PolyBoat Nantes is a student association based at Polytech Nantes, the engineering school of the University of Nantes in France. Founded in 2025, the team focuses on the design and development of innovative, sustainable marine propulsion systems, with a particular emphasis on hydrogen and electric technologies. In just one year it has grown from 8 to 24 members, bringing together students from a wide range of engineering disciplines who take on every stage of the boat, from propulsion and energy systems to structure and onboard electronics. Driven by a shared commitment to teamwork, technical excellence and environmental responsibility, PolyBoat Nantes learns by designing, building and racing its own prototype, turning hands-on maritime engineering into real, competition-ready results. Building on the experience of its first participation, the team approaches MEBC 2026 with a clear ambition: to convert a year of development into reliable, high-performance racing.
