(FoxNews) - A boat whose owners advertise it as a "floating wine tasting room" started sinking near Alcatraz in San Francisco Bay, but all 22 people on board were rescued safely. U.S. Coast Guard Petty Officer Pamela Boehland said the 40-foot boat the Neptune hit an unknown object in the bay Friday night, leaving it with a 1-foot gash. Boehland says the boat began taking on water and sinking, but a Coast Guard boat happened to be nearby, taking on board most of the Neptune's passengers and summoning another Coast Guard boat that picked up the rest.
