GONG Ypra Surf-Freestyle V3 XS hydrofoil front wing: 560 cm², 630 mm span, aspect ratio 7.09, with its closest equivalents from other brands within ±5% area and ±8% aspect ratio. Figures from GONG's own published specifications.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a match inside the area tolerance may be comparing unlike figures.

The brand's published aspect ratio contradicts its own span and area by more than 10%, so the geometric figure (span² ÷ area) is used instead and the row is filed as a brand data error.
