Gabe Newell, the magnate behind Valve and the ubiquitous Steam platform, has taken delivery of the Leviathan, a colossal 364-foot Oceanco-built superyacht. The vessel, described as a "gigayacht," represents a radical departure from traditional superyacht concepts, integrating high-end living with functionality and a focus on community and innovation. Newell acquired the Dutch shipyard Oceanco in April 2025, making the Leviathan the first major build completed under his ownership.
The yacht’s interior, designed by Mark Berryman, eschews conventional guest-crew separation. Instead, it promotes a communal atmosphere, with spaces like a gaming lounge, a basketball court, and the sun deck accessible to both guests and crew. A substantial communal dining area can accommodate up to 54 people, reflecting Newell’s vision of the yacht as a shared community space. This philosophy extends to the inclusion of a 3-D printing workshop, intended for the crew to create spare or replacement parts, underscoring a commitment to maintainability and long-term operational capability.

A Hub for Innovation and Exploration
Beyond its recreational amenities, the Leviathan is equipped as a versatile platform for both work and play. Its design incorporates elements for scientific research, with one of Newell's other vessels, the "Limiting Factor," a research ship, being part of his broader "Inkfish" fleet. The Leviathan itself is slated to support marine research and explore remote ocean regions, contributing to scientific discovery.
Key features highlight the yacht’s advanced nature:
Extensive Cabling: Approximately 280 miles of cabling powers the vessel's numerous systems, including a full onboard hospital, a submarine garage, and two gyms.
Entertainment Suite: A dedicated cinema, a gaming lounge with 15 high-performance gaming stations and two racing simulators, and a dive store are among the leisure facilities.
Advanced Systems: The yacht includes a dedicated toy garage stocked with jet skis and a submarine, alongside a separate drinks pantry adjacent to the main kitchen, demonstrating a meticulous attention to detail for daily living.
A New Era for Oceanco
Newell's acquisition of Oceanco was not driven by profit, but by a desire to foster collaboration and innovation within the luxury shipbuilding sector. He worked closely with the Oceanco team, naval architects Lateral Naval Architects, and Y.CO throughout the design and construction process, involving thousands of designers and engineers. This hands-on approach signifies a new direction for the shipyard, known for producing a limited number of highly complex projects annually.

The Leviathan's construction emphasizes durable materials and practical details over high-gloss finishes, a deliberate choice for longevity and ease of maintenance. Sea trials have rigorously tested its performance, efficiency, and comfort, ensuring it meets Newell’s vision for a capable, long-range operational base.
Background: From Charter to Shipyard Owner
Gabe Newell’s journey into superyacht ownership began unexpectedly. A reluctant charter of a superyacht for his ex-wife sparked an intense appreciation for the experience, leading to the acquisition of a fleet of luxury vessels. This fascination culminated in his purchase of Oceanco, a shipyard renowned for its sophisticated builds. The Leviathan, commissioned from this very shipyard, stands as a testament to his commitment to pushing the boundaries of what a private vessel can be, blending cutting-edge technology with a unique philosophy of shared experience and scientific pursuit.
