Sunday was also the second day of the 4th annual Brews on the Bay, sponsored by the San Francisco Brewers Guild. Each year it’s been held on the SS Jeremiah O’Brien, a World War II era Liberty Ship docked at Pier 45 at Fisherman’s Wharf.

Normally the ship is a tourist attraction, but some of the volunteers really got into the beer festival.

Almost all of the beer was being poured on the Bay side of the ship, affording festival-goers with some great views.

The ship was filled to capacity.
