Classic Rating Formula
The goal of the Classic Rating Formula (CRF) is to provide an objective, accurate and transparent rating system that is uniquely suited to scoring classic yacht races. CYOA’s CRF Technical Committee routinely refines the formulae and factors used to calculate ratings annually, based on careful quantitative analysis of race results after each season. Maintaining the competitive balance within groups is a priority, but the ratings for most yachts will often change slightly from one year to the next even if the declared input data remains the same.
Each year, each vessel needs a new CRF Certificate ($50 per certificate with a $25 rush charge after June 1). Certificates only cover a portion of our operating costs and we rely heavily on volunteers. We encourage owners to also support the CYOA’s efforts with a $100 membership each year.
