Oceanco’s 111m Superyacht Leviathan: A Bold Step Toward the Future of Yachting
The new Oceanco yacht Leviathan is more than just another superyacht — it’s a statement of intent. Measuring 111 meters, this hybrid diesel-electric yacht is built around three pillars: innovation, sustainability, and human-centered design.
Unveiled in 2025 and previously known as Project Y722, Leviathan signals a new direction for Oceanco and for the next generation of large yachts.

Design and Engineering: Purpose Over Tradition
Created in collaboration with Lateral Naval Architects, the Leviathan’s exterior is powerful yet refined. The design by De Voogt Naval Architects rejects traditional ornamentation in favor of clean lines and a monochrome palette, setting a calm and confident tone.
Inside, Mark Berryman Design delivers an interior that feels serene and understated. Expect stone surfaces, glass walls, and natural materials—a deliberate departure from glossy wood finishes. Everything aboard feels tactile, purposeful, and grounded.
Hybrid Power and Environmental Innovation
One of the standout features of Leviathan is her diesel-electric hybrid propulsion. This advanced system allows for quieter operation, lower emissions, and improved fuel efficiency.
- Other eco-conscious innovations include:
- Battery energy storage for silent cruising
- Advanced wastewater treatment meeting strict global standards
- Sustainable materials, such as composite decks and alternative woods
- Oceanco’s goal is clear: to build a large yacht that’s future-ready, both technologically and environmentally.
Built Around People, Not Just Luxury
- Unlike many superyachts, Leviathan was designed with extensive input from her crew and owner from the earliest stages. That collaboration led to features like:
- Wellness areas for crew and guests
- Optimized workspaces that enhance efficiency and comfort
- Flexible living zones that adapt to different moods and occasions
- The message from Oceanco is simple: luxury isn’t just about opulence—it’s about how people feel onboard.

A Yacht With a Purpose
Reports suggest that Leviathan may also support research and exploration missions, combining comfort with capability. Her design reflects a belief that superyachts can have a positive purpose, beyond recreation — supporting marine research and sustainable innovation.
Interestingly, the names of more than 2,000 craftspeople involved in the yacht’s construction are etched into the vessel — a fitting tribute to the human hands behind this technological marvel.
Ownership and Legacy
Her owner is Gabe Newell, co-founder of Valve. The choice aligns with his known passion for technology and meaningful design.
Whether or not the rumors are true, Leviathan represents a broader shift: a new era of yachts that balance power, beauty, and purpose.
Newell owns a fleet of superyachts, including the Oceanco yacht DRAAK, the Lurssen yacht ROCINANTE, DAGON, HYDRA, and support vessel GAME CHANGER.
