How Much Does a Cruise Ship Weigh (2026 Data)

Icon of the Seas is listed at 248,663¹ gross tons, a figure that sounds like a weight but is not one. Gross tonnage measures the enclosed volume of a ship. Loaded with fuel, water, stores and people, Icon of the Seas actually weighs 114,291¹ tons, less than half of its tonnage figure.¹

This page gives the weight of 114 ocean cruise ships that call at US ports, as their registry records show it, then follows what that weight costs to move: fuel per hour, per day and per passenger, what a new ship costs, what a ship earns in a day, and how many people are reported missing at sea.

How much does a cruise ship weigh?

Across the 114 ocean cruise ships with a usable weight record in the registry of ships calling at US ports, the median weight is 50,243 tons¹ and the mean 53,034 tons².¹ Those tons are displacement: the weight of the water a floating ship pushes aside, which equals the weight of the ship and everything aboard.

Gross tonnage is volume, displacement is weight

Gross tonnage is a unitless index of all enclosed spaces, set by the International Convention on Tonnage Measurement of Ships of 1969. It is the number printed in every ship fact sheet, and it is not a weight.¹ Displacement is the weight. Deadweight is the part of that weight a ship carries as load: fuel, fresh water, stores, passengers, crew and luggage. Subtract deadweight from displacement and what remains is the lightship, the empty ship itself.¹

The two measures move together. For the median ship the weight in tons is 0.516² of its gross tonnage, so halving the tonnage figure gives a rough weight.² The largest ships run lower: Icon of the Seas weighs 0.46² tons per gross ton, because a tall ship full of cabins and open decks encloses more space for each ton of steel.²

How much does the average cruise ship weigh?

The average depends on the fleet counted. Among ships that call at US ports the mean is 53,034 tons², a little above the median, because a handful of ships above 100,000² tons pull the average up.¹ Ships in the sample average 112,440² gross tons, with a median of 108,865², across the 169¹ ships that have a tonnage record.¹

How much does a cruise ship weigh in pounds?

The registry prints most weights in "tons" and some in "metric tons". A metric ton is 2,204.62 pounds and a long ton 2,240 pounds, so the median ship weighs 110.8 million² to 112.5 million² pounds depending on the ton used.² Either way, a typical large ship weighs about 110 million pounds. Icon of the Seas comes to 252.0 million² to 256.0 million² pounds.²

The biggest cruise ships

How much does the biggest cruise ship weigh?

Icon of the Seas is the heaviest ship in the US port registry sample at 114,291 tons¹ and, with Star of the Seas, the largest by volume at 248,663¹ gross tons.¹ It is 1,196.6¹ feet (364.7² meters) long and 219.3¹ feet across at its widest, and sits 29.5¹ feet deep in the water.¹ That is 23,381² gross tons more than Allure of the Seas, the largest ship of 2010.²

Among ships calling at US ports, Royal Caribbean International ships fill the first eight places. The largest ship of another line is MSC World America, delivered on March 27, 2025, at 216,638³ gross tons, 1,094³ feet long, with room for 6,762³ passengers and 2,138³ crew.³ Carnival Cruise Line's three largest ships each measure just over 180,000² gross tons.¹

Tonnage and weight rank the ships almost the same way, but not exactly. Harmony of the Seas and Symphony of the Seas are both recorded at 106,042¹ tons, more than Oasis of the Seas at 104,000¹, although Oasis encloses slightly less space.¹

Most of a big ship's weight is the ship itself. Icon of the Seas' empty hull, engines and fittings weigh 92,778² tons, 81.2%² of the total; the other 21,513¹ tons of deadweight is fuel, water, stores, luggage and people.¹²

How cruise ships got bigger

Ships built in the 2020s average 134,794¹ gross tons, 1.82² times the 73,912¹ of those built in the 1990s that still sail to US ports.¹² The largest ship of each decade grew too, from 138,194¹ gross tons in the 1990s to 248,663¹ in the 2020s.¹

Most ships still sit in the middle of the range. Of the 169 ships with a tonnage record, 61¹ measure 100,000 to 149,999 gross tons and 54¹ measure 50,000 to 99,999; only 9¹ pass 200,000.¹

Size depends heavily on the brand. Royal Caribbean International's ships average 156,731¹ gross tons, the most of any brand with three or more ships in the sample, while Silversea's small luxury ships average 34,218¹.¹ The smaller-ship brands (Silversea, Regent Seven Seas, Viking's ocean ships and Oceania) all stay below 50,000² on average.¹

Berths grew faster than the number of ships. Ocean cruise ships of the member lines of the main industry body held 2,020² lower berths each on average in 2018 and 2,116² in 2026, as 327⁴ ships shared 692,000⁴ berths.⁴²

Few cruise ships calling at US ports fly the US flag. Of the 184 ships with a flag in the registry sample, 86¹, or 46.7%², are registered in the Bahamas, followed by Malta with 24¹ and Panama with 21¹.¹ Only 5¹ fly the US flag.¹

How much fuel does a cruise ship use?

