Armstrong S1 300 Stabiliser – Precision Stability for Progression and Performance

The Armstrong S1 300 Stabiliser is a purpose-built rear wing designed to deliver exceptional balance, control, and predictability across all foiling disciplines. Engineered as part of Armstrong’s Step 1 (S1) range, this stabiliser is tailored to help riders progress quickly—from their very first lift-offs to confident carving and advanced manoeuvres. Whether you’re into hydrofoil surf wing setups, wing foiling, wing foil riding, foil surfing, or wind foiling, the S1 300 offers a forgiving yet high-performance ride that adapts seamlessly to your level.

Designed for Stability, Control, and Easy Progression

The Armstrong S1 300 Stabiliser stands out because of its beginner-friendly yet performance-capable design. Developed alongside the S1 front foils, it creates a highly intuitive and stable foiling platform that minimizes the learning curve.

Its low-mid aspect ratio outline combined with a high camber foil section ensures excellent lift at low speeds, making take-offs smoother and more predictable. This is especially beneficial for beginners in wing foiling or foil surfing who need stability during early sessions.

Additionally, the stabiliser features a subtle gull-wing rondure, which helps maintain water contact when riding close to the surface—reducing the risk of sudden breaches and improving overall control.

Advanced Hydrodynamics for Smooth Ride Feel

Armstrong has engineered the S1 300 with refined hydrodynamics to ensure a balanced ride across a wide speed range. The stabiliser maintains pitch stability while allowing smooth transitions between turns and direction changes.

Key design elements include:

• Leading and trailing edge sweep for enhanced stability
• Optimized chord length for consistent lift distribution
• Downturned wing tips for improved safety and water flow efficiency
• Reduced drag profile for better glide and speed

These features combine to create a stabiliser that feels almost “autopilot-like,” offering predictable control even in challenging conditions.

Built with Premium Carbon Construction

Durability and performance go hand in hand with the S1 300. Constructed using high-quality carbon composites, this stabiliser delivers an excellent strength-to-weight ratio, ensuring both rigidity and responsiveness.

Benefits of the carbon build include:

• High torsional stiffness for precise control
• Lightweight feel for improved manoeuvrability
• Long-lasting durability under repeated stress
• Consistent performance across all conditions

This robust construction ensures that the stabiliser maintains its shape and performance even under heavy loads, making it ideal for both beginners and experienced riders.

Optimized for Multiple Foiling Disciplines

The Armstrong S1 300 Stabiliser is highly versatile, making it suitable for a wide range of foiling styles:

• Hydrofoil surf wing setups for wave riding
• Wing foiling sessions in light or strong winds
• Wing foil progression from beginner to intermediate
• Foil surfing in small to medium waves
• Wind foiling with stable control at varying speeds

Its forgiving nature allows beginners to build confidence, while its responsive design supports advanced riders looking to push their limits.

Key Features at a Glance

• 300 cm² surface area for balanced lift and control
• Mid aspect ratio (5.7) for stability and efficiency
• 410 mm wingspan for optimal manoeuvrability
• High camber profile for low-speed performance
• Gull-wing shape for improved surface control
• Downturned tips for added safety
• Armstrong A+ System compatibility for secure connection

These features make it one of the most reliable stabilisers for progression in modern foiling.
