California Highway Patrol officers alerted the Coast Guard in San Francisco that three people were sitting on the hull of the capsized fishing boat and a rescue boat was dispatched, officials said.

A crew from the Coast Guard’s Bodega Bay station arrived about 30 minutes after receiving the alert and retrieved the three fishermen. They were not injured but had to be treated for hypothermia symptoms, the Coast Guard said.
