Armstrong Performance Mast 865mm – Premium Carbon Mast for Ultimate Foiling Control

The Armstrong Performance Mast 865mm is a high-end hydrofoil mast engineered to deliver exceptional stiffness, efficiency, and control across a wide range of foiling disciplines. Designed with input from elite riders and America’s Cup foil engineers, this mast sets a new benchmark for performance in hydrofoil surf wing, wing foiling, foil surfing, and wind foiling.

With its versatile 865mm length and advanced carbon construction, it is widely considered the “do-it-all” mast for riders looking to balance speed, maneuverability, and stability in various conditions.

Designed for All Foiling Disciplines

The 865mm length hits the sweet spot for versatility, making it suitable for nearly every foiling style. Whether you’re riding waves, cruising flat water, or pushing limits in strong winds, this mast adapts seamlessly.

It is recommended for:

• Wing foiling progression
• Hydrofoil surf wing sessions
• Foil surfing and prone riding
• Wind foiling in high wind conditions
• Downwind and tow foiling

This versatility is why the 865mm size is often described as the “one mast quiver” option for riders seeking a single solution across disciplines.

Advanced Carbon Construction for Maximum Performance

At the core of the Armstrong Performance Mast is its premium construction using Toray high modulus carbon fiber, delivering a unique balance of stiffness, strength, and lightweight performance.

Construction highlights:

• High modulus (HM) carbon for stiffness
• Intermediate modulus (IM) carbon for durability
• Optimized laminate structure for load distribution
• Lightweight yet extremely strong design

This combination ensures minimal flex, which translates into more direct energy transfer and improved responsiveness underfoot.

Compared to standard masts, this results in:

• Better control at high speeds
• More precise turns and carving
• Enhanced pumping efficiency

Engineered for Speed, Efficiency, and Reduced Drag

One of the defining features of the Performance Mast 865 is its hydrodynamically refined shape, developed using advanced CFD (Computational Fluid Dynamics) analysis.

Performance benefits:

• Reduced drag for higher top speeds
• Improved water flow for smoother rides
• Minimized ventilation during aggressive riding

Every section of the mast—from the base plate to the fuselage connection—has been optimized for maximum efficiency, allowing riders to maintain speed effortlessly across different conditions.

Superior Stiffness for Ultimate Control

Stiffness is one of the most important factors in foil mast performance, and the Armstrong Performance Mast excels in this area.

Advantages of high stiffness:

• Immediate response to rider input
• Greater stability in choppy water
• Improved confidence at speed

The stiff central strut reduces unwanted flex, ensuring that the foil remains stable even under heavy loads or during high-speed maneuvers.

This is particularly beneficial for:

• Advanced wing foil riders
• High-speed wind foiling sessions
• Aggressive carving in waves

Optimized Mast Rake for Better Ride Feel

The mast features a built-in 1-degree rake angle, a subtle yet impactful design element that enhances overall ride performance.

Benefits of mast rake:

• Reduces drag for easier take-offs
• Improves comfort and ride balance
• Makes landings smoother and more forgiving
• Helps prevent nose-diving at high speeds

This design ensures that the board sits at a more optimal angle relative to the foil, improving both efficiency and rider comfort.

Premium Hardware and Build Quality

Armstrong includes top-tier hardware with the Performance Mast 865, ensuring durability and reliability in harsh marine environments.

Included components:

• Titanium-plated screws
• Stainless steel hardware
• Precision-engineered base plate
• Protective transport bag

These materials not only reduce weight but also offer excellent corrosion resistance, ensuring long-term performance.
