Q. Why is standing rigging material required in the CRF application?

A. The rigs of some older boats have been upgraded by replacing the original wire standing rigging with stainless steel rod, which implies a rating advantage.  Also, some boats are fitted with composite (typically carbon) standing rigging, that results in a substantial performance advantage. A Standing Rigging Factor that was new for CRF 2020 addresses this advantage via a rating adjustment.
