RedactedNarrative: I, Ofc., responded to Lake Sylvia in reference to a boat accident. While en route I spoke with an anonymous witness by phone and she stated that a boat just hit a dock and other boats, Operator was attempting to call for police on VHF Ch 16. Upon arrival 1 spoke with Operator and he stated that they were anchored in the lake for most of the day. 
  
  He stated that when they were ready to leave the anchor was stuck. He stated he put the boat in neutral and left the cabin to assist with getting the anchor. As soon as the anchor was freed the boat lunged forward. 
  
  Operator ran to the cabin and attempted to stop the boat. He stated he was able to slow it down prior to impact. Operator stated that he allowed some of the kids to play in the upstairs cabin and they must have left the throttle in forward. He stated it was his mistake for not checking. Operator was given the case number. 
  
  Damage to Operator's vessel: Port side two punctures and scratches. Approximate damage amount $10,000. Property Owner #1: Damage to a cement piling, cement dock and an aluminum gate. 53,000.00, Property Owner #2: Harbor Beach Surf Club Marina. Damage to an electrical box, wooden dock, two wooden pilings. Approximate damage amount $5,000.00.
