This subject has been raised repeatedly and discussed at length by Central Council and they maintain the following:
One Design Handicaps are made available to racers who wish to race their boat under their "Class One Design" configuration, which does not include a non-flying sails configuration.
PHRF-LO sets the One Design Handicap to include all known penalties or credits either for sail sizes or configuration that may be included in the Class One Design Rule.
Eg:
J 24 ODR
Spinnaker Max Girth penalty of -3 included in handicap of 165
J 24
Spinnaker Max Girth penalty of -3 incurred. For an Adjusted SP of 165 (SP = 168)
Non-flying sails handicap = 183
If you have an ODR boat but would like a NFS handicap, you should apply for the (PHRF) class handicap as designated by the (no ODR) extension in the name.
Thanks,
