Three Dracut men, along with friends from Chelmsford and Lynnfield, are the talk of the town after reeling in a 920-pound bluefin tuna during a recent fishing expedition off the coast of Gloucester. Gregg Looney, Brian Keefe, and Michael St. Jean chartered a boat with friends Allan Gourley and Brian Shaffer under the guidance of Captain Kevin Leonowert. Leonowert is known to many from the National Geographic Channel reality show “Wicked Tuna,” which is based in Gloucester. The men worked for three hours and covered over 4 miles of sea before the tuna was brought on board. It was sold to a Gloucester seafood company; the men say they will make the same trip next year to try their luck again.
