PWC traveling east saw a vessel coming toward his starboard side, he turned PWC towards port (left) to avoid that vessel hitting him.  At the same time, a vessel driven by his wife, who was also traveling east across the reservoir, saw several boats coming towards her port side, she made a sharp turn of her vessel starboard to avoid a path of collision.  The PWC operator was looking towards the vessel he was trying to avoid, and when he looked ahead, he struck the vessel which was being operated by his wife.
