"If I hadn't gotten into my slip fast enough, I believe he would have run me over," Ferrelle told police.
Ferrelle and his passengers told police Currington pulled up to the dock, but didn't get out of his boat. They said he called Ferrelle foul names and said, "I am going to (expletive) you up you mother (expletive) old man," according to the police affidavit. It says Currington told Ferrelle that he and his brother would "catch him in the river" and "finish him off."
Ferrelle did not immediately return phone messages from The Associated Press. One of his passengers, Curt Reinelt, declined to comment when reached by phone Thursday.
A second charter boat captain, Elizabeth Johnson, later told police Currington made similar threats to her and a passenger last October when they were fishing not far from the singer's home.
A separate police report filed soon after the incident indicates that those living at Currington's home had problems with boats passing by too closely or too fast. A woman who said she was the caretaker of an elderly man at the same address called police to complain that a passing boat nearly knocked the man off the home's dock and into the water. The police report said the woman was talking about the events that led to Currington chasing after the tour boat.
"Well, what is it we can do to keep people from coming up on our docks or swamping our docks?" the woman asked.
Currington told The Tennessean newspaper in 2007 that he sometimes struggled to control his anger as a result of suffering childhood abuse while growing up in Rincon, near Savannah. In the interview, conducted after he completed a 30-day trauma recovery program in Arizona, Currington said a small part of him remained "hurt, sad and furious."
"When he comes out, he comes out very quickly and it goes away very quickly," Currington told the newspaper. "And in those instances, that rage can destroy relationships, whether it's with a girlfriend or a business partner or a fan. It doesn't take long to screw it all up."
