"He's expected to live," Detective Lt. Ronald Klein Jr. said. "He's just a little out of it."
Two workers in a Ridgefield Park warehouse spotted the man, who was wearing a t-shirt, underwear, socks and sneakers, Klein said.
He wasn't carrying any ID, the lieutenant said.
A Ridgefield Park Fire Department boat pulled the man toward the shore at Gates Road, Klein said.
Little Ferry firefighters then tossed ropes, pulled the boat in and carried the man to safety, he said. They administered first aid until paramedics arrived.
Borough detectives later interviewed him at Hackensack University Medical Center.
