Her Story
Katie G. McAllister was constructed in 1966 by Gulfport Shipbuilding Corp. of Gulfport, Texas, as Hull #671. She is 124’ long, 31’06’’ wide, and 13’08’’ deep, and powered by a pair of GM EMD 12-645-E5 diesel engines, producing 4300 BHP. She was built as the Libby Black for Gulfcoast Transit, a subsidiary of Tampa Electric Co. She was delivered to her new owners July 1966, and paired with the barge Barbara Vaught. The pair were tasked with delivering coal from ports near the mouth of the Mississippi River to Tampa Electric’s power plants at Tampa, Florida.
Libby Black was sold to McAllister Towing & Transportation of New York, New York, in 2003. She was renamed Katie G. McAllister, and operated as a harbor tug at New York Harbor.
In 2016, Port City Marine Services of Muskegon, Michigan, a subsidiary of Sand Products Corporation, purchased the Katie G. and her sister Colleen McAllister. The two tugs set off from layup at Staten Island in December, passing through the St. Lawrence Seaway later in the month. The tow arrived at Muskegon on Christmas Eve, and the tugs were laid up at the Mart Dock. Katie G. McAllister remains in layup at Muskegon.
