Adding, "It happened many, many times before, and I had always gone out and pulled the ropes tighter to keep the dinghy flush against the yacht. She probably skidded on one of the steps after untying the ropes. The steps are slick as ice because of the algae and seaweed that's always clinging to them. After slipping on the steps, she hit her head against the boat. I only hope she was unconscious when she hit the water."
