EnergyMatic: The Award-Winning Propeller Redefining Hydrogeneration and Sailing Efficiency
In the rapidly evolving world of sustainable yachting, energy autonomy is the ultimate goal. Whether navigating a fully electric vessel or a modern diesel cruiser equipped with power-hungry electronics, the need for a reliable, “green” energy source is paramount. Enter EnergyMatic, the revolutionary propeller by EWOL that transforms the way sailors think about propulsion and power generation.
Initially unveiled at the 2022 Newport Boat Show, EnergyMatic immediately made waves by winning the prestigious “Best Green Product” award. This recognition underscores its role as a game-changer for eco-friendly sailing, offering a seamless bridge between high-performance propulsion and efficient energy recovery.
A Propeller That Doubles as a Hydrogenerator
The standout feature of EnergyMatic is its ability to switch into “REGEN” (Recharge) mode. Specifically developed for boats with 100% electric or hybrid propulsion, as well as those with endothermic engines equipped with a shaft alternator, the propeller can function as a powerful hydraulic turbine.
While under sail, the propeller rotates to drive the motor (acting as a generator), recharging the battery banks without the need for a separate, bulky hydrogenerator. Indicative regeneration levels for medium-to-small installations range between 0.6 kW and 1.8 kW at a speed of 7 knots. This is a vital solution for modern yachts, which are increasingly “energy-hungry” due to dual refrigerators, air conditioning, advanced chartplotters, and other onboard luxuries.
Innovative “Automatic Feathering”
Traditional feathering or folding propellers often require the skipper to stop the shaft, usually by turning off the engine and engaging reverse gear, to minimize drag. EnergyMatic eliminates this step.
Thanks to its ingenious automatic return mechanism, the blades position themselves in a “feathered” state (parallel to the water flow) without needing to lock the shaft. This is a critical advantage for boats with hydraulic transmissions or electric motors that lack a natural shaft brake. By reducing drag effortlessly, sailors can see a speed increase of up to 1.5 knots while under sail.
Performance and Precision Engineering
Despite its advanced energy-recovery capabilities, EnergyMatic remains a high-performance propulsion tool. It allows for micrometric pitch adjustment, enabling owners to fine-tune the propeller to their specific engine and hull, thereby increasing cruising speed and improving maneuverability during docking.
Like all EWOL products, EnergyMatic is built to last. It is crafted entirely from high-tech stainless steel superalloys (Super Duplex) with high concentrations of Chromium and Nickel. This ensures:
- Maximum mechanical strength.
- Exceptional resistance to galvanic corrosion.
- Long-term reliability in the harshest marine environments.
Versatility and Global Recognition
Founded in 1997, EWOL is a world-renowned leader in propeller technology, present across six continents. EnergyMatic is available in several versions to suit different vessel sizes:
- Orion (3 blades): Ideal for sailboats from 10 to 16 meters.
- Gemini and Pegasus (4 blades): Designed for larger yachts requiring higher thrust and stability.
The charging capacity is optimized based on the number of blades, propeller diameter, and the specific electric motor or software parameters used.
Conclusion
The EWOL EnergyMatic is more than just a propeller; it is a patented, global solution for the modern era of “Silent Sailing.” By combining the reduced drag of a feathering prop with the charging power of a turbine, it provides the autonomy and efficiency that today’s environmentally conscious sailors demand.
