I live in Irvine, CA. I retired from sailing and am now windsurfing all over the area.
I know hobiegary on the forums has a group of cat sailors in Marina Del Rey. I have seen cats at Sunset beach in long beach. I have also seen cats at cabrillo beach and i have seen more at my favorite Lake Isabella (f'n windy).
Message hobiegary he has helped me many times over the years and is a nice guy.
