The vessel will now swing in the middle of two anchors, which is acceptable in strong reversing currents, but a wind perpendicular to the current may break out the anchors, as they are not aligned for this load. Also known as ""tandem anchoring"", in this technique two anchors are deployed in line with each other, on the same rode. With the foremost anchor reducing"
"by the heraldic terms ""anchry"" or ""ancre"". Anchor An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ""ancora"", which itself comes from the Greek ἄγκυρα (""ankura""). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs"

The heaviest cargo ships may require more than a dozen mooring lines. Small vessels can generally be moored by four to six mooring lines. Mooring lines are usually made from manila rope or a synthetic material such as nylon. Nylon is easy to work with and lasts for years, but it is highly elastic. This elasticity has advantages and disadvantages. The main advantage is that during an event, such as a high wind or the close passing"
"Bitts Bitts are paired vertical wooden or iron posts mounted either aboard a ship or on a wharf, pier or quay. The posts are used to secure mooring lines, ropes, hawsers, or cables. Bitts aboard wooden sailing ships (sometime called cable-bitts) were large vertical timbers mortised into the keel and used as the anchor cable attachment point. Bitts are carefully manufactured and maintained to avoid any sharp edges which might chafe and weaken the mooring lines. Mooring lines may be laid around the bitts either singly or in a figure-8 pattern with the friction against tension increasing with each successive"
"Mooring (watercraft) A mooring refers to any permanent structure to which a vessel may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An ""anchor mooring"" fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, ""mooring"" refers to the act of attaching a vessel to a mooring. The term likely stems from the Dutch verb ""meren"" (to ""moor""), used in English since the end of"

"When at anchor, the anchor rope (called a cable or catfall) was secured to this with a smaller rope tie called a seizing. The English term for this pin was 'Norman'. In German, however, it was called a ""Kattenkopf"" (cat-head), and in this case it is a reference to the traditional way the top was notched and chamfered off so that in cross section, it resembled the ears of a cat. Cathead A cathead is a large wooden beam located on either side of the bow of a sailing ship, and angled forward at roughly 45 degrees. The beam is"
"Chains (nautical) The chains were small platforms, built on either side of the hull of a ship, used to provide a wide purchase for the shrouds, and to assist in the practice of depth sounding. The chains provided a platform for a 'leadsman', the sailor assigned to swing the sounding line, or 'lead' into the water. The term originated from the practice of the sailor standing between the shrouds when casting the line, which were attached to the hull by chainplates, or, in earlier sailing ships, to lengths of chain along the ship's side. A length of chain was usually"

Mooring is often accomplished using thick ropes called ""mooring lines"" or ""hawsers"". The lines are fixed to deck fittings on the vessel at one end and to fittings such as bollards, rings, and cleats on the other end. Mooring requires cooperation between people on a pier and on a vessel. Heavy mooring lines are often passed from larger vessels to people on a mooring by smaller, weighted heaving lines. Once a mooring line is"
"developed for use in safety-critical applications. The bowline's name has an earlier meaning, dating to the age of sail. On a square-rigged ship, a bowline (sometimes spelled as two words, ""bow line"") is a rope that holds the edge of a square sail towards the bow of the ship and into the wind, preventing it from being taken aback. A ship is said to be on a ""taut bowline"" when these lines are made as taut as possible in order to sail close-hauled to the wind. The bowline knot is thought to have been first mentioned in John Smith's 1691"
"Jackline A jackline is a rope or wire strung from a ship's bow to stern to which a safety harness can be clipped, allowing a crewmember to move about the deck safely when there is risk of falling or being swept overboard. At sea, falling overboard is one of the leading causes of death in boating; fastening oneself to the ship with a safety harness reduces this risk. Generally the jacklines are run from the bow to the stern on both starboard and the port side of a ship. Jack lines are used in heavy weather and in periods of"

Some ships use wire rope for one or more of their mooring lines. Wire rope is hard to handle and maintain. There is also risk associated with using wire rope on a ship's stern in the vicinity of its propeller. Mooring lines and hawsers may also be made by combining wire rope and synthetic line. Such lines are more elastic and easier to handle than wire rope, but they are not as elastic"

Anchors are sometimes fitted with a tripping line attached to the crown, by which they can be unhooked from rocks or coral. The term ""aweigh"" describes an anchor when it is hanging on the rope and is not resting on the bottom. This is linked to the term ""to weigh anchor"", meaning to lift the anchor from the sea bed, allowing the ship or boat to"

Early cable ferries often used either rope or steel chains, with the latter resulting in the alternate name of chain ferry. Both of these were largely replaced by wire cable by the late 19th century. There are"

Largely replaced on most modern vessels by cleats, they are still used, particularly on square rigged ships. A belaying pin is composed of a round handle and cylindrical shaft. The shaft is inserted into a hole in various strategically located wooden ""pinrails"" (lining the inside of the bulwarks, surrounding the base of masts, or free-standing, called fife rails) up to the base of the handle. A line is then led under and behind the base of"

In some harbours (e.g. Dun Laoghaire, Ireland), very heavy chain (e.g. old ship anchor chain) may be placed in a grid pattern on the sea bed to ensure orderly positioning of moorings. Ropes (particularly for marker buoys and messenger lines) should be ""non floating"" to reduce likelihood of a boat's prop being fouled by one.
