Barge often refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but on inland waterways, most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges.
Maritime archaeology is a discipline within archaeology as a whole that specifically studies human interaction with the sea, lakes and rivers through the study of associated physical remains, be they vessels, shore-side facilities, port-related structures, cargoes, human remains and submerged landscapes. A specialty within maritime archaeology is nautical archaeology, which studies ship construction and use.
The Tiber is the third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing 406 km (252 mi) through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia and Fiumicino. It drains a basin estimated at 17,375 km2 (6,709 sq mi). The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks.
Ostia Antica was an ancient Roman city and the port of Rome located at the mouth of the Tiber. It is near modern Ostia, 25 km (16 mi)) southwest of Rome. Due to silting and the invasion of sand, the site now lies 3 km (2 mi) from the sea. The name Ostia derives from Latin os 'mouth'.
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium. On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to a ship whose propulsion system is no longer maintained, or has been removed altogether. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage.
Lake freighters, or lakers, are bulk carrier vessels that operate on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships.
Nemi is a town and comune in the Metropolitan City of Rome, in the Alban Hills overlooking Lake Nemi, a volcanic crater lake. It is 6 kilometres (4 mi) northwest of Velletri and about 30 kilometres (19 mi) southeast of Rome.
Portus was a large artificial harbour of Ancient Rome. Sited on the north bank of the north mouth of the Tiber, on the Tyrrhenian coast, it was established by Claudius and enlarged by Trajan to supplement the nearby port of Ostia.
The Port of New York and New Jersey is the port district of the New York-Newark metropolitan area, encompassing the region within approximately a 25-mile (40 km) radius of the Statue of Liberty National Monument.
The Nemi ships were two ships, of different sizes, built under the reign of the Roman emperor Caligula in the 1st century AD on Lake Nemi. Although the purpose of the ships is speculated upon, the larger ship was an elaborate floating palace, which contained quantities of marble, mosaic floors, heating and plumbing, and amenities such as baths. Both ships featured technology thought to have been developed historically later. It has been stated that the emperor was influenced by the lavish lifestyles of the Hellenistic rulers of Syracuse and Ptolemaic Egypt. Recovered from the lake bed in 1929, the ships were destroyed by fire in 1944 during World War II.
The archaeology of shipwrecks is the field of archaeology specialized most commonly in the study and exploration of shipwrecks. Its techniques combine those of archaeology with those of diving to become Underwater archaeology. However, shipwrecks are discovered on what have become terrestrial sites.
Mensun Bound is a British maritime archaeologist born in Stanley, Falkland Islands. He is best known as director of exploration for two expeditions to the Weddell Sea which led to the rediscovery of the Endurance, in which Sir Ernest Shackleton and a crew of 27 men sailed for the Antarctic on the 1914–1917 Imperial Trans-Antarctic Expedition. The ship sank after being crushed by the ice on 21 November 1915. It was rediscovered by the Endurance22 expedition on 5 March 2022.
Mons Claudianus was a Roman quarry in the eastern desert of Egypt. It consisted of a garrison, a quarrying site, and civilian and workers' quarters. Granodiorite was mined for the Roman Empire where it was used as a building material. Mons Claudianus is located in the mountains of the Egyptian Eastern desert about midway between the Red Sea and Qena, in the present day Red Sea Governorate. Today tourists can see fragments of granite, with several artifacts such as a broken column. A number of texts written on broken pottery (ostraca) have been discovered at the site.
The John M. Osborn was a wooden steam barge that sank in Lake Superior in 1884 with the loss of five lives. The Osborn was just 2 years old when the larger, steel-hulled Alberta, which was called a "steel monster" and "terror of the lakes", rammed her. The wreck of the Osborn was discovered 100 years after her sinking. The wreck was illegally salvaged in the 1980s. Many of Osborn's artifacts became the property of the State of Michigan after they were seized from Great Lakes Shipwreck Museum. The State allows the museum to display the artifacts as a loan. The wreck of the Osborn is now protected by the Whitefish Point Underwater Preserve as part of an underwater museum.
The Blackfriars shipwrecks were a series of wrecks discovered by archaeologist Peter Marsden in the Blackfriars area of the banks of the River Thames in London, England. The wrecks were discovered while building a riverside embankment wall along the River Thames. Marsden discovered the first on 6 September 1962 and the next two were discovered in 1970. A later discovery added to the previous three wrecks, constituting now what is known as the four Blackfriars wrecks.
In Imperial Rome, Cura Annonae was the import and distribution of grain to the residents of the cities of Rome and, after its foundation, Constantinople. The term was used in honour of the goddess Annona. The city of Rome imported all the grain consumed by its population, estimated to number 1,000,000 by the 2nd century AD. This included recipients of the grain dole or corn dole, a government program which gave out subsidized grain, then free grain, and later bread, to about 200,000 of Rome's adult male citizens. Rome's grain subsidies were originally ad hoc emergency measures taken to import cheap grain from trading partners and allies at times of scarcity, to help feed growing numbers of indebted and dispossessed citizen-farmers. By the end of the Republic, grain subsidies and doles had become permanent, uniquely Roman institutions. The grain dole was reluctantly adopted by Augustus and later emperors as a free monthly issue to those who qualified to receive it. In 22 AD, Augustus' successor Tiberius publicly acknowledged the Cura Annonae as a personal and imperial duty, which if neglected would cause "the utter ruin of the state".
Gunilda was a steel-hulled Scottish-built steam yacht in service between her construction in 1897 and her sinking in Lake Superior in 1911. Built in 1897 in Leith, Scotland by Ramage & Ferguson for J. M. or A. R. & J. M. Sladen, and became owned by F. W. Sykes in 1898; her first and second owners were all from England. In 1901, Gunilda was chartered by a member of the New York Yacht Club, sailing across the Atlantic Ocean with a complement of 25 crewmen. In 1903, she was purchased by oil baron William L. Harkness of Cleveland, Ohio, a member of the New York Yacht Club; she ended up becoming the club's flagship. Under Harkness' ownership, Gunilda visited many parts of the world, including the Caribbean, and beginning in 1910, the Great Lakes.
115 was an American whaleback barge in service between 1891 and 1899. She was built between May and August 1891, in Superior, Wisconsin by Alexander McDougall's American Steel Barge Company, for the "McDougall fleet", based in Buffalo, New York. She was one of a class of distinctive, experimental ship designed and built by McDougall. The whalebacks were designed to be more stable in high seas. They had rounded decks, and lacked the normal straight sides seen on traditional lake freighters. 115 entered service on August 25, hauling iron ore from Superior.
Ancient Rome had a variety of ships that played crucial roles in its military, trade, and transportation activities. Rome was preceded in the use of the sea by other ancient, seafaring civilizations of the Mediterranean. The galley was a long, narrow, highly maneuverable ship powered by oarsmen, sometimes stacked in multiple levels such as biremes or triremes, and many of which also had sails. Initial efforts of the Romans to construct a war fleet were based on copies of Carthaginian warships. In the Punic wars in the mid-third century BCE, the Romans were at first outclassed by Carthage at sea, but by 256 BCE had drawn even and fought the wars to a stalemate. In 55 BCE Julius Caesar used warships and transport ships to invade Britain. Numerous types of transport ships were used to carry foodstuffs or other trade goods around the Mediterranean, many of which did double duty and were pressed into service as warships or troop transports in time of war.
