The Ace Foil has 10 sizes on record, discontinued sizes included, from 85 to 140 L. Its slenderness, 4.07, is greater than that of 87% of the 1,895 current boards that publish a length and a width.
No current board from another brand is within ±7% of volume and ±2% of length, and ±2% of slenderness where both publish a width of this one.
None of these is within the tolerances above: each misses on volume, length or slenderness by up to 1.5× the tolerance.
