“She started to sink,” Mr Koen told local news outlet NorthJersey.com. “I just jumped in the water and supported her while I got a line under her arms.”
He drove the boat back to shore, and the woman from New Jersey is now recovering from a broken leg and trauma at Mount Sinai St. Luke’s Hospital in Manhattan.
Including the woman, only two out of the 97 people who have jumped from the bridge since 2009 have survived.
Mr Koen was also involved in the “Miracle on the Hudson” rescue in January 2009 as a volunteer firefighter.
After both engines failed on US Airways Flight 1549 and Captain Chesley Sullenberger was forced to make an emergency landing on the river in New York, Mr Koen helped passengers off the plane and on to his boat.
The search for New Square resident Mr Ahronowitz, who committed suicide on January 22 aged 46, continues.
