Here are the current US Sailing Portsmouth Yardstick numbers, which can be converted to a PHRF rating:
Catalina 22 (FK, No Spi) CAT22F 97.1 97.2 96.8 (96.0) [94.6]
Catalina 22 (SK/WK, N/Spi) CAT22 96.3 98.4 96.3 95.3 95.1
Catalina 22 (SK/WK, w/Spi) CAT222 94.7 (97.5) 95.3 94.5 (93.9)
We entered a PHRF race down the coast in 2014 and all 4 C-22's, which included 2-swing keel boats, a fixed keel boat, and my wing keel boat, all were given a PHRF rating of 288, no one was flying a spinnaker.
PHRF numbers can be adjusted locally also.
