Naufragio di una barca con 19 turisti, una persona è morta, due sono scomparse (VIDEO)

A recreational boat carrying 19 tourists sank near the historic Alcatraz Island in San Francisco Bay, resulting in one death and two missing persons. The incident occurred shortly after 3:30 p.m., when emergency services were called following reports of a vessel drifting approximately 500 meters offshore. Rescuers quickly arrived on scene, with police patrol units responding first before a large-scale search and rescue operation was launched involving eleven vessels under the U.S. Coast Guard’s jurisdiction. The boat, a pontoon-style craft designed for leisure activities, had been operating in calm waters near the island, which today serves as a popular tourist attraction managed by the National Park Service. According to initial reports, the vessel was nearly fully submerged, with only its roof visible above water, while fuel continued to spill from its still-operational engine. Moments later, the boat completely capsized, leaving rescuers scrambling to recover survivors. Of the 19 onboard, 13 were safely brought ashore by emergency personnel. Three others were taken to hospital, one of whom died despite resuscitation efforts due to severe injuries. Two individuals remain unaccounted for, and ongoing searches continue. Alcatraz Island, once infamous for its formidable prison system, has transformed into a major historical site. The former federal penitentiary, operational from 1934 to 1963, was known for its extreme difficulty in escaping, largely due to powerful ocean currents and frigid waters surrounding the rocky islet. Today, visitors can explore the island's preserved cells and exhibits, though the area remains subject to strong tides and weather conditions, particularly during winter months. The type of vessel involved in the incident, a pontoon boat, features a flat bottom supported by two or three long aluminum tubes, providing stability in calm conditions. These boats are often used for family outings or group excursions, offering wide seating areas and railings for safety. However, they are ill-suited for open seas or strong currents, making them inherently risky in such environments. Their design allows for comfort and space in sheltered waters, but their light construction and shallow draft render them unstable in rougher conditions. Emergency crews from the San Francisco Fire Department have joined the search effort, combing through the area after the boat overturned. Video footage captured by local television stations initially showed the vessel almost entirely underwater, with only its roof barely visible. As the situation unfolded, the boat fully submerged, raising concerns over the exact cause of the accident. Authorities have not yet released a definitive explanation, though early assessments suggest the vessel may have lost stability due to environmental factors. Rescue operations have focused on locating the two missing individuals, with divers and maritime teams working in coordination with coast guard assets. Weather conditions in the bay remained relatively stable at the time of the incident, though strong winds and waves could have contributed to the vessel’s instability. Local officials have urged caution regarding the use of such boats in more exposed waters, emphasizing the importance of adhering to safety guidelines and avoiding operation in adverse conditions.
