THE MEMORIAL TRAGEDY: A cruise meant to scatter a ...

The purpose behind the ill-fated voyage of the Volare makes the disaster exponentially more heartbreaking. A group of 20 family members and friends from the Stockton and Sacramento areas had boarded the vessel specifically to scatter the ashes of Maria Boisa, a Fremont nurse who tragically died 10 years ago at age 32. What was supposed to be a final act of closure and love transformed within minutes into a fresh, multi-generational family nightmare. The memorial trip instead claimed the lives of 79-year-old retired reserve deputy Clifford Joseph Boisa and 58-year-old Tondra Miller, leaving a family devastated and investigators parsing through a catastrophic sequence of events on the water.

The Sinking of the Volare

The tragedy unfolded on the afternoon of Tuesday, July 14, 2026, when a close-knit group of 20 extended family members and close friends boarded the Volare, a 49-foot, three-deck cabin cruiser registered out of Stockton. The excursion was meant to be a deeply solemn and meaningful family heritage gathering, organized explicitly to honor the late Maria Boisa a decade after her passing. According to automatic tracking data from VesselFinder, the pleasure craft cleared a San Francisco marina, passed under the Golden Gate Bridge twice, and visited Angel Island State Park before navigating its return loop across the central bay channel.

At approximately 3:37 p.m., the atmospheric and maritime conditions shifted violently. Though the National Weather Service had not issued a formal small craft advisory, local weather log arrays at Fort Point clocked sustained winds whipping between 20 to 22 mph, with sudden localized gusts peaking up to 30 mph. The incoming tides pulled in the exact opposite direction of the wind, generating massive, volatile five-foot swells that pounded the hull. Without warning, a massive wave crashed over the side of the Volare, instantly compromising its architectural stability. The vessel listed heavily to one side and rapidly rolled over onto its starboard side near Alcatraz Island, throwing many passengers into the freezing, fast-moving currents while trapping others below deck as the cruiser quickly downflooded and sank.

The Dramatic Broad-Daylight Rescue

Onlookers along the shoreline initially observed columns of steam rising from the water, which led to early, frantic reports to dispatchers that the vessel was on fire. The San Francisco Police Department Marine Unit and San Francisco Fire Department emergency assets deployed to the coordinate path immediately, but the first critical lines of defense were local civilian boaters. Two local fishermen, Justin Marceline and Michael Montoya, immediately abandoned their halibut trip and steered their small craft directly into the debris field, joining forces with the Bass-Tub, a 56-foot commercial sportfishing charter boat that hurried over from Fort Mason.

Good Samaritans and first responders encountered a scene of absolute chaos:

• Water Extraction: Rescuers executed high-velocity maneuvers to yank freezing victims from the bay, where some clung desperately to floating debris and a windsurfer’s board, while others bobbed without life jackets.

• Trapped Passengers: Through the windows of the rapidly submerged cabin cruiser, civilian boaters could see horrified family members pounding frantically on the glass as the vessel slipped beneath the surface.

• Medical Triage: A total of 16 survivors—including the boat’s captain and co-owner, 62-year-old John Boisa—were successfully pulled from the water and transported to a makeshift triage center at a Fort Mason warehouse. Three survivors sustained severe leg and head injuries from the water impact, requiring immediate ambulance transport to regional hospitals.

Despite the heroic intervention of civilian elements, the disaster claimed its first confirmed fatality on Tuesday afternoon. Clifford Joseph Boisa, a resident of rural Sutter County and the older brother of the captain, was pulled from the water in severe physical distress. First responders executed continuous CPR protocols as they rushed him to Gashouse Cove, but the elderly veteran was tragically pronounced dead at the dock, and his beloved family dog also perished in the capsizing.

Recovery of Tondra Miller and the Ongoing Search

Following the suspension of the U.S. Coast Guard’s massive 29-hour active search grid, which scoured over 950 square nautical miles, local police recovery units took exclusive control of the operation. On Thursday, July 16, 2026, at approximately 1:02 p.m., the SFPD Marine Unit was conducting systematic sonar scanning of the bay floor when a passing civilian vessel suddenly alerted officers to a body floating in the water west of Treasure Island, near the midpoint of the San Francisco-Oakland Bay Bridge. Officers immediately recovered the body, and the Office of the Chief Medical Examiner formally confirmed the identity as 58-year-old Tondra Miller (also known as Tondra Madruga).

Miller, a close family friend of the Boisa family who traveled from Sacramento County to take part in the memorial scattering of ashes, is the second confirmed fatality of the maritime disaster. Her sudden recovery has left two passengers still officially unaccounted for in the freezing bay: Carol Boisa (74), the sister of the captain, and Jackie Boisa, the wife of the late Clifford Boisa. Coast Guard Captain Jared S. Toczko and police administrators fear that the remaining missing individuals may have been completely trapped inside the enclosed main or lower cabins when the vessel inverted and sank.

Statistical and Logistical Matrix of the Volare Disaster

A Family’s Grateful Farewell and Technical Probe

Following the medical examiner’s formal notification, Quin Madruga issued a moving statement on behalf of the grieving family, breaking their agonizing silence to honor the late mother. The statement prioritized gratitude for the overwhelming wave of community support and the selflessness displayed by complete strangers in the middle of a catastrophic crisis.

“We extend our heartfelt thanks to the U.S. Coast Guard, the San Francisco Fire Department, the San Francisco Police Department, all of the first responders, and the civilian boaters and community members who selflessly assisted in the search and rescue efforts,” Madruga shared publicly.

The parallel technical investigation into the ultimate cause of the capsizing continues to intensify. SFPD Marine Unit divers and specialized salvage commands, coordinated by Police Commander Brien Hoo, have successfully used high-resolution sonar profiles to pinpoint the resting place of the Volare. The three-deck cabin cruiser currently rests completely submerged on a rocky, dark seabed at least 120 to 130 feet below sea level within a deep commercial shipping channel routinely traversed by heavy container ships heading to the Port of Oakland.

Because the extreme depth and strong, treacherous currents make it highly dangerous for standard local fire divers to attempt a direct internal search, authorities are preparing to deploy advanced underwater drones and remote-operated vehicles (ROVs) to explore the hull. These specialized tools will capture interior visual sweeps to determine if the remaining missing passengers are trapped inside, before federal investigators decide if a massive structural salvage operation to raise the sunken ship is legally and logistically feasible.
