The "Corinthian Race" was named for the yacht club. Peter Hogg was a member (Commodore) at the CYC back then. And, yes, there have been several times when the race was moved to the GGYC. Yacht Club management changes. Does the SSS have a list of CYC members who race in SSS races, especially the Corinthian? Club members are usually the folks who can put some pressure where it's needed.
It's fair to remind everyone that the GGYC has been unavailable several times over the years, too. Matter of fact in the 1980s the SSS bought a membership in the GGYC for an SSS sailor so there would be a "say" in things.
