One person died and three others are missing after a boat carrying 20 people capsized near Alcatraz Island on Tuesday [1, 2].

The incident highlights the dangers of rough sea conditions in the San Francisco Bay, where rapid weather changes can jeopardize pleasure craft.

The vessel, a 49-foot cabin cruiser named Volare, overturned and sank around 3:30 p.m. on July 14, 2026 [3, 4]. Authorities said the boat began to take on water due to rough seas before capsizing [5, 6].

Emergency responders rescued between 16 and 17 people from the water [1, 4]. San Francisco Fire Department officials said one person died and three remained unaccounted for following the accident [1].

Witnesses said they saw the vessel struggle in the choppy waters before it turned over [5]. The U.S. Coast Guard said it would search for the missing three boaters throughout the night [6].

Search and rescue teams focused their efforts off the coast of Alcatraz Island, utilizing local maritime resources to scan the area [2, 6]. The total number of people aboard the Volare was 20 [4].

This tragedy underscores the inherent risks of navigating the San Francisco Bay, where strong currents and unpredictable swells can quickly overwhelm even mid-sized vessels like the 49-foot Volare. The discrepancy in reported rescue numbers and vessel types in early reports reflects the chaos typical of active maritime search-and-rescue operations.
