Located in Cape Hatteras. No bots.The S1 (Step 1) foils deliver remarkable stability, ultra low flying speed and an instantly intuitive feel to make the first step into foiling as accessible and approachable as possible.
Pitch, roll and yaw stability are critical to success when building folding 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 Step 1 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.
Built to the same tolerances as our other foils, the S1 range is constructed from carbon composites which provide an excellent strength to weight ratio.
