RedactedNarrative: At apx. 4:20p.m. this date, three personal water crafts were traveling up river from Cropwell when one of the craft began experiencing mechanical trouble. Vessel 1 and Vessel 2 both slowed down to check on this third vessel. Vessel 2 did not react in time to Vessel 1 coming off of planing speed and was following closely behind and within the wake of Vessel 1. Vessel 2 struck the back of the passenger on Vessel 1, knocking her in to the water. This was a glancing blow as Vessel 2 was already attempting to turn toward the port side. The passenger and operator of Vessel 2 entered the water to support the victim who was complaining of pain in her back. 911 was called by the passenger on the 3rd craft. When R/O arrived, the 3 crafts were floating in the area in front of Pirate's Island and 3 subjects were in the water, each wearing a PFD. After assisting in securing the injured party next to the patrol boat, rescue was contacted to bring a backboard in order to safely remove her from the water. Passing vessels were asked to reduce speed to an idle. At apx. 5:15p.m. the victim was picked up and transported to shore to a waiting ambulance. She was then transferred to St. Vincent's Hospital Birmingham. There was no visible nor reported damage to either craft involved in the collision. Once information was gathered, the crafts were released on the scene.
