GONG X-Over V3 Atmo XL hydrofoil front wing: 1,410 cm², 950 mm span, aspect ratio 6.40, 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.
