Sunreef’s lineup just got even bigger and greener.

The Polish yard unveiled a new “sailing super catamaran” on Thursday, taking the total number of models on offer up to 23. The new Sunreef 35M Eco utilizes advanced green tech to ensure a silent, emissions-free cruising experience.

Founded in 2002, Sunreef has been at the forefront of sustainable yachting for over 20 years. The yard’s R&D team continues to push the boundaries, with pioneering innovations designed to help clean up the seas. (They’re even looking at ways to produce hydrogen onboard.)

Spanning 115 feet, the newest composite multihull is fitted with Sunreef’s custom-engineered batteries and state-of-the-art electric engines. Solar panels will also be embedded into the hull sides, superstructure, and bimini, allowing the cat to generate power from the sun. The yard has previously added this patented “solar skin” to several models, such as the newly unveiled Explorer Eco 40, the Eco 100, the Zero Cat, and the 80 Power Eco.

Sunreef didn’t share any details regarding speed or range for the new 35M Eco, but the aforementioned 80-foot cat is powered by 360 kW electric motors that can push it to 10 knots. The newcomer theoretically has an “infinite range,” given it can continuously get power from the sun so long as it’s shining. The clean, emissions-free energy would also power the hotel load at anchor.

The 35M Eco is not only sustainable but also spacious and stylish. With a beam of 48 feet, the yacht offers expansive living areas onboard. Positioned in the bow of the main deck, the owner’s stateroom provides stunning panoramic views and private access to an outdoor terrace. The luxurious guest accommodation, meanwhile, is located in the hulls and is fully customizable.

The 35M Eco offers an abundance of alfresco lounging areas, too. The vast walkaround aft deck, which Sunreef calls the “ocean lounge,” gives seafarers easy access to the sea and a hidden garage stocked with water toys. In addition, the sprawling flybridge features a plunge pool and bar.

Sunreef’s knack for creating elegant cats has attracted an A-list clientele, including former world No. 1 tennis star Rafael Nadal and two-time Formula 1 champion Fernando Alonso. Perhaps someone equally famous might snap up the new 35M Eco.
