Cattewater Wreck
Cattewater Wreck is a wooden three-masted, skeleton-built vessel, one of many ships that have wrecked in Cattewater, Plymouth Sound, England. This wreck is close to the entrance of Sutton Harbour, its name is still unknown but it is believed to be from the 16th Century. It is a Protected Wreck managed by Historic England. History The wreck was found in 1973 when a dredger being used to deepen the Cattewater brought up timber wreckage and parts of some iron guns. An underwater investigation of the site in 1973 was instigated by the National Maritime Museum and the Department for the Environment. The investigation produced a provisional site plan and included the more controlled recovery of loose wreckage including concreted fragments of an iron muzzle loading cannon. The hull structure was the lowest section of hull from one end past the midships area, where the dredging work had caused extensive damage. Based on the assessments the site was recommended for designation under t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cattewater
The city of Plymouth, Devon, England is bounded by Dartmoor to the north, the Hamoaze to the west, the open expanse of water called Plymouth Sound to the south and the river Plym to the east. The Cattewater is that stretch of water where the mouth of the river Plym merges with Plymouth Sound, just to the east of Sutton Pool. It is around this Pool that the manor of Sutton started, which grew to form the present day city. On the northern shore of this confluence of waters there was a rock outcrop, which it was claimed, had the appearance of a cat.compare the similarly named Kattegat which ultimately derives from Old Dutch, the common North European language of Mediaeval mariners This gave its name to this stretch of water and eventually the name of Cattedown to the adjoining wharves and commercial area. Apart from an occasional small oil tanker the area is now used mostly by fishing trawlers, yachts, and smaller pleasure craft. There is a water taxi across it from the Mayflower ...

Plymouth Sound
Plymouth Sound, or locally just The Sound, is a deep inlet or sound in the English Channel near Plymouth in England. Description Its southwest and southeast corners are Penlee Point in Cornwall and Wembury Point in Devon, a distance of about 3 nautical miles (6 km). Its northern limit is Plymouth Hoe giving a north–south distance of nearly 3 nautical miles (6 km). The Sound has three water entrances. The marine entrance is from the English Channel to the south, with a deep-water channel to the west of the Plymouth Breakwater. There are two freshwater inlets: one, from the northwest, is from the River Tamar via the Hamoaze and Devonport Dockyard, the largest naval dockyard in western Europe. The other, at northeast, is from the River Plym disgorging into its narrow estuary, Cattewater harbour between Mount Batten and the Royal Citadel. In the centre of the Sound, midway between Bovisand Bay and Cawsand Bay, is Plymouth Breakwater, which creates a har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Wrecks Of The UK
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Historic England
Historic England (officially the Historic Buildings and Monuments Commission for England) is an executive non-departmental public body of the British Government sponsored by the Department for Digital, Culture, Media and Sport. It is tasked with protecting the historic environment of England by preserving and listing historic buildings, scheduling ancient monuments, registering historic Parks and Gardens and by advising central and local government. The body was officially created by the National Heritage Act 1983, and operated from April 1984 to April 2015 under the name of English Heritage. In 2015, following the changes to English Heritage's structure that moved the protection of the National Heritage Collection into the voluntary sector in the English Heritage Trust, the body that remained was rebranded as Historic England. The body also inherited the Historic England Archive from the old English Heritage, and projects linked to the archive such as Britain from Above ...

Protection Of Wrecks Act 1973
The Protection of Wrecks Act 1973 (c. 33) is an Act of the Parliament of the United Kingdom which provides protection for designated shipwrecks. Section 1 of the act provides for wrecks to be designated because of historical, archaeological or artistic value. Section 2 provides for designation of dangerous sites. Wreck sites must have a known location in order to be designated. Designated wrecks are marked on admiralty charts and their physical location is sometimes marked by means of a buoy (sea mark). Information boards are often provided at nearby launch points on land. Wrecks designated by virtue of historical, archaeological or artistic value It is a criminal offence to interfere with a wreck designated under section 1 of the act without a licence. Navigation, angling and bathing are permitted provided this will not interfere with the wreck. A licence is required to dive at the wreck site. Separate licences are required for any disturbance, such as recovery of artifacts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in feet, from the stem to the sternpost; * '' Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capacity in cubic feet, another method of volumetric measurem ...

Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The first magnetometer capable of measuring the absolute magnetic intensity at a point in space was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall effect, which is still widely used. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.

Site Recorder
Site Recorder is a geographical information system (GIS) and information management system (IMS) designed for use in maritime, freshwater and intertidal archaeology. Site Recorder can be used on maritime and intertidal archaeology projects for real-time data collection, decision support, publication, archiving and data migration. The program is designed for use by archaeologists rather than GIS experts. Site Recorder can replace the many separate surveying, drawing, finds handing and reporting programs usually used on site. Site plans can be drawn that connect the positions of finds drawn on the plan with the positions of survey points, so the plans adapt and improve as more survey and recording data is added. Site Recorder can be used for all phases of an archaeological project: * Excavation recording * Site assessment and monitoring * Survey planning and recording * Publication and reporting * Reprocessing existing site data * Resource evaluation and management * Archiving * ...

Archaeology Of Shipwrecks
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. It is necessary to understand the processes and theories by which a wreck site is formed to take into account the distortions in the archaeological material caused by the filtering and scrambling of material remains that occurs during and after the wrecking process. Prior to being wrecked, the ship would have operated as an organised machine, and its crew, equipment, passengers and cargo need to be considered as a system. The material remains should provide clues to the functions of seaworthiness, navigation and propulsion as well as to ship-board life. These clues can also infer how a ship functioned, in special regards to social, political, and economic systems. These underwater s ...

Sailing Ships
A sailing ship is a sea-going vessel that uses sails mounted on masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing square-rigged or fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship, said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast, for instance some schooners. Still others employ a combination of square and fore-and-aft sails, including the barque, barquentine, and brigantine. Early sailing ships were used for river and coastal waters in Ancient Egypt and the Mediterranean. The Austronesian peoples developed maritime technologies that included the fore-and-aft crab-claw sail and with catamaran and outrigger hull configurations, which enabled the Austronesian expansion into the islands of the Indo-Pacific. This expansion originated in Taiwan BC and propagated through Island Southeast Asi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth, Devon
Plymouth () is a port city and unitary authority in South West England. It is located on the south coast of Devon, approximately south-west of Exeter and south-west of London. It is bordered by Cornwall to the west and south-west. Plymouth's early history extends to the Bronze Age when a first settlement emerged at Mount Batten. This settlement continued as a trading post for the Roman Empire, until it was surpassed by the more prosperous village of Sutton founded in the ninth century, now called Plymouth. In 1588, an English fleet based in Plymouth intercepted and defeated the Spanish Armada. In 1620, the Pilgrim Fathers departed Plymouth for the New World and established Plymouth Colony, the second English settlement in what is now the United States of America. During the English Civil War, the town was held by the Parliamentarians and was besieged between 1642 and 1646. Throughout the Industrial Revolution, Plymouth grew as a commercial shipping port, handling imports an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
