Armstrong S1 Foil Kit Complete With Ronix Koal 727 Foil Board

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.
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.

Ronix Koal Surface 727 Foil Board

Buoyancy – In Ronix's many prototypes they found that the best boards were the ones that would barely want to rise when we were standing on them under water. As boards got too thick it was difficult to do a deep-water start – if the board was too thin you don’t have enough buoyancy when preparing to take off. The 727 has a balanced buoyancy unlike any surfer in our lineup.
