Vessel 1 was traveling upstream (west/northwest) on lake shafer near the tippecanoe countrty club when he advised that he heard a women yell behind his boat.  At nearly the same time operator 1's wife, who was in a backward facing seat, let out a yell as well as she saw a pwc quickly advancing toward the back of their boat.  Operator 1 advised that when he heard the shouts he turned around and saw vessel 2 about to crash into the stern of his boat.  In an attempt to avoid a collision operator 1 quickly accelerated but could not avoid vessel 2.  Operator 2 advised a similar explanation.  Operator 2 advised that she was distracted by the rough water and wake from other boats and that when she looked in front of her vessel 1 just appeared to 'come out of nowhere" and she collided with the vessel.  Vessel 1 had several small cracks in the fiberglass on the stern on the port side and a small tear in the upholstery of the back seat.  Vessel 2 also sustained some minor fiberglass damage on the front port side of the machine and the rubber rub rail also had some minor damage.  As a result of this investigation operator 2 was arrested for operating  a motorboat with a driver's license status of suspended/prior and was issued a second infraction citation for imprudent operation for following vessel 1 too closely.