Moving 50,000² tons or more through the water takes a great deal of fuel, and the three largest cruise companies spent $3,629.9 million² on it in 2025.² The amount depends on whether it is counted per day across the year, per hour at sea, or per passenger.

How much fuel does a cruise ship use per day?

Across a whole year, including days in port and in dry dock, an average big-line ship burns 80.9² to 87.2² metric tons of fuel a day.² For Carnival Corporation in fiscal 2025 that is 84.6² metric tons (93.3² short tons) per ship per day, from 29.2⁵ metric tons per 1,000 berth-days and 2,898² berths per ship.⁵² At $610⁵ per metric ton, that is about $51,606² of fuel per ship each day.²

The companies' own quarterly figures put the totals in context. Royal Caribbean Group burned 439,000⁷ metric tons in the fourth quarter of 2025 at $667⁷ per ton and expects 1,762,000⁷ tons in 2026.⁷ Norwegian Cruise Line Holdings burned 253,000⁹ tons in the same quarter and expects 1,020,000⁹ tons in 2026, with fuel at 12.0%¹⁰ of its cruise operating expense in 2025.⁹¹⁰

How much fuel does a cruise ship use per hour?

Averaged over every hour of the year, a Carnival Corporation ship burns about 3.5² metric tons an hour.² Hours at sea burn more. For 201 passenger and cruise ships on voyages to, from and between European Union ports in 2025, the median ship burned 3.03² metric tons per hour at sea, or about 72.8² tons per 24 hours of sailing.¹¹ These figures include the fuel burned in those ports, so they somewhat overstate the burn while under way.

Norwegian Epic and Allure of the Seas are the two thirstiest ships in the set, at about 9² metric tons an hour, or about 217² tons a day of steady sailing.¹¹ Most ships burn far less: 72¹¹ of the 201 burn 2 to 3.99 tons an hour, and only 18¹¹, or 9.0%², burn 6 tons or more.¹¹² MSC World Europa burned 39,325¹¹ metric tons in total, as a very large ship that spent 5,790¹¹ hours at sea on EU voyages.¹¹ Per distance, the median ship burned 226² kilograms of fuel per nautical mile, while Allure of the Seas burned 592.5¹¹.¹¹

Fuel per passenger

Bigger ships spread their fuel over more people. Among large ships burning more than 10,000 metric tons in the year, the lowest burn per passenger per nautical mile was AIDAnova's 53.19¹¹ grams.¹¹ The six most efficient ships (AIDAnova, Arvia, Costa Toscana, AIDAcosma, Iona and Costa Smeralda) all run on liquefied natural gas.¹²¹³

Carnival Corporation's own totals show the same trend over time. Its ships burned 0.397² metric tons of fuel for every passenger carried in fiscal 2006 and 0.206² in fiscal 2025, a drop of 48.1%².²

How much fuel does a cruise ship hold?

No cruise line publishes the total tank capacity of its ships, so there is no official figure. The registry gives an upper bound: deadweight, the most a ship can carry of everything together. For Icon of the Seas that is 21,513¹ tons, for Queen Mary 2 19,190¹ tons and for Viking Star 3,640¹ tons, shared between fuel, water, stores and people.¹ Icon of the Seas runs on liquefied natural gas and carries two LNG tanks; the first one installed weighs 307²⁰ tons.²⁰

So is the industry burning more fuel or less? Per berth it is burning less, but the fleet keeps growing, and the answer depends on which of the two is counted.

Fuel use and fuel prices over time

Carnival Corporation burned 55.7² metric tons of fuel per 1,000 berth-days in fiscal 2006 and 29.2⁵ in fiscal 2025, 26.5² tons less, or about 48%².²⁵ Its total burn peaked at 3,395,000¹⁵ metric tons in fiscal 2011 and was 2.8 million⁵ in fiscal 2025, while its berth-days rose from 49.9 million² to 96.5 million⁵.¹⁶⁵

The price of each ton swings far more than the amount burned. Carnival Corporation paid $179¹⁴ per metric ton in fiscal 2003, $710¹⁶ in fiscal 2012, $283¹⁷ in fiscal 2016 and a peak of $830¹⁹ in fiscal 2022, before easing to $610⁵ in fiscal 2025.¹⁴⁵ The 2022 price was 1.36² times the 2025 price.²

Across the three largest companies the fuel bill for 2025 came to $3,629.9 million²: $1,808 million⁵ at Carnival Corporation, $1,146 million⁸ at Royal Caribbean Group and $675.9 million²² at Norwegian Cruise Line Holdings.² The bills fell sharply in 2020 and 2021, when ships sailed empty or not at all, and have been above 2019 levels since 2022.¹⁹²³²² Carnival Corporation's highest bill in the series was $2,381 million²⁴ in fiscal 2012, when fuel cost $710¹⁶ a ton; Royal Caribbean Group's pre-2020 high was $947.4 million²⁵ in 2014.²⁴²⁵

How much does it cost to buy a cruise ship?

