Designed inside and out with input from the owner, Leviathan moves away from conventional superyacht planning, placing day-to-day usability, crew workflow, and shared onboard experience at the center of the project.
Shared Spaces Replace Traditional Layouts
Interiors by Mark Berryman Design follow a clear brief - reduce operational friction while maintaining comfort and visual restraint. Materials such as honed stone, brushed metals, leather, and natural wool were selected for durability as much as appearance, limiting the need for ongoing maintenance.
A defining feature sits within the main staircase, where a glass installation carries the names of thousands of contributors involved in the build - a direct reference to the collaborative process behind the project.
Research, Gaming, and Purpose-Led Spaces
Several onboard areas replace features typically expected on a yacht of this scale. In place of a conventional beach club, Leviathan houses a fully equipped dive center, laboratory, hospital, and 3D printing workshop. These facilities support the yacht’s role within Newell’s research-focused organization Inkfish.
With a gross tonnage of 4,970GT, the bridge deck is given over to a dedicated gaming lounge with 15 stations and two racing simulators, while multiple informal lounges provide flexible social areas rather than fixed-use rooms.
Crew spaces receive equal attention. Finished in oak and wenge, they include a gym, whirlpool, basketball court, and shared relaxation areas. The intention is practical - improve working conditions and reduce fatigue, with the expectation that this feeds directly into service quality and safety onboard.
Clean Lines and Low-Maintenance Material
Exterior styling was developed in-house by Oceanco, working alongside Lateral Naval Architects and owner representatives Y.CO and YTMC. The profile is defined by clean, horizontal lines, with a light gray hull and superstructure accented by a turquoise bootstripe. At night, programmable lighting traces the deck edges, giving the yacht a distinct but controlled visual identity.
The layout departs from the traditional separation between guest and crew areas. Instead, shared spaces run throughout the yacht, including a large communal dining area designed to seat up to 54 people. This approach reflects Newell’s focus on treating the motor yacht as a functioning community rather than a strictly tiered environment.
With a greater purpose on how yachts are built, operated and owned, [Leviathan's] vision is rooted in the owner’s ethos of teamwork and community."

Material choices again link back to maintenance. Synthetic Bolidt decking replaces teak, while bead-blasted stainless steel railings and synthetic handrails reduce upkeep demands. An off-white exterior finish was selected to limit visible wear and cleaning frequency.
Across the aft decks, terraced levels lead down to a pool area with seating and an outdoor cinema, arranged to support group use rather than isolated zones.
Stability, Silence, and System Efficiency
Leviathan is built on Lateral DE-Series platform, developed for large vessels operating at moderate speeds with podded propulsion. Hull form and performance were refined through testing with MARIN, focusing on stability, efficiency, and onboard comfort.
The yacht achieves a natural roll period of over 12 seconds, supported by a stabilization system that pairs Quantum MagLift with XT fins. A seawater ballast system further adjusts trim and balance under different loading conditions.
Power comes from twin ABB DO980P Azipods, supported by a 5.5MWh battery system. This setup allows for silent operation during certain periods, along with peak shaving to improve overall fuel efficiency. Noise and vibration reduction were key targets throughout development, with attention paid to ventilation systems and structural acoustics.
Oceanco’s Next Projects Take Shape
According to YachtBuyer MarketWatch, the largest yacht database in the world, Oceanco currently has two major projects in build or on order, led by the 130-meter Oceanco Project Y727, scheduled for delivery in 2030 and set to become the largest yacht ever produced by the yard, with volume exceeding 11,000GT. Alongside this, the 80-meter Oceanco Project Y729 is now in outfitting at Alblasserdam, marking the first application of Oceanco’s Simply Custom platform, designed to streamline build timelines while retaining full customization.
Recent activity also highlights a broader shift toward fleet-based thinking. The 92.8-meter superyacht Draak has been fully rebuilt as a dedicated support vessel for Leviathan, reconfigured with dive facilities, expanded crew areas, and heavy-duty tender handling systems. Delivered projects such as the 111-meter Superyacht DreAMBoat further reinforce Oceanco’s position in the upper tier of large custom yachts, with current output defined by scale, technical depth, and highly specific owner-led briefs.

Leviathan closes out as a clear shift in how large yachts are conceived, with design, engineering, and layout shaped around real use rather than convention. Her position at 53rd in YachtBuyer’s YB100 by gross tonnage quietly reinforces that focus, with internal volume and usable space now defining what size really means at this level.
