Our project aims to develop a high-performance solar-hydrogen foiling boat designed for efficient, zero-emission navigation. The vessel accommodates one pilot and two passengers, reaches a top speed of 35 knots, and offers a range of 160 km. Its innovation lies in a hybrid hull structure combining okoumé plywood and carbon fibre, reducing manufacturing emissions by 85% compared with conventional composites. The propulsion system integrates the motors directly into the torpedoes, enabling a direct connection to the propellers and minimising mechanical losses. The project aims are to compete in the Monaco Energy Boat Challenge to benchmark our technology against the best zero-emission prototypes and complete a full circumnavigation of Lake Geneva (160 km) to demonstrate real-world reliability, endurance, and energy efficiency.
