Measurement & Certification

For measurement rules managed by US Sailing, the Offshore office manages and certifies all data inputs used in the rating process through the Universal Certification System (UCS). This requires a careful attention to detail and the coordination of contributions from owners, official measurers, sailmakers, designers, boatyards, and race organizers. Data management is paramount to ensure each boat has a rating that is suitable for fair competition. For more information about measurement and rating requirements, please visit our Rating Rules and Handicapping Systems page or contact offshore@ussailing.org.

A component of this is US Sailing being responsible for training official measurers for the Universal Measurement System (UMS) used by the IRC and ORC. Stationed around the country, these individuals are responsible for supplying accurate field measurements to the Offshore office.

ORC Certificate Type Policy

Any boat that is fully measured, and has a valid ORCi offset file, must request an ORC International certificate in order to have fully measured details (such as stability and righting moment) appear on their certificate. Should a boat not have an ORC approved Offset file, and are fully measured, their measurement data will still be used to calculate their rating, but the measurement data, including stability and righting moment, will not be printed on the ORC Club Certificate.
