Sinot Yacht Design & Architecture has unveiled its most ambitious vision to date with the Sinot AQUA yacht, a 112-metre hydrogen-electric superyacht that promises to redefine both sustainable travel and luxury living at sea. Created in collaboration with Lateral Naval Architects, the project combines groundbreaking clean technology with Sinot’s reputation for refined design. More than a futuristic concept, it is a statement on where the yachting industry is heading as it balances performance, elegance, and environmental responsibility.
Hydrogen propulsion at the heart of the design
The propulsion system of the Sinot AQUA yacht marks a significant departure from conventional engineering. Two vacuum-sealed tanks store liquid hydrogen at an extreme temperature of minus 423 degrees Fahrenheit, powering fuel cells that generate electricity with only water as a by-product. This allows for a completely emission-free operation while still delivering impressive capability. The yacht can achieve a top speed of 17 knots and a range of 3,750 nautical miles, enough for a transatlantic crossing between New York and Southampton.
By integrating the hydrogen tanks into the design itself, the Sinot AQUA yacht turns innovation into an architectural feature. Reinforced glass panels reveal the fuel system to guests, creating a rare opportunity to observe advanced clean energy technology in action. Rather than concealing the mechanics, Sinot places sustainability at the centre of the guest experience, blending ecological responsibility with visual theatre.
Fluid lines inspired by the ocean

Design philosophy plays a central role in the Sinot AQUA yacht. The exterior features flowing wave-like contours, layered platforms cascading aft, and an expansive swim deck that dissolves the usual separation between vessel and sea. This focus on fluidity continues indoors, with five decks that flow seamlessly from one space to another, maintaining open sightlines across the water.
Floor-to-ceiling windows ensure the ocean remains present at every moment, whether guests are gathered in lounges, dining areas, or private suites. Natural light is maximised throughout, reinforcing the idea that life on board should always remain connected to the surrounding marine environment.
Wellness as a defining feature

The Sinot AQUA yacht dedicates an entire deck to wellness, establishing a new benchmark for superyacht living. Facilities include a hydrotherapy suite, a fully equipped spa, and a gym positioned at water level, offering panoramic ocean views during workouts. This commitment to wellbeing transforms exercise and relaxation into immersive encounters with the sea.
Perhaps the most striking feature is a circular tunnel linking the main salon to the spa. This architectural element not only connects spaces but symbolises the transition from communal to private, creating a deliberate shift in atmosphere that prepares guests for restoration. It highlights Sinot’s ability to pair function with experience, ensuring design serves both body and mind.
A pavilion for ultimate privacy
Accommodation for the owner is housed within a multi-level pavilion, designed to feel as expansive as it is secluded. The space features soaring 3.8-metre ceilings, wooden partitions that create intimacy without disrupting flow, and areas adaptable for both private retreats and social gatherings. Positioned with commanding views across the vessel, the pavilion represents the Sinot AQUA yacht’s most exclusive living environment, combining privacy with grandeur.
A sculptural spiral staircase rises at the yacht’s centre, encircling a cylindrical atrium and ending at an art installation. This architectural centrepiece doubles as a viewing gallery, where guests can see the hydrogen storage system through reinforced glass. It is both a design flourish and a reminder of the technological innovation that powers the vessel.
Market impact and industry relevance
When first revealed, speculation quickly arose around the Sinot AQUA yacht, with reports of a $645 million price tag and rumours linking it to Microsoft founder Bill Gates. Sinot clarified that the yacht remains a concept rather than a commissioned project, positioning it as a showcase of what is possible rather than a near-term launch.
What matters more than speculation is the message AQUA sends to the industry. It demonstrates that high performance and zero emissions can coexist without compromise. The 3,750-nautical-mile range proves that long-distance voyages are possible using hydrogen propulsion, while the luxury design ensures comfort and sophistication remain uncompromised.
A blueprint for yachting’s future
The Sinot AQUA yacht sets a striking precedent for what tomorrow’s superyachts could achieve. By combining zero-emission propulsion with fluid architecture and refined living spaces, it shows that sustainability can sit at the heart of luxury without compromise.
From its hydrogen fuel cells to its transparent design features, every detail of AQUA invites guests to experience the sea in a new way—closer, cleaner, and more connected. It signals a future where the most desirable yachts will not only offer grandeur and privacy, but also a lasting respect for the oceans they traverse.
