Axis ART (AXIS Research Team) ART 899 hydrofoil front wing: 850 cm², 899 mm span, aspect ratio 9.76, with its closest equivalents from other brands within ±5% area and ±8% aspect ratio. Figures from Axis'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.
