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.
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.
UHA Front Foil - How to Pick Your Size
The UHA Front Foil is all about glide, efficiency, and staying connected for longer. The key to picking the right size comes down to what kind of riding you want to do, how much efficiency you’re chasing, and how locked in you want the foil to feel.
To put it simply, think of the UHA range as a sliding scale between early lift and maximum glide at the bigger sizes, and higher speed efficiency as you size down.
Bigger UHA Sizes: 1270 / 1070
These are your early lift, light wind, and glide-focused options. They get you up incredibly early, stay efficient through long pump flights, and feel very pitch-stable once flying.
Best for:
Learning to Downwind SUP, as well as pushing the low end of what you can ride in
Dock starts and pump sessions
Light wind winging
Expect a more locked-in feel with less roll, but huge efficiency and range.
Mid-Range UHA Sizes: 970 / 870 / 770
This is the sweet spot for many riders. You still get excellent low-end lift, but with more speed and control as conditions build.
Best for:
Powered downwind runs
Dockstart racing and faster pump sessions
Riders who want efficiency without going full max span
Light wind winging
Maximising your FoilDrive run time
These sizes balance glide and speed while staying predictable underfoot.
Smaller UHA Sizes: 670 / 570
These are all about speed and efficiency once you’re already flying. still have great low end for their size, more top and best suited to experienced riders.
Best for:
High wind downwind
Advanced pump and dock start sessions
Winging in gusty locations
Gaining efficiency while having a small foil for FoilDriving
You’ll give up some early lift but gain speed and control at the top end.
Overall
If you’re coming from an HA and want similar turning with more efficiency, you’ll likely want to size down when moving to the UHA.
If your main goal is simply more glide and a wider speed range, you can often stay on a similar size, with the understanding that the feel will be more locked-in and less turn-focused.
The UHA Front Foil sits right between efficiency and usability. It rewards smooth riding, gets you up early, and keeps you gliding longer without needing aggressive inputs. If your sessions are about downwind flow, efficient pumping, and covering more ground with less effort, this is the next step. Pick your size based on how you want your sessions to feel, not just the number printed on the foil.
