Leveraging clean & renewable energy
A sustainable energy source
Our mission is centered on building environmentally friendly boats.
Sailing in harmony with nature while minimizing our ecological footprint requires innovative technical developments and a stronger commitment to ecology through more sustainable energy management. Our boats are designed to be self-sufficient and produce their own electricity.
But what is the real story?
Can green energy alone cover the needs of a boat offering all modern conveniences—on-board electronics, heating, air conditioning, household appliances, etc.? It all boils down to how you use a Windelo catamaran and its equipment.
Energy autonomy varies according to the lifestyle and habits of each individual user. However, aboard Windelo catamarans, comfortable eco-friendly sailing is a reality.
Our cutting-edge catamarans blend high performance with eco-friendly design, incorporating a powerful, robust, and efficient electric propulsion system.

"Energy production is at the heart of our concept. Windelo catamarans harness wind power and solar energy to meet all your requirements aboard. With a continuous supply of renewable electricity, they provide genuine energy autonomy, paving the way for truly eco-friendly sailing." - Gautier Kauffmann
Hydro-generation
While sailing at speeds over 8 knots, Windelo’s electric engines act as hydro-generators producing energy continuously.
The boat’s speed generates a water flow that rotates the propellers, similar to wind turbines. So, every mile sailed helps recharge the battery bank.
At an average speed of 10 knots, Windelo’s hydro-generation capacity efficiently covers essential energy needs and recharges the batteries, without the need for additional energy sources.
Activating hydro-generation has a minimal impact on sailing performance. Above 10 knots, the drag is negligible.
As standard, our catamarans are equipped with brushless electric engines, custom propellers, and a lithium battery bank, to generate hydroelectricity.
There’s no need for a diesel engine or generator to recharge the batteries. Hydro-generation is a discreet, efficient, and sustainable alternative for confident, eco-friendly sailing.

Solar panels
The superstructures of the New Windelo have been designed to integrate the highest possible number of solar cells. For optimal performance, we have chosen one of the best solar technologies on the market.
The roof and deck of the New Windelo can accommodate up to 6,000 W of solar panels, guaranteeing continuous energy production for extended autonomy at sea.
Durable, custom-made, flexible panels enable seamless integration, ensuring optimal performance and unobstructed movement in circulation areas.
Technology
The flexible “Flush Mount” panels on Windelo catamarans feature advanced solar technologies.
Boasting monocrystalline silicon cells, these panels achieve a light-to-electricity conversion rate of 24%, significantly higher than the 8-22% typical efficiency of conventional panels.
Concealed electrical contacts at the back of the cells allow for a discreet, flush-mounted installation that seamlessly integrates with the Windelo’s elegant design.

Durable and featuring a non-slip walkable coating, the solar panels blend seamlessly into the deck’s circulation areas, ensuring total freedom of movement.
Capacity & Installation
Solar production is one of the main energy sources on a Windelo catamaran. Our packs consist of flexible solar panels, combining design, safety, and production performance.
With optimal sunlight, a good installation can meet all onboard electrical needs and recharge the batteries. At anchor, a 6kW solar pack is enough to power a 220V air conditioner autonomously, without needing a generator!
The solar panel layout has been meticulously designed to optimize energy production. Each area consists of panel subgroups and a network of regulators, ensuring continuous solar production even when parts of the deck are shaded.
In total, the solar packs can generate up to 6,000W of power.

Control Interface
The Windelo Boat Management System (BMS) includes a dedicated control page for the solar array.
Accessible via the multifunction screen and mobile app, this user-friendly interface monitors energy production in each of the four solar zones.
It also features an energy flow visualization page, allowing users to adjust onboard electrical consumption as needed.
With accurate real-time data on the balance between energy production and use, users can optimize Windelo’s electric autonomy without relying on the generator.

Wind Turbines
Sailing in harmony with nature is at the core of our philosophy. By equipping our catamarans with wind turbines, we offer a sustainable, silent solution that complements solar energy perfectly.
At sea, wind turbines generate electricity continuously, even on cloudy days, allowing sailors to enjoy unlimited autonomy.
Windelo catamarans can be equipped with 500W wind turbines, providing a near-permanent energy source. With steady 12-knot winds, two turbines can produce up to 2.8kWh of energy daily, offering reliable supplementary power in all conditions.
We have selected compact, lightweight wind turbines with “Low Noise” carbon blades designed for minimal vibration and noise.
One or two wind turbines can be installed on the Windelo’s aft platforms.
Production range: 3.5 to 35 knots.
