Q. I understand that a ‘tweener’ sail whose luff is not attached to a stay (termed a ‘headsail set flying’, or HSF) that is kept in place throughout an event is not allowed under CRF 2024.  Since these sails are becoming more user-friendly and popular for both racing and cruising, will CRF be changed to account for a HSF in the future?

A. Yes, it is likely that ‘headsails set flying’ (HSF) will be addressed by CRF in the future. Discussions on
how best to do this are now underway. One option under consideration is for the rated sail area for a
boat that declares a HSF will be increased by a modest multiplier, in the same way that CRF accounts for
differences in standing rigging type.
