Armstrong S1 (Step 1)



All foil sports for beginner-intermediate riders.


Redefining how we learn to foil, the Step 1 (S1) foil range delivers remarkable stability, ultra low flying speed and an instantly intuitive feel to make the first step into foiling as accessible and forgiving as possible.

Pitch, roll and yaw stability are critical to success when building foiling skills. The S1 design achieves a near autopilot-like level of predictability thanks to a combination of leading and trailing edge sweep, chord length and foil section geometry. The result is an ultra easy platform for first time flyers to learn any foiling discipline.

The S1 foils fly at a remarkably low speed with a high degree of controllability so that riders can practise manoeuvres with less risk and a lower learning curve. When overpowered, the foil reduces breaching with a tendency to fly itself back down when approaching the surface. Because these foils handle speed and ventilation so well, riders can enjoy an exceptionally broad usable speed range in each size. Downturned wingtips provide an extra element of safety.


  • An ultra easy platform for first time flyers to learn any foiling discipline. Excellent low speed lift, stability and recovery from ventilation.
  • Leading and trailing edge sweep for stability and a narrower span to minimise breaching.
  • Downturned wing tips increase rider safety and improve the efficiency of water flow.
  • Proprietary Armstrong A+ System foil connection design offers industry-leading stiffness, durability and modularity.
  • The S1 300 stabiliser was designed alongside the S1 foils to provide riders with the best learning platform possible.
