ORC International

ORCi is based on a complete boat measurement carried out by an official ORC Measurer as defined by the Universal Measurement System. The hull and appendages must be measured and the offset file approved by ORC to meet ORCi standards. 

This is the most accurate rating the rule system offers. These certificates are intended for use in World, Continental, Regional, and National level races. ORC International certificates comes in four A4 pages. The first page gives a general presentation of the boat with its rated boat speeds, in addition to the main hull, propeller, rig and sail measurements.It also contains information needed to enter the race like crew weight, limitations on use of sails, and stability index with the rated righting moment.

The second page is presenting scoring options in two sections: default scoring options that are present on each certificate and other scoring options that are selected for use by the relevant National Rating office.

The third page is showing a detailed list of measurements of the Hull and appendages, propeller, rig, flotation, stability, and the measurement inventory. The fourth page is reserved for measurements within the sails inventory.

More details are given in the measurement and scoring sections, while complete definitions can be found in the appropriate rules documents.
