Axis HPS (High Performance Speed) HPS 650 hydrofoil front wing: 769 cm², 650 mm span, aspect ratio 5.49, 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.

The brand's published aspect ratio contradicts its own span and area by more than 10%, so the geometric figure (span² ÷ area) is used instead and the row is filed as a brand data error.
