At this year’s International Multihull Show in La Grande Motte, a groundbreaking innovation in marine technology took center stage: JOOOL, a next-generation turnkey system designed for hybrid propulsion and onboard energy. Developed and manufactured in France by Alternatives Energies, JOOOL marks a significant shift toward sustainable, silent, and luxurious cruising.
With over 25 years of experience in marine electrification, the JOOOL team combines proven technology, plug-and-play simplicity, and advanced energy management in a system designed to remove energy constraints from sailing.
Already Setting Sail JOOOL is not a prototype—it’s already powering over 100 vessels worldwide, from dayboats to long-range catamarans. At the La Grande Motte show, three boats equipped with JOOOL systems will be on display:
- Fountaine Pajot Aura 51: Features 2x25kW POD motors, a 64kWh battery bank, and a 24kW genset, designed for charter operations in Naples.
- Leopard C46: A fully electric owner’s catamaran with 2x25kW POD motors, a 54kWh battery bank, and a 32kW genset.
- Yacht Concept Day One 80: A hybrid 80-foot day charter yacht that sails 100% electric in the protected Calanques region.
These vessels showcase the versatility of JOOOL, demonstrating everything from eco-friendly cruising in protected zones to reliable performance for charter operators.
The JOOOL System: Freedom in a Box At the core of the JOOOL system is the OneBox—a smart, compact energy management and conversion unit that integrates all onboard energy sources, including solar, wind, hydrogeneration, gensets, and shore power. With intuitive interfaces and real-time monitoring, JOOOL ensures a seamless cruising experience.
Key features of the JOOOL system include:
- Electric POD Propulsion: Quiet, efficient, and ready for hydrogeneration.
- Safe, Recyclable Lithium Iron Phosphate (LFP) Batteries: A sustainable power source.
- Smart Energy Propulsion Management System (EPMS): Features remote diagnostics for real-time performance insights.
- Streamlined Yard Installation: A simple and quick integration process, supported by a global service network.
- 7-Year Warranty and ISO-Certified Safety: Ensuring long-term reliability and peace of mind.
Designed for Builders, Loved by Sailors JOOOL’s fully modular, pre-configured system offers a one-stop solution for OEMs and shipyards, simplifying integration with short timelines. Trusted by major yards like Fountaine Pajot, Dufour Yachts, and Leopard Catamarans, JOOOL is quickly becoming a go-to choice in the industry.
For yacht owners, JOOOL offers more than just eco-friendly performance—it delivers independence, comfort, and an entirely new way to experience the ocean. Whether cruising silently into secluded coves, staying at anchor without relying on a generator, or enjoying an eco-conscious adventure, JOOOL sets a new standard for clean, connected sailing.
