Tuff-E-Nuff, originally known as Thomas Cunningham Sr., was a late 19th-century tugboat which has had a remarkable 112-year commercial career. She was still operating as a working tugboat as recently as May 2007. She was sunk as an artificial reef in January 2011. 
Thomas Cunningham Sr. was built in 1895 by Neafie & Levy of Philadelphia, Pennsylvania for the Army Corps of Engineers. She was operated by the Harbour Board of the Port of Richmond, Virginia for more than eighty years.
After 45 years of service, Thomas Cunningham Sr. was sent to Newport News for the annual inspection where she was placed into "durance vile"—meaning the vessel was considered unsafe to operate. Her papers were seized and she was suspended from duty until repairs were made. The main complaint was deck issues. The Richmond City Council quickly approved the budget extension for $8,000 to get the repairs completed  and get their tug back.
Starting in late 1948, Thomas Cunningham Sr. finally got a much needed major refit. The wooden pilot house and deck were replaced with steel versions, and a 500 horsepower (370 kW) Cleveland 8-268A diesel engine was installed to replace the original steam engine. The entire cost of the project, including sending two maintenance people to the Cleveland factory for training, was $65,927.02. Out of the nine bidders for the work, Dunn's Marine Railway, Inc. of West Norfolk won the bid and completed the work approximately $11,000 under budget.
In 1977 the vessel was sold into private hands, and reportedly became a salvage tug in Florida. In May 2007, the tug was placed on the market by her owners, a salvage company, who were hoping to sell her to restorers. As of 2008, she was registered as a recreational vessel according to the U.S. Coast Guard's Port State Information eXchange.
On 17 January 2011, Tuff-E-Nuff was placed off St. Lucie, Florida as the Kyle Conrad Memorial Reef.
Mariners Museum collection
In 1951, the ship's original engine was acquired by the Mariners' Museum at Newport News, Virginia. The engine has since been restored to working order—albeit powered by electricity rather than steam—and was recently taken off exhibition and put into storage at the museum.
The engine is a two-cylinder compound type with an 18-inch (46 cm) stroke, and 206 indicated horsepower (154 kW). The high-pressure cylinder is 12 1⁄2 inches (32 cm) in diameter and the low-pressure cylinder is 24 inches (61 cm). The engine weighs approximately 14 tons and stands 10 feet 1 1⁄2 inches (3.086 m) high.
