Armstrong Step 1 - The S1 Aluminum Hydrofoil System

One System, Endless Possibilities

Redefining how we learn to foil.

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.

Kit is paired with 72cm Alloy mast, 75cm Alloy fuselage, S1 300 stabiliser, kit bag.

Details

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.

THE ALLOY SYSTEM WAS DESIGNED TO ENABLE RIDERS OF ALL SKILL LEVELS TO CHASE ENDLESS EXPERIENCES ON THE WATER. ITS MODULARITY, BROAD PERFORMANCE RANGE AND EXCEPTIONAL BUILD QUALITY EMPOWERS RIDERS OF ALL LEVELS TO PROGRESS WITHOUT LIMITS.

Modularity is core to the Alloy System design. It’s fully compatible with all our front foils and stabilisers so you as your riding evolves, so can your setup. Building on the knowledge and technology that led to our industry-leading carbon Performance Mast, the AA mast shape and structure are optimised 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 aluminium 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.
