Thames Tow Boat Company, Foot of Farnsworth Street, New London, New London County, CT
Significance: The Thames Shipyard has been in constant use from the time of its completion in 1903 to the present (as of 1978). Originally constructed to build and repair ocean-going tugs and barges, the yard served as a submarine maintenance base in World War I and World War II. Few major alterations have been undertaken at the yard. It remains a complete, surviving example of a wooden shipbuilding and repair facility, and contains the oldest known steam powered marine railway in the U.S.

Steam Machines, Engines, Locomotives. In 1781 James Watt patented a steam engine that produced continuous rotary motion. Watt's ten-horsepower engines enabled a wide range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained. By 1883, engines that could provide 10,000 hp had become feasible. The steam engine was one of the most important technologies of the Industrial Revolution.
