Operator was using his father's boat to take kids waterskiing. It was his nephew's turn, but his nephew's ski came off. Operator's wife got into the water to help nephew get his ski back on. In the meantime, the operator started pulling his daughter on skis. When they came into the dock to drop his daughter off, she didn't let go. Operator was already turning back out into the lake, yelling at his daughter to let go and realized he couldn't see his wife or nephew. He tried to swerve to miss them and felt the watercraft hit something. The motor shut off and he realized that he had hit them (unsure if with the propeller). He yelled to shore to call 911, jumped in the water to pull nephew out. His wife was also hit, but didn't appear to have any injuries and refused medical treatment.
