Seair

SEAir is a French group pioneering hydrofoil technology for the next generation of naval platforms. Our vessels fly above the water — faster, farther, and more stable — combining efficiency, discretion, and resilience for defense, sovereignty, transport, and yachting applications. Born from a decade of research and real-world trials, SEAir has become a reference in manned and unmanned foiling vessels, from naval drones to high-performance and eco-conscious chase boats and tenders. Our retractable foil systems and electronic flight controls drastically reduce fuel consumption, wake, and crew fatigue, while doubling range and maintaining high-speed stability in rough seas. We operate at the crossroads of deeptech, naval architecture, and European defense innovation. Our platforms are designed as modular systems, ready to host sensors, communication suites, and autonomous capabilities — enabling hybrid and unmanned operations for tomorrow’s fleets. Strategic programs • A €3M fundraising is underway to accelerate industrial deployment and European partnerships. • SEAir leads a European Defense consortium, funded by the European Defence Agency (€8M), to design, build and qualify a 12-meter dronized foiling vessel — a true operational breakthrough. • Continuous collaborations with European navies, research centers, industrial primes, and shipyards to extend performance and mission capabilities across sectors. Our vision To make SEAir the global reference in foiling naval platforms, shaping a faster, farther, stealthier, and more stable future for mobility at sea — from defense operations to high-performance and eco-conscious chase boats and tenders.
