We have been very successful in the Round the Island Race recently using a particular PY but....
One design, manufacturers' and development classes have rules on rig measurement.
By moving from the original rig design, we are in danger of being out of class for racing.
We may not have black bands on our masts and booms but when we go to race, race
committees will expect us to conform with the the designer / manufacturer's specifications.
Pedant moi?

David
PS I don't race with my gennacker
