Cleat (nautical)
In nautical contexts, a cleat is a device for securing a rope. Types Types of cleat designs include the following: * A horn cleat is the traditional design, featuring two “horns” extending parallel to the deck or the axis of the spar (sailing), spar, attached to a flat surface or a spar, and resembling an anvil. * A cam cleat in which one or two spring-loaded cams pinch the rope, allowing the rope to be adjusted easily, and quickly released when under load. * A jam cleat in which the line is pinched in a v-shaped slot. * A clam cleat (or jam cleat) in which the rope is held between two fluted stationary pieces. Such a cleat vaguely resembles two halves of a clam shell held back to back. It is more compact than a cam cleat, but the rope is less easily released under load. A cleat hitch is a knot used to secure a rope to a cleat. Tied cleat.jpg, A line tied with a cleat hitch to a horn cleatAshley 1993, p. 286. on a dock.

Rope
A rope is a group of yarns, plies, fibres, or strands that are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material, but generally is constructed of certain natural or synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. ...

Spar (sailing)
A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole. In larger vessels during the age of sail, spare spars could be roped together to provide a temporary surface known as a "spar deck". These served as jury-rigged repairs for permanent decks, or as an additional platform under which to shelter goods or crew. The term was also informally applied to areas of the forecastle or quarterdeck where spare spars were stored by laying them flat against the existing decking. In the modern era the term has been used to describe the uppermost deck on flush deck Flush deck is a term in naval architecture. It can refer to any deck of a ship which is continuous from stem to stern. History The flush deck design originated with rice ships built ...

Anvil
An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another object is struck (or "worked"). Anvils are as massive as practical, because the higher their inertia, the more efficiently they cause the energy of striking tools to be transferred to the work piece. In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was the primary tool of metal workers. The great majority of modern anvils are made of cast steel that has been heat treated by either flame or electric induction. Inexpensive anvils have been made of cast iron and low quality steel, but are considered unsuitable for serious use as they deform and lack rebound when struck. Structure The primary work surface of the anvil is known as the face. It is generally made of hardened steel and should be flat and smooth with rounded edges for most work. Any marks on the face will b ...

Hitch Knot
A hitch knot is a type of knot used to secure a rope to an object or another rope. It is used in a variety of situations, including climbing, sailing, and securing loads. Hitch knots are classified based on their ability to be tightened or released, their resistance to slipping, and their strength. Some common types of hitch knots include the fisherman's knot, the water knot, and the clove hitch. Hitch knots are important because they allow a rope to be securely fastened to an object, enabling the rope to support weight or transmit force. Physical theory of hitches A simple mathematical theory of hitches has been proposed by Bayman and extended by Maddocks and Keller. It makes predictions that are approximately correct when tested empirically. Alphabetical list of hitch knots See also * List of knots * Single hitch A turn is one round of rope on a pin or cleat, or one round of a coil. Turns can be made around various objects, through rings, or around the standing part o ...
