Watch the New 111m Oceanco Superyacht Leviathan Launch: The 50 Shades of Grey Yacht

The 111m superyacht Leviathan from Oceanco has emerged in launch footage that exhibits a striking departure from the yard's usual aesthetic.

The video captures her moving clear of the shed and into daylight, offering the first uninterrupted views of her exterior details and unconventional material choices.

A Uniform Grey Finish from Bow to Stern

The footage shows Leviathan’s sharp profile finished entirely in shades of grey, from her hull and superstructure to her decks and even the pools. This uniform palette departs from the high-contrast schemes seen on most yachts of her size.

Given the owner is widely believed to be Valve co-founder Gabe Newell, the decision to avoid traditional teak and instead opt for grey synthetic or composite decking may be tied to his interest in practical, low-maintenance solutions. It may also reflect the direct input of crew members, who were involved in the yacht’s design and likely influenced choices that reduce upkeep and streamline operations.

Distinctive Deck Patterns and Lighting

Close-up shots reveal a circuit-board-style motif embedded across multiple deck levels. The geometric design appears in guest and crew areas alike, suggesting a deliberate theme carried throughout. Subtle references to Newell’s gaming background are possible, though unconfirmed.

In a separate video, Leviathan appears to have integrated blue LED strips that illuminate these patterns after dark, with the light following the lines of the motif to give the decks definition and depth. The effect is particularly pronounced at the stern beach club, which continues the grey scheme without interruption.

A sanctuary of comfort where silence meets strength, Leviathan wrapped in her sharp lines represents a superb synergy of form and function.”

Forward footage captures a touch-and-go helipad marked with a large “H.” While its scale hints at use for lighter helicopters rather than permanent storage, its placement on the foredeck ensures easy access without disrupting aft guest areas.

Hints at Interior Style

Although the interiors of the motor yacht are not shown in the footage, the use of full-height glass bulkheads suggests the same minimal-maintenance, light-filled approach seen on the exterior. It aligns with the idea, already associated with the owner, of directing crew resources toward service and specialist operations rather than upkeep.

The integration of the restrained color palette, patterned decks, and integrated lighting marks her out visually from both her Oceanco stablemates and other yachts of similar scale. For viewers, it’s the first complete glimpse of a project that appears to fuse functional practicality with personal aesthetic cues from her high-profile owner.

With a gross tonnage of approximately 5,000 GT, she is Oceanco’s largest build to date and is projected to enter the YachtBuyer YB100 ranking of the world’s biggest yachts within the top 50 by volume.

Sea trials are scheduled to begin in the coming weeks, with more details on her scientific capabilities and operational profile expected later this year. For now, the launch video offers the first full look at a yacht that challenges convention, both in appearance and in philosophy.
