“The Sunreef 80 Eco embodies a new boating philosophy. This yacht proves that boating and sustainability go together and that, if you manage your energy consumptions properly and use the right green technology, you can cruise emissions-free.” She completely won over Francis Lapp, Founder and President of SunreefYachts. The Polish shipyard stands for a new wave of sustainability and creativity in the yachting catamaran world.
Marie-Joseph is a fully autonomous craft, unique in the yachting industry, utilizing revolutionary green technology for fuel-free cruising in total silence and luxury. Part of this technology is used as a design element too. One of the most striking features of the exterior design is the full integration of solar panels into the composite bodywork.
Adopting Sunreef’s in-house technology, solar cells cover the hulls, the mast, the Bimini roof, and the superstructure. “We searched for a solution that would not only make photovoltaic technology super-efficient but also visually appealing,” explains Nicolas Lapp, CTO & Co-Founder of Sunreef Yachts. “We want to prove that a sustainable yacht does not have to compromise on refined aesthetics.” Sunreef entirely engineered and produced this patented system in-house, offering optimal efficiency: covering a total area of 164m², the on-board solar panels can generate up to 45.5kWp.
For generating energy under sail, the on-board sail wardrobe includes a main sail, Genoa, gennaker, and staysail with performances of about five knots in light airs and more than double that in anything over 15 knots of breeze. While under sail, the Sunreef 80 Eco takes energy from the passive motion of the two propellers through an advanced hydro-generation system. The system can generate more than 15kW while sailing above seven knots.
The catamaran’s smart energy management system along with custom-engineered batteries makes for optimal energy efficiency. This lets all energy obtained via the solar power and hydro-generation system be stored and reused to power both the electric propulsion and house appliances. As a catamaran, Marie-Joseph impresses for its spaces that provide comfort with elegant, luxurious design choices for the interior.
The exterior features ample areas for relaxing and entertaining: the flybridge features impressive lounging areas, large sun pads, and a wet bar; the foredeck is unique with traditional trampolines separating the two hulls and a sunken deck with large sun pads and a Japanese-style tatami table; and in the aft cockpit, guests enjoy a full-beam relaxation space with a large daybed, dining table, and swim platform.
It is fully connected to the vast main deck saloon through a large sliding door that opens fully; amidships, there is a height-adjustable and modular table and two identical oversized lounging sofas to port and starboard. It is a marvelous space to lounge and light-flooded through wrap-around, panoramic windows. “The interiors onboard Marie-Joseph have been designed to be open, universal, and relaxing. This has been achieved through a good consideration and understanding of the layout, but also through the color palette which is characterized by dark colors,” continues Nicolas Lapp.
The palette chosen, a selection of gray, beige, and black tones, creates a cozy environment for guests on board. Natural finishing materials and wide-open spaces filled with light and symmetry are the key features of the interior design. With luxurious accommodation for eight guests, the catamaran’s starboard hull houses an opulent and light-filled master suite.
The generous en-suite bathroom follows the contemporary style of the master stateroom. The custom layout also includes a large VIP cabin in the middle section of the portside hull as well as two identical guest cabins in the bow portion of each hull. Marie-Joseph has all the qualities to become a private retreat, while also often being the perfect platform for socializing. For Sunreef Yachts, a new horizon is opening on the road to carbon-free.
The shipyard recently announced an order for a hydrogen yacht, which promises to be an exciting new project. “We feel the company must keep investing effort and talent into many different technologies to push innovation forward,” Sunreef Yachts’ president says, “and the hydrogen Sunreef 80 will be a wonderful opportunity to do so.”
