Length of a cruise ship (Length Overall / LOA)

The cruise ship length is professionally referred to as LOA (length overall), meaning the maximum length between the two most distant points on its hull. LOA may also include the tip of the bowsprit - the pole extending from the ship's prow (usually on tall sailing ships, yachts, and smaller boats). The bowsprit is the "winning" part of the ship when competing in a race or during trials/speed tests.

Another passenger cruise ship length measuring (though not included in this survey) is called LWL. LWL signifies "loaded waterline length" (or just "waterline length"). It excludes the total length, denoting only the length at the point where the vessel sits in the water. The LWL measure plays an important role when assessing some ship properties, like "hull speed" (aka "displacement speed"), water displacement, the amount of paint needed for the ship's bottom, etc.

Longest cruise ship in the world

The longest cruise ships by size also occupy the first two positions in the list of the largest cruise ships of the world by passenger capacity and gross tonnage. The humongous Royal Caribbean's floating cities Allure and Oasis boast the whole 360 meters in length (1,181 ft), and breadth of 47 meters (154 ft), the unbelievable for a passenger cruise ship tonnage of 225,300 tons, and max crew-passenger capacity of almost 8,500 (2,170+6,300) - each!

Weight of a cruise ship (tonnage) and draft

The size (tonnage weight) of a cruise ship is measured in "gross tonnage" (GT). It relates to the vessel's internal volume (keel to funnel* and to the outside of the hull) and applying a mathematical formula. The cruise ship tonnage is generally used for determining registration fees, port fees, safety rules, regulations. Another ship data (though not included in this survey) is the vessel's "deadweight tonnage" (DWT), which is the weight a vessel can safely carry (cargo, passengers, etc).

The cruise ship draft (or draught) measures the number of meters/feet from the waterline to the lowest point of the keel - or the ship's "invisible" portion below the surface (and especially when loaded). The cruise ship's draft is very important when considering docking in a particular port, sailing through channels or the inland waterways of the continents (rivers and canals).

*Note: Actually, the ship's funnel is the only part of the enclosed interior space that is NOT included in its Gross Tonnage measurement.

Cruise ship weight

As one of our fans Mr John Spooner (cruiser / Retired Master Mariner) have pointed out, the "Gross Tonnage" weight is a measurement of VOLUME, and not of MASS. GT  is an index related to marine vessels' overall internal volume. According to Wikipedia's definition:

• "Gross Tonnage" (GT) calculations are based on the volume of all the ship's enclosed spaces.
• "Gross Register Tonnage" (GRT) is the vessel's total internal volume measured in "register tons" (each ton equals 100 ft3 / 2,83 m3).
• Neither GT nor GTR measures the vessel's displacement (mass), but really show how big cruise ships are.
• "Deadweight Tonnage" (DWT) measures how much weight a cruise ship (or any of the marine vessel types) can carry safely. This a weighted sum of the vessel's cargo (incl provisions, passengers, crew), fuel, water (fresh and ballast), etc.
• "Displacement Tonnage" is how much weight the water that a cruise ship (any vessel) displaces when floating (the total weight of the ship / including its contents). Displacement is usually applied to the navy rather than commercial marine vessels. It is measured when the ship is loaded at full capacity.

How Much Do Cruise Ships Weigh? 

Picture a city that floats. It’s got thousands of people, all kinds of fun stuff to do, and it moves across the ocean. Sounds like something from a sci-fi movie, right?

But it’s actually what cruise ships are like today. I’ve spent years working with these giant ships, getting to know every nook and cranny.

People always ask, “Just how heavy are these things?” It’s a simple question, but the answer is pretty fascinating.

It touches on everything from how they’re built to the mark they leave on the planet. In this article, we’re going to clear that up, breaking down the massive weight of cruise ships in a way that’s easy to grasp.

Average Weight of Cruise Ship s

How we measure a cruise ship.

When we talk about how heavy a cruise ship is, we often use the term “gross registered tonnage” or GRT. You might think this is about how much the ship weighs, but it’s actually about how much space is inside the ship. It measures the ship’s volume, not its weight.

There’s another term, “deadweight tonnage,” that’s about the weight of what the ship carries. This includes cargo, fuel, and even the weight of all the people on board.

To figure out a ship’s GRT, we look at how big it is inside. This tells us how many people it can carry. This way of measuring helps us compare the size of different ships.

Gross Tonnage and Modern Cruise Ships

When you’re picking a cruise for your vacation, you might hear a lot about gross tonnage. Here’s why it’s important: bigger ships with more gross tonnage usually have more fun stuff to do, more room to relax, and they’re better at handling big waves. This means you get a better, smoother trip.

