Wolf Scout Ben Nathan, 7, of Hallowell blows his sailboat Thursday during Raingutter Regatta that Cub Scout Pack 647 held in Farmingdale.  Over 20 scouts from Hallowell and Farmingdale competed in races with the balsa wood vessels they constructed with six inch masts during the event.  Powered by blowing the sail, winners were determined by which boat arrived at the end of a rain gutter first.
