A new class of sailing superyacht

The 35M marks Sunreef's step up into the sailing superyacht world, a 115-foot catamaran built as an Eco yacht from the first sketch. It brings the yard's proven solar and battery technology to a scale that changes what emission-free sailing can mean. Above the production sailing range, it is a bespoke ship in every sense. It is aimed at owners who want to lead on sustainability at the top of the market. For a buyer who values both craft and conscience, it answers a brief few yards can meet.

Every 35M is fully custom, and the Eco specification is central to the concept. Solar panels, electric propulsion and advanced energy systems let the yacht operate silently without fossil fuel for long stretches. The result is a genuine superyacht that can hold an anchorage in silence for days. This is green engineering carried through without compromise on luxury. The ability to sit at anchor for days with no generator running is the promise that sets the 35M apart.

Design and deck life

With a beam of 14.7 metres the 35M has the deck space of a much larger monohull superyacht. The layout spreads social areas across several levels for sun, shade and dining. The aft platform opens the yacht to the sea for swimming and toys. Owners shape the exterior to host in the manner they prefer. The width gives the yacht a stable, planted feel that makes long lunches and calm nights at anchor a pleasure.

The design carries Sunreef's low, wide signature into superyacht proportions with real elegance. Custom paint, decking and detailing set each yacht's character. The rig is drawn for efficient sailing that keeps the batteries charged under way. The whole exterior is built for a life lived largely outdoors in the sun. Owners who want a landmark yacht find the clean, modern lines carry real presence in any harbour.

Interior and accommodation

The interior headline is a full-beam forward owner's suite on the main deck with 270-degree views, a super-kingsize bed, a walk-in dressing room and its own bathroom. Guests are accommodated in further cabins including a VIP suite with its own lounge. Crew quarters house up to six for full professional service. Sunreef finishes every surface to a bespoke brief in the owner's chosen materials. That forward master is one of the most striking owner's cabins afloat, wrapped in glass and light.

Natural light fills the saloon and cabins through generous glazing. Storage, tankage and systems are engineered for long, self-sufficient voyages. Climate control is designed to sit within the Eco energy budget. The interior feels like a bespoke residence carried under sail. Owners who spend real weeks aboard find the volume makes extended stays feel like life at home.

The Eco engineering

The 35M was engineered around its energy system, with composite-integrated solar panels feeding custom high-capacity batteries and electric propulsion. Under sail the rig drives the yacht while the sun keeps the banks charged. At anchor the yacht runs silent, with no generator and no local emissions for extended periods. The integration of solar into the structure is what makes the surface area possible without spoiling the lines. That structural approach lets the yacht carry a large solar array while keeping its elegant profile.

Sunreef builds the composite platform in house for the stiffness a superyacht rig demands. The energy management is tuned for genuine long-range autonomy. The whole system is designed so an owner can sail the world without depending on fuel. The engineering brief was emission-free cruising at superyacht scale. The technology draws on years of Sunreef solar experience, so a buyer is choosing proven engineering at a new size.

The owner it suits

The 35M suits an owner who wants a bespoke sailing superyacht that leads on sustainability without giving up comfort. It rewards those who intend to cruise the world in silence and self-sufficiency. Buyers who value a landmark owner's suite and full crewed service will find both here. It is a statement yacht for a values-driven owner. It fits the owner who wants their flagship to reflect how they think about the world, not only how they travel it.

It also carries genuine prestige as one of the first true emission-capable sailing superyachts. The blend of green engineering and bespoke luxury travels well at the top of the market. For an owner ready for a crewed ship that still sails cleanly, the 35M is a landmark. Life aboard is grand, quiet and free of the fuel dock. Owners who care about their footprint find a yacht that lets them roam without leaving one at anchor.

Who it is for: Owners who want a bespoke sailing superyacht that leads on sustainability while offering a landmark full-beam owner's suite.
