A lightvessel, or lightship, is a ship that acts as a lighthouse. They are used in waters that are too deep or otherwise unsuitable for lighthouse construction. Although some records exist of fire beacons being placed on ships in Roman times, the first modern lightvessel was off the Nore sandbank at the mouth of the River Thames in London, England, placed there by its inventor Robert Hamblin in 1734. The type has become largely obsolete; lighthouses replaced some stations as the construction techniques for lighthouses advanced, while large, automated buoys replaced others.
The history of the many lightvessel stations of Great Britain goes back over 250 years to the placement of the world's first lightship at the Nore in the early 18th century.
United States lightship Chesapeake (LS-116/WAL-538/WLV-538) is a museum ship owned by the National Park Service and on a 25-year loan to Baltimore City, and is operated by Historic Ships in Baltimore Museum in Baltimore, Maryland. A National Historic Landmark, she is one of a small number of preserved lightships. Since 1820, several lightships have served at the Chesapeake lightship station and have been called Chesapeake. Lightships were initially lettered in the early 1800s, but then numbered as they were often moved from one light station to another. The name painted on the side of lightships was the short name of the Light Station they were assigned to and was the daytime visual aspect of the many Aids to Navigation on board lightships. The United States Coast Guard assigned new hull numbers to all lightships still in service in April 1950. After that date, Light Ship 116 was then known by the new Coast Guard Hull number: WAL-538. In January 1965 the Coast Guard further modified all lightship hull designations from WAL to WLV, so Chesapeake became WLV-538.
The United States Lighthouse Service, also known as the Bureau of Lighthouses, was the agency of the United States Government and the general lighthouse authority for the United States from the time of its creation in 1910 as the successor of the United States Lighthouse Board until 1939 when it was merged into the United States Coast Guard. It was responsible for the upkeep and maintenance of all lighthouses and lightvessels in the United States.
The station named Nantucket or Nantucket Shoals was served by a number of lightvessels that marked the hazardous Nantucket Shoals south of Nantucket Island. The vessels, given numbers as their "name," had the station name painted on their hulls when assigned to the station. Several ships have been assigned to the Nantucket Shoals lightship station and have been called Nantucket. It was common for a lightship to be reassigned and then have the new station name painted on the hull. The Nantucket station was a significant US lightship station for transatlantic voyages. Established in 1854, the station marked the limits of the dangerous Nantucket Shoals. She was the last lightship seen by vessels departing the United States, as well as the first beacon seen on approach. The position was 40 miles (64 km) southeast of Nantucket Island, the farthest lightship in North America, and experienced clockwise rotary tidal currents.
Uriel Sebree was a career officer in the United States Navy. He entered the Naval Academy during the Civil War and served until 1910, retiring as a rear admiral. He is best remembered for his two expeditions into the Arctic and for serving as acting governor of American Samoa. He was also commander-in-chief of the Pacific Fleet.
USS Barricade (ACM-3) was a Chimo-class minelayer in the United States Navy during World War II.
The United States Coast Guard Cutter Fir was the last lighthouse tender built specifically for the United States Lighthouse Service to resupply lighthouses and lightships, and to service buoys. Fir was built by the Moore Drydock Company in Oakland, California in 1939. On 22 March 1939, the U.S. Lighthouse Tender Fir was launched. She was steam driven with twin screws, 175 feet (53 m) in length, had a beam of 32 feet (9.8 m), drew 11 feet 3 inches (3.43 m) of water, and displaced 885 tons. Fir was fitted with a reinforced bow and stern, and an ice-belt at her water-line for icebreaking. She was built with classic lines and her spaces were lavishly appointed with mahogany, teak, and brass. The crew did intricate ropework throughout the ship. The cost to build Fir was approximately US$390,000. Fir's homeport was Seattle, Washington for all but one of her fifty one years of service when she was temporarily assigned to Long Beach, California when USCGC Walnut was decommissioned on 1 July 1982.
United States lightship Nantucket (LV-112) is a National Historic Landmark lightship that served at the Lightship Nantucket position. She was the last serving lightship and at time of its application as a landmark, one of only two capable of moving under their own power. She served as the lightship for such notable vessels as the liners United States, Queen Mary, and Normandie.
