RIO VISTA -- Three friends had a close call in the chilly waters of the Sacramento-San Joaquin Delta early Tuesday when a short boat trip home ended up with an overnight search for two of them after their small dingy capsized, according to the Rio Vista Coast Guard.

Two women were reported missing around 2 a.m. Tuesday by their male companion who had battled the strong currents and swam ashore east of the the Happy Harbor Marina, near Oakley and Rio Vista, according to Coast Guard Petty Officer Josh Martin.

Both women were recovered cold, but alive, after spending several hours in the Delta waters, the Coast Guard. One of the women was found at 8:47 a.m., clung to tule reeds and was been transported to hospital in Antioch, said Rio Vista Coast Guard officer Justin Varvel.

The second woman, Andrea Anderson, was found by a passing motorist just south of Bradford Island after she swam ashore. It was the same area one of her male boating companion was found about 2 a.m.

Officers at the Rio Vista Coast Guard Station were alerted to the accident when a woman living near the stretch of water where the 8-to-10-foot dinghy capsized heard calls for help from the male passenger, who had managed to get ashore in the remote area where the boat went under, said Martin.

The three friends had borrowed the boat to travel less than one mile to where there car was parked near the marina after visiting a friend's houseboat in the Delta, said Martin.

Anderson said trouble began when the dingy engine died.

"The battery died in the motor," she said. "We tried oaring (rowing), but the current was too strong and it kept taking us further and further out...The waves were getting bigger and they started tipping us over....The boat just started going down."

Anderson swam for the tule lillies that covered a nearby inlet.

"I was in the water for 45 minutes until I hit the tules and then I was able to pull myself up on land and made a bed of tules," she said. "I lay there until I heard the helicopter."

Anderson stood in a blanket on the dock. Meanwhile, her male companion was transported to Lodi Memorial Hospital because "he was fairly hypothermic and had shortness of breath," according to Martin.
