RedactedNarrative: On 07/26/14 at approximately 1935, Vessel 1 was leaving President''s Bay in Apple Canyon Lake to tow a tube. Vessel 1 was previously anchored in Presidents Bay and had two anchors out. One anchor was tied off the stern and the other was tied to the starboard side of the bow. When Vessel 1 left the Bay, only the stern anchor was pulled from the water. Vessel 1 traveled at a No Wake speed until it reached the main lake. When vessel 1 reached the main lake, one of the boat occupants exited the vessel and got on to a tube attached to Vessel 1. As Vessel 1 accelerated to pull the occupant on the tube, the bow anchor raised to the surface of the water. As this occurred, the anchor left the water and returned to front starboard portion of Vessel 1 and struck an occupant in the face and head. After striking Victim, the anchor fell back to the water and snapped from the rope. Victim was knocked unconscious briefly and suffered lacerations to the upper lip area and a severe laceration to the top of the head. The operator of Vessel 1 immediately called 911. The occupants of the boat provided first aid to Victim and traveled back to the Apple Canyon Lake Marina. At the Marina, Victim received first aid from Lake Staff until Scales Mound Fire and Warren Ambulance arrived and transported him to the Monroe, WI hospital. Victim was later transported from Monroe to Madison, WI for treatment.
