  • ORC Club v. ORC International

    ORC Club - certificates do not require verified measurements. Instead, owners are allowed to declare select measurements while the rating office assigns other parameters. Where input data is lacking, the rating office will apply estimates or default values that err to a faster rating.

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

    Some races have an APH 500 Rule. This states that all boats that have an ORC APH of 500 or lower must have a valid ORCi certificate to race. Please check your race's NOR to determine which level of certificate is needed for your boat. 

  • Partially Measured v. Fully Measured

    Partially Measured - owners are allowed to declare a subset of the complete measurement, while other parameters are assigned by the rating office. Where input data is lacking, the rating office will apply estimates from sister-ship data that err to a faster rating.

    Fully Measured - based on a complete measurement carried out by a US Sailing Official Yacht Measurer. This is the most accurate rating the rule system offers.

      Declared Crew Weight - The owner/PIC has the ability to declare a maximum crew weight for the boat.  

      Maximum and Minimum Crew Weight

      Maximum Crew Weight - This value is either a calculated default value, or declared by the owner/PIC (see above for more details). Under the ORC Rating Rules and ORR Rulebook, to race within compliance of your certificate a boat's maximum crew weight on board while racing must NOT exceed the maximum crew weight listed on the certificate. 

      Minimum Crew Weight (ORC Only) - This value is a calculated value based on the maximum crew weight listed on the certificate. The minimum crew weight is 80% of the maximum crew weight. In order to sail within compliance of your certificate a boat's crew weight while sailing must NOT be less than the minimum crew weight listed on the certificate.

    • ORR Gear Weight

    • Starting in 2025, all boats receiving an ORR Certificate will be rated with a default gear weight. If a boat chooses to carry emergency steering and/or life rafts, these items may be weighed and factored into the rating. 

      Should a boat choose to carry emergency steering or life rafts, and wants to have them measured, this MUST be completed by a US Sailing Recognized Measurer. The measurer will weigh the items and report the weights to US Sailing for incorporation into the ORR certificate. 

      If you have questions regarding ORR Gear Weight, please contact US Sailing at offshore@ussailing.org .
