The Sunreef 80 ECO is a 23.87-metre sailing catamaran that redefines luxury through innovation and sustainability. Designed and built entirely in-house at Sunreef’s Gdańsk shipyard, she blends avant-garde green technology with the brand’s signature comfort and bespoke craftsmanship. Her light, composite structure integrates a revolutionary solar skin — more than 200 m² of ultra-thin photovoltaic cells built into the hull, mast, and superstructure — capable of generating up to 34 kWp. Dual electric motors (up to 2 × 180 kW) provide silent propulsion, while hydrogeneration recovers energy under sail for virtually unlimited autonomy. With a beam of 11.53 m and exceptional stability, she offers vast, open spaces across the main deck, flybridge, and cabins, all bathed in natural light and customizable to the owner’s vision. Combining advanced energy systems, luxury design, and ocean-going capability, the Sunreef 80 ECO represents the new frontier of responsible yachting — powerful, elegant, and emission-free.
