F-One JAM HM Carbon 1400 · 1,200 mm span · traced from a photograph supplied to the project · drawn nose-up, wings aligned on the mid-point of the root chord (the dotted line). ▬ Armstrong APF (All-round Pump Foil) APF1350 · 1,202 mm

The JAM HM Carbon runs 3 sizes, 1,400–1,900 cm², and holds its proportions across the range: every size publishes an aspect ratio within 5% of the others.

Its 1,200 mm span is 9% wider than typical for the area — the median across the 88 current wings within 10% of its size is 1,098 mm.

Closest wings from other brands

Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
