Born in America. Used in Antigua.

With just under two months remain until the beginning of the 2025 Classic Yacht Challenge Series, the Northeast USA’s quintessential classic yacht racing series is governed by CYOA’s unique rating system, the Classic Rating Formula (CRF). This scoring system is regularly updated and helps yacht owners get their vessels rated for racing without a great deal of hassle.

This year, CRF has gone beyond US boundaries and was adopted by the famed Antigua Classic Yacht Regatta as their main rating system. 2025 marked the 36th running of the regatta, which started as a toes-in-the-sand, laid back classic sailing event, and in many ways continues that tradition despite the event’s growth.

This is actually the second year that Antigua has used CRF. However, this year the rating system was used for all divisions and classes for the first time. “Lots of classic boats do just one regatta and they found that getting different ratings was expensive for them. But CRF is inexpensive and is not as hard to get measurements as some other rating systems,” said Robin Stout, coordinator for the Antigua Classic Yacht Regatta. – Full report
