The formula
The measurement formula is given in the 2021 International Five Metre Rating Rules:
![{\displaystyle 5.000{\mbox{ metres}}={\frac {L+{\sqrt[{2}]{S}}-F-{\frac {B}{2}}}{2}}}](http://wikimedia.org/api/rest_v1/media/math/render/svg/89dfdab4c57c38ec96112db7571272e963921b62)
where
- = length for rating (as defined by rule 3.4)
- = measured sail area
- = freeboard in metres (as defined by rule 3.5)
- = width in metres (as defined by rule 3.6)
