Welcome to CF and to sailing; the Bay is one of the greatest and most challenging places to sail, and a great place to learn. You will never be without a challenge. If you get tired of the
fog,
head into Richardsons Bay or north up to
China Camp or Paradise Bay; or tuck into Ayala Cove at Angel Island.
Learn the tides and currents (Kame Richards, Pineapple
Sails, offers inexpensive short courses on currents inside and outside the Gate), read religiously Latitude 38. and above all enjoy. You can almost probably hitch a ride as rail meat during
beer can races; a great way to learn even if you're not into racing that much; South Beach YC has theirs on Fridays; folkboats and others
race often Wednesday evenings out of SF Marina's clubs; and the Bay View Boat Club has Monday Nite Madness (every other week, I think). Just bring foulies, a little
beer, and enthusiasm.
You will find a great bunch of people sailing here, and a great many places to explore.
