ORC rating system gets updates for 2025
Published on November 5th, 2024
Singapore (November 5, 2024) – Representatives of boat owners and sailors from the 41 nations around the world that use rating certificates from the Offshore Racing Congress (ORC) met today at the 55th edition of their annual Congress meeting.
At this meeting a variety of important issues have been discussed and ratified that relate to the structure of the organization, its growth and development around the world, its financial health and budget plans for the future, reports from ORC’s Committees and approval of their recommendations for rule changes and policies for the coming year.
Following positive trends seen in the last several years, 2024 was a good year for ORC with modest growth in both the numbers of boats and certificates issued in numerous countries around the world. From October 31, 2023 to the same date in 2024, there were 14,328 ORC certificates issued, a 0.3% increase, and the number of boats receiving these certificates increased to 9,221 boats, a 3.5% increase.
Detailed information on ORC in 2024 is found in the Annual Report: https://orc.org/sailors/news-archive/annual-report-2024.
Besides providing ORC International, ORC Club, ORC Double Handed, and ORC Non-Spinnaker certificates for Monohulls, Multihulls, Sportboats, and Superyachts, ORC this year also worked with the J Class to provide special ORCj certificates and ratings.
To assist with technical matters such as measurement, ratings, and scoring, ORC technical staff provides on-site support at ORC World and European events, as well as many regattas for the Superyachts, Multihulls, and J Class yachts.
A report from the International Technical Committee (ITC) by chairman Andy Claughton showed the ongoing improvement to the Velocity Prediction Program (VPP) based on user inputs on specific topics such as Headsail furlers, Non-manual power systems, expansion of the VPP to include four knots, effects of appendage surface areas, and the committee’s ongoing basic research on items such as improvement of downwind aero coefficients.
In total, the anticipated effects of VPP changes for 2025 on the 1800 designs in the ORC test is is a modest 0.4% decrease of the GPH ratings. A more complete summary of this work is available at https://orc.org/sailors/news-archive/orc-int-technical-committee-report-2024.
Claughton also reported on the status of the Weather Routing Scoring initiative approved last year and developed and tested throughout 2024. Fifty races were both officially and unofficially scored for race organizers and the software improved in cooperation with PredictWind.
Early in 2025, a web app is anticipated to become available for broader access to race organizers beyond just the ORC championship events. Guidelines will be developed on how to use this new method to bring fair ratings to offshore races of six hour to four day duration, with the latter possibly being extended to longer durations as more testing is made in 2025.
“This is an exciting development for ORC,” said ORC Chairman Bruno Finzi. “Making this available as a web-based tool in cooperation with our partners at PredictWind opens up the possibility for its use in routing for all sailing boats, not just for getting ratings for a fleet of racing boats. We congratulate the hard work this team has put in this year for development of WRS.”
Another application of the ORC VPP is a class being developed called ORC Classics that may breathe new life into otherwise old and forgotten designs. Deputy Chief Measurer Nicola Sironi describes the vision for forming this “new” group:
“We would encourage Race Organizers to establish an “IOR” Division within their existing ORC fleets that is dedicated to boats with an Age date between 1970 and 1990, the IOR era,” explained Sironi.
“Many of these boats are still in commission, have a measured hull file, and are suitable for offshore races, but just a few of them keep actively racing, often getting rather poor results. A separate Class or Division dedicated to them will be an encouragement for them to keep racing, and motivate others to join races.
“The only requirement to belong to this group is the Age date – there is no need for any additional measurements or certification beyond what is required to obtain an ORCi or ORC Club certificate, so this is ready for immediate implementation. Boats older than the IOR era can also be included, when they have measured data available, and they comply with the category of any relevant safety rules for any given race.”
