Which site was the heritage designation of United States lightship Swiftsure (LV-83) between Mar 1987 and Jan 1988?
United States lightship Swiftsure ( LV-83 ) Light Vessel Number 83 ( LV-83 ) Swiftsure is a lightship and museum ship owned by Northwest Seaport in Seattle , Washington . Launched in 1904 at Camden , New Jersey and in active service until 1960 after serving on all five of the American west coasts lightship stations , it is the oldest surviving lightship in the United States , the only one still fitted with its original steam engine , and the last lightship with wooden decks . LV-83 was designated a National Historic Landmark in 1989 , and has been undergoing major restoration since 2008 . Description . As built , LV-83 was one of the nations new third-generation lightships , with an all-steel hull , wooden decks , and a powerful double-expansion steam engine . It measured on the keel , 133 feet overall , with a beam of and a draft of , and was rated at 668 tons . The beakhead roller on the bow was later removed , reducing length overall to 129 feet 6 inches . The ships aids to navigation currently include a 1,000-watt beacon light , a 140-decibel Diaphone horn , and a foredeck fog bell . At the time of launching , however , the beacon consisted of a chandelier of three oil lamps that could be hoisted up the masts from the deck . These were originally powered by whale oil , then first converted to kerosene , and finally electrified in 1930 . A 12-inch diameter steam whistle was the primary sound signaling device on board with the 1,000-lb bell standing by as the auxiliary . For a time , LV-83 was also fitted with an underwater bell with a mechanical striker that would strike out the ships identity as a submarine signal . Sound carries much farther in water , extending the range of the ships signals . The underwater bell was removed when a radio beacon was fitted on the ship for long-range signaling . For propulsion , LV-83 was driven by a single 8-foot diameter screw powered by a 375-horsepower marine steam engine , originally fed by a pair of coal-fired fire-tube Scotch boilers . The ship had two coal bunkers , each with a capacity of 75 tons , and freshwater tankage for more than 11,000 gallons . In 1934 , the Scotch boilers were replaced with modern oil-fired watertube boilers , improving endurance , speed of bunkering , and speed in raising steam while simultaneously reducing the size of the boiler room crew . During active service , LV-83s normal crew complement was 15 , with 10 on duty at any given time . The others were on shore leave rotation . Crew size did fluctuate slightly with technological modifications such as the labor saving oil-fired boilers or the successive waves of new electronic devices like radio and radar . During World War II , the ships complement increased to more than 30 to man the guns fitted aboard for war duty . History . LV-83 was launched in Camden , New Jersey in 1904 , and was deployed to the West Coast to serve on the Blunts Reef lightship station . Since the Panama Canal would not be completed for another decade , LV-83 ( accompanied by LV-76 ) had to steam around the tip of South America and north to San Francisco to reach its first station assignment at Blunts Reef off Crescent City , California . While there , the ship rescued 150 people from the steamer Bear after that ship ran aground on the reef in dense fog . Formerly known as Relief , LV-83 had numerous names on its sides , all of which indicated the location of its station . Swiftsure refers to the Swiftsure Bank near the entrance to the Strait of Juan de Fuca , which separates Washington from Vancouver Island . She also guided ships near Umatilla Reef and the Columbia River Bar . The ship was decommissioned in 1960 , and purchased by Northwest Seaport in 1966 . It is listed on the National Register of Historic Places , was declared a National Historic Landmark in 1989 , and is on the Washington State Heritage Register . LV-83 is docked on Lake Union , in Seattle , Washington , where a long-running restoration was begun in 2008 . LV-83 is open to visitors on most summer weekends , or by appointment .
