Abstract American Lightships, 1820-1983: History, Construction, and Archaeology within the Maritime Cultural Landscape by Morgan MacKenzie April, 2011 Director: Dr. Lawrence Babits DEPARTMENT OF HISTORY, PROGRAM IN MARITIME STUDIES In 1820, the United States Government began funding construction and conversion of watercraft for use as lightships. Floating beacons utilized to mark dangerous shoals, reefs, and shifting channels in inland as well as open waters, lightships served where lighthouse construction was unfeasible. This study intends to examine the general history of U.S. lightships, improvements to construction design, technological modifications in illumination and signaling, venue of employment, as well as use, re-use, and the maritime cultural landscape associated with these craft.

Employed as navigational aids, lightships were stationed along shipping lanes and intercoastal waterways in the Atlantic, Pacific, Gulf of Mexico, Great Lakes, and various estuarine environments in the Chesapeake, North Carolina, and the Pacific Northwest.
