F-One EAGLE HM Carbon EAGLE 1290 hydrofoil front wing: 1,290 cm², 1,105 mm span, aspect ratio 9.50, with its closest equivalents from other brands within ±5% area and ±8% aspect ratio. Figures from F-One'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.
