Severne Hydro
Foil Race Board — Extreme performance for foil racing
The Hydro is the foil racing board built using advanced digital modeling technologies and innovative materials to push the limits in all foil racing disciplines. Designed to minimize hydrodynamic drag and maximize aerodynamic efficiency, it features a deep cockpit that guarantees total control in gybes, turns, and trim changes even at extreme speeds.
Deep, secondary cutouts reduce drag during takeoff and touchdown, providing stability and instant release from the water. Volume is optimally distributed across the entire profile for a low-drag configuration that allows for effortless top speeds while maintaining maximum balance even at high RPMs.
Ergonomic pads reduce foot fatigue; foot position and fit are designed for long-term performance.
Available in four sizes: 91, 85, 79, 73.
Ideal for maximum competitiveness in PWA and IFCA foil regattas.
