An industrial solution designed for series production
Officially launched in April 2025, JOOOL is not a pilot project. The system already equips more than a hundred units, positioned in different segments: from long-term charters to owner-operated units, right up to tourist vessels operating in environmentally sensitive areas. This early deployment demonstrates a high level of industrial maturity.
The heart of the system is the OneBox: a centralized energy management unit that controls all available sources âeuros solar, hydro, wind, genset and wharf âeuros while ensuring stable distribution monitored in real time.

Several operating configurations
Three catamarans equipped with JOOOL systems were presented at the 2025 show:

-
Visit Fountaine Pajot Aura 51 for rental in Naples, equipped with two 25 kW POD motors, a 64 kWh battery pack and a 24 kW generator.
-
Visit Leopard C46 proprietary version, with all-electric propulsion, 54 kWh batteries and 32 kW generator.
-
Visit Day One 80 yacht Concept, an 80-foot yacht for coastal navigation in the Calanques, designed for emission-free operation in protected areas.
Each of these cases illustrates the flexibility of the system architecture and its ability to meet the requirements of a variety of programs.
A tool designed for construction sites and integrators

One of JOOOL's strengths lies in its modular design. Components are pre-configured to simplify shipyard integration, reducing commissioning times. Compatible with ISO standards, the system comes with a seven-year warranty and includes a remote monitoring interface with on-board diagnostics. This level of support also facilitates after-sales follow-up and strengthens the argument with charter professionals or demanding owners.
Main technical data
Propulsion is based on electric PODs with passive hydrogeneration, combined with LFP (lithium-iron-phosphate) batteries, which are safer and more recyclable. The EPMS (Energy Propulsion Management System) coordinates all flows and enables continuous optimization of consumption, both when sailing and at anchor. Electrical safety is ISO-certified, and the service network is being rolled out worldwide to support the brand's growth.
JOOOL has established itself as a credible industrial response to the energy transformation of the boating industry. Its technical proposal is aimed primarily at boat builders and equipment manufacturers seeking to integrate sustainable solutions without completely overhauling their architecture. Faced with the new expectations of offshore and inshore yachting, particularly in sensitive or protected areas, JOOOL represents a complete alternative, ready to equip future generations of hybrid catamarans.
