Both vessels were at the lake together.  The pontoon boat (Vessel 2) was drifting.  The Hydrosport (Vessel 1) was pulling a tube.  As the Hydrosport pulled up to the pontoon boat, the tube''s momentum carried it into the port side of the pontoon boat.   The occupant of the tube then struck the pontoon resulting in an injured right leg.  He was transported to Henry County Medical Center by EMS where he was treated and released for a deep bruise to the right thigh.
