Do you remember that feeling, the chills that ran through your body when you first sighted a cruise ship? The experience is grand.


The cruise ship is massive but still floats away in the waters with so much ease that you will be left wondering if it is that heavy.

The first question on your mind may be, how much does a cruise ship weigh with such an enormous size?

Cruise ships are remarkable feats of modern engineering. With some cruise ships being as high as 20 stories, with a length of about four football pitches, it is beyond what the average man can comprehend.

No joke, cruise ships are objects of immense weight but still perfectly buoyant enough to cut through those ocean waves and arrive at their destination. So, how much does a cruise ship weigh for this mammoth of engineering?

I could tell you the approximate weight of a cruise ship right now, but you’ll be wondering what makes it so heavy.

So, I will answer the question in your mind concerning its weight; but I will also enlighten you on just what and what takes up that weight.

To stay afloat, cruise ships need to displace a certain volume of water. You can also paraphrase the question, “How much does a cruise ship weigh?” How much water does a cruise ship displace? Maybe you have heard of the theory of displacement in elementary physics?

It is simple. The weight of the volume of water displaced is its weight. Hold on. We cannot measure the weight of the water displaced, and that would be an extremely futile task.

Massive passenger cruise ships can sit a little below 10 meters below the ocean’s surface. With this geometry, they can cut through ocean waters much more easily than smaller ships, making forward navigation easier for their immense size.

So, at this immense size, how much does a cruise ship weigh?

Parts of a cruise ship

The width, length, and height of a cruise ship all help provide the cruise ship with enough buoyancy by displacing enough water in the ocean.

Now, to fully understand the cruise ship’s weight, let us look at some parts of the cruise ship.

  • Aft: This is the area close to the stern of the ship in the rear.
  •  Bow: This is the front of the ship as it approaches.
  • Bridge: This ship area is usually located in the bow section. For ease of vessel management, it is the section that houses the captain and the control crew.
  • Cabin: Some call it a stateroom. The cabin is where passengers and guests stay, and it is your private room onboard the vessel.
  • Decks: This refers to the different floor levels of the ship. Now you know when they say lower decks or upper decks. They are analogous to the floor in a building, like the first floor and the last floor.
  • Gallery: This is where you have the ship’s kitchen.
  • Hull: This is the ship’s main body. It stretches both beneath and above the surface of the ocean.
  • Lido deck: What is a cruise ship without its pools, casinos, restaurants, bars, gyms, and other leisure amenities meant to entertain the guests to satisfaction? All these items are located on the lido deck.
  • Port: If you are facing the ship’s bow, the port is on the left side of the ship.
  • Starboard: When facing the ship’s bow, the right side is called the starboard. Let’s continue below.

These are just an overview of what makes up the cruise. With the parts mentioned above, you should begin to understand what makes up the weight of the cruise ship.

Relationship between space and weight of a cruise ship

Cruise ships could have several cabins ranging from a few hundred to thousands of passengers to accommodate thousands of passengers.

To get a picture of how much space these cruise ships have despite having many passengers, let us look at the passenger-to-space ratio.

This ratio is the enclosed space for a single passenger, measured in cubic feet. The ratio will also give you a rough estimate of how much a cruise ship weighs and the space available.

If a ship is rated at 50,000 GT (gross tonnage) and has a capacity for 2000 passengers, that means that each passenger will have a space of 25 cubic feet (50000/2000).

A higher ratio may be obtained by having larger public areas than the cabins. The larger cruise ships give the guests the luxury of space.

Heaviest cruise ships in the world

To further answer the burning question, how much does a cruise ship weigh? Let us see the gross tonnage of the top five largest cruise ships in the world.

  1. Symphony of the Seas: This cruise ship has an immense weight of 228,021 gross tons. This makes it the largest passenger cruise ship in the world.
  2. Harmony of the Seas: With a gross tonnage of 227,500, this cruise ship, manufactured in 2016, comes second on the list of the largest cruise ships in the world.
  3. Allure of the Seas: Falling behind the Harmony of the Seas by a few gross tons, the capacity of this cruise ship comes in at 225,282 gross tons. It has a passenger capacity of 5,400.
  4. Oasis of the Seas: This cruise has a similar weight to the Allure of the Seas, and it weighs in at about 225,282 gross tons.
  5. Costa Smeralda: This cruise ship has a capacity of 185,000 gross tons, which is slightly bigger than the sixth-largest cruise ship in the world, the P & O Lona, which weighs in at 184,700 gross tons.

Unit for measuring the weight of a cruise ship

Gross registered tons have been the benchmark unit for calculating the weight of cruise ships. How much does a cruise ship weigh? This question more or less refers to the gross tonnage of the ship.

Gross registered tons are more or less derived from space. A hundred cubic feet of enclosed space on a cruise ship makes one gross registered ton.

The Symphony of the Seas has been the largest cruise ship in the world since 2018, dethroning the Harmony of the Seas, which had earlier held the title of the world’s largest cruise ship since 2016.

If your little kid asks you, how much does a cruise ship weigh? A trip to sight the Symphony of the seas is sure to get his senses rolling.

Vessels weighing in at over 100,000 gross tons are being built. This completely eclipses the unlucky Titanic, which came to about 50,000 gross tons.

Relationship between weight and size of a cruise ship

The bigger the cruise ship, the more passengers it can accommodate, the heavier it will get. The bigger it is, the more room you have for more convenience, relaxation, and even privacy.

However, passengers on major cruise ships must wait hours to disembark from these vessels. The size will also provide a rough answer to the question of how much does a cruise ship weigh?.

With excellent dining, entertainment, and leisure options, cruise ships are perfect to be aboard. If you have the intention to develop your relationship with your family or others, they are the best means of transportation.

Everything is a matter of relaxation and pleasure.


So if you always ask yourself, how much does a cruise ship weigh? You can get one and put it on the scale. It is impossible to do that. I’m just kidding.

What if you could do something like that? I’m just giving it some thought. Nevertheless, cruise ships weigh more than 100,000 gross tons and more, with the biggest weighing more than 200,000 gross tons.
