ORC Multihull Certificate
  ORC Multihull certificates come in four A4 pages. The first page gives a general overview of the boat with its rated boat speeds, in addition to the measurements of the main hull, the propeller, the rigging and the sail.

The second page is presenting the scoring options.
    Page 1 Page 2 Page 3 Page 4
 
The third page is showing a detailed list of measurements of the hull and appendages, propeller, rig, flotation, and the measurement inventory, while the fourth page is reserved for measurements within the sails inventory. 

Place the cursor over different parts of the certificate page for a brief explanation. More details are given in the measurement and scoring sections, while complete definitions can be found in the appropriate rules documents.

RATING OFFICE

This is a space for the Rating Office logo. ORC Rating Offices are established worldwide in each country that has active offshore racing. Rating offices have several functions, including supervising the measurement and rating of yachts, supporting ORC racing by administering to their national fleets, and issuing ORC certificates.

Currently, ORC Multihull certificates are issued by the ORC Central Rating Office while this role will be given to the National Rating offices in the future.

SAILS INVENTORY

This is the list of all the measured sails recorded for determining a boat's predicted speeds and ratings, and includes at a minimum the largest of each sail type in the inventory. Each sail's measurements, area, measurement date, name of measurer, manufacturer and material are shown for each of the following sail types: Mainsail, Headsails (set on the forestay and set flying), Symmetric spinnaker, Asymmetric spinnaker, and Mizzen and Mizzen staysail.

Any Headsail set flying and any Asymmetric spinnaker between 75-85% SHW/SFL are required to be recorded in the sails inventory.

CERTIFICATE

ORC Reference number is a unique number identifying that certificate and may be retrieved in the ORC database available at the ORC Sailor Services.

There is an issue date as well as a VPP version used together with the latest date for the validity of the certificate.  

A boat shall have only one valid certificate at any one time. The valid certificate is the last one issued.

ORC Certificates are valid for one year. This is because the VPP software calculations are updated yearly based on the ITC’s latest research of aero and hydrodynamics, as well as improvements made from analysis of race results and boat performance during the racing season, and submissions made from ORC Nominating Bodies.
