For July 15 - 16, any keelboat with a valid PHRF certificate that does not have a one-design class in which to participate, may enter and race with the PHRF Fleet.  PHRF ratings from regions other than NCPHRF will be converted to NCPHRF ratings.  For invited classes who fail to meet the 5 boat class start minimum, FYC has the option to assign a Northern California PHRF rating to these classes and put them in an Open Class or PHRF A or B.
