Oceanco owner Gabe Newell’s $650 million fleet turns heads in Poole Harbour en route to the Monaco Yacht Show, while Leviathan’s 15-station gaming room and laboratory are matched by support vessel Draak’s dive center and hyperbaric chamber. Gabe Newell’s supremely spectacular fleet, featuring the 364-foot Leviathan and the 305-foot Draak, has been spotted together in Britain. The superyachts entered Poole Harbour early on August 23, 2026, after cruising together in Norway earlier in the month. They will be the stars of the upcoming 35th Monaco Yacht Show, which is less than a month away and runs from September 23 to 26, 2026. The Oceanco beauties are touted as being among the Monaco Yacht Show’s biggest yachts, with Leviathan taking the top spot at 364 feet.
With a combined length of 669 feet, neither vessel could be accommodated inside the smaller leisure marina at Poole Harbour. Instead, the gigantic vessels were berthed along South Quay, the Port of Poole’s secure commercial berth, where such giants sleep in peace. This could be a logistical stop, as Poole offers several practical advantages, including restricted access, 24-hour security, craneage and helicopter landing options.
Draak is the support vessel serving the futuristic, science-focused mothership, which was spotted in Poole in November 2025, immediately after Oceanco delivered it. On that occasion, too, Leviathan was berthed at South Quay, according to The Sun.
The superyacht is a surefire head-turner, with diesel-electric propulsion, a 5.5 MWh battery installation that can operate its hotel systems for up to 10 hours, and a nearly 33-foot pool that doubles as a social space for everyone aboard. The luxury vessel sleeps 12 guests and as many as 43 crew. Her luxe amenities include a basketball court, sun deck, hot tub, gaming room with 15 stations and two racing simulators. Unlike other pleasure craft, Leviathan boasts a series of unconventional additions, including a soundproofed audiovisual studio large enough for a drum kit. In keeping with the Valve billionaire’s love of working even in the remotest corners of the planet, every guest cabin is equipped with a workstation, so it is business as usual.
Speaking of business, some of the work aboard Leviathan is scientific and supports Inkfish’s mission. That explains the presence of a dive center, laboratory, hospital and workshop. Other unusual additions include a 3D printer that allows the crew to produce certain replacement parts while the vessel is operating remotely. Draak, on the other hand, was born as Equanimity and was essentially Newell’s floating office until Leviathan, the beast of a yacht, came along. The dragon features a large tender-handling area and a 12.6-tonne jib crane with an 11-metre reach. The former beach club and spa have been transformed into a dive center, medical treatment area and hyperbaric chamber. The main saloon now serves as a communal dining space for crew and guests, while the upper deck is home to a “chef’s lab.”
Few will get a look inside before the show, which makes the duo such an enigmatic presence in Poole, a harbor accustomed to welcoming incredible vessels such as Golden Odyssey and Deep Blue. It is only a matter of time before attention moves to the next spectacle involving Leviathan and Draak, Oceanco’s headline exhibits at Monaco, where the builder will present a new build and a major rebuild together for the first time. I guess there is strength in numbers after all!