Let’s look at how cruise ships have changed size over the years:

• RMS Titanic (1912): When it set sail, the Titanic was the biggest ship around, at 46,328 tons.
• RMS Queen Elizabeth (1940): This ship was huge for its time, at 83,673 tons, and it kept the title of the largest ship until 1972.
• Sovereign of the Seas (1987): This ship, weighing 73,529 tons, was a game-changer for Royal Caribbean, starting the trend of “mega” cruise liners.
• Carnival Destiny (1996): Now called Carnival Sunshine, it was the first ship to go over 100,000 tons, hitting 101,353.
• Freedom of the Seas (2006): This giant, at 154,407 tons, doubled the size of earlier big ships, fitting way more people.
• Icon of the Seas: Right now, this is the biggest cruise ship out there, at a massive 250,800 tons. It’s almost 1200 feet long and 160 feet wide.
• Small Cruise Ships: These are between 10,000 and 80,000 tons. They’re cozy and less crowded.
• Mid-Size Cruise Ships: They’re in the middle, between 80,000 and 130,000 tons, with a good mix of features and space.
• Large Cruise Ships: These big ships range from 130,000 to 180,000 tons and have lots of amenities.
• Mega Cruise Ships: Like the Oasis of the Seas, they’re huge, between 180,000 and 260,000 tons, and have everything you could want.

So, cruise ships come in all sizes, and the gross tonnage tells you a lot about what to expect on your trip.

World’s Heaviest Cruise Ships

Royal Caribbean Leads the Pack

Royal Caribbean International has the biggest cruise ship out there, the Icon of the Seas. This huge ship has a gross tonnage of 250,800, making it the heaviest in the world right now.

To give you an idea of how big that is, think about the Titanic. It was only 46,328 tons, which is way smaller than the Icon of the Seas and other big cruise ships today.

And it’s not just the Icon of the Seas. Royal Caribbean also has the next two biggest ships, the Wonder of the Seas and the Symphony of the Seas. They’re all about making sure you have plenty of space and things to do on your cruise.

Big Cruise Ships and Their Cool Features

What you’ll find on huge cruise ships.

When you get on a big cruise ship, like Harmony of the Seas or Allure of the Seas, you’ll see they have some really cool stuff because they’re so big.

These ships can have thousands of people on them and offer all kinds of fun things to do. Here’s what you might find on a big cruise ship:

• A bunch of swimming pools, and some even have machines that let you surf.
• Super fun water slides that could beat the ones in Orlando.
• Theaters that are just like the ones where you watch plays and movies.
• Shopping areas that feel like you’re walking through a mall.
• Plus, things you wouldn’t expect like ice-skating rinks, roller coasters, and bumper cars.

All these features make being on a cruise ship a blast, turning it into a floating city of fun.

How Big Cruise Ships Float

Have you ever thought about how huge cruise ships float despite being so heavy? It’s all about buoyancy. These ships are huge, and their big hulls push away lots of water. This creates an upward force that holds the ship up, balancing out its weight.

Ships like the Oasis of the Seas are built super safe. Thanks to modern design and technology, these ships not only float but stay balanced and smooth while sailing.

But, the bigger the ship, the bigger the challenges. Making sure the ship is stable, easy to move, and doesn’t use too much fuel gets harder the larger it gets. Plus, there are environmental concerns and the tricky business of moving in tight spots or docking at small ports.

So, these massive cruise ships are really something special. They’re not just big and fancy; they’re examples of smart engineering, designed to give people great experiences while dealing with the laws of nature.

How Big Cruise Ships Are Built to Handle the Sea

Building the biggest cruise ships is pretty amazing. These giant ships are like floating cities, but making them work right comes with some big challenges. Because they’re so huge and heavy, the people who build and run them have to figure out smart ways to deal with everything from moving them around to keeping them safe on the water. It’s all about using some cool engineering to make sure these massive ships can sail smoothly.

Making Big Ships Move Easily

Getting big cruise ships to move around in docks and tight places is super challenging. It’s a lot like trying to squeeze a big bus into a tiny parking spot.

Engineers have come up with a smart way to deal with this: Azipods. Imagine these as huge motors that can turn any which way, just like an owl can turn its head. This lets the captain move the ship in any direction they need to, whether that’s forward, backward, or sideways.

There’s also something called bow thrusters. These work like extra boosts of power to help turn the ship’s front end. It’s as if you had a bunch of strong tugboats all pushing together to help the ship pivot. Pretty clever, right?

