RedactedNarrative: On and about july 3, 2021, at approximately 13:00, operator and passenger were on cruising on the cape fear river at lock and dam #3 near fayetteville/hope mills. On the way up river before arriving at the ramp, two witnesses who were fishing from the bank had brief interactions with operator and could tell he had been drinking alcohol. Operator was waiting his turn at the ramp. During this time operator's motor (was) turned off and the boat began drifting toward the dam. Operator was not aware of his vessel's trajectory nor distance to the dam. The vessel then capsized from the water pouring over the dam and both operator and passenger were ejected into the water. Operator managed to pull himself onto the hull of the capsized vessel while passenger was pulled under at least three times by the undertow before operator threw her a pfd. Passenger was pulled under once more while holding on to the pfd, but was grabbed by operator who started yelling for help. Operator held passenger above water and to the side of the capsized vessel for approximately forty minutes when they were rescued by hope mills search and rescue.
