Disciplines prone, efoil
The Zapple S Riift has 7 sizes in the current range, from 24 to 43 L. Its slenderness, 2.92, is greater than that of 49% 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 1.3× the tolerance.
