The attendees, all described as adults, most of whom were family members, were aboard the 50-foot, three-deck cabin cruiser based out of Stockton when it may have been struck by a wave in rough waters, authorities said.
The man who died was identified as Clifford Joseph Boisa, a 79-year-old Sutter County resident, a rep for the Office of the Chief Medical Examiner said Wednesday.
\u201cOur understanding was there was some kind of memorial service that they were engaging in. That\u2019s why they were using this particular vessel,\u201d San Francisco Fire Chief Dean Crispen <\/strong>told reporters Tuesday night.
When members of the San Francisco Police Marine Unit arrived, they found a man in the water who was in \u201csevere distress,\u201d Crispen said. He was taken onto the responders\u2019 boat and given CPR but was eventually declared dead.
A dog was also on board and is dead, he said.
When first responders arrived, some people were in the water, others were on the sinking boat and others were falling into the water, Crispen said.
Thirteen people were safely rescued and three more were taken to hospitals, where they were stabilized and were expected to be released Tuesday night, he said.
The three missing people were the focus of an intense search and rescue operation that will continue through the night, Coast Guard Lt. John Corvino said at the news conference. Searchers were going to scan the sea from the air and the surface, he said.
Firefighters are \u201cin full rescue mode,\u201d with 11 boats and divers as part of the response, Crispin said.
\u201cWe are going to continue for hours to make sure that we find these … missing people, if possible,\u201d he said.
The vessel launched from San Francisco\u2019s St. Francis Yacht Club, Crispen said.
Helicopter video from NBC Bay Area showed responding rescue boats and debris floating in the water. Video from the station appeared to show some of the rescued people with blankets on shore.
Local police departments and private vessels also responded, Crispen said.
San Francisco Mayor Daniel Lurie said, \u201cThis is an all-hands-on-deck search and hopefully rescue.\u201d
Crispen said that at this time of year, there are typically whitecaps in the water from wind, which is challenging. But, he said, regardless of the wind, \u201cwe\u2019re going to continue to search either way.\u201d
Alcatraz Island is the site of the famous prison around 1 mile offshore in San Francisco Bay. It was closed as a federal prison in 1963 and is now a national park.
Crispen said the search would be extensive.
\u201cOur standard operating procedure is to continue to search as long as it\u2019s safe enough for us to search,\u201d he said.
He said divers were in the water, helicopters were above, and officials were searching areas where survivors in the water would tend to move to.
\u201cThis search will go on for some time,\u201d he said.
