One person died and several others remain missing after a three-deck pontoon pleasure boat caught fire and sank near Alcatraz Island on Tuesday [1, 2].
The incident highlights the dangers of onboard fires on multi-deck vessels, where rapid capsizing can trap passengers and complicate rescue efforts in open water.
The vessel was traveling in the San Francisco Bay off the coast of San Francisco, California, when a fire broke out [2, 3]. The flames caused the boat to capsize and sink into the bay [1, 2]. Emergency responders launched a search and rescue operation in the waters surrounding the historic island prison.
Officials said 16 people were rescued from the water [2, 8]. One fatality has been recorded [1, 2]. Reports regarding the number of missing persons vary between sources; some reports indicate two people are missing [3, 4], while others state three people remain unaccounted for [2, 5, 6, 7].
According to some reports, there were 19 people aboard the vessel in total [3]. The three-deck structure of the pontoon boat may have influenced how the vessel responded to the fire before it overturned.
Search teams continued to scour the area of the San Francisco Bay following the Tuesday afternoon disaster. The cause of the fire that led to the sinking has not yet been determined.

The discrepancy in missing person counts—ranging from two to three—suggests an ongoing effort to reconcile passenger manifests with the number of rescued survivors. The sinking of a multi-deck pontoon boat, which is typically designed for stability, indicates that the fire likely compromised the vessel's buoyancy or caused a rapid shift in weight, leading to a quick capsize.
