BEFORE TOURISM
A working shore
The bay was navigable as far south as San Jose until the 1850s, when hydraulic mining released massive amounts of sediment from the rivers that settled in those parts of the bay that had little or no current.

1927
Sailing becomes organised
Founded in 1927, the Saint Francis Yacht Club (StFYC) was formed when some of the members of the San Francisco Yacht Club decided to move their clubhouse from Sausalito to Belvedere, California to escape the rapidly growing commercial activity of Sausalito.

TODAY
San Francisco Bay now
San Francisco Bay is popular for sailors (boats, as well as windsurfing and kitesurfing), due to consistent strong westerly/northwesterly thermally-generated winds – Beaufort force 6 (15–25 knots; 17–29 mph; 8–13 m/s) is common on summer afternoons – and protection from large open ocean swells.
