A Coconut Grove man narrowly escaped serious injury Monday night when he ran a high-performance boat deep into the mangroves, according to the Florida Fish and Wildlife Conservation Commission.

Daniel S. McBride, 39, apparently was returning from a day of fishing about 10 p.m., driving a 36-foot Concept powered by three 300-horsepower Mercury outboards. He reportedly missed a channel for South Sound Creek in John Pennekamp Coral Reef State Park.

Crossing Airport Flat, McBride hit the mangroves just south of South Sound Creek, crashing 250 feet into the trees before coming to a stop, said FWC spokesman Bobby Dube.

Alcohol was not believed to be a factor. McBride apparently had his GPS programmed incorrectly and his boat was not properly lit at the time, according to the FWC.

McBride reportedly was knocked unconscious and awoke when his dog began licking the cuts on his head and forehead. He didn't report the incident until the next day, when he called Sea Tow Key Largo for assistance, Dube said.

The FWC responded with a Department of Environmental Protection biologist. McBride refused medical treatment.

A full damage assessment will be conducted by DEP, Dube said.
