Armstrong UHA 870 Foil Front Wing A+

Pure Glide Efficiency

The UHA represents the next chapter in foil progression. A foil that not only extends your sessions but also transforms them. With a 12.6 aspect ratio, riders experience ultimate glide efficiency, incredibly low stall speed and the intuitive Armstrong turning feel that defines the brand. The UHA turns the ocean into one continuous playground, where every bump, every line and every section becomes part of an unbroken flow. 

12.6 Aspect Ratio

With a 12.6 aspect ratio, the UHA is optimised for ultra-efficient glide and minimal drag. The high span-to-chord ratio increases lift-to-drag efficiency, allowing the foil to maintain speed with less input and achieve a lower stall speed. This results in longer lines, smoother connections, and superior energy retention across bumps.

Turn, Connect, Flow

This foil allows riders to open their shoulders, look ahead to the next bump, and feel the foil naturally follow. It's intuitive and responsive.

 

Built to last

Foils experience extreme torsional and bending loads, which is why we've crafted the UHA from premium pre-preg Toray high modulus carbon fiber. It results in an ultra-strong, stiff, and lightweight foil that performs exceptionally.

Technology

The A+ System is our proprietary foil assembly design that joins the mast, fuselage, front foil and stabilizer together for a solid and smooth feeling on the water.
