The Alcatraz Crossing (to Aquatic Park, Saint Francis Beach or Crissy Field) is a beautiful swim! Breathe on your starboard side and see the Golden Gate Bridge in early morning sunlight, perhaps with fog
tendrils tickling the towers. Breath to port and see the city skyline against the morning sun.
The coast guard prefers that we complete the swim before the ferries start running so most crossings are morning swims.
I do this swim several times a year and will continue to do so. I also swim along the coast. This video does not deter me. Doubtful it will deter most. Sharks are always present whether we see them or not. They are intelligent and curious and rarely nibble on humans. One is more at risk of being run over by a boat than bitten by a shark.
The map of Bay Area shark attacks that StuM has posted shows that most attacks have occurred concurrently with fishing
canning activity. There are thousands of people swimming, surfing, diving
, kiteboarding etc in this area on any given day without shark encounters.
The video shows a shark hunting and eating its natural food
of seal or sea lion. That is no reason to stop swimming the bay or the coast.
