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.
The Elizabeth River is a 6-mile-long (10 km) tidal estuary forming an arm of Hampton Roads harbor at the southern end of Chesapeake Bay in southeast Virginia in the United States. It is located along the southern side of the mouth of the James River, between the cities of Portsmouth, Norfolk, and Chesapeake. Forming the core of the Hampton Roads harbor, it is heavily supported by its tributaries which depend upon it.
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 Battle of Craney Island was a victory for the United States during the War of 1812. The battle saved the city of Norfolk, and the adjacent city of Portsmouth, from British invasion. Especially important to Virginia and northeastern North Carolina, the region was a major hub for American commerce.
Craney Island is a point of land in the independent city of Portsmouth in the South Hampton Roads region of eastern Virginia in the United States. The location, formerly in Norfolk County, is near the mouth of the Elizabeth River opposite Lambert's Point on Hampton Roads. It is home to the Craney Island US Naval Supply Center, managed by the U.S. Army Corps of Engineers.
Ambrose Light, often called Ambrose Tower, was the light station at the convergence of several major shipping lanes in Lower New York Bay, including Ambrose Channel, the primary passage for ships entering and departing the Port of New York and New Jersey.
A Texas Tower lighthouse is a structure which is similar to an off-shore oil platform. Seven of these structures were built in the 1960s off the shores of the United States. Automation started in the late 1970s, which led to the obsolescence of the housing built for the keepers which resulted in such a large structure. Three of the towers were dismantled over time due to deteriorating structural conditions among other problems, while another one was destroyed in a ship collision. The last Texas Tower was deactivated in 2016 having served for over half a century. Today only three of the former lights remain.
Stratford Shoal Light, officially Stratford Shoal Light, is a lighthouse on a shoal in the middle of Long Island Sound approximately halfway between Port Jefferson, New York and Bridgeport, Connecticut.
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.
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.
Thimble Shoal Light is a sparkplug lighthouse in the Virginia portion of Chesapeake Bay, north of the Hampton Roads channel. The third light at this location, it is listed on the National Register of Historic Places.
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.
The Windmill Point Light was a lighthouse located at the mouth of the Rappahannock River.
Smith Point Light is a caisson lighthouse in the Virginia portion of the Chesapeake Bay at the mouth of the Potomac River. It was added to the National Register of Historic Places in 2002.
The Bowlers Rock Light was a lighthouse located in the Rappahannock River in Virginia.
Chesapeake Light is an offshore lighthouse marking the entrance to the Chesapeake Bay. The structure was first marked with a lightship in the 1930s, and was later replaced by a "Texas Tower" in 1965. The lighthouse was eventually automated and was used for supporting atmospheric measurement sites for NASA and NOAA. Due to deteriorating structural conditions, the lighthouse was deactivated in 2016. At the time it was the last remaining "Texas Tower" still in use due to obsolescence.
The Hog Island Light was a lighthouse roughly marking its eponymous island, and thus the north side of the Great Machipongo Inlet on the Virginia coast. Originally, no light existed between Cape Henlopen, Delaware and Cape Charles, Virginia. In 1830 the United States Congress appropriated money for a coastal beacon in the general vicinity of Chincoteague Island. The following year, the Collector of Customs in Norfolk selected Assateague Island.
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.
USC&GS Drift was a United States Coast Survey schooner built in 1876 specifically to anchor in offshore waters to undertake current measurements. She was transferred to the United States Lighthouse Board on May 20, 1893 to become the lightship Light Vessel # 97 or (LV-97) on the Bush Bluff station until retirement and sale in 1918 to become the W. J. Townsend which was scrapped in 1945.
