Mary, how do you define 'racing sailor?'
I would hazard most of the Coast Cat club isn't 'racing' sailors, but folks who attend 1-3 regattas a year. The Ocean Springs Yacht Club is comprised at least 3/4 if not a larger percentage, of people who don't even own a boat or sail at all
Tami, I think a racing sailor is someone who participates in races. If most of your cat fleet's sailors participate in 1-3 races a year, I would call them racing sailors. Only caveat is I don't think the Round the Island Race (and a few other events of that type in other parts of the country) should count, because for lots of sailors it is more of a "happening," an adventure, a fun cruise; and people will do a once-a-year event like that even though they never "race" otherwise.
And yacht clubs don't count. Most of them have turned into social clubs, unfortunately.
