Armstrong S1 Foil Kit: Redefining how we learn to foil. 

 

Armstrong are redefining how we learn to foil, making the sport accessible to everyone. 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.


  • An ultra easy platform for first time flyers to learn any foiling discipline. Excellent low speed lift, stability and recovery from ventilation.
  • Fully compatible with all Armstrong with the extensive Armstrong range
  • 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.

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.

Front/Stabiliser Foils

  • 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.

Mast/Fuselage

  • Hexagonal fuselage shape is inherently strong, stiff and modular for an easy front foil swap.
  • The mast section is 17.5mm thick; efficient through the water, yet strong to withstand the loads of advanced riding.
  • Aircraft-grade 6061 and 7075 alloys for excellent strength to weight ratio.
  • Titanium and stainless hardware save having to disassemble frequently so it’s easy to use and maintain with excellent corrosion resistance. Screws are custom-made M7 and M8 x 1.25.
