About Weenav

Weenav is a French start-up founded by three passionate engineers specialising in intelligent electric vehicles and information technology. Based in Roncq (Hauts-de-France), the company designs and integrates high-power electric and hybrid propulsion systems for new and existing boats. It is fully involved in the energy transition in the maritime and river sectors, offering clean, silent and high-performance solutions.

Our mission: to offer more sustainable, more comfortable and better controlled sailing, by reducing CO₂ emissions and the nuisances associated with combustion engines.

As well as designing its own engines - KRONOS (outboard) and ARION (inboard) - Weenav provides comprehensive support for its customers, including technical studies, custom integration, regulatory compliance, commissioning and monitoring tools.

Thanks to this global approach, Weenav is positioned as a key player in a rapidly changing market, with more than 35 million boats in circulation worldwide and a market potential estimated at 16 billion dollars over the next decade.
