The Formula

The measurement formula is given in the 2006 International Five Point Five Metre Rating Rules:

$5.500 \mbox{ metres} \ge 0.9 \cdot \left( \frac{L \cdot \sqrt{S}} {12 \cdot \sqrt{D}} + \frac{L + \sqrt{S}} {4} \right)$

where

= length for rating
= measured sail area
= displacement in cubic metres
