The Sunreef 100 Eco sailing catamarans come with solar panels built into the hull.
Sunreef Yachts has recently been tasked with constructing two Sunreef 100 Eco superyachts, both sailing catamarans sold to returning clients. One of these vessels is expected to be delivered to Europe by the end of 2025, while the other will make its way to the Americas in 2026.
This Polish shipyard is leading the charge for sustainability in the superyacht industry as interest in large, eco-friendly catamarans grows worldwide.
The Sunreef 100 Eco is crafted to ensure an emissions-free cruising journey characterized by complete silence and luxury. Utilizing advanced green technologies developed internally by Sunreef, both catamarans will have composite-integrated solar panels to maximize solar power production.
Equipped with custom-designed batteries and cutting-edge electric motors, the Sunreef 100 Eco provides hours of electric propulsion without emissions or vibrations, delivering a smooth sailing experience as the yacht’s hydro-generators ensure consistent green energy. These features contribute to a cruising range of 2,000 nautical miles for the 100 Eco.
Expandable Ocean Lounge
A standout feature of the catamaran is its hidden aft garage, which can accommodate a jet ski and a variety of water toys. Another highlight is the expansive Ocean Lounge, merging the aft platform and retractable balconies. Designed for sunbathing, relaxation, and watersports, this lounge grants direct access to ample toy storage and diving equipment.
With its state-of-the-art green technology and impressive living space, the Sunreef 100 Eco exemplifies sustainable superyacht design. This custom all-electric luxury vessel joins Sunreef’s Eco lineup of sailing catamarans alongside the 50 Eco, 60 Eco, 70 Eco, and 80 Eco.

Equipped with twin 270kW electric engines, the Sunreef 100 Eco ensures a sustainable yachting journey, leveraging ultralight, high-performance batteries alongside Sunreef’s proprietary solar power system. Thanks to the shipyard’s award-winning technology, the vessel can incorporate up to 242.5 square meters of composite-integrated solar panels, generating up to 46kWp.
The Eco Ethos
Adhering to Sunreef Yachts’ Eco philosophy, the 100 Eco utilizes a range of responsibly sourced or recycled finishing materials and features an ultramodern, energy-efficient air conditioning system.
Sunreef’s Eco catamarans stem from a comprehensive approach to eco-friendly cruising. They provide advanced green propulsion technologies, sustainably sourced finishing materials, intelligent energy management systems, and innovative technology including the proprietary composite-integrated solar power system developed in-house for the builder’s latest solar catamaran range.
The design also encompasses wind generators, eco-friendly bottom paints, green composite materials, cutting-edge watermakers, and water conservation systems.
Sunreef’s electric catamarans may come with modern hybrid propulsion systems. In addition to significantly lowering CO2 emissions, hybrid engines elevate eco-friendly cruising by merging the advantages of electric propulsion and thermal engines (heat-generating).
The Sunreef 100 Eco is built for hours of electric propulsion.
Hybrid engines not only provide dependable propulsion but also recharge the yacht’s battery bank, enhancing energy efficiency. Utilizing wind as a primary propulsion source is the most natural concept for yachting. Sunreef’s electric sailing catamaran range features high-quality rigging and fully recyclable performance sails.
Wind can serve as a valuable aid in motor yacht propulsion. The shipyard’s lineup of eco-friendly power yachts can incorporate high-performance kites, which are often used to tow massive container ships, to further capture wind energy for leisure vessels.
Hull Optimization
When powered by electric motors, all Sunreef yachts maintain energy efficiency thanks to advanced hull designs created using realistic computer simulation scenarios at the shipyard. Modifications to hydrodynamic and aerodynamic aspects are integral to the development of each model’s hull.
Engineers are continually enhancing hulls for optimal energy efficiency, seaworthiness, and performance across different marine conditions.
The aft garage remains concealed.
Weight Efficiency
Weight optimization is vital for energy-efficient yachts; Sunreef’s Eco catamarans can be constructed using lightweight carbon fiber to decrease the overall weight and improve energy efficiency. Carbon is utilized for masts, booms, and structural reinforcements.
Lightweight lithium battery banks are strategically placed onboard to reduce their impact on the yacht’s movement while at sea, and solar panels installed are among the lightest solar power systems globally.
Energy And Water Management
To cut down on energy use aboard, Sunreef’s yacht collection incorporates well-insulated interiors made from sustainable insulation materials, helping maintain stable temperatures within living spaces that retain heat and cold seamlessly. The silent smart air-conditioning system runs on battery power.
Smart energy management is crucial on an energy-efficient yacht. To sustain all house loads and air conditioning while maximizing the generator’s minimal use throughout the day, a yacht must achieve a balance between energy production and consumption.
Sunreef Eco catamarans excel in this regard due to intelligent engineering and highly efficient lithium battery packs that can be conveniently charged globally across varying voltage ranges. A special eco mode is under development by Sunreef’s R&D department to further reduce energy consumption.
The catamaran was designed for emissions-free cruising in complete silence.
Generating fresh water is critical for sustainable cruising. Thanks to highly efficient watermakers and advanced purification systems, Eco yachts can access an infinite supply of fresh water, allowing the avoidance of plastic bottles onboard.
The yacht’s boiler can be heated using energy from solar panels or an inverter-powered heater, and a rain-collection system helps conserve water for deck washing.
Linen and Basalt
Sunreef’s Eco catamarans often utilize basalt and linen in the manufacturing of hulls, superstructures, and furnishings. Basalt, a dense, hard volcanic rock, serves as a sustainable base material.
Basalt fiber excels over glass fiber in strength, and it is also more environmentally friendly to produce, as its manufacturing process does not emit greenhouse gases. It exhibits no toxic reactions with air or water, is non-combustible, and explosion-resistant.
Linen is another natural material employed in the Eco range’s construction. Sourced from flax, it is the strongest and stiffest natural fiber, non-toxic, safe to produce, and carries a minimal carbon footprint.
Sunreef uses high-quality responsible materials including fabrics, cork, and reclaimed teak.
Other Sustainable Materials
Sunreef is committed to ecologically responsible yacht designs that utilize premium materials without sacrificing luxury. Eco catamarans limit the use of animal hides, offering a range of natural fabrics and alternatives to genuine leather instead. Interior spaces can feature advanced hardwood flooring systems or reclaimed teak sourced from previously used structures.
Countertops made from compressed paper-based materials provide solid, practical, and lightweight surfaces. This innovative approach not only results in a luxurious finish but also allows for easy repairs, as scratches can be quickly removed through heat application.
Decking can use cork, a green and fully recyclable alternative to traditional teak. Reusable and recyclable synthetic teak that is non-PVC-based is also available for decking.
Non-toxic, silicon-based hull bottom paints provide effective protection against marine growth while maintaining low surface roughness. These slick, durable coatings significantly minimize drag, leading to enhanced performance and improved energy management.
Sunreef’s electric sailing catamarans offer high-quality rigging and fully sustainable performance.
The Eco sustainable yachts from Sunreef feature completely recyclable sails that combine great performance with environmental responsibility. Recycled sailcloth is repurposed into durable bags and accessories.
“The Sunreef 100 Eco is a remarkable electric superyacht,” said Francis Lapp, the founder and President of Sunreef, to Yacht Style. “It brings together expansive living areas with effortless sailing and cutting-edge green technology.
“This would be an excellent choice for the Asia-Pacific, especially in Australia and New Zealand, where we are receiving increasing attention. We have a strong local dealership there, and feel customers are genuinely interested in our new catamarans.”
