Oceanco delivered the 111-metre (364ft) superyacht Leviathan on November 13, 2025, to American entrepreneur Gabe Newell, co-founder of Valve Corporation, the company behind the gaming platform Steam. The handover adds another 100-metre-plus project to a Dutch yard's 2025 tally, in a year the superyacht industry has repeatedly matched with size and order-book records.

What is confirmed about Leviathan
Leviathan measures 111 metres (364ft) and was delivered by Oceanco on November 13, 2025, according to the report published by Italian trade press. That source does not detail gross tonnage (GT), cabin count, the exterior or interior design studio, or the propulsion system — details a yard typically releases in a separate press kit when it chooses to. Where a figure was not disclosed, we say so rather than estimate it.
What is verifiable is the essential shape of any superyacht delivery: length, date, and the vessel's new owner. For a trade story, those three points are enough to place Leviathan among the year's largest confirmed handovers.
Who owns her
Leviathan was delivered to Gabe Newell, co-founder of Valve Corporation — the American video-game company behind titles such as Half-Life and Counter-Strike and, most visibly, the digital-distribution platform Steam, one of the largest PC gaming storefronts in the world. That ownership detail comes from the delivery announcement itself; no source reviewed for this article carries a statement from the owner about the yacht, and none is attributed to him here.
A record week for Oceanco
Seven days after Leviathan, Oceanco delivered a second 111-metre superyacht: DreAMBoat, a custom 4,550GT project, on November 20, 2025. Two vessels of identical length leaving the same yard within a single week is unusual for the industry — most superyacht builders deliver at most one project of that scale per month, given the outfitting and sea-trial time a hull over 100 metres requires. We are covering DreAMBoat's own build timeline in a dedicated article.
2025's run of 100-metre-plus yachts
2025 has strung together a notable run of milestones in the 100-metre class. In May, Feadship floated out its 100-metre Project 824 after 20 months of outfitting — first reported by trade press. That same month, the 122-metre Lürssen-built Kismet won Motor Yacht of the Year at the World Superyacht Awards 2025 in Venice. With Leviathan and DreAMBoat, November reinforces that pattern of major projects reaching completion throughout the year.
| Yacht | Builder | Length | 2025 milestone | Date |
|---|---|---|---|---|
| Leviathan | Oceanco | 111m | Delivery | Nov 13 |
| DreAMBoat | Oceanco | 111m | Delivery | Nov 20 |
| Project 824 | Feadship | 100m | Float-out | May 9 |
| Kismet | Lürssen | 122m | Named Motor Yacht of the Year (World Superyacht Awards) | May 3 |
What this says about the industry
The cluster of large-scale completions in 2025 tracks what builders themselves have been reporting in their own results: Sanlorenzo, for instance, closed nine-month 2025 with a record EUR 1.7 billion backlog, driven largely by its superyacht segment. Ferretti Group, another major Italian group, closed the same period on a high note too, as we cover in Ferretti: Backlog Up 12.9% as the Superyacht Segment Grows 29.5%. None of the sources reviewed for this article discloses a sale price for Leviathan or DreAMBoat — Oceanco, like most custom builders, does not publish individual project values.
For the international charter market, deliveries like these gradually widen the available fleet above 100 metres, a category still limited to a small handful of yards worldwide — Oceanco, Feadship and Lürssen among the most active in it during 2025. Readers tracking that segment can browse the fleet available for charter at voguer.yachts; for boat rental on Brazil's own coastline, at a very different scale, the domestic catalogue is at voguer.com.br.
The season was also shaped by events outside the industry's control: in October, Hurricane Melissa struck Jamaica as one of the strongest Atlantic storms on record, redrawing Caribbean charter itineraries in the same weeks yards like Oceanco were closing out their annual delivery schedules.

Who owns Leviathan? Gabe Newell, co-founder of Valve Corporation, the American video-game company known for the Steam platform and titles such as Half-Life and Counter-Strike.

What are Leviathan's full specifications? Available sources confirm her length (111 metres/364ft) and delivery date (November 13, 2025). Gross tonnage, cabin count, design studios and propulsion type were not disclosed in the sources reviewed for this article — we state that gap rather than estimate the figures.
Did Oceanco deliver another yacht around the same time? Yes. Seven days after Leviathan, on November 20, 2025, Oceanco delivered DreAMBoat, another custom 111-metre superyacht at 4,550GT. Two deliveries of identical length in the same week is a rare occurrence in the superyacht industry.
What other major yachts marked 2025? In May, Feadship floated out the 100-metre Project 824 after 20 months of outfitting. That same month, the 122-metre Lürssen-built Kismet was named Motor Yacht of the Year at the World Superyacht Awards 2025 in Venice.
What did Leviathan sell for? That was not disclosed. Oceanco, like most builders of custom vessels, does not publish sale values for individual projects delivered to private clients.
Will Leviathan be available for charter? The sources reviewed for this article do not say whether Leviathan will enter the charter market. Recently delivered yachts often take months before an owner decides whether to offer them for charter at all, and many never do.
How can I follow future superyacht deliveries? This editorial section covers deliveries, launches and financial results from the yacht industry based on verifiable sources, whenever a builder or trade outlet confirms the information. Our coverage of DreAMBoat, delivered days after Leviathan, follows in its own article.
