Unifoil Progression 100 Progression 100 hydrofoil front wing: 645 cm², 824 mm span, aspect ratio 10.50, with its closest equivalents from other brands within ±5% area and ±8% aspect ratio. Figures from Unifoil'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.