Cruise lines do not publish the price of single ships, but order values give the scale. Norwegian Cruise Line Holdings' 13 ships on order carry combined contract prices of €18.3 billion¹⁰, about $21.5 billion¹⁰, or $1.65 billion² per ship.¹⁰² The 60 ships on the industry's order book from 2026 to 2037 are valued at $71 billion⁴, $1.18 billion² each, and the 8 ships due in 2026 at $6.6 billion⁴, $0.82 billion² each.⁴²

Paying for a ship takes years. Royal Caribbean Group had paid $1.0 billion⁸ in deposits on its $11.3 billion⁸ of ships on order at the end of 2025, and it arranged export-credit loans covering about 80% of the contract price of its fourth Icon-class ship, up to €2.1 billion⁸.⁸ That loan ceiling is a financing limit, not a published price. Carnival Corporation lists $11.9 billion² of remaining payments for seven ships under contract, spread over its fiscal years 2026 to 2031 and after; these are the payments still due, not the ships' prices.⁵²

How much does it cost to charter a cruise ship?

No cruise line publishes charter rates, so there is no official price list. What a ship earns in a normal day shows the order of magnitude. In 2025 an average Carnival Corporation ship brought in about $800,000² a day, a Royal Caribbean Group ship about $933,000² and a Norwegian Cruise Line Holdings ship about $845,000².² Over a 7-night sailing that is $5.6 million² to $6.5 million² of revenue per ship.²

Passengers at sea and safety

All that weight and fuel carries more people every year. Ocean cruise ships carried 37.2 million⁴ passengers in 2025, 1.25² times the 29.7 million⁴ of 2019 and about 19.6² times the 1.9 million⁴ of 1985 (early years count member lines only).⁴² The fleet that carries them is also growing: the industry's order book holds 60⁴ ships with 193,000⁴ lower berths through 2037.⁴ The collapse to 5.8 million⁴ in 2020 and 4.8 million⁴ in 2021 was the pause in cruising.

More passengers also means more reports of crime and people lost at sea. US law requires cruise lines to report serious incidents on ships that embark or disembark passengers in the United States, and the reports include missing US nationals.²⁶ Counted that way, the total number of cruise ship disappearances was 1²⁷ in the fourth quarter of 2025 and none in the first half of 2026.²⁷²⁸²⁹ The published quarterly summaries for the first three quarters of 2025 do not state the number of missing US nationals. The count covers only US nationals, not crew or passengers of other nationalities, so it is lower than the number of all people who go overboard.

In 2025, 182²⁷ incidents were reported across the four quarters, and sexual assault, including rape, made up 131²⁷ of them.²⁷ In the fourth quarter alone, 29²⁷ of the 44²⁷ reports were sexual crimes; the rest were 7²⁷ thefts over $10,000, 5²⁷ assaults with serious bodily injury, one suspicious death, one homicide and one missing US national.²⁷

By cruise line, the counts follow fleet size more than anything else. In the first half of 2026 Carnival Cruise Line ships had 31² reported incidents and Royal Caribbean ships 21², out of 93² in all; these are also the two largest fleets calling at US ports.²⁸²⁹¹

What the size means for the people on board and on shore

For a passenger, the weight of the ship shows up in the fare as fuel. At Carnival Corporation each passenger carried in fiscal 2025 accounted for 0.206² metric tons of fuel, worth about $126² at $610⁵ a ton.²⁵ Each new berth on the industry's order book costs about $368,000² to build.²

On shore, cruise ships support jobs in every state, not only in the ports. Florida had 172,100³³ cruise-supported jobs in 2024, far ahead of California with 24,900³³ and Texas with 24,500³³.³³

Conclusions

1. The famous tonnage figure is not a weight. A cruise ship calling at US ports weighs a median 50,243 tons, and its weight is typically 0.516 times its gross tonnage.¹²
2. Ships keep getting bigger while each berth burns less. Ships from the 2020s average 1.82 times the gross tonnage of 1990s ships, while Carnival Corporation's fuel per 1,000 berth-days fell from 55.7 to 29.2 metric tons.¹⁵²
3. Fuel is a daily bill. An average big-line ship burns about 85 metric tons a day, worth about $51,606 at Carnival Corporation's 2025 price, and the three largest companies spent $3,629.9 million on fuel in 2025.²⁵
4. A new ship costs about as much as the largest company's yearly fuel bill. An average new ship on order at Norwegian Cruise Line Holdings ($1.65 billion) costs about as much as the largest company, Carnival Corporation, spent on fuel in fiscal 2025 ($1,808 million).¹⁰⁵
