RedactedNarrative: There is a very narrow channel just off Shelby Shores. This channel is between the bank and a submerged stump field. Witnesses advised the operator had the boat on plain in stump field just off the bank. While yelling at the operator trying to get him to slow down and come closer to the bank but he continued on. The operator stated that he turned to go out in the channel. The boat hit a stump and the victim fell forward hitting her face on the forward deck. She was holding and landed on top of her 11 month old baby boy. The baby did not have any visible signs of injury but was transported to Children's Hospital in Birmingham. The female victim had facial trauma and was flown to UAB Trauma Center in Birmingham. I was told she had several teeth missing and I found one still in the boat. The operator advised the boat was taking on water so a home owner let him put it on their boat lift so it would not sink. The vessel had not been registered since 2008 and it does not have a HIN assigned to it.
