A crow's nest is a structure in the upper part of the main mast of a ship or a structure that is used as a lookout point. On ships, this position ensured the widest field of view for lookouts to spot approaching hazards, other ships, or land by using the naked eye or optical devices such as telescopes or binoculars. It should not be confused with the top, the platform in the upper part of each lower mast of a square-rigged sailing ship.
The form of crow's nest used by the ancient Greeks and Romans was the carchesium (Ancient Greek : καρχήσιον , karkhḗsion), named after a supposed similarity to a kind of ritual wine goblet.
According to William Scoresby Jr., the crow's nest was invented in the 19th century by his father, William Scoresby Sr., a whaler and also an Arctic explorer. [1] However, Scoresby Sr. may simply have made an improvement on existing designs. [2] Crow's nests appear in Egyptian reliefs as early as 1200 BC and on eighth to seventh century BC representations of Phoenician, Etruscan, and Boiotian ships. [3] The crow’s nest disappears completely from depictions of ships after the seventh century, although the relationship between a raised vantage point and better visibility continued to be well understood. Theon of Smyrna wrote that by climbing the mast of a ship, one could see land that is invisible to those on deck. [3]
The first recorded appearance of the term was in 1807, used to describe Scoresby Sr.'s barrel crows nest platform.[ citation needed ] According to a popular naval legend, the term derives from the practice of Viking sailors, who carried crows or ravens in a cage secured to the top of the mast. In cases of poor visibility, a crow was released, and the navigator plotted a course corresponding to the bird's flight path because the bird invariably headed "as the crow flies" towards the nearest land. [4] However, other naval scholars have found no evidence of the masthead crow cage and suggest the name was coined because Scoresby's lookout platform resembled a crow's nest in a tree. [5]
Since the crow's nest is a point far away from the ship's center of mass, rotational movement of the ship is amplified and could lead to severe seasickness, even in accustomed sailors. Therefore, being sent to the crow's nest was also considered a punishment.[ citation needed ]
In classic railroad trains, the box-like structure above the caboose, the cupola, was also called the crow's nest. It served for observation of the whole train when in motion. [6]
In hunting, a crow's nest is a blind-like structure where a hunter or a pair of hunters commit themselves to stalking game. A crow's nest is not a normal type of purchasable blind, but an improvised position, built by using locally discovered natural flora (tree branches, moss, snow (during winter) or sand (during summer), etc.). A crow's nest works in most environments and provides a good lookout point (hence the name) when built in an elevated position like a hillside or top of a hill.
The term is sometimes used metaphorically for the topmost structures in buildings, towers, etc. Such structures are often referred to as a Widow's walk.
A trireme was an ancient vessel and a type of galley that was used by the ancient maritime civilizations of the Mediterranean Sea, especially the Phoenicians, ancient Greeks and Romans.
A broadside is the side of a ship, or more specifically the battery of cannon on one side of a warship or their coordinated fire in naval warfare, or a measurement of a warship's maximum simultaneous firepower which can be delivered upon a single target. From the 16th century until the early decades of the steamship, vessels had rows of guns set in each side of the hull. Firing all guns on one side of the ship became known as a "broadside". The cannon of 18th-century men of war were accurate only at short range, and their penetrating power mediocre, which meant that the thick hulls of wooden ships could only be pierced at short ranges. These wooden ships sailed closer and closer towards each other until cannon fire would be effective. Each tried to be the first to fire a broadside, often giving one party a decisive headstart in the battle when it crippled the other ship.
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 afterend. Often rudders are shaped 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 link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
The Royal Canadian Navy is the naval force of Canada. The navy is one of three environmental commands within the Canadian Armed Forces. As of February 2024, the RCN operates 12 Halifax-class frigates, 12 Kingston-class coastal defence vessels, 4 Victoria-class submarines, 4 Harry DeWolf-class offshore patrol vessels, 8 Orca-class patrol vessels, and several auxiliary vessels. The RCN consists of 8,400 Regular Force and 4,100 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the commander of the Royal Canadian Navy and chief of the Naval Staff.
The expression as the crow flies is an idiom for the most direct path between two points.
William Scoresby was an English whaler, Arctic explorer, scientist and clergyman.
The forecastle is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase "before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers.
Smeerenburg was a whaling settlement on Amsterdam Island in northwest Svalbard. It was founded by the Danish and Dutch in 1619 as one of Europe's northernmost outposts. With the local bowhead whale population soon decimated and whaling developed into a pelagic industry, Smeerenburg was abandoned around 1660.
A bomb vessel, bomb ship, bomb ketch, or simply bomb was a type of wooden sailing naval ship. Its primary armament was not cannons – although bomb vessels carried a few cannons for self-defence – but mortars mounted forward near the bow and elevated to a high angle, and projecting their fire in a ballistic arc. Explosive shells or carcasses were employed rather than solid shot. Bomb vessels were specialized ships designed for bombarding fixed positions on land. In the 20th century, this naval gunfire support role was carried out by the most similar purpose-built World War I- and II-era monitors, but also by other warships now firing long-range explosive shells.
Crows Nest, Crow's Nest or Crowsnest may refer to:
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed.
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water. Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".
The quarterdeck is a raised deck behind the main mast of a sailing ship. Traditionally it was where the captain commanded his vessel and where the ship's colours were kept. This led to its use as the main ceremonial and reception area on board, and the word is still used to refer to such an area on a ship or even in naval establishments on land. Many such facilities have areas decorated like shipboard quarterdecks.
A galley is a type of ship optimised for propulsion by oars. Galleys were historically used for warfare, trade, and piracy mostly in the seas surrounding Europe. It developed in the Mediterranean world during antiquity and continued to exist in various forms until the early 19th century. It typically had a long, slender hull, shallow draft, and often a low freeboard. Most types of galleys also had sails that could be used in favourable winds, but they relied primarily on oars to move independently of winds and currents or in battle. The term "galley" originated from a Greek term for a small type of galley and came in use in English from about 1300. It has occasionally been used for unrelated vessels with similar military functions as galley but which were not Mediterranean in origin, such as medieval Scandinavian longships, 16th-century Acehnese ghalis and 18th-century North American gunboats.
Barrelman is in reference to a person who would be stationed in the barrel of the foremast or crow's nest of an oceangoing vessel as a navigational aid. In early ships the crow's nest was simply a barrel or a basket lashed to the tallest mast. Later it became a specially designed platform with protective railing.
A lookout or look-out is a person in charge of the observation of hazards. The term originally comes from a naval background, where lookouts would watch for other ships, land, and various dangers. The term has now passed into wider parlance.
His Majesty's Naval Base, Devonport is one of three operating bases in the United Kingdom for the Royal Navy and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest naval base in Western Europe, HMNB Devonport is located in Devonport, in the west of the city of Plymouth, England.
David Blair was a British merchant seaman with the White Star Line, which had reassigned him from the RMS Titanic just before its maiden voyage. Due to his hasty departure, he accidentally kept a key to a storage locker believed to contain the binoculars intended for use by the crow's nest lookout. The absence of any binoculars within the crow's nest is considered by some to be a contributory factor in the Titanic’s ultimate demise.
Fame was launched in India in 1786. She was sold to Portuguese owners. A French privateer captured but the Royal Navy recaptured her in 1794. She then became a West Indiaman, sailing from Liverpool. Between 1796 and 1804 she made three voyages as a slave ship in the triangular trade in enslaved people. She then returned to the West Indies trade. From 1818 on she was a whaler in the Greenland whale fishery, sailing from Whitby and then Hull. She burnt in 1823 while outward bound on a whaling voyage.
