Family Sea Devil Chord 520 mm Brand’s category All-round / freeride Disciplines wing, pump, sup, downwind full carbon monocoque · 2025-2026
The Sea Devil runs 3 sizes, 2,122–2,742 cm², and changes proportion as it grows: aspect ratio runs 3.3 at one end of the range to 5.6 at the other, so its sizes differ in shape as well as in area.
No current wing from another brand is within ±5% of area and ±8% of aspect ratio of this one.
None of these is within the tolerances above — each misses on area, on aspect ratio, or on both, by up to 2.5× the tolerance.
