 24/7 while at sea.
On cruise ships, a rubber ducky has become a symbol of a lighthearted, passenger-led tradition known as the cruise duck hunt. Started in 2018 by a young girl named Abby Davis, the trend involves guests bringing rubber ducks aboard and hiding them in creative spots around the ship for others to discover. Each duck often includes a tag with the hider’s name, hometown, and sometimes a message or link to a social media group, encouraging interaction and shared joy among passengers. It’s a bit like geocaching, but simpler—and with ducks. While cruise lines don’t officially sponsor the activity, it has grown into a global phenomenon with thousands of participants and dedicated Facebook groups. The goal is to spread smiles, spark curiosity, and connect travelers through a quirky, unexpected treasure hunt.
Cruise ships don’t have traditional police officers like those on land, but they do maintain a robust security infrastructure led by trained personnel and overseen by the ship’s captain, who holds significant legal authority at sea. Onboard security teams—often composed of individuals with backgrounds in law enforcement or the military—are responsible for maintaining order, investigating incidents, preserving evidence, and securing crime scenes when necessary. In serious cases, such as assault or theft, the ship may use its brig (a secure holding cell) to detain individuals until authorities can intervene. Jurisdiction over crimes depends on a complex mix of factors, including the ship’s location (territorial vs. international waters), its country of registration (flag state), and the nationalities of those involved. When a ship docks in a U.S. port, for example, agencies like the FBI or Coast Guard may take over investigations. While cruise ships don’t carry uniformed police, they operate under a well-defined legal framework to ensure safety and accountability at sea.
Cruise ships typically have a small detention area known as a brig, which serves as a temporary holding cell for individuals who violate ship rules or engage in illegal or dangerous behavior. These brigs are usually located on lower decks, near the security offices and sometimes close to the ship’s morgue. Far from the dramatic jails seen in movies, a cruise ship brig is a basic, secure room—often with a bed, toilet, and minimal furnishings—designed for short-term confinement until the ship reaches port and authorities can intervene3. Cruise lines use the brig as a last resort, preferring alternatives like cabin arrest for less severe incidents. While most passengers will never see or even know about the brig, it plays a crucial role in maintaining safety and order at sea.

▷ Military Ships

Cruise ships and military cruisers, though both large vessels, serve vastly different purposes. Cruise ships are floating cities designed for leisure, carrying thousands of passengers on round-trip voyages with amenities like pools, theaters, and restaurants, powered by diesel-electric or gas turbines and equipped with desalination systems for freshwater. In contrast, military cruisers are strategic warships built for combat, air defense, and fleet command, typically second in size only to aircraft carriers. They house advanced propulsion systems, radar, missile launchers, and electronic warfare capabilities, with a focus on speed, maneuverability, and survivability. While cruise ships prioritize comfort and entertainment, cruisers are engineered for tactical dominance and operational endurance.

Feature	Cruise Ships	Military Cruisers
Primary Purpose	Leisure travel, entertainment, and tourism	Naval warfare, air defense, and fleet command
Passengers	Thousands of civilians (up to 6,000+)	Hundreds of military personnel
Design Focus	Comfort, luxury, amenities (pools, theaters, restaurants)	Speed, stealth, armor, and weapons systems
Power Generation	Diesel-electric or gas turbines for propulsion and onboard systems	Advanced propulsion (often gas turbines or nuclear), optimized for maneuverability and endurance

Weapons	Weapons	Equipped with missiles, guns, radar, and electronic warfare systems
Size	Often larger in volume and length (e.g., Symphony of the Seas is ~362m long)	Smaller but denser with tech and armament (e.g., Ticonderoga-class cruiser is ~173m long)
Cost	~$1 billion per ship	~$1–2 billion per ship, depending on tech and armament

In the U.S. Navy, CVN is the designation for a nuclear-powered aircraft carrier, combining historical and functional elements into a single code. Together, CVN identifies a nuclear-powered aircraft carrier capable of launching and recovering fixed-wing aircraft, such as the USS Gerald R. Ford (CVN-78) or USS Nimitz (CVN-68). These vessels serve as floating airbases and are among the most powerful and strategically important assets in the Navy’s arsenal.

