The Coast Guard says it rescued 26 people from a yacht that ran aground on rocks and took on water in San Francisco Bay.

No injuries were reported.

Authorities in San Mateo, Calif., say they received a distress call early Sunday from the 52-foot cabin cruiser Giant Feet.

The Coast Guard and fire crews launched a number of rescue boats, but those vessels could not reach the yacht because water in the area is too shallow.

Eventually a helicopter was used to deliver a life raft and a rescue swimmer.

Officials said all 26 people on the yacht were taken to a San Mateo County Fire Department post at the Coyote Point Marina.
