Gabe Newell’s Superyacht: 5 Bold Ideas Behind Leviathan

Have you ever geeked out wondering how a superyacht could be more like a high-tech lab and less like a floating palace? The Gabe Newell Superyacht, Leviathan, is packed with bold ideas for life at sea, and it’s a masterclass in purpose-driven design.

This isn’t just about luxury. It’s about smart thinking.

We’re going to break down five of the coolest features that make this yacht a true visionary project. So, grab a drink, and let’s check out how luxury meets real-world function.

The 111-meter Superyacht “Leviathan” Delivered by Oceanco

Leviathan, at a massive 111 meters (about 364 feet) and with a gross tonnage of nearly 5,000 GT, is a sight to behold. Dutch shipyard Oceanco handed her over after a meticulous building process, a joint effort with designers and engineers known for pushing boundaries.

The project, formerly known as Y722, is one of the largest vessels ever built by the shipyard and reflects a forward-thinking philosophy.

Successful Sea Trials

Before any champagne bottles were popped, the superyacht had to prove itself in sea trials off the coast of Stellendam, Netherlands. These tests are intense, pushing the 111-meter vessel through open water while engineers measure everything from speed and maneuverability to noise and vibration levels.

Leviathan passed with flying colors. In fact, Oceanco’s CEO, Marcel Onkenhout, called it their “most comfortable yacht ever designed, built and delivered.”

Inside the main staircase, there’s a cool tribute to the build: a glass panel engraved with the names of more than 2,000 people who brought this beast to life. It’s a powerful reminder that this massive piece of engineering is the result of human collaboration.

Diesel-Electric Propulsion System

Forget noisy, gas-guzzling engines. Leviathan runs on a sophisticated diesel-electric propulsion system, a hallmark of modern marine engineering. Instead of diesel engines turning the propellers directly, they generate electricity that powers electric motors.

This setup, developed with partners like Lateral Naval Architects, is part of what they call an “E-Hybrid” system. It’s designed for efficiency, reducing fuel consumption and cutting emissions to meet the stringent IMO Tier III standards, which demand a nitrogen oxide (NOx) reduction of over 70% compared to previous regulations.

The system also includes a massive battery pack that allows the yacht to operate in near silence for hours without burning any fuel at all. This is perfect for quiet nights at anchor or navigating environmentally sensitive areas.

The green tech doesn’t stop there. An advanced wastewater treatment unit ensures every drop is cleaned to high environmental standards before it returns to the sea.

Human-Centric Design Approach

From day one, the focus of this build was on people. The designers aimed to create spaces that were incredibly comfortable for guests and highly efficient for the crew. Gabe Newell was deeply involved, working directly with Oceanco to think through every aspect of life on board.

The crew’s input was invaluable. Many users on forums like Reddit often point out how yacht designs can look amazing but be impractical for daily work. On Leviathan, crew feedback led to real changes, from the height of a chair to the placement of light switches, ensuring the layout is guided by ergonomics.

The yacht masterfully blends different functions. It has spaces that support scientific research right alongside lounges designed for relaxation after a long day. This approach makes sure the yacht is not just a vessel, but a highly functional and comfortable ecosystem at sea.

Collaboration for Operational Efficiency and Crew Wellbeing

The secret sauce behind Leviathan? Teamwork. Gabe, his team, the crew, and the builders all worked together in a way that’s pretty rare in the superyacht world. Even the wildest design ideas were put on the table, proving that an open, collaborative process can lead to incredible innovation.

Owner, Crew, and Builders Collaboration

That glass panel with over 2,000 names is more than just art, it’s a symbol of a deep collaboration. Oceanco, Lateral Naval Architects, and Mark Berryman Design held regular meetings with crew members at every stage of the build.

This meant real-world feedback directly shaped the yacht’s functionality. A chef could point out an inefficient counter placement, and the builders would change it. This open-door policy ensured that the operational flow was as smooth as possible.

The owner’s goal was to create a working ecosystem where hospitality and scientific labs could coexist seamlessly. This required a level of teamwork that went far beyond the traditional build process.

Praise from Gabe Newell for Oceanco

Gabe Newell had high praise for Oceanco, calling the building process “enjoyable, professional, and creative.” This makes perfect sense when you think about his background at Valve, a company famous for its flat, non-traditional corporate structure. He brought a software developer’s mindset to the project.

He treated the process like tuning a massive game server, welcoming “bugs and fixes” from the start. In shipbuilding, where changes are typically expensive and difficult, this iterative approach was a huge shift. Oceanco’s willingness to embrace it was key to the project’s success.

