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.
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.
Northwest Seaport Maritime Heritage Center is a nonprofit organization in Seattle, Washington dedicated to the preservation and interpretation of Puget Sound and Northwest Coast maritime heritage, expressed through educational programs and experiences available to the public aboard its ships. The organization owns three large historic vessels docked at the Historic Ships' Wharf in Seattle's Lake Union Park; the tugboat Arthur Foss (1889), Lightship 83 Swiftsure (1904), and the halibut fishing schooner Tordenskjold (1911). These vessels are used as platforms for a variety of public programs, ranging from tours and festivals to restoration workshops and vocational training.
A lighthouse tender is a ship specifically designed to maintain, support, or tend to lighthouses or lightvessels, providing supplies, fuel, mail, and transportation.
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.
The United States lightship Huron (LV-103) is a lightvessel that was launched in 1920. She is now a museum ship moored in Pine Grove Park, Port Huron, St. Clair County, Michigan.
United States lightship Columbia (WLV-604) is a lightship located in Astoria, Oregon, United States of America. Columbia was formerly moored near the mouth of the Columbia River.
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 coast's 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.
Lightship Ambrose was the name given to multiple lightships that served as the sentinel beacon marking Ambrose Channel, New York Harbor's main shipping channel.
Cape Mendocino Light was a navigation light at Cape Mendocino, California. The former lighthouse was relocated to Shelter Cove near Point Delgada, California in 1998, and the historic Fresnel lens to Ferndale, California, in 1948. An automated beacon operated for a number of years but was removed in May 2013.
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.
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.

She received little maintenance, and eventually sank at her moorings in 2006 and was sold for scrap the next year.