Tackling Fuel Consumption on Giant Cruise Ships

Fuel consumption is a major issue for cruise ships, as they use a lot of fuel. To address this, engineers have come up with some smart strategies. One approach is improving the design of the ship’s hull. By shaping the hull to slice through water more smoothly, the ship faces less resistance, which means it doesn’t need as much fuel.

There’s also a shift towards using alternative fuels, such as liquefied natural gas (LNG). LNG is not only more efficient but also cleaner and better for the environment. This move is helping to make cruise ships greener and more sustainable.

Handling Storms on Big Cruise Ships

Sailing on a huge cruise ship through a storm can feel like a wild ride. Even though these ships are really tall and big, they can still sway a lot. The funny thing is, the smaller the ship, the more you feel this swaying.

To help everyone on board stay comfortable and not get seasick, engineers have come up with a cool idea: stabilizers. Think of them like big underwater wings on the sides of the ship. They move around to keep the ship from rocking too much, kind of like how you’d balance yourself on a tightrope.

Also, these ships have high-tech tools to check the weather and help the captain avoid the worst of the storm. This way, even on the biggest ships, they can find a smoother path through the ocean.

So, with all these smart designs, cruising on these big ships can be really fun and not too shaky, even when the sea gets rough. It’s all about the clever tricks they use to make the ride smooth.

Understanding Cruise Ship Weight

And there you go. Today’s cruise ships are not just big; they’re marvels of engineering that manage to float effortlessly despite their massive size. These giants of the sea can carry all sorts of fun stuff, from swimming pools and slides to theaters.

Next time someone mentions the Titanic as the biggest ship, you’ll know better. Today’s smaller cruise ships are already larger than the Titanic, and the largest of them all, the Icon of the Seas, is over five times heavier than the Titanic was.

The cruise industry has evolved dramatically over the last century, especially in the last few decades. It’s exciting to think about what innovations we might see in the future!

Additionally, they house various machinery, including propulsion systems, generators, air conditioning units, and life-saving equipment. All of these elements add to the weight of the ship.

By considering these factors, it becomes evident that a cruise ship’s weight is a culmination of multiple elements working together to create these colossal vessels. Now, let’s explore how these weights compare to other large vessels.

Structural Weight Components

The structural weight components of a cruise ship form the foundation of its construction and contribute significantly to its overall weight. These components play a vital role in providing stability, strength, and safety while withstanding the forces of the ocean. Here are some key structural elements that contribute to a cruise ship’s weight:

• Hull: The hull of a cruise ship is the outermost layer that encloses the vessel’s interior spaces and provides buoyancy. Typically constructed from steel or aluminum alloys, the hull is designed to withstand the impact of waves and protect the ship’s internal systems. The thickness and strength of the hull contribute significantly to the ship’s weight.
• Superstructure: The superstructure refers to the upper decks and structures of the cruise ship, including cabins, lounges, restaurants, and entertainment venues. These areas are constructed using materials such as reinforced steel or aluminum and contribute to the overall weight of the ship.
• Decks: Cruise ships consist of multiple decks, which provide access to various facilities and amenities. Decks are built using sturdy materials and are designed to support the weight of passengers, crew, and equipment. The number and size of the decks vary depending on the size and design of the ship, influencing its overall weight.
• Machinery and Systems: Cruise ships house a variety of machinery and systems, such as propulsion systems, generators, air conditioning units, and water treatment systems. These systems contribute to the overall weight of the ship but are essential for the smooth operation and comfort of passengers and crew.
• Ballast: Cruise ships utilize ballast tanks, which are compartments filled with water or other heavy fluids, to maintain stability. By adjusting the amount of water in these tanks, the ship’s weight distribution can be manipulated to counteract the effects of waves and ensure a comfortable ride. The water in the ballast tanks adds to the overall weight of the ship.

These structural weight components are meticulously designed and constructed to ensure the safety and stability of the cruise ship. While they contribute significantly to the ship’s weight, they are essential for the vessel’s robust construction and ability to withstand the harsh elements of the open ocean.

Passenger and Crew Weight

Passengers and crew members are a significant contributing factor to the overall weight of a cruise ship. These individuals, along with their personal belongings, add substantial mass to the vessel. Let’s take a closer look at how passenger and crew weight influences the overall weight of a cruise ship:

Passengers: Cruise ships are designed to accommodate a large number of passengers, ranging from hundreds to several thousand, depending on the size of the vessel. Each passenger brings their own weight and personal belongings, including luggage, clothing, and other essentials. As passengers embark on the cruise, the collective weight of their presence adds up significantly.

Crew Members: In addition to passengers, cruise ships have a substantial crew that ensures the smooth operation and safety of the vessel. This includes officers, cabin stewards, chefs, bartenders, entertainers, and maintenance personnel. Each crew member adds their own weight, as well as their belongings and essential equipment needed to perform their duties.

