Unifoil Progression 170 Progression 170 hydrofoil front wing: 1,097 cm², 953 mm span, aspect ratio 8.30, 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.
