Armstrong AlloyNew

The alloy package builder offers a guided shopping experience to assemble your custom foil kit instead of buying a pre-configured package.

Build Custom Alloy package

The Armstrong Alloy System and S1 Foil range was designed with one thing in mind:

CREATE THE EASIEST PATHWAY FOR MORE PEOPLE TO EXPERIENCE FOILING

The Armstrong 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.

It's not alloy, it's Armstrong Alloy.

The Armstrong Alloy System surpasses all expectations of what an alloy hydrofoil can be. Its advanced section design and exceptional quality empowers riders to progress without limits, and the system's compatibility with all Armstrong's foil ranges encourages endless experiences on the water.

Elevating Alloy

Design that's far from price point.

Building on the knowledge and technology used to develop Armstrong's industry-leading Performance carbon mast, the AA mast section and structure are optimised from top to bottom for an excellent balance of strength, efficiency and weight. A specially machined mast top and SailGP-inspired bottom bracket design exemplify the attention to detail put into this system that maximises performance and minimises compromise. The mast and fuselage are crafted from 6061 and 7075 alloy for excellent strength and weight properties where needed most.

Modular As Standard

One system, endless experiences.

The Alloy fuselage is fully compatible with all our foils and stabilizers so riders at any stage in their foiling journey can easily adjust their ride as desired.

Premium Hardware

Embodying the Armstrong ethos.

The AA System is outfitted exclusively with premium titanium and stainless steel hardware so your setup can continue growing with you over time. Custom titanium M7 x 1.25 and M8 screws provide a strong, corrosion-resistant connection with a fit and finish that's worthy of the Armstrong name.

S1 FOILS

REDEFINING THE APPROACH TO FOILING

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.

AUTOPILOT-LIKE STABILITY

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.

FORGIVING AND VERSATILE

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.

PREMIUM CONSTRUCTION

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.

After 6 months experience with the S1 Alloy

After 6 months experience with the S1 Alloy Package system I'm beginning to realize how special and well thought out this system is. As a beginner, I have found that the hype is true. You'll find out that the foils (I have 3) and the fuselage length will actually help you get up and going toward learning this difficult sport. I took a spill (and you will too) and landed on the tip of the foil (hopefully you won't). I now appreciate the square down turned tips. On foil it's steady. Described as "self correcting" on breaching is a true statement. I wouldn't consider it a beginner setup that you'd grow out of quickly. It mostly holds your hand till you can learn. When you're ready to demand more, it delivers. It can go fast and it can turn sharply. It performs, without surprises. For the price of entry into an expensive sport, and the fairly priced accessories, and excellent build quality, AND the ability to add the more advanced foils in the Armstrong line up, make this a worthy consideration.Maybe even a "no brainer". I'm glad I bought the S1 and finally got into learning this insane sport.
