GONG Fluid H V3 FG 3XS hydrofoil front wing: 510 cm², 650 mm span, aspect ratio 8.40, 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.
