$R={\frac {0.2\cdot L\cdot {\sqrt {S}}}{\sqrt[{3}]{D}}}$

Muutujad:

• L - Boat length - paadi pikkus
• S - Sail area - purjepind
• D - Displacement - tonnaž (http://en.wikipedia.org/wiki/Tonnage)
• R - Rating - võistlusväärtus

$8meetrit={\frac {L+B+1/2G+3d+1/3\cdot {\sqrt {S-F}}}{2}}$

• m B = Beam in linear units
• m L = Length in linear units
• m G = Girth in linear units
• m d = Girth difference in linear units
• m S = Sail area in square units
• m F = Freeboard in linear units

$8meetrit={\frac {L+1/4G+2d+{\sqrt {S-F}}}{2,5}}$

2000:
$8meetrit={\frac {L+2d-F+{\sqrt {S}}}{2,37}}$

• L = Length in metres
• d = Girth difference in metres
• F = Freeboard in metres
• S = Sail area in square metres

$Rating={\frac {L+2d-F+{\sqrt {S}}}{2,37}}.$

• L = Length in metres
• d = Girth difference in metres
• F = Freeboard in metres
• S = Sail area in square metres

$5,500meetrit=>0,9\cdot \left({\frac {L\cdot {\sqrt[{2}]{S}}}{12\cdot {\sqrt[{3}]{D}}}}+{\frac {L\cdot {\sqrt[{2}]{S}}}{4}}\right)$

• L = Length for rating (rule 3)
  
• S = Measured sail area (rule 16)
  
• D = Displacement in cubic metres. This shall be taken as the weight (kg) when the yacht is first measured or when it is re-weighed for subsequent revalidation's, divided by 1025.
