The formula

The measurement formula is given in the 2021 International Five Metre Rating Rules:

[math]\displaystyle{ 5.000 \mbox{ metres} = \frac{L + \sqrt[2]{S} - F - \frac{B} {2}} {2} }[/math]

where

  • [math]\displaystyle{ L }[/math] = length for rating (as defined by rule 3.4)
  • [math]\displaystyle{ S }[/math] = measured sail area
  • [math]\displaystyle{ F }[/math] = freeboard in metres (as defined by rule 3.5)
  • [math]\displaystyle{ B }[/math] = width in metres (as defined by rule 3.6)
