Armstrong S1 Complete Foil Set 

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 practice maneuvers 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.

Built to the same tolerances as other Armstrong foils, the S1 range is constructed from carbon composites which provide an excellent strength to weight ratio.


  • 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 minimize 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 stabilizer was designed alongside the S1 foils to provide riders with the best learning platform possible.

Modularity is core to the Alloy System design. It’s fully compatible with all Armstrong front foils and stabilizers so as riders’ style evolves, so can their setup. Building on the knowledge and technology that led to Armstrong's industry-leading carbon Performance Mast, the AA mast shape and structure are optimized from top to bottom for an excellent balance of efficiency and strength. This approach to design and attention to detail is exemplified in the Alloy System’s specially machined mast top and SailGP-inspired bottom bracket that are crafted from aerospace-grade aluminum alloys. 

The system is outfitted exclusively with premium titanium and surgical stainless hardware for a light and highly corrosion resistant setup that’s durable over time. Industry-leading manufacturing tolerances make for a high performance, beautiful fit and finish overall. 


  • 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.

Kit Includes: (S1 Front Foil, Alloy 72cm mast, Alloy 75cm Fuselage, S1 300 stabilizer, All Hardware, and Traveling bag)
