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.

Beyond this, US Sailing is 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.
