A vessel of monumental grace and engineering precision, Leviathan stands as a testament to the evolution of modern superyacht design. In the rarefied world of bespoke yacht craftsmanship, few launches command the reverence reserved for an Oceanco. This autumn, the Dutch shipyard has once again redefined the boundaries of maritime luxury with the delivery of its latest creation the 127-metre Leviathan. Known internally as Project Y722 during her construction, the vessel has emerged from the Oceanco yard in Alblasserdam as a vision of modern artistry, precision and serene power. The name Leviathan carries both biblical weight and poetic resonance, perfectly befitting a yacht of this scale and presence. With a design philosophy that balances engineering might with sculptural beauty, Leviathan represents the culmination of years of collaboration between the world’s most accomplished naval architects, designers and artisans.
A Vision in Motion
From her sweeping profile to her commanding silhouette, Leviathan embodies fluidity in form and function. The exterior was penned by Espen Øino International, whose portfolio of iconic yachts continues to define modern seascape architecture. Øino’s design for Leviathan is simultaneously bold and graceful, with clean lines that taper elegantly toward the stern. The sheer scale of the vessel is tempered by visual harmony a floating sculpture that seems to glide rather than impose.
Her proportions are perfectly balanced: 127 metres in length, with a beam wide enough to create vast interior volumes without compromising the yacht’s sleek aesthetic. Every curve has purpose, every surface intention. The hull, sculpted for both stability and efficiency, reflects the meticulous craftsmanship and technical mastery that have long distinguished Oceanco’s reputation.
The Interior World
Inside, the design narrative continues with interiors conceived by Paris-based studio François Zuretti. The collaboration between Øino and Zuretti has resulted in a seamless dialogue between exterior and interior spaces where architecture and artistry coexist in effortless conversation.
Zuretti’s vision for Leviathan celebrates light, texture and spatial freedom. The interiors are described as “contemporary classic,” marrying sculpted forms with warm natural materials. Large windows blur the line between ocean and interior, allowing the sea to become an ever-changing artwork within. The design incorporates neutral tones layered with tactile finishes: oak, limestone, bronze and fine silk. The result is a living environment that feels at once monumental and intimate, a private residence that moves across the sea.
Among the many highlights is a double-height main salon that opens onto a sweeping aft deck, creating a sense of openness rare even among yachts of this magnitude. The grand staircase, finished in sculpted marble and brushed metal, spirals upward through multiple decks like a work of art. Across each level, terraces unfold toward the water, inviting quiet reflection as much as celebration.
Designed for Experience
Leviathan is more than a yacht; she is an experience crafted for those who view the sea as a place of meditation and discovery. Her amenities are conceived not as excess, but as extensions of comfort and creativity.
A vast wellness centre occupies one of the lower decks, featuring a spa, hammam and ocean-view gymnasium. An infinity pool merges seamlessly with the horizon, while private lounges and cinemas invite leisure in every form. The upper decks are reserved for private quarters, offering panoramic views and complete discretion.
A helipad ensures swift arrival, while tender bays and a beach club provide direct access to the water. Every feature has been designed to enhance the rhythm of life on board fluid, unhurried and deeply connected to the surrounding seascape.
An Evolution in Craftsmanship
Oceanco’s approach to construction has long set the benchmark for innovation and artistry. Each vessel is the result of bespoke engineering, built not in repetition but as a singular expression of its owner’s vision. With Leviathan, that philosophy reaches its most advanced form yet.
Built at Oceanco’s purpose-designed facilities in the Netherlands, Leviathan showcases the shipyard’s commitment to precision and sustainability. The construction process utilised cutting-edge digital modelling and hybrid propulsion systems that prioritise efficiency and reduced emissions. While Oceanco remains discreet about specific performance details, Leviathan is believed to integrate advanced energy management systems and waste reduction technologies that place her at the forefront of sustainable yacht design.
The vessel’s steel hull and aluminium superstructure were crafted to the most exacting standards, with every weld, joint and finish overseen by specialists in metallurgy and marine architecture. From propulsion to interior detailing, Leviathan exemplifies the union of technology and artistry that defines Oceanco’s ethos.
A Cultural Statement
The delivery of Leviathan is not simply a milestone for her builders but a cultural statement within the evolving narrative of luxury travel. She represents a shift from conspicuous display to considered design from opulence to equilibrium.
Where older generations of superyachts sought to impress through scale alone, Leviathan achieves presence through proportion, craftsmanship and restraint. She embodies a new chapter in yachting culture, one in which luxury is measured not by volume, but by harmony.
Within her walls, every element has been chosen not to astonish, but to endure. Lighting is designed to evoke warmth rather than glare; materials invite touch rather than distance. Even the soundscape has been tuned for tranquillity, allowing guests to hear the rhythm of the waves as they move through each space.
A Collaboration of Visionaries
Behind the creation of Leviathan lies a consortium of world-leading experts whose combined expertise defines the pinnacle of contemporary yacht design. Oceanco’s in-house team worked alongside Espen Øino International and François Zuretti Design, supported by naval engineering partners Lateral Naval Architects.
The collaboration reflects a philosophy that has come to define the superyacht industry’s most forward-thinking projects: that great design is achieved through dialogue. From initial concept sketches to final launch, the team sought to balance artistry and performance, emotion and innovation.
Each craftsman, designer and engineer involved in Leviathan contributed to a singular ambition, to create a vessel that transcends luxury and becomes legend.
The Launch
When Leviathan emerged from Oceanco’s drydock for the first time, her presence was awe-inspiring. Her hull gleamed in a subtle metallic hue, catching the morning light as she was lowered into the water. The event marked the culmination of years of design and construction, yet the yacht’s story is only beginning.
Following sea trials and final outfitting, Leviathan has now joined the global fleet as one of the largest and most sophisticated private yachts ever built in the Netherlands. Her maiden voyage will remain confidential, in keeping with the discretion that surrounds vessels of this stature, but her silhouette has already joined the pantheon of modern maritime icons.
Legacy on the Water
For Oceanco, Leviathan represents both a triumph of engineering and an affirmation of philosophy. Each of the shipyard’s projects is conceived not merely as a vessel, but as an heirloom, a creation meant to inspire as much as transport.
In Leviathan, that vision is realised to perfection. She glides through open water not as a showpiece of excess, but as a living embodiment of artistry, power and grace. Her name evokes mythology, but her presence is distinctly modern, a creation that bridges the ancient allure of the sea with the technological future of exploration.
As she sails from the Dutch coast toward destinations unknown, Leviathan carries with her the signature of Oceanco’s craftsmanship and the enduring truth of beauty: that true luxury lies not in what is seen, but in what is felt.
