Boat Capsizes Near Alcatraz, Killing One and Leaving Three Missing

The U.S. Coast Guard is preparing a marine casualty investigation while crews continue searching for three people using thermal imaging and tide modeling.

Overview

  • The 50-foot, three-deck cabin cruiser Volare capsized roughly 600 yards off Alcatraz on Tuesday while carrying about 19–20 adults who were reportedly holding a memorial service.
  • Rescuers pulled 16–17 people from the water and took three to hospitals with non-life-threatening injuries while one rescued passenger later died and a dog on board also perished.
  • The man who died was identified by the San Francisco Office of the Chief Medical Examiner as Clifford Joseph Boisa, 79, of Sutter County.
  • An 11-vessel, air and dive search has continued into the night using thermal cameras and tide-prediction modeling to locate three people still unaccounted for.
  • Officials say there was no clear evidence of fire, witnesses reported rough seas and that the boat likely took on water or was struck by a wave, and authorities will investigate the cause once search-and-rescue operations allow.