When calculating the weight of passengers and crew members, it is essential to consider the diversity of individuals on board. People come in different shapes and sizes, and their weight can vary significantly. Cruise lines typically use an average weight per person when estimating the overall passenger and crew weight.

It’s worth noting that passenger and crew weight can fluctuate throughout the duration of a cruise. As passengers and crew consume food and beverages on board, their weight will naturally change. Cruise ships may also encounter weight variations in response to embarkation and disembarkation processes as new passengers come on board and others leave the ship.

Passenger and crew weight is a substantial factor in the overall weight calculation of a cruise ship. It’s essential for cruise lines to account for this weight accurately to ensure the ship’s stability and safety during its operations.

Fuel and Water Weight

Fuel and water are essential resources for a cruise ship’s operation, and they contribute significantly to the overall weight of the vessel. Let’s explore how fuel and water weight factors into the equation:

Fuel: Cruise ships require a vast amount of fuel to power their engines and generate electricity. The type of fuel used can vary, from heavy fuel oil to cleaner alternatives like marine diesel or liquefied natural gas (LNG). The quantity of fuel on board depends on the ship’s range, itinerary, and sailing duration. Fuel is typically stored in dedicated tanks deep within the ship’s hull, contributing to its overall weight.

Water: Water is another crucial resource on board a cruise ship. It is required for a variety of purposes, including drinking water, showers, pools, kitchens, and laundry facilities. Cruise ships carry a significant amount of freshwater in storage tanks or generate it through desalination processes. The weight of water, whether stored or produced on board, adds to the ship’s overall weight.

Both fuel and water consumption can vary based on various factors, such as the ship’s speed, itinerary, and operational requirements. Cruise lines carefully plan and manage their fuel and water supply to ensure that they have enough resources for the duration of the voyage without exceeding the ship’s weight limits.

It’s worth mentioning that in recent years, the cruise industry has made significant efforts to reduce fuel consumption and improve environmental sustainability. This includes the implementation of advanced propulsion systems, energy-efficient technologies, and the exploration of alternative fuels to minimize the environmental impact associated with fuel consumption at sea.

While fuel and water weight are necessary for a cruise ship’s operations and passenger comfort, cruise lines continually strive to find innovative solutions to optimize efficiency and reduce their environmental footprint.

Cargo Weight

In addition to passengers and crew, cruise ships often carry various types of cargo, which contribute to the overall weight of the vessel. Let’s explore the role of cargo weight on a cruise ship:

Provisions and Supplies: Cruise ships need to stock up on provisions and supplies to meet the needs of passengers and crew during the voyage. This includes food, beverages, toiletries, cleaning supplies, and other essential items. These provisions are typically stored in designated areas on the ship and significantly add to its weight.

Equipment and Machinery: Cruise ships house a vast array of equipment and machinery to support onboard operations. This may include items such as maintenance tools, spare parts, medical equipment, and even vehicles used for shore excursions. The weight of these items, which are strategically stored and secured on the ship, contributes to its overall cargo weight.

Other Goods: Cruise ships may also carry other types of cargo, such as merchandise for onboard shops, artwork for gallery displays, or equipment for entertainment and recreational activities. These goods are carefully loaded onto the ship and play a role in both guest experience and revenue generation.

Each cruise ship has designated storage areas and loading capabilities to accommodate the cargo being carried. Cruise lines meticulously plan and manage the cargo load to ensure even distribution and stability throughout the voyage. They take into account factors such as weight limits, structural integrity, and accessibility to efficiently handle and store the cargo.

The cargo carried by cruise ships varies depending on the ship’s size, itinerary, and the needs of the passengers and crew. Cruise lines work closely with suppliers and logistics providers to ensure that the necessary cargo is onboard and ready for the voyage.

By efficiently managing and distributing cargo weight, cruise lines can maintain the ship’s stability and ensure a safe and comfortable journey for everyone on board.

These systems include engines, generators, electrical systems, stabilizers, and computerized control systems. The weight of these essential components contributes significantly to the ship’s overall weight.

Each cruise ship is carefully designed and equipped to provide an exceptional onboard experience for passengers. Cruise lines meticulously select amenities and equipment that meet the needs and preferences of their target audience while considering the impact on the ship’s weight and stability.

Efficient distribution of equipment and amenities weight is crucial for maintaining the ship’s balance and stability during voyages. Careful planning and engineering ensure that the weight is well-distributed and does not compromise the ship’s safety or performance.

