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 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.
USS Pampanito (SS-383/AGSS-383), a Balao-class submarine, was a United States Navy ship, the third one named for the pompano fish. She completed six war patrols from 1944 to 1945 and served as a United States Naval Reserve training ship from 1960 to 1971. She is now a National Historic Landmark, preserved as a memorial and museum ship in the San Francisco Maritime National Park Association located at Fisherman's Wharf in San Francisco, California.
USS Constellation is a sloop-of-war, the last sail-only warship designed and built by the United States Navy. She was built at the Gosport Shipyard between 1853 and 1855 and was named for the earlier frigate of the same name that had been broken up in 1853. The sloop's primary armament was 8-inch (203 mm) shell-firing guns and four 32-pounder long guns, though she carried other guns as well, including two Parrott rifle chase guns. Constellation's career as a front-line unit was relatively short; after entering service in 1855, she served with the Mediterranean Squadron until 1858, and in 1859, she was assigned as the flagship of the Africa Squadron, where she served with the African Slave Trade Patrol. During the American Civil War (1861–1865), the ship returned to the Mediterranean to patrol for Confederate vessels. In late 1864, she returned to the United States to be decommissioned, as most of her crews' enlistments had expired. She spent the rest of the war out of service.
The Inner Harbor is a historic seaport, tourist attraction, and landmark of the city of Baltimore, Maryland. It was described by the Urban Land Institute in 2009 as "the model for post-industrial waterfront redevelopment around the world". The Inner Harbor is located at the mouth of Jones Falls, creating the wide and short northwest branch of the Patapsco River. The district includes any water west of a line drawn between the foot of President Street and the American Visionary Art Museum.
USS Torsk, hull number SS-423, is a Tench-class submarine built for the United States Navy during World War II. Armed with ten torpedo tubes, the Tench-class submarines were incremental developments of the highly-successful Gato-class submarines that formed the backbone of the US Navy's submarine force during the war. Torsk was laid down at the Portsmouth Navy Yard in June 1944, was launched in September that year, and commissioned in December.
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 day time 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 Seven Foot Knoll Light was built in 1855 and is the oldest screw-pile lighthouse in Maryland. It was located atop Seven Foot Knoll in the Chesapeake Bay until it was replaced by a modern navigational aid and relocated to Baltimore's Inner Harbor as a museum exhibit.

United States Lightship 101, now known as Portsmouth as a museum ship, was first stationed at Cape Charles, Virginia. Today she is at the Portsmouth Naval Shipyard Museum in Portsmouth, Virginia. Portsmouth never had a lightship station; however, when the vessel was dry docked there as a museum, she took on the pseudonym Portsmouth. A National Historic Landmark, she is one of a small number of surviving lightships.
Helen Delich Bentley Port of Baltimore is a shipping port along the tidal basins of the three branches of the Patapsco River in Baltimore, Maryland on the upper northwest shore of the Chesapeake Bay. It is the nation's largest port facilities for specialized cargo and passenger facilities. It is operated by the Maryland Port Administration (MPA), a unit of the Maryland Department of Transportation.
Wolf Trap Light is a caisson lighthouse in the Virginia portion of the Chesapeake Bay, about seven and a half miles northeast of New Point Comfort Light. It is listed on the National Register of Historic Places.
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.
Frying Pan (LV-115) is a lightvessel moored at Pier 66a in the Chelsea neighborhood of Manhattan in New York City. It served at Frying Pan Shoals, off Cape Fear in North Carolina, for over 30 years.
United States lightship Relief (WLV-605) is a lightvessel now serving as a museum ship in Oakland, California. Built in 1950, she is one of a small number of surviving lightships, and one of an even smaller number built specifically for the United States Coast Guard. Along with her sister ship, the WLV-604 Columbia, she is a good example of the last generation of lightships built. She was declared a National Historic Landmark in 1989.
The Craney Island Light was a screwpile lighthouse located just east of Craney Island at the mouth of the Elizabeth River in Virginia. This light replaced the first permanently stationed lightship in the United States.
The United States lightship Barnegat (LV-79/WAL-506), is located in Camden, Camden County, New Jersey, United States. The lightship was built in 1904 and was added to the National Register of Historic Places on 29 November 1979.
Lightship Overfalls (LV-118) was the last lightvessel constructed for the United States Lighthouse Service before the Service became part of the United States Coast Guard. She is currently preserved in Lewes, Delaware as a museum ship.
