RedactedNarrative: Watercraft #1 was towing a wake boarder. The water ballast in the boat was too full, and the rear of the boat was too low in the water. The wake boarder fell and when the operator turned the boat to recover the wake boarder, a wake from another boat washed over the transom of Watercraft #1 causing it to flood and sink. All four occupants were able to put on life jackets and there were no injuries. Operator #1 stated he had purchased the boat from another man approximately a year ago, but had not transferred the registration into his name yet. The boat was recovered on 7/7/17.