Overall, the vast array of amenities and equipment on a cruise ship enhances the passenger experience but also contributes to the ship’s overall weight. It’s a delicate balance to provide outstanding onboard facilities while meeting the necessary weight considerations for a safe and enjoyable voyage.

Comparison to Other Large Vessels

Cruise ships are often considered some of the largest and most impressive vessels on the water. However, in terms of weight, how do they compare to other large maritime counterparts? Let’s examine how cruise ship weights stack up against other types of massive vessels:

Tankers: Tankers, which transport oil, gas, or other liquids, can be significantly larger and heavier than most cruise ships. The weight of a tanker can vary widely depending on its size and cargo capacity. Ultra-large crude carriers (ULCCs) can weigh well over 200,000 tons, dwarfing even the largest cruise ships.

Cargo Ships: Cargo ships, designed primarily for transporting goods, come in various sizes and configurations. Some cargo ships, such as container ships or bulk carriers, can rival the tonnage of cruise ships. The weight of a cargo ship can range from tens of thousands to hundreds of thousands of tons.

Naval Carriers: Naval aircraft carriers, built for military purposes, are among the most massive vessels ever constructed. These immense warships weigh hundreds of thousands of tons, with the largest aircraft carriers surpassing the weight of even the largest cruise ships in the world.

Passenger Ferries: Compared to cruise ships, passenger ferries tend to be smaller and lighter. While some ferry vessels can still weigh in the tens of thousands of tons, they generally do not approach the weight of a large cruise ship. Ferries prioritize efficient transportation over extensive onboard amenities and facilities.

Offshore Platforms: Offshore oil and gas platforms are colossal structures used for extraction in deep waters. These stationary facilities can weigh hundreds of thousands of tons due to their massive size and the materials used in their construction.

While the weight of cruise ships can be substantial, other types of vessels, such as tankers, cargo ships, naval carriers, and offshore platforms, often exceed them in terms of sheer tonnage. However, cruise ships stand out with their unique blend of passenger comforts, luxurious amenities, and extensive entertainment options.

It’s important to note that weight alone does not necessarily determine the value or capability of a vessel. Each type of ship serves a specific purpose and operates within different parameters. Cruise ships, with their mix of size, amenities, and passenger capacity, offer a distinctive experience that sets them apart from other large vessels on the water.

In conclusion, the weight of a cruise ship is influenced by a variety of factors. From the structural components that provide stability to the passengers and crew who add their own weight, every aspect contributes to the overall mass of these floating cities. Fuel and water, cargo, and the equipment and amenities onboard further contribute to the weight of the vessel.

While cruise ships are undeniably large, they are not always the heaviest vessels on the water. Tankers, cargo ships, naval carriers, and offshore platforms can often surpass them in terms of sheer tonnage. However, cruise ships stand out due to their exceptional passenger experience, luxurious amenities, and extensive entertainment options.

It is vital for cruise lines to carefully manage and distribute the weight of their ships to ensure stability, safety, and comfort for everyone on board. Balancing the weight of passengers, cargo, fuel, and equipment is a complex task that requires meticulous planning and expert engineering.

As the cruise industry continues to evolve, there is an increasing focus on optimizing efficiency, reducing environmental impact, and enhancing the onboard experience. Cruise lines are exploring innovative technologies and cleaner fuel sources to minimize the weight associated with fuel consumption and maximize sustainability.

So, the next time you marvel at the colossal size of a cruise ship, remember that its weight is the result of various elements working in harmony. From the sturdy structural components to the multitude of amenities and the diverse cargo it carries, the weight of a cruise ship is a testament to the complexity and engineering marvel of these floating wonders.

How Much Does a Cruise Ship Weigh?

By Alice Nichols

Cruise ships are a popular mode of travel for many people, as they provide a great way to explore the world while also having access to all sorts of amenities. But how much does a cruise ship actually weigh? It may surprise you to know that the answer is quite varied.

The Size of the Cruise Ship Matters – Generally speaking, the larger the cruise ship, the more it will weigh. A smaller cruise ship can range from 35,000 to 65,000 tons in weight, while larger ships can be upwards of 200,000 tons. This means that some of the largest cruise ships in operation could weigh as much as four or five times more than the smallest ones.

Material Matters Too – Another factor that determines a cruise ship’s weight is its material composition. Steel is one of the most common materials used in constructing cruise ships, and it typically weighs between 500 and 800 pounds per cubic foot (2.5-4 kg/m3). Aluminum is also commonly used in building these vessels, and it can weigh anywhere from 200 to 400 pounds per cubic foot (1-2 kg/m3).

