Lightship Overfalls (LV-118) (later renumbered WAL-539) was the last lightvessel constructed for the United States Lighthouse Service before the Service became part of the United States Coast Guard.[2] She is currently preserved in Lewes, Delaware as a museum ship.


This ship was built to replace LV-44, badly damaged in the New England Hurricane of 1938, for the Cornfield Point station.[3] Patterned after the LV-112,[2] she has a hull unlike that of any of her sisters; in effect, a single-ship class.[4] She is the last riveted-hull lightship built for the United States Lighthouse Service, all subsequent ships having welded hulls. Propulsion was diesel, with a set of diesel generators and compressors providing power for the beacon and auxiliaries.[2][5] The light was a duplex 375 mm (14.8 in) lantern on a single mast, at 57 ft (17 m) above the water line.[5] Dual diaphones were provided for a fog signal, as well as a bell and radiobeacon.[2] A radar unit was installed in 1943.[5] The crew complement was fourteen, to serve on a two weeks on/one week off basis.[5] When the lighthouse service was merged into the coast guard in 1939, she was renumbered WAL 539.[2]

LV 118 / WAL 539 served at these stations:[2]

1938-1957: Cornfield Point, Connecticut
1958-1962: Cross Rip, Massachusetts
1962-1972: Boston, Massachusetts

Unlike most US lightships WAL 539 remained on station during World War II.[4] A severe storm in December 1970 damaged the ship, leading to her decommissioning on November 7, 1972.[6] Upon retirement WAL 539 was donated to the Lewes Historical Society and placed on display in Lewes, Delaware, painted for the "OVERFALLS" station, though she never served there.[4] The Lightship that actually served on the Overfalls station, is on display in Portsmouth Virginia. The ship's condition deteriorated and a failed attempt in 1999 to sell her led to the formation of a separate group, the Overfalls Maritime Museum Foundation, to take over the maintenance and restore the vessel.[7] She remains in Lewes and is available for tours.[7]

The lightship was placed on the National Register of Historic Places in 1989, and in 2011 was further designated a National Historic Landmark.[8]
