Built in 1978, at Jakobson Shipyard of Oyster Bay, New York (hull #458) as the Harriet Moran for the Moran Towing Company of New York, New York.
In the mid to late 1990's, the tug was modified with a 640 horsepower retractable forward Nautican high performance propeller nozzle or "z-drive" to augment her original single screw configuration. The new nozzle and propeller were expected to improve bollard pull by 35 to 40 percent. Her original propeller was removed and replaced with a triple vane rudder system that is intended to increase general maneuverability.
The tug was fitted with a new JonRie Intertech hawser winch on her stern. Original design work on Moran's conversions was done by naval architect Paul Gow, the new class of tugs was dubbed the MORtrac class tug.
The tug does most of its ship assist work with the stern to the ship, thus allowing the forward "z-drive" to contribute to maneuvering the tug while adding horsepower to any maneuver.
She is rated at 3,005 horsepower.