If you’re looking to become a game streamer, you know how important it is to have the right setup and a team that supports your vision. That same spirit of openness and partnership turned a bold vision into a reality on the water.

Unusual Design Requests Embraced by Oceanco

So, what happens when a tech visionary asks a shipyard to throw out the rulebook? Oceanco leaned in. The builders took some of Gabe Newell’s unconventional ideas and made them standout features of Leviathan.

• Function Over Frills: Instead of focusing on flashy, purely decorative elements, every design choice was driven by real-world purpose and teamwork.
• Smart Materials: They ditched hard-to-maintain materials in favor of modern composites to cut down on cleaning and repairs, which means no more endless varnishing for the crew.
• A Floating Lab: The yacht includes dedicated spaces designed for scientific research and experiments, turning it into a working lab at sea.
• Crew-First Layouts: Crew comfort was just as important as owner comfort. Rooms were placed strategically to reduce transit time and make daily tasks more efficient.

Design and Architecture

Oceanco handled Leviathan’s sleek exterior lines, while Mark Berryman Design crafted the interiors. The result is a yacht filled with open spaces perfect for science talks, collaborative projects, or just kicking back for a game session. Get ready to see how these choices break all the old rules.

Naval Architecture by Oceanco and Lateral Naval Architects

The technical foundation of Leviathan, known as project OCEANCO Y722, was a joint effort between Oceanco and Lateral Naval Architects. Their work on the naval architecture pushed the limits of modern yacht design. They developed a smart hull that enhances both stability and comfort, especially in rough seas.

This isn’t just about looking good. The hydrodynamic shape of the hull is designed to reduce drag, which directly contributes to better fuel efficiency. When combined with the diesel-electric propulsion system, it creates a fully integrated and highly efficient vessel. It’s a perfect example of how top minds in marine engineering can create something truly special.

Exterior Design by Oceanco, Interiors by Mark Berryman

On the outside, Oceanco opted for composite materials for surfaces like decks and handrails. This is a smart move that reduces the maintenance nightmare caused by constant exposure to sun and saltwater. The superstructure also features massive, full-height glass walls, creating stunning panoramic views from almost anywhere on board.

Inside, Mark Berryman, famous for his work on the 136-meter Lürssen yacht *Flying Fox*, brought his signature touch. His philosophy is all about creating a “home away from home” atmosphere with clean lines and natural materials. For Leviathan, he chose durable surfaces like honed stone, which doesn’t show smudges, and natural wool carpets that are soft, stain-resistant, and even help dampen sound.

Emphasis on Team Building and Scientific Work

Gabe Newell’s vision for Leviathan was for it to be more than just a pleasure craft. It’s designed to be a platform where crew, guests, and scientists can collaborate on meaningful projects. The layout features large, open rooms that are perfect for teamwork, allowing groups to gather easily or break off into smaller teams.

A crucial piece of technology making this possible is the yacht’s advanced connectivity. It’s equipped with a system like **Starlink Maritime**, which provides high-speed, low-latency internet even in the middle of the ocean. Offering download speeds that can reach up to 220 Mbps or more, it’s powerful enough for transferring large scientific datasets or, of course, a lag-free gaming session.

Innovative Technologies and Unique Layout

Leviathan is a showcase of smart engineering, swapping out traditional materials for advanced, long-lasting alternatives that make life easier for the crew. Every room is designed with a clear purpose, blending scientific function with genuine comfort in a way that is truly impressive.

Replacement of High-Maintenance Materials with Composite Alternatives

Anyone who has worked on a yacht knows the pain of maintaining traditional teak decks and steel handrails. They take a constant beating from the elements. On Leviathan, these high-maintenance materials were replaced with modern **composite alternatives**.

This means the crew spends less time sanding, oiling, and fixing, and more time focused on the mission of the vessel. Where you would typically find heavy metal, you’ll see full-height glass bulkheads. These advanced composites are not only lighter, which helps with fuel efficiency, but they also withstand harsh marine environments far better, looking great year after year with minimal upkeep.

Purposeful Yacht Operation

Leviathan isn’t designed to just sit in a marina, it’s built for action. Every aspect of its design supports real missions, from scientific research to long-range exploration. The layout is optimized for both focused work and collaborative play.

Gabe Newell wanted a vessel that was more than just luxurious, he needed it to be functional. The crew operates in spaces designed for comfort and efficiency on long voyages. The diesel-electric system isn’t just for show, it significantly reduces the yacht’s environmental footprint and extends its operational range, making it a sustainable and adaptable platform for missions at sea.

If you’re curious about taking the helm yourself one day, you can always learn to sail a yacht and get a taste of life on the water.
