A history of larger ships.
One question, several record books. Follow the measurements that changed maritime scale.
A curated historical timeline, not a complete register of every successor or a continuously updated record certification. Source dates and category boundaries are stated for each milestone.
Length: from iron steamships to supertankers
Selected milestones in hull length. These are not an uninterrupted succession of every record holder. Dates refer to the event stated, and later rebuilds can change a ship’s dimensions.
- 1858 · launch
Great Eastern ↗
About 211 mGreat Eastern made a dramatic jump in scale. Its sideways launch on the Thames illustrates how the ship exceeded the practical limits of its building site. The Brunel Museum describes its length in rounded feet; the profile records the commonly reported metric length.
- 1976 · delivery
Batillus ↗
414.22 mBatillus represents the French supertanker era, when hulls over 400 metres long were built to carry crude oil. This is an era milestone, not a claim that Batillus held every category of size record.
- 1980–1981 · enlargement
Seawise Giant ↗
458.45 mSeawise Giant’s enlarged hull became the lasting reference for ship length. The vessel was originally delivered in 1979; Lloyd’s Register Foundation dates the enlargement to 1980, while other accounts place its return to service in 1981. It was dismantled at Alang in 2010.
Gross tonnage: a different kind of record
GT is a dimensionless index of enclosed volume. These entries distinguish the overall ship record from passenger-ship milestones. Historical GRT is not inserted into this series as if it were modern GT.
- 2009 · cruise milestone
Oasis of the Seas ↗
About 225,000 GT at deliveryOasis of the Seas established a new scale for cruise vessels. The builder gives a rounded 225,000 GT figure. This dated figure is kept separate from the directory’s later vessel particulars.
- 2014 · overall ship record
Pioneering Spirit ↗
403,342 GTGuinness dates the gross-tonnage record to November 2014. The broad construction vessel shows why a shorter ship can outrank a longer tanker by enclosed volume. Its operational offshore work began later.
- 2022 · cruise milestone
Wonder of the Seas ↗
New cruise record at deliveryWonder of the Seas entered the fleet as the largest cruise ship of its time. That passenger-ship title did not displace Pioneering Spirit’s overall gross-tonnage record.
- 2024 · cruise milestone
Icon of the Seas ↗
Icon-class passenger scaleIcon’s inaugural voyage in January 2024 marked another increase in cruise-ship scale. Published class-level and vessel-specific tonnage figures differ; the profile identifies the source used for the directory ranking.
Cargo: slots and tonnes are separate tracks
Container capacity is shown in TEU. Deadweight is shown in tonnes and includes cargo, fuel, stores and other variable loads. Neither can be substituted for the other.
- 1980–1981 · deadweight milestone
Seawise Giant ↗
564,763 tonnes DWTGuinness records this deadweight for the enlarged tanker. It describes carrying ability, not the empty ship’s weight and not the quantity of oil carried on every voyage.
- 2011 · ore-carrier milestone
Ore Brasil ↗
About 400,000 tonnes capacityVale Brasil introduced a new scale of dedicated ore transport for the Brazil–Asia trade. This is an ore-carrier milestone; it is not a claim to exceed Seawise Giant’s deadweight.
- 2019 · container record
MSC Gülsün ↗
23,756 TEUMSC’s first-voyage report identifies a record nominal capacity. Cargo arrangement and width helped raise the slot count within a roughly 400 metre hull.
- 2021 · container record
Ever Ace ↗
23,992 TEUECT welcomed Ever Ace as the world’s largest container vessel in September 2021. This is nominal capacity, distinct from a record for containers actually loaded on a particular sailing.
- 2023 build · documented in 2025
MSC Irina ↗
24,346 TEUThe Vizhinjam port operator’s June 2025 report documents MSC Irina at 24,346 TEU and describes it as the largest by container capacity. The date of that report is not presented as its delivery date.
