Armstrong UHA Front Foil Wing

Pure glide. Endless connections. Next-level downwind efficiency.

The UHA Front Foil marks a major step forward in modern foil design from Armstrong Foils. Designed with a 12.6 aspect ratio, the UHA is built to maximize glide efficiency, reduce stall speed to an absolute minimum, and unlock effortless flow across bumps, flats, and transitions.

Whether you’re downwind foiling, parawinging, pump foiling, or doing flat-water paddle ups, the UHA transforms marginal energy into long, connected rides. This is a foil that doesn’t just extend sessions—it fundamentally changes how you ride them.

Why the UHA changes the game

Ultimate glide efficiency for downwind & parawing

The UHA’s ultra-high aspect ratio delivers exceptional lift-to-drag efficiency. Once flying, it holds speed with minimal input, allowing you to link bumps further apart and stay on foil through lulls where other foils drop out.

Perfect for:

• Downwind foiling

• Parawing downwind runs

• Ultra-efficient pump foiling

• Flat-water paddle-ups

• Long-distance glides with minimal fatigue

Pure Glide Efficiency

12.6 Aspect Ratio

With a 12.6 AR across all sizes, the UHA maximizes span efficiency while maintaining predictable control. The result:

• Extremely low stall speed

• Superior energy retention

• Longer, smoother glide phases

• Easy takeoffs relative to its size

This lets you focus on reading the ocean instead of fighting for speed.

Intuitive & Responsive

Turn, Connect, Flow

Despite its high aspect design, the UHA keeps the unmistakable Armstrong turning feel. Open your shoulders, look toward the next line, and the foil naturally follows. It rolls smoothly from rail to rail and maintains control even at low speeds—critical for technical downwind connections and pump transitions.

Built to last

Premium Carbon Construction

The UHA is constructed using pre-preg Toray high-modulus carbon fiber, engineered to handle extreme torsional and bending loads.
This results in:

• Exceptional stiffness

• Precise feedback under load

• Lightweight performance

• Long-term durability for high-stress disciplines like downwind foiling

Technology

A+ System

The UHA is fully compatible with Armstrong’s A+ System, creating a solid, unified connection between:

• Mast

• Fuselage

• Front foil

• Stabilizer

This integrated assembly delivers a smooth, quiet ride with zero play and maximum efficiency transfer from rider to foil.

Size Guide – Pick your UHA

Choosing the right size depends on rider weight, discipline, and conditions. Smaller sizes favor speed and stronger winds, while larger sizes excel in light wind, flat water, and paddle-ups.

The UHA isn’t about riding harder.

It’s about riding longer, smoother, and further—turning every ripple into forward motion and every session into continuous flow.

UHA Front Foil – How to Choose the Right Size

The UHA Front Foil is designed around glide, efficiency, and staying on foil for as long as possible. Choosing the right size isn’t just about numbers—it’s about how you want your sessions to feel, how much efficiency you’re chasing, and how stable or lively you want the foil under your feet.

Think of the UHA range as a continuous spectrum:
larger sizes prioritize early lift and maximum glide, while smaller sizes shift toward higher-speed efficiency and control.

Larger UHA Sizes: 1270 / 1070

These are the most glide-oriented options in the range. They lift incredibly early, remain efficient through long pump sequences, and feel extremely pitch-stable once flying.

Best suited for:

• Learning downwind SUP foiling and pushing the absolute low end

• Dock starts and extended pump sessions

• Light-wind winging

Expect a very locked-in, confidence-inspiring feel with reduced roll, paired with outstanding efficiency and range.

Mid-Range UHA Sizes: 970 / 870 / 770

For many riders, this is the sweet spot. You still get strong low-end lift, but with noticeably more speed and control as conditions become more powerful.

Best suited for:

• Powered downwind runs

• Faster dock starts and pump-focused sessions

• Riders who want high efficiency without committing to maximum span

• Light-wind winging

• Maximizing FoilDrive run time

These sizes strike a refined balance between glide and speed, remaining predictable and composed underfoot.

Smaller UHA Sizes: 670 / 570

The smaller UHA foils are all about speed and efficiency once you’re already flying. They still deliver impressive low-end lift for their size but truly shine at higher speeds and in stronger conditions. Best suited to experienced riders.

Best suited for:

• High-wind downwind runs

• Advanced pump and dock start sessions

• Winging in gusty or overpowered conditions

• Riders wanting maximum efficiency in a smaller foil for FoilDrive use

You’ll trade some early lift for increased top-end speed, precision, and control.

Final Thoughts

If you’re coming from an HA front foil and want a similar turning feel with noticeably more efficiency, you’ll generally want to size down when switching to the UHA.

If your primary goal is increased glide and a broader usable speed range, you can often stay close to your current size—just expect a more locked-in, glide-focused feel with less emphasis on tight turning.

The UHA Front Foil sits perfectly between raw efficiency and real-world usability. It rewards smooth input, gets you flying early, and keeps you gliding longer without aggressive pumping or constant corrections. If your sessions are about downwind flow, efficient pumping, and covering more distance with less effort, this is the natural next step.

Choose your size based on how you want to ride, not just the number on the foil.

Turn. Connect. Flow.
