CRF Rating

Welcome to the 2017 Classic Rating Formula website, and the CRFMkII, an updated rating system using all of the former CRF owner-declared data, plus three additional performance variables measuring beam, draft, and an additional spinnaker factor. The goal of the CRFMkII is to provide a more objective and transparent rating system.

The former CRF ratings accurately reflected the real world performance potential of some yachts within classes of similar sizes and types, and without CRF, we could not enjoy the classic yacht racing enjoyed by so many. Special thanks must go to the efforts of Chris Wick and others (Bill Doyle, Steve White, Maynard Bray, Joel White) who have created, maintained, administered the rating for decades. But, over time even with adjustments to the CRF, some yachts could not be rated fairly, plus there were concerns about transparency and fundamental flaws in the CRF. Using both the CRF and the essentials of the International Offshore Rule (IOR) (which rated a variety of boat sizes and types quite well until it was overwhelmed by optimization and exploitation) The new reformulation in CRFMkII improves the shortcomings of the former CRF.

For 2017, all yachts competing in a classic regatta will need a new rating. Applications for a 2017 certificate are available now. Just click on the GET/RENEW a CRF tab, and follow the instructions to set up your new CRFMkII account (you'll need to set up a new user account and password), and then start your application for a rating certificate. Any contact you need to make in reference to your rating continues to be managed through In addition, behind the scenes, to ensure accurate ratings, Chris Wick oversees the issuance of all certificates. With the new on-line format easier, faster processing and accessibility to the CRF database is also available for competitors.
