Sounds like your area. Locally for me, ie puget sound, we have a freebee rag that is handed out at the local WM's, marina's etc, and you can get your regatta in the calender for free, and sometimes a write up. Along with there are online calenders with that yrs races on it. With 1-3 meetings in the late fall for the different clubs to get together, schedule so there is not an overlap of the BIGGER races.
I went around last fall with posters for my clubs BIG regatta, and not one club/store/marine type establishment turned me down if they had a buliten board to hang things like this.
Also, some clubs require that you own a boat to belong, others are time share styles, where they own the boats, you pay or as a member can use theboats.
She drives me boat,