Fuel and Cargo Are Important As Well – The amount of fuel and cargo on board a cruise ship will also affect its overall weight. For example, an average-sized vessel carrying about 20 tons of fuel can add an additional 4,000 tons to its overall weight. And depending on what kind of cargo—foodstuffs, supplies, etc.—a ship has on board at any given time can add anything from several thousand to several million pounds (1-4 million kg) to its total weight.

In Conclusion , a cruise ship’s exact weight will vary based on its size, material composition, fuel load and cargo load. Smaller vessels tend to weigh between 35,000 and 65,000 tons while larger vessels can reach upwards of 200 thousand tons or more depending on their contents. Knowing how much your particular cruise ship weighs can help you better plan your voyage and make sure you have enough space for everything you need onboard.

Conclusion: How much does a cruise ship weigh? The answer depends on its size, material composition, fuel load and cargo load but generally speaking smaller vessels range from 35-65 thousand tons while larger ones can be upwards of 200 thousand tons or more depending on their contents.

How Much Of A Cruise Ship Is Under Water?

Many new cruisers often ask the question, “How much of a cruise ship is underwater, and why don’t they sink ?” For me, it was a major curiosity until I got an answer. So, if you’re also one who wants to know the answer, you’re at the right place. 

Basically, the ship’s depth under the water depends on the size of the ship and the amount of load being carried. Generally, around 10% of the ship’s height, or approximately 30 feet for the biggest cruise ships and 20 feet for the smaller ships, is underwater, 

Sounds interesting, right? But wait, the science behind the ship floating is even more interesting, due to which they run seamlessly without being unstable. 

So get ready, my fellow cruisers. I’ve discussed all the things in this article that will help you clear your doubts. The next time you cruise, you’ll be happy to see the facts with your own eyes. So let’s get started. 

Table of Contents

Cruise Ship Weight, Length, and Height Statistics

Before understanding the depth at which a cruise ship sits, it’s important to learn about the cruise ship’s weight, length, and height statistics.

The 50 largest cruise ships in the world, including those from Royal Caribbean and Carnival Cruise Line, weigh over 100,000 gross tons.

Regarding height, the average Royal Caribbean Cruise Ship measures 14 decks (stories) high.

In terms of length, these ships are approximately 20% longer than the Titanic, with an average length of 325 meters.

You can also check out my comprehensive comparison of modern ships and the Titanic.

How Does A Cruise Float?

Cruise ships float above the water line and don’t sink because of the following factors:

1- Hull Shape And Design

The ship’s hull and design are the major reasons why it doesn’t sink. 

These U-shaped hulls push the water outward and downward, creating a buoyant force for the ship.

Not only that, but this massive hull also maximizes the water displacement, creating a lifting effect. A lot of modern cruise ships, including Royal Caribbean and Carnival Cruise Line, feature a V-shaped hull design to cut through the water efficiently.

Due to these hulls, the ship glides through the water with ease, maintaining stability and efficient floatation.

For physics lovers, let me explain with a principle. The hulls follow Archimedes’ principle, which states that the floating object is pushed up by a force equal to the weight of the liquid it displaces.

So yeah, now you must have a clear understanding of the science behind ship floatation and why it doesn’t sink.

How Deep Do Cruise Ships Sit In The Water? 

Generally speaking, the answer varies due to the ship’s size.

Smaller cruise ships tend to sit lower in the water than the larger ones. It’s because they have less buoyancy and are more susceptible to being swamped by waves.

Both ship’s design and operation play an important role in the depth at which a cruise ship sits in the water.

Cruise ships typically sit between 12-15 feet below sea level when fully loaded with cargo, fuel, and passengers. 

This depth helps the sea voyagers to stay stable while providing enough buoyancy for them to float.

However, it’s important to note that the depth of the cruise ship in the sea also depends on physical factors like rough seas and heavy load.

If the ship is sailing in rough seas, it may sit deeper in the water for increased stability. Likewise, for the heavy load, the depth of the ship will also be greater.

How To Measure The Depth At Which Ship Sit In The Water?

For measuring the depth at which a ship sits in the water, we look at the draft. 

The draft size varies from ship to ship depending on the vessel’s size, fuel, and ballast. 

Usually, cruise ships have a draft between 5 meters (16ft 5in) and 10 meters (32ft 10in).

The large cruise ships like Anthem of the Seas have a draft of 8.5 to 8.8 meters (about 28 feet). Likewise, the largest cruise ships, Royal Caribbean Oasis-class, have a draft of 9.3 meters (30ft 7in).

Smaller cruise ships typically have a draft of less than 7m (22ft 9in) so they can enter smaller ports.

Generally, the ship’s draft sizes are essential for determining the port the ship can enter. 

