Duotone Carve 3.0 D/LAB 500 hydrofoil front wing: 500 cm², 610 mm span, aspect ratio 7.40, with its closest equivalents from other brands within ±5% area and ±8% aspect ratio. Figures from Duotone'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.
