Family Momentum Brand’s category Downwind Disciplines downwind, wing, sup UHM carbon · 2025
The MOMENTUM UHM runs 5 sizes, 516–916 cm², and holds its proportions across the range: every size publishes an aspect ratio within 5% of the others.
Its 926 mm span is 36% wider than typical for the area — the median across the 44 current wings within 10% of its size is 680 mm.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
