Build hard Disciplines windfoil 2024
The Foil X has 3 sizes on record, discontinued sizes included, from 105 to 145 L. Its slenderness, 2.69, is greater than that of 33% 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. Boards for wake, eFoil, kite or windfoil alone are compared only with each other.
None of these is within the tolerances above: each misses on volume, length or slenderness by up to 2.3× the tolerance.
