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, for 2020, a Standing Rigging factor will effect ratings compared to 2019, as will an improved Stability Correction.
Also 2020 ratings reflect an adjustment to the effective sailing length of canoe stern (double ended) hulls. Of course, it is also possible that an error in data input has been made. If you feel that this is the case, file an inquiry. The CRF Tech Committee will review if there is an error. If so they will notify you, correct the rating, and reissue you a new certificate.
