UHA

(Ultra High-Aspect)

More glide, less effort, longer flow.

At its core, the UHA (Ultra High Aspect) is designed for efficiency. It gets you up on foil early, maintains momentum through long pumps, and carries speed effortlessly. The wide speed range allows for smooth linking of turns and waves, whether you are pumping, downwinding, or riding in light wind.

Who is it For?

Rider Level: Intermediate to Advanced.
Downwind Progression: Excellent for riders progressing in downwind foiling due to its low-end lift and high efficiency.
Ideal Goals: Staying on foil longer, covering distance, and riding with "flow" rather than aggressive turning.

Primary Disciplines

Downwind Foiling: Both powered conditions and true downwind.
Dock Starts & Pump: For long distance and efficiency.
Winging: Specifically for light wind conditions.

Comparison: Where it fits in the range

Compared To	The Feel	The Transition
VS. HA (High Aspect)	Similar predictable feel, but the UHA has more glide and is more locked in.	Natural: If you want more glide than your HA, this is the logical step.
VS. MA (Mid Aspect)	A significant step up in efficiency and speed range.	Learning Curve: Requires smoother inputs and a forward-focused riding style.

Sizing Guide

The UHA range acts as a sliding scale: Larger sizes prioritize early lift and glide; Smaller sizes prioritize speed and top-end efficiency.

1. The Large Sizes (1270 / 1070)

Focus: Early Lift, Light Wind, Maximum Glide.
Character: These get you up incredibly early and stay efficient through long flights. They feel very pitch-stable and "locked in" (less roll).
Best Suited For:
- Learning to Downwind SUP.
- Pushing the low-end limits of what is rideable.
- Dock starts and long-distance pumping.
- Light wind winging.

2. The Mid-Range (970 / 870 / 770)

Focus: The "Sweet Spot."
Character: Balances low-end lift with speed and control as conditions build. Stays predictable underfoot without being maximum span.
Best Suited For:
- Powered downwind runs.
- Dock start racing and faster pump sessions.
- Maximizing FoilDrive run times.
- Riders wanting efficiency without managing a massive wingspan.

3. The Small Sizes (670 / 570)

Focus: Speed & Top-End Efficiency.
Character: You sacrifice some early lift, but gain significant speed and control once flying. Geared toward experienced riders.
Best Suited For:
- High wind downwind conditions.
- Advanced pump and dock start sessions.
- Winging in gusty locations.
- Using with FoilDrive to keep the setup small but efficient.

How to Choose Your Size

Don't just look at the number printed on the wing; choose based on the feel you want.

If coming from an HA (High Aspect):

You will likely want to size down to the UHA. This allows you to maintain similar turning capabilities while gaining efficiency.

If your goal is pure Glide & Range:

You can stay on a similar size to your current foil. Be aware that the ride will feel more "locked in" and less focused on tight turns.

Summary: The UHA rewards smooth riding. It requires less aggressive input to keep you moving, allowing you to turn, connect, and flow.
