Duotone Spirit GT 700 700: a legacy wing, no longer in Duotone's current range. 700 cm², 655 mm span, aspect ratio 6.13. The current wings that match it within ±5% area and ±8% aspect ratio, from Duotone'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.
