RedactedNarrative: On June 21, 2014 at 1352 hours I received a call from Bartow County SO in reference to a boat incident on Allatoona Lake at Upper Stamp Creek.  Dispatch advised that a vessel was struck by a PWC and both parties were at campsite #18.  I immediately responded with Bartow County unit #938.  I located operator2, he advised that he and his wife were traveling downstream near the swimming area and saw a blue PWC coming straight at them.  Operator2 stated that the Hispanic male operator did not look up until the last second.  Operator2 stated he sped up in an effort to get out of the way of the oncoming vessel, but the PWC hit his boat near the rear on the port side.  There was major fiberglass damage at the rub rail area of Operator2's vessel.  He advised that it appeared that no one was injured in the incident. I located the operator of the PWC.  Operator1 did not speak English very well.  Operator1 stated he was traveling upstream and could not stop in time to miss the other boat, driven by Operator2.  Both parties involved pointed out the area of the incident.  The location was just downstream of the swimming and beach area at the campground.  There is a small island in the area that creates a blind point.  Based on statements from both parties Operator1 came around the blind point on the left side of the channel and struck Operator2's vessel.  I checked the equipment on both vessels.  Operator2's vessel was in compliance. The PWC operated by Operator1 was found to be unregistered and did not have a fire extinguisher onboard.  All parties involved gave written statements.  I issued Operator1 citations for operating a vessel without registration and Violation Rules of the Road.
