A Riverbank woman suspected of driving under the influence crashed into a pontoon boat at Bob's Marine on Briggsmore Avenue.
The impact caused a chain reaction that damaged three other boats, according to Modesto police Sgt. Craig Breckenridge.
"The driver called 911 and said she didn't know her location but said she was surrounded by boats," Breckenridge said.
The crash early Sunday was at least the third in six years on that stretch of Briggsmore just east of Oakdale Road, where the speed limit is 50 mph and the road curves south.
Modesto police called Bob's Marine owner, Bill Donaleski, about 4 a.m.
"The phone rings, and I thought, 'Oh, man, not again,' " he said.
About an hour earlier, Lori Campbell, 43, was driving west on Briggsmore when she veered off the paved road and onto a dirt incline that borders a canal.
She then crashed through the chain-link fence that surrounds Bob's Marine and into the pontoon boat, which propelled it into the boat next to it, and so on, until four boats were damaged. The boats were there to be repaired.
As Campbell described her surroundings to dispatchers, they pinpointed her location using her cell phone signal.
She was taken to a hospital with mild to moderate injuries, Breckenridge said.
Because of her condition, she was cited, instead of arrested, for driving under the influence and given a notice to appear in court.
At the hospital, Campbell was given a breath test, which registered a blood-alcohol content of 0.16 percent, twice the legal limit, Breckenridge said.
In March 2008 two teenage passengers in a BMW were ejected when the driver lost control of the vehicle at 80 mph and crashed into several boats at Bob's Marine.
The two passengers who were ejected, a 17-year-old girl and a 19-year-old man, suffered major injuries.
The driver was charged with two counts of driving under the influence causing injury and was found guilty of one count, according to court records.
In July 2006 an Oakdale man died near the same bend in the road when he lost control of his motorcycle.
Michael Barnard, 27, was traveling 100 mph when he went off the road, and his body struck a pile of concrete in a small gully near the roadway.
Donaleski said there have been several other less serious accidents in front of his business and after each one he calls the city to request a guardrail be installed.
On Monday, several hundred feet of tire tracks could be seen in the dirt leading to the fence where Donaleski patched the hole with plywood.
While he was repairing the fence Sunday morning, he said he saw another near-accident in which the driver of a car drove onto the dirt shoulder, overcorrected and spun out in the middle of the street.
No one else was around, and the driver appeared unharmed, Donaleski said.
