To add to sfgary you can also launch at Marina Bay Yacht Harbor in Richmond off of Interstate 580. Plenty of slips, free ice, nice facilities, sailing school and lots of Hunter sailboats on D dock and a few restaurants in walking distance. From there you can take day and overnight trips to Tiburon (recommend lunch at Sam’s overlooking SF), South Beach (south of the bay bridge with lots of restaurants), Sausalito, outside the Golden Gate bridge, Coyote Point (south of San Francisco), Alameda, Benicia, etc. If you do that stop by berth D43 in Richmond Bay Yacht Harbor Marina or berth 311/321 in the Benicia Marina for a beer. If you are around on Wednesday in Richmond during your trip you can join us on a Hunter 31 for a beer can race and $8 dinner afterwards with the Richmond Yacht Club.
Enjoy your trip.
