Valve co-founder Gabe Newell appears in the promotional video for Leviathan, the 111-meter Oceanco superyacht he owns.
Newell acquired the Dutch shipyard in 2025, and the vessel was delivered late that year.
At 364 feet long with a gross tonnage approaching 5,000 GT, Leviathan features diesel-electric hybrid propulsion, scientific laboratories, a professional dive center, medical facilities, and thoughtfully designed communal spaces.
