About the Rule: ORR is an objective rule whose rating calculations are based on the measurement of all the speed-related features of the competing sailboats. Developed through systematic scientific research, the ORR Velocity Prediction Program (VPP) calculates the speed potential of each boat at various combinations of wind speeds and course directions to give the fairest handicap possible.

ORA intends for the ORR handicap system to be a non-type forming measurement rating rule that fairly evaluates well designed and prepared boats. The ORR is not a development rule and is not intended for sailors who are looking to “beat” the ORR handicap system. In order to discourage attempts to design boats “to the rule”, the algorithms of the VPP are not publicly broadcast. ORA updates the ORR Rule Book and handicap system on a regular basis to stay current with the latest VPP research and boat design development.