I’ve mentioned the two terms that you’ll often hear when it comes to measuring the depth at which a ship sits in the water.

1- Draft Marks

Draft marks are the major indicator of how deep the ship is sitting in the water. These marks are located at the bow and stern.

With these marks, one can easily assess the ship’s draft, which is the depth from the waterline to the lowest point of the hull.

Next time, I suggest you focus on these marks to learn how much the cruise ship on which you’re traveling is submerged in the water.

2- Load Line

The second way I discovered this was on my last cruise ship on Royal Caribbean when I was sailing on Icon Of the Seas. It’s called the Plimsoll mark or load line.

This line is present at the center of a ship’s side, which indicates the maximum safe draft. It was named after Samuel Plimsoll.

In actuality, this line sets the limit to which the vessel can be loaded. There’s a line passing through the circle highlighting this maximum point, with a ladder arrangement showing different drafts for specific conditions.

The letters on the mark (T for Tropical, S for Summer, and W for Winter) denote maximum drafts under certain conditions.

Amazingly, the S load line is used to prevent overloading, as sailing with this mark submerged is illegal.

The N and V markings represent the ship’s classification society, ensuring adherence to international standards. This load line helps measure the ship’s depth in the water, ensuring compliance with safety regulations.

Why Do Cruise Ships Have Flat Bottoms?

Cruise ships work on the principle of buoyancy given by Archimedes’ Principle. So, for this reason, they have flat bottoms for increased stability and fuel efficiency.

Flat bottoms are highly beneficial in providing a larger surface area, thus increasing stability in calm as well as in moderately rough seas.

Not only that, flat bottoms allow for better weight distribution, preventing the ship from rolling excessively.

The Physics of Water Displacement

If you don’t enjoy physics like my husband, feel free to move on to the next section. But if you really want to understand the concept of a ship underwater, I suggest you have a look at this section.

As I already mentioned, the cruise ship’s underwater size is based on the Archimedes Principle, which explains the relation between the weight of an object and the fluid it displaces.

To make it simpler in cruise ship terms, this principle states that the ship must displace an amount of water equal to its weight to maintain stability.

The Role Of Ship Stability

Stability is a major concern while designing cruise ships. Several measures are taken to keep the ship stable, especially in the rough seas.

But do you know the science behind the ship’s stability? It’s all due to the low center of gravity and high buoyancy.

For a ship to be stable, its center of gravity must be low, and its buoyancy must be high.

As mentioned earlier, the large ship hull design helps the ship to be more stable by distributing the weight of the ship over the larger area and allowing for a more significant amount of water displacement.

With all these factors, a stable vessel is designed to provide an enjoyable experience to passengers even in the rough seas.

Read more about cruise stability here.

Explanation Of Cruise Ship Design Features

How Much Water Does A Cruise Ship Hull Displace?

The amount of water displaced by a cruise ship’s hull follows Archimedes’ principle. According to this principle, the cruise ship displaces an amount of water equal to its own mass.

Let’s take an example of the largest cruise ship, Symphony of the Seas, which weighs approximately 228,000 tons and would displace 228,000 tons of water.

Now, you’ll have a clear understanding of how much water is displaced by the ship’s hull. Thanks to Archimedes’ Principle.

What Keeps a Cruise Ship From Tipping Over?

Cruise Ships are designed so efficiently that they are safe and stable.

A lot of people are curious to know why cruise ships don’t tip over, even if they’re so huge. 

So, the combination of a wide hull, low center of gravity, fuel, and ballast tanks filled with water maintains a great balance and keeps a cruise ship from tipping over in rough seas.

What Extra Steps Are Taken For Extra Stability In Rough Seas?

The cruise ship’s stability totally depends on the center of gravity. It’s kept low to keep the ship stable, but it can be moved up or down by adjusting weights within the vessel.

The most obvious is ballast water and fuel. In extreme cases and rough seas, cruise ship swimming pools could be drained to provide additional stability as the weight of so much water on the upper decks will make the center of gravity higher.

Most cruise ships have a mechanical stabilizing system, and some have bilge keels, which also help to limit the amount of roll.

How Many Decks Are Underwater on a Cruise Ship?

The number of underwater decks on a voyage depends on its size and type. 

However, cruise ships usually have one or two decks underwater, but passengers won’t find them as these decks are not named or numbered.

These are usually out of bounds for passengers as they contain various ship’s operational things and consist of hundreds of crew cabins to provide living and sleeping space for them.

So the next time you cruise, keep in mind that if you’re on Deck 1, you’re not the lowest on the ship. There are other decks under you.

