On july 4, 2013, two pwcs were travelling south in "horseshoe bend" of lake tillery.  The two pwcs were traveling between 21-40 mph and were very close to each other.  As they were cruising, vessel 2 abruptly turned in front of vessel 1.  The operator of vessel 1 tried to turn, but let off the throttle causing her to lose all steering of the pwc.  Vessel 1 then struck vessel 2 hard on the port side.  Both operators were thrown into the water.  Neither operator received serious injuries.
This accident was caused by careless operation and inattention to where each vessel was on the water.  Had the vessels been far enough away from each other, they would never have collided when vessel 2 abruptly turned.  Also, the operator of vessel 2 was unaware of the location of vessel 1 when he abruptly turned.