USLHT Azalea was built as a lighthouse tender and performed in that role on the Massachusetts coast from 1891 to 1917 and again from 1919 to 1933. During World War I, she served in the United States Navy as USS Azalea. Between the wars she was a commercial freighter in Chesapeake Bay, and later between Florida and The Bahamas. During World War II, she was reacquired by the U.S. Navy and served as USS Christiana, a seaplane tender which supported advanced bases in The Bahamas. Declared surplus in 1946, she was sold to Banana Supply Company, and spent a decade transporting bananas from the Caribbean to Miami. After 1956 her history is uncertain until she became a half-sunk derelict and was scrapped in Miami in 1965.
LV-117 was a lightvessel of the United States Lighthouse Service. Launched in 1931, she operated as the Nantucket lightship south of Nantucket Shoals. Moored south of Nantucket Island, Massachusetts, the lightship was at the western part of the transatlantic shipping lane and the first lightship encountered by westbound liners approaching New York Harbor. On May 15, 1934, one of these liners, RMS Olympic, rammed and sank LV-117, killing seven of her crew.
USRC Onondaga was an Algonquin-class cutter built for the U.S. Revenue Cutter Service for service on the Great Lakes. Because of the Spanish–American War, she was cut in half shortly before completion and transported to Ogdensburg, New York for service on the Atlantic coast although the war ended before she could be put into service. After the formation of the United States Coast Guard in 1915 she became USCGC Onondaga. She served as a patrol vessel at various Atlantic coast ports before World War I and unlike most Coast Guard cutters during World War I, she remained under the control of the Commandant of the Coast Guard. After the war she patrolled for a brief time based at New London, Connecticut before being decommissioned in 1923.
USRC Mohawk, was a steel steam powered revenue cutter built for the U.S. Revenue Cutter Service by William R. Trigg Company at Richmond, Virginia. Her primary duties in the Revenue Cutter Service and Coast Guard were assisting vessels in distress and enforcing navigational laws as well as a derelict destroyer. Mohawk was sunk after a collision with another vessel in October 1917.
USCGC Citrus (WAGL-300/WLB-300/WMEC-300) was a Cactus (A)-class seagoing buoy tender built in 1942 in Duluth, Minnesota, and now operated by the navy of the Dominican Republic.
USCGC Clover WAGL/WLB/WMEC-292, a Cactus (A) Class buoy tender was built by Marine Iron and Shipbuilding, Duluth, Minnesota. Her keel was laid 3 December 1941, and she was launched 25 April 1942. She was commissioned on 8 November 1942 in the United States Coast Guard as the United States Coast Guard Cutter Clover. She was built as a WAGL, redesignated a WLB in 1965, and again redesignated a WMEC in 1979.
The United States Lightship WLV-613 was a lightvessel commissioned in 1952 that became the last lightship to mark the Ambrose Channel. She was replaced by a Texas Tower lightstation on 24 August 1967.
USCGC Cape Horn was a 95-foot (29 m) type "C" Cape-class cutter constructed at the Coast Guard Yard at Curtis Bay, Maryland, in 1958 for use as a law enforcement and search and rescue patrol boat.
The Nantucket Lightship or United States Lightship WLV-612 is a lightvessel commissioned in 1950 that became the last lightship decommissioned in United States Coast Guard service.
USRC Gresham was a cruising cutter and auxiliary gunboat built for the United States Revenue Cutter Service to patrol the Great Lakes. She was one of a series of cutters named for former U.S. Secretaries of the Treasury. Her namesake Walter Q. Gresham served as the 35th Secretary of the Treasury in 1884 and died in 1895 while serving as the 33rd U.S. Secretary of State. She became part of the newly created United States Coast Guard in 1915, and also served as a coastal convoy escort and patrol boat under United States Navy control during both World War I and World War II. After being decommissioned by the Coast Guard in 1944, she eventually came under Israeli control in 1947. She carried Jewish refugees from Italy to Palestine and later served in the fledgling Israeli Navy until 1951.
USS YF-416 was an American YF-257-class covered lighter built in 1943 for service in World War II. She was later acquired by the United States Coast Guard and renamed USCGC White Sumac (WAGL-540).
