Gulf Spray trots along light at hull speed, bound for the cruise ship Veendam at Pier 22.
Full out, the tug wrangles a pair of scows with assistance from its companion motorboat (a small tank scow is barely visible on the offside of the larger scow). Working in a stiff breeze, the tow is going more sideways than in the direction of Pier 9A where the various waste products will be landed for disposal.
Gulf Spray was built in 1959 by Ferguson's Industries Ltd in Pictou for shipyard work. Brought to Halifax and rebuilt in 2007, it was badly damaged in a storm in 2014 and partially rebuilt.
