A. First, while it is possible that an input error has been made, be aware that the formulae and factors used to calculate ratings are routinely refined each year, so ratings often change from one year to the next. For example, beginning in 2020, a Standing Rigging factor effected ratings compared to 2019, as did an improved Stability Correction. Similarly, beginning in 2020 ratings reflect an adjustment to the effective sailing length of canoe stern (double ended) hulls.
Of course, it is possible that an error in data input has been made. If you feel that this is the case, file an inquiry. On receipt of your inquiry, the CRF Technical Committee will review the data to see if there is an error. If so they will notify you, correct the rating, and issue you a new certificate.
