Windsurf Hydrofoils

F4 has designed the first windsurfing foils that were faster than conventional boards around the race course. This has led to a revolution in our sport. We are pleased to work with the top riders on the PWA on race foils.

Our foils are made with solid high modulus (HM) carbon fiber with layups and orientations designed for stability and speed. This means stiff and thin. Our windsurf foil masts are under 13mm thick!



F4 is pleased to announce new foils for windsurfing based on new high modulus masts and aluminum fuselages. This modular system allows for both existing and new wings to be adapted to different geometry and spacings. Changing the fuselage length and front wing spacing can optimize upwind vs. downwind vs. reaching performance.

  • 90cm fuselage for control downwind and reaching
  • 100cm fuselage for medium to high wind race performance
  • 120cm fuselage for max upwind and light air performance

– 80cm or 90cm front wing

– 38cm rear wing with interchangeable 3d angle of attack spacer
