Build hard Disciplines downwind, sup 2023
The Downwind has 3 sizes on record, discontinued sizes included, from 110 to 130 L. Its slenderness, 4.29, is greater than that of 88% 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 1.1× the tolerance.
