From July 8 to 11, 2026, the Yacht Club de Monaco hosts the 13th edition of the Monaco Energy Boat Challenge (MEBC), the unmissable event for sustainable nautical innovation. Weenav, a French specialist in electric propulsion for boats, is proud to announce its participation in this major event with KRONOS, our 100% electric outboard motor.
The Monaco Energy Boat Challenge, a global showcase for maritime energy transition
Organized by the Yacht Club de Monaco under the presidency of H.S.H. Prince Albert II, with the support of the Prince Albert II of Monaco Foundation, UBS, BMW, and SBM Offshore; the MEBC has established itself over thirteen years as the largest open-air laboratory dedicated to alternative energies in boating. The challenge will bring together 43 teams from 21 nationalities across Europe, North America, the Middle East, and Africa, with over 1000 students and young engineers expected on the quays of the Yacht Club de Monaco.
For four days, participants will compete on the water through a demanding program: maneuverability tests, sea trials, speed records, endurance races, and slaloms. The event is now structured around several complementary categories: the Energy Class, the AI Class reserved for autonomous prototypes, the SeaLab Class, and the Open Sea Xperience, a category designed for zero-emission boats that are already certified and ready to sail.
It is precisely in this spirit of bridging innovation and real-world application, at the heart of the Open Sea Xperience category, that Weenav's approach is rooted.
Weenav and KRONOS: French-made electric power put to the test in Monaco
Designed and assembled in France, the KRONOS is the result of three years of research and development. Our range of 100% electric outboard motors covers a power range of 80 (59 kW) to 300 continuous horsepower (220 kW) and of 130 hp (96 kW) to 420 hp (300 kW) peak, designed to meet the needs of both recreational boaters and marine professionals.
Some features that make KRONOS an engine perfectly suited for this type of challenge:
- A monobloc and plug & play architecture : the engine integrates all essential components (power electronics, BMS, energy management co-developed with Garmin), limiting wiring to the bare essentials and facilitating installation in record time.
- Robust LiFePO4 batteries, designed by PowerTech Systems, IP67 waterproof, with an estimated lifespan of twenty to thirty years.
- Fast charging up to 22 kW (three-phase 32A), CCS Combo (up to 200 kW), allowing a charge from 20% to 90% in just 20 minutes under optimal conditions. A decisive advantage for boat rotation in continuous operation.
- Instantaneous torque and optimal maneuverability, offering immediate response to commands and precise trajectories, even at very low RPMs.
Why this participation matters to Weenav
Participating in the Monaco Energy Boat Challenge, for Weenav, is an opportunity to test our technology against the best talents and most innovative solutions in the nautical world, under real marine operating conditions. It also sends a strong signal to the industry: the 100% electric propulsion is no longer a laboratory promise, but a mature, reliable, and commercially available solution capable of competing with traditional internal combustion engines.
Beyond the competition, the MEBC is an excellent forum for exchange between students, engineers, shipyards, and industrialists, all committed to a common goal: accelerating the maritime sector's energy transition. Weenav sees it as an ideal showcase to demonstrate French expertise in electric marine propulsion, and to engage with the stakeholders shaping the future of sustainable yachting.
Our participation is also made possible thanks to the support of our sponsor PowerTech Systems, a recognised provider of lithium battery solutions. We would like to thank them for their trust and commitment alongside us throughout this adventure.
Join us from July 8 to 11 in Monaco
We will be present throughout the event to showcase KRONOS, engage with visitors, professionals, and electric boating enthusiasts, and share our vision for silent, high-performance, and emission-free navigation.
