Standard Oil Company No. 16, later Pegasus, was a historic harbor tugboat located at Morris Canal Basin, Jersey City, New Jersey. She was built in 1907 by the Skinner Shipbuilding and Dry Dock Company of Baltimore, Maryland for the Standard Oil Company. She had heavy steel frames and deck beams. She was 100 feet in length, 23 feet in beam and 11.2 feet in depth. She was registered at 175 gross tons. She had an original wooden pilot house and the engine room dated to 1953-1954 when converted from steam to diesel. At that time, Standard Oil sold the tug to the McAllister Towing and Transportation Company and she was renamed McAllister 41. In 1955, she was renamed John E. McAllister.