The lower decks also need to house the following:

• Various engine and mechanical rooms
• Food storage units 
• Medical Center
• Crew-only social rooms

Do Cruise Ships Have Staterooms Underwater?

No, Cruise ships don’t offer underwater staterooms. However, there are cabins only for crew members to live and sleep in. 

These are quite small and windowless as compared to those for cruise guests.

So, if you’re planning to book the underwater cabins, forget it, as they are only limited to the onboard crew members.

Why Don’t Cruise Ships Have Underwater Viewing Areas?

At the beginning of my cruise journey, I also asked my husband why the cruise line doesn’t offer underwater viewing areas to let us see all the marine life and coral reefs as we sail through the ocean.

But later on, I got an answer by myself. There are several reasons why cruise ships don’t have underwater viewing areas.

• Strength: Glass is not as strong as steel, which is crucial for handling sea pressures.
• Utilization: Underwater decks serve mechanical and crew needs, making structural changes challenging.
• Safety Concerns: Adding viewing areas may compromise ship safety during accidents or pressure.
• Cleaning Challenges: Windowed areas would require frequent cleaning due to algae buildup.
• Maintenance Costs: Regular cleaning and maintenance would be costly for cruise lines.
• Practicality: 99% of the time, an underwater viewing area would show disturbed water.

What Parts of a Cruise Ship Are Underwater?

Now, after knowing the ship’s floating science and the depth at which it’s underwater, you must be thinking about the vessel parts underwater.

These parts include:

• Bulbous Bow: The front part of the ships have a bulbous bow, a big projection that sticks out and changes how the water moves along the side of the ship.
• Propellers:   At the stern, there are propellers designed to push through the water and move the ship forward or even backward in some cases.
• Hull: The U or V-shaped hulls displace large amounts of water, which increases the buoyancy force required to keep such large, heavy vessels floating.

How Much Water Does a Cruise Ship Need to Dock?

A cruise ship usually needs about 9 to 12 feet more than its draft to dock safely. 

Let’s suppose that a ship has a 30-foot draft; it requires water depths of at least 40 feet for safe sailing, accounting for its bouncing movement.

Where’s the Most Of the Cruise Ship Weight?

The majority of the ship’s weight is underwater to maintain the ship’s low center of gravity for extra stability in rough seas.

What’s On The Lowest Deck?

The lowest deck of the vessel, also known as orlop, it’s just below the cove balconies and contains essential components necessary for the ship’s operation including engine room. Also, it contains crew-only cabins for their living and sleep.

Final Words

Hopefully, now you have an answer to the question of how the cruise ship floats and its depth under the water.

Next time, you’ll enjoy your cruise even more after seeing all the above facts and science with your eyes.

Have a safe and enjoyable cruise.

How the Weight of a Cruise Ship is Calculated

The weight of a cruise ship is calculated using a number of different methods. The most common method is to use gross tonnage, deadweight tonnage, and lightship tonnage.

• Gross tonnage: Gross tonnage is a measure of the total volume of a ship. It is calculated by multiplying the ship’s length, breadth, and depth by a factor of 100. Gross tonnage is used to determine the amount of taxes and fees that a ship must pay.
• Deadweight tonnage: Deadweight tonnage is a measure of the weight of a ship’s cargo, fuel, and stores. It is calculated by subtracting the weight of the ship’s hull, machinery, and equipment from its gross tonnage. Deadweight tonnage is used to determine the maximum amount of cargo that a ship can carry.
• Lightship tonnage: Lightship tonnage is a measure of the weight of a ship without its cargo, fuel, and stores. It is calculated by subtracting the weight of the ship’s cargo, fuel, and stores from its gross tonnage. Lightship tonnage is used to determine the amount of ballast that a ship needs to carry in order to maintain its stability.

Examples of the Weight of Different Types of Cruise Ships

The following are some examples of the weight of different types of cruise ships:

• Ocean liner: An ocean liner is a large cruise ship that typically carries over 2,000 passengers. The weight of an ocean liner can range from 500,000 to 1,000,000 tons.
• River cruise ship: A river cruise ship is a smaller cruise ship that typically carries fewer than 1,000 passengers. The weight of a river cruise ship can range from 50,000 to 100,000 tons.
• Expedition cruise ship: An expedition cruise ship is a type of cruise ship that is designed for exploring remote destinations. The weight of an expedition cruise ship can range from 100,000 to 200,000 tons.

The weight of a cruise ship is a complex issue that is determined by a number of factors. The size of the ship, the number of passengers and crew, the type of ship, and the materials used in construction all play a role in determining the weight of a cruise ship.

By understanding the factors that affect the weight of a cruise ship, we can better understand the design and operation of these massive vessels.
