As a result of having the complete matrix of predicted boat speed at various wind strengths and directions, ORC rating systems can therefore provide a variety of methods to calculate corrected time. Scoring options offered include the most sophisticated, where the boat's performance is taken in consideration depending on the wind conditions, but also simple scoring options using single number scoring coefficients in either Time on Time or Time on Distance formats. Simple scoring options also include the Triple number system that uses three different Time on Distance or Time on Time coefficients to be used in light, medium and heavy breezes. All simple scoring options are also given for either Windward / Leeward racses (50% beat, 50 % run) or Coastal / Long distance races (Different percrentages of beat, reach and run).
This wide variety of scoring options may look complex, but it is actually one of the strength of the ORC rating systems to offer race managers a variety to choose from that best suits their fleet, their race type and their race conditions. The factors race managers should consider when choosing which scoring type to use include:
Because the ORC VPP can predict the performance
potential of different boat types, it can rate them fairly against
each other in any range of wind conditions and course types. In this
Curve Scoring can make handicap yacht scoring significantly
more fair than any single number scoring approach.
