Family Phantasm PTM Brand’s category Surf / carve Disciplines wing, prone carbon · 2022
The closest current wings from other brands — every one within ±5% of area and ±8% of aspect ratio, ranked closest first. The closest with a traced outline, the Duotone Crest D/LAB 925 (#2), is already drawn over it. Select a numbered wing to draw it — up to three at a time.
The Phantasm PTM has run 9 sizes, 655–1,263 cm², including discontinued sizes, and changes proportion as it grows: aspect ratio runs 4.9 at one end of the range to 9.1 at the other, so its sizes differ in shape as well as in area.
Its 899 mm span is typical for the area: the median across the 135 current wings within 10% of its size is 900 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.
