La Grande Motte, France – April 23, 2025 — JOOOL, a new brand developed by France’s Alternatives Energies, has launched its next-generation hybrid propulsion and smart energy systems at the International Multihull Show in La Grande Motte.
Designed for motorboats and power catamarans, JOOOL combines proven electric propulsion technology with smart energy management. Built on 25 years of experience in marine electrification, the system offers turnkey installation, modular design, and efficient, quiet operation.
Already installed on over 100 vessels worldwide, JOOOL will be showcased on the Yacht Concept Day One 80—a hybrid 80-foot day charter yacht operating 100% electric in the Calanques region.
At the core of the system is the JOOOL OneBox, an integrated, compact unit managing all onboard energy sources including solar, genset, and shore power. Key features include electric POD motors, recyclable lithium iron phosphate (LFP) batteries, and a Smart Energy Propulsion Management System (EPMS) offering real-time monitoring and remote diagnostics.


JOOOL’s systems are supported by a global service network, offer a 7-year warranty, and meet ISO-certified safety standards. Designed for shipyards and OEMs, JOOOL systems simplify integration and reduce installation time, making them an attractive option for motorboat builders and owners seeking efficient, clean cruising.
JOOOL is already trusted by major shipyards and has extensive experience delivering power solutions under the Alternatives Energies brand.