C: Originally stood for "cruiser," reflecting the early days when aircraft carriers were sometimes converted from cruisers. Though modern carriers are purpose-built, the "C" remains as a legacy marker.
V: Indicates "heavier-than-air" aircraft, referring to fixed-wing planes like fighter jets and bombers that operate from the carrier's deck.
N: Stands for "nuclear-powered," meaning the ship uses nuclear reactors for propulsion, allowing it to sail for decades without refueling.

Aircraft carriers are typically wider and taller due to their massive flight decks and superstructures, designed to launch and recover aircraft efficiently. However, cruise ships are usually longer and heavier, as they prioritize passenger capacity, amenities, and structural volume. While aircraft carriers are built for military dominance and feature expansive flight decks, cruise ships often surpass them in overall length and weight due to their civilian-focused design. For example, the USS Gerald R. Ford (a U.S. Navy aircraft carrier) is about 333 meters long and displaces around 100,000 tons, while Wonder of the Seas (a Royal Caribbean cruise ship) stretches to 362 meters and weighs over 236,000 gross tons. The difference lies in purpose: carriers are optimized for combat operations, while cruise ships are engineered for comfort, luxury, and scale.
Cruisers are generally larger and more powerful than destroyers, both in size and combat capability. Built as heavily armed and armored surface combatants, cruisers often serve as command ships and provide long-range fire support, boasting advanced radar systems and vertical launch missile arrays for multi-role warfare. Most cruisers exceed 180 meters in length and displace over 10,000 tons, making them formidable assets in any naval fleet. Destroyers, while still highly capable, are smaller and more agile—designed primarily for anti-aircraft, anti-submarine, and surface warfare. The Zumwalt-class destroyer is an exception, stretching 190 meters and displacing 16,000 tons, but most destroyers fall within the 8,000–10,000 ton range. Frigates are the smallest of the trio, typically under 150 meters, and are specialized for escort missions, patrol duties, and submarine hunting. Each class plays a distinct role, but cruisers remain the heavyweight champions of surface warfare.
The USS Gerald R. Ford (CVN-78) is the largest warship in the world and the lead vessel of the new Ford-class aircraft carriers, which are set to replace the aging Nimitz-class fleet. Commissioned in 2017, the Gerald R. Ford represents a major leap in naval engineering, featuring cutting-edge systems like the Electromagnetic Aircraft Launch System (EMALS), advanced radar, and improved energy efficiency. During operations, it can receive over a million gallons of jet fuel from replenishment tankers like the USNS Kanawha, enabling extended deployments without returning to port. The Ford-class is designed to be smarter, leaner, and more lethal, with reduced crew workload and long-term cost savings, making it the backbone of future U.S. naval power
The HMS Bulwark, a London-class pre-dreadnought battleship of the Royal Navy, suffered one of Britain's deadliest non-combat naval tragedies on 26 November 1914. While anchored near Sheerness in the Medway Estuary, a catastrophic internal explosion ripped through the vessel around 7:50 a.m., just as the crew was starting their morning. The blast was so immense that the battleship was virtually obliterated—only scattered fragments remained, and debris rained down miles away, even into the streets of Sheerness. Of the estimated 741 crew members, only 12 survived, underscoring the scale of devastation. Eyewitnesses recalled a towering column of flame and smoke, followed by thunderous detonations that rocked nearby ships such as HMS Implacable. An official inquiry later attributed the disaster to overheated cordite charges stored dangerously close to a boiler-room bulkhead, sparking a fatal chain reaction. The incident led to critical reforms in naval ammunition handling and storage, forever shaping safety protocols in British naval operations.
The Sussex, an 80-gun third-rate ship of the line of the English Royal Navy, built in 1693, was sunk in a severe storm on 1 March 1694 off Gibraltar; 500 crew members, but 2, and 10 tons of gold coins were lost with the ship.
Ottoman frigate Ertuğrul, a Ottoman Navy war ship, launched in 1863, carrying 533 sailors, was lost in a severe storm off Kushimoto, Japan, on 18 September 1890.
