The Wassup Foil E-Tech Y25 has 2 sizes in the current range, from 134 to 154 L. Its slenderness, 3.20, is greater than that of 61% 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.
