GONG Ypra Slalom V3 Atmo M hydrofoil front wing: 800 cm², 840 mm span, aspect ratio 8.90, 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.
