Eco Sail


Sunreef Yachts unveiled the Eco range of eco-friendly catamarans in 2019, offering cutting edge electric propulsion, naturally-sourced sustainable materials, smart energy management and new technologies including integrated solar panels in the hulls and superstructure. This range looks towards a greener future of responsible, environmentally conscious yachting.

The Sunreef Eco range is comprised of luxury catamarans that are low maintenance and provide ultra-silent, fume and wake-free cruising, with minimum impact on the environment while still offering the best of autonomy, comfort and performance one would expect from a Sunreef catamaran. Electric yachts are also saving owners money by significantly reducing costs for diesel and maintenance expenses. 

Fossil-fuel free boats rely on energy from the natural elements, such as sun and wind, which is why this range uses a combination of solar panels and wind generators alongside the electric batteries that store the harvested energy.

With the industry’s lightest panels, smart engineering and ultra-efficient lithium battery packs, Sunreef Yachts Eco catamarans find the perfect balance of energy production and consumption.

The Eco range is available in 50ft, 60ft, 70ft, 80ft and 100ft- enquire for more details on specific models and sizes. The Eco is also available as a power catamaran. 

What We Say

We fell in love with the idea of a state of the art, luxury catamaran, offering full freedom of customisation, constructed out of sustainable materials and equipped with innovative, green technologies to maximise its energy efficiency.

We are a massive fan of the use of naturally-sourced and eco-responsible materials such a basalt and linen-based structures in the production of hulls, superstructures and furniture, without any compromise on luxury and comfort. The range also offers fully recyclable sails that offer great performance but can also be given a second life when they need to be replaced.

An ecological yacht, equipped with electric motors powered by light batteries, ensuring quiet sailing, is definitely something we say YES to!

The incredible ‘Marie-Joseph’ is the latest catamaran from the Eco range to hit the water. Images of her cruising around Dubai can be found in the gallery below. This is a seriously impressive yacht with all the advanced tech features we would expect from the range, most visibly, the ultra-light integrated solar skin on the hull, superstructure and mast, as well as the classic, elegant lines and bold design.

The interior design follows the ‘green’, environmentally conscious theme, with a clean, sophisticated palette, the use of natural and sustainable materials as well as large panoramic windows in the saloon to draw in natural light helping guests feel closer to the surrounding environment even from inside the saloon.

What The Builders Say

This green philosophy of yachting is present in each and every aspect of the Sunreef Yachts Eco catamarans. Their design incorporates wind generators, ultralight custom-engineered lithium batteries, nontoxic bottom paints, green composite structures as well as state-of-the-art watermakers.

The Sunreef Yachts Eco harvest power from the sun more efficiently than most solar catamarans. In-house designed and manufactured by the shipyard, Sunreef Yachts’ solar panels are fully-integrated with the composite bodywork, vastly increasing the amount of solar power generated.

Solar Panels:

A significant feature is the integrated solar skin made up of light weight and flexible solar panels on the hull and superstructure, located perfectly to ensure the new elements do not impose on the elegant design of the classic Sunreef yachts. Made of photovoltaic cells, solar panels convert sunlight into electrical power, so the more panels fitted on the yacht, means more power can be generated. Customisation is still a possibility with the Eco range, and solar panels are designed and made by the shipyard so can be combined with any yacht’s surface and fit any customisation requests as they are easy to adapt. 

Hydro-Generation Technology: 

Sunreef’s Eco-friendly yachts use hydro generation technology, designed to generate power whilst sailing. With this, power can be generated from the propeller rotation while the yacht is underway. This energy can be used to power the propulsion battery bank or the electronics onboard. It is a reliable and sustainable source of power. 

Electric Engines:

Enter a world of vibration and fume-free navigation. Sunreef’s eco-friendly catamarans feature advanced electric engines offering the best of autonomy and performance for a responsible yachting experience.

Thanks to innovative propulsion solutions, the shipyard’s eco-friendly catamarans combine fuel savings, low-maintenance and ultra-silent operation. Electric propulsion is not only the green choice for conscious yachting but also brings more freedom, peace of mind and luxury on board.

Hybrid Engines:

Sunreef Yachts eco-friendly catamarans have the option to be equipped with ultramodern hybrid propulsion systems as well. Besides significantly reduced Co2 emissions, hybrid engines take eco cruising to the next level by combining the best of electric motoring with the advantages of thermal engines.

Hybrid engines not only offer reliable propulsion but can also be used to recharge the yacht’s battery bank for even more energy-efficiency. Eco-friendly yachts by Sunreef Yachts are a guarantee of solid performance, low-maintenance and Atlantic-range.


Relying on wind as an essential source of propulsion is the most natural way to think about yachting. Sunreef Yachts’ sailing range of eco-friendly catamarans offers top quality rigging and fully-recyclable performance sails. Wind can also be a precious support when it comes to motor yacht propulsion.

The shipyard’s range of Power eco-friendly yachts can be fitted with high-performance kites to combine the advantages of eco motoring with wind propulsion. Frequently used for towing large container ships, kites are an extremely powerful support for leisure crafts.Sunreef Yachts’ motor yachts equipped with kites enjoy oceanic range, massive fuel savings, more visibility and safety.

Wind Turbines: 

The Eco range also comes with the possibility of added wind turbines. The turbines are designed to produce power from the wind to keep the yacht’s battery bank charged. They are great for generating power throughout the day, but also in the night and in cloudy weather, when the yacht cannot rely on solar energy, and can operate in a range of wind conditions from very light breeze to storms. 

Sustainable Materials:

The Eco-range is dedicated to using sustainably and ethically sourced materials for both the exterior and interior design which is becoming an important issue for the shipbuilding industry. Sunreef Eco yachts are using ethically-sourced teak or cork-based materials for the decking as a green alternative to traditional teak decking. 

In order to reduce energy consumption on board, this range features carefully-calculated insulated interiors thanks to sustainable insulation materials. This means the yacht’s interiors maintain stable temperatures and retain both heat. The air-conditioning system is powered by batteries allowing for silent operation.
