I am bringing my wife back to San Francisco for her surprise 40th birthday. Several friends from our time in the City are flying in and I would like to find something fun. I have chartered a sail boat for the day that docks at the marina next door to Pac Bell and would like something that can handle a party of 14, walking distance from the boat, and not to formal as we will all be in casual sailing clothes. This area has built up since we left and I just do not know what is available. Please help.
