A three-deck, 50-foot cabin cruiser chartered by a family to hold a memorial service for a loved one capsized and sank Tuesday afternoon in the cold, current-swept waters of San Francisco Bay roughly 600 yards from Alcatraz Island, killing one person and leaving three others missing as a massive overnight search operation combed the bay’s treacherous tidal corridors.
One person and a dog are dead, and three people remain missing after the three-deck cabin cruiser, identified as the Volare, carrying 20 people, sank in the rough, frigid waters. The passengers, believed to be mostly family members visiting from outside the Bay Area, had chartered the vessel to hold a memorial service for a loved one.
San Francisco Fire Chief Dean Crispen said emergency crews arriving at the scene near Alcatraz found the vessel almost entirely submerged, its motor still running and leaking fuel into the water around it. One man pulled from the water was in severe distress, received CPR on the dock after being brought ashore, and was later pronounced dead. Three others were transported to area hospitals in stable condition and were expected to be released Tuesday night, while 13 survivors were brought safely to shore at Gashouse Cove Marina near the Fort Mason Centre. A dog aboard the vessel also died.

A Memorial That Became a Rescue Scene
The attendees, all described as adults, most of whom were family members, were aboard the 50-foot, three-deck cabin cruiser when it may have been struck by a wave in rough waters, authorities said. “Our understanding was there was some kind of memorial service that they were engaging in. That’s why they were using this particular vessel,” San Francisco Fire Chief Dean Crispen said at a news conference Tuesday night.
The vessel was reported to have launched near the St. Francis Yacht Club in San Francisco, though a person who answered the phone there said the club had no immediate information on what happened. The emergency call came in just after 3:30 p.m., initially reported as a vessel fire, though Crispen later said there was no evidence of a fire and no burn injuries were reported among any of the survivors. First responders arrived to find the vessel mostly submerged, with the motor still running and leaking fuel.
Among those who responded to the scene before official rescue crews arrived was the captain of the Bass-Tub, a nearby private vessel that happened to be in the area. By the time the Bass-Tub reached the stricken boat, the flames reported in initial calls were out, but the pontoon was sinking. Some people were already in the water while others remained aboard. The captain tried to hand out life jackets to the passengers. One woman’s head was injured. “We figured we would get her first,” the captain said. A deckhand lowered a swim ladder and threw a life ring into the water to help pull her aboard. “It was scary,” the captain said. “I don’t want to see anybody in that situation.”
‘Full Rescue Mode’ as Night Fell Over the Bay
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 the San Francisco Fire Department deployed an extraordinary assembly of resources to the scene, 11 boats, divers, jet skis, helicopters and several private boaters who joined the effort voluntarily. “Right now we are in full rescue mode,” Crispen said. “We are going to continue for hours to make sure that we find these missing people, if possible.”
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.
San Francisco Mayor Daniel Lurie called the sprawling, multi-agency response an “all-hands-on-deck search and hopefully rescue,” describing the scale of the operation as among the largest maritime emergencies the city had responded to in recent memory. The American Red Cross deployed disaster mental health and spiritual care teams to the scene to support survivors and family members, providing dry clothing, food, blankets and comfort kits to those brought ashore.
Waters That Punish the Unwary
The waters surrounding Alcatraz Island, once a federal penitentiary whose reputation for inescapability was built on the same forces now working against rescue crews, present a uniquely unforgiving environment for anyone who enters them unexpectedly. Water temperatures in San Francisco Bay near Alcatraz average between 50 and 55 degrees Fahrenheit year-round, cold enough to impair an adult swimmer’s coordination and strength within minutes and to cause life-threatening hypothermia in under half an hour. Tidal currents in the channel between Alcatraz and the city’s northern waterfront can run at three to four knots, carrying a person in the water rapidly away from the scene of a capsizing even on a calm day.
Tuesday’s conditions added further hazard. The 50-foot cabin cruiser may have been struck by a wave in rough waters, suggesting the sea state at the time of the capsizing was not benign, and the speed with which the vessel went under — arriving at the scene already nearly fully submerged — pointed to a rapid and catastrophic loss of buoyancy that gave passengers little time to prepare or don life jackets before entering the water.
Boating experts are questioning what caused a three-level, 50-foot cabin cruiser carrying 20 people to sink near Alcatraz as first responders continue their search and rescue efforts. The US Coast Guard is expected to open a formal marine casualty investigation once the search operation concludes.
Investigation Underway, Answers Still Scarce
Authorities said they expected to provide additional details Wednesday morning as the search mission continued into the night. Crispen said the search would be extensive. “Our standard operating procedure is to continue to search as long as it’s safe enough for us to search,” he said. “This search will go on for some time.”
The Volare’s registry and operator have not been publicly identified, and questions about the vessel’s maintenance history, safety equipment and the circumstances of the capsizing remained unanswered as of Tuesday night. For the family members who had boarded the vessel that afternoon to scatter ashes or otherwise honor someone they had lost, the memorial had itself become a catastrophe requiring mourning of its own.
