Sroka S-Foil 1190 L HA 1190 L HA hydrofoil front wing: 1,190 cm², 910 mm span, aspect ratio 7.50, with its closest equivalents from other brands within ±5% area and ±8% aspect ratio. Figures from Sroka'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 publishes this aspect ratio, but its own span and area (span² ÷ area) give a figure 5–10% away. The published number is kept and marked.
