It's been decades, but Cal Sailing Club got me started. It's cheap and I found the instruction to be good, mostly University of California students. I don't know if they still have them, but there were a few keelboats that could be taken into the Bay. Their main boats for instruction were centerboard. Be prepared to get wet though and have proper gear for that. Cal Sailing is located in the Berkeley Marina, turn left at the stop sign then curve around to the right and then look for the second building on the left beyond the parking lot if they still have the same location. If not, ask at the harbor master’s office across the street on the right.
If you want to spend the money on ASA courses, I hear these folks are good: Modern Sailing School & Club - San Francisco Bay Sailing Lessons, Charters and Rentals, Adventure Sailing
