ORR-EZ is the ORA handicapping rule that has been created for regional racers. The initial expense and annual certificate fee to the boat owner are significantly lower than for a full measurement rule like ORR. Primary speed factors are determined from existing measurement databases of production boats and ORR certificates and simple sail measurements and data which is owner declared.
The data is run through our ORR-EZ VPP to produce polars, ratings and certificates. In some case where the boat design observed performance does not match the predicted performance, subjective corrections can be made by the National Rating Review Committee. Race organizers may select from customizable wind mixes to match the expected wind speed and degrees of upwind, downwind and reaching on the race course.
