A cringle is an eye through which to pass a rope. In nautical settings, the word refers to a small hole anywhere along the edge or in the corner of a sail, rimmed with stranded cordage and worked into the boltrope. [1] Typically it encloses a metal grommet for reinforcement and to reduce wear. In this context, cringle and grommet coincide enough that the two are sometimes used interchangeably. [2] [3]
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water, on ice (iceboat) or on land over a chosen course, which is often part of a larger plan of navigation.
A barque, barc, or bark is a type of sailing vessel with three or more masts having the fore- and mainmasts rigged square and only the mizzen rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above.
A grommet is a ring or edge strip inserted into a hole through thin material, typically a sheet of textile fabric, sheet metal or composite of carbon fiber, wood or honeycomb. Grommets are generally flared or collared on each side to keep them in place, and are often made of metal, plastic, or rubber. They may be used to prevent tearing or abrasion of the pierced material or protection from abrasion of the insulation on the wire, cable, line being routed through the penetration, and to cover sharp edges of the piercing, or all of the above.
In sailing, a cunningham or cunningham's eye is a type of downhaul used on a Bermuda rigged sailboat to change the shape of a sail. It is named after its inventor, Briggs Cunningham, a victorious America's Cup skipper and yacht builder.
A tarpaulin, or tarp, is a large sheet of strong, flexible, water-resistant or waterproof material, often cloth such as canvas or polyester coated with polyurethane, or made of plastics such as polyethylene. In some places such as Australia, and in military slang, a tarp may be known as a hootch. Tarpaulins often have reinforced grommets at the corners and along the sides to form attachment points for rope, allowing them to be tied down or suspended.
Running rigging is the rigging of a sailing vessel that is used for raising, lowering, shaping and controlling the sails on a sailing vessel—as opposed to the standing rigging, which supports the mast and bowsprit. Running rigging varies between vessels that are rigged fore and aft and those that are square-rigged.
The Optimist, also known as the ‘opti’, 'oppie', or 'bathtub' is a small, single-handed sailing dinghy intended for use by children up to the age of 15. Contemporary boats are usually made of fibreglass, although wooden boats are still built.
A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of mast and rigging for a type of sailboat and is the typical configuration for most modern sailboats. This configuration was developed in Bermuda in the 17th century; the term Marconi, a reference to the inventor of the radio, Guglielmo Marconi, became associated with this configuration in the early 20th century because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts.
Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel and its shape,. Sails are typically constructed out of flexible material that is shaped by various means, while in use, to offer an appropriate airfoil, according to the strength and apparent direction of the wind. A variety of features and fittings allow the sail to be attached to lines and spars.
The International Contender is a single-handed high performance sailing dinghy, designed by Bob Miller, latterly known as Ben Lexcen, (Australia) in 1967 as a possible successor to the Finn dinghy for Olympic competition.
Reefing is the means of reducing the area of a sail, usually by folding or rolling one edge of the canvas in on itself. The converse operation, removing the reef, is called "shaking it out." Reefing improves the performance of sailing vessels in strong winds, and is the primary safety precaution in rough weather. Reefing sails improves vessel stability and minimizes the risk of damage to the sail or other gear. Proper skills in and equipment for reefing are crucial to averting the dangers of capsizing or broaching in heavy weather.
Tympanostomy tube, also known as a grommet or myringotomy tube, is a small tube inserted into the eardrum in order to keep the middle ear aerated for a prolonged period of time, and to prevent the accumulation of fluid in the middle ear. The operation to insert the tube involves a myringotomy and is performed under local or general anesthesia. The tube itself is made in a variety of designs. The most commonly used type is shaped like a grommet. When it is necessary to keep the middle ear ventilated for a very long period, a "T"-shaped tube may be used, as these "T-tubes" can stay in place for 2–4 years. Materials used to construct the tube are most often plastics such as silicone or Teflon. Stainless steel tubes exist, but are no longer in frequent use.
An outhaul is a line which is part of the running rigging of a sailboat, used to extend a sail and control the shape of the curve of the foot of the sail. It runs from the clew to the end of the boom. The line is pulled taut to the appropriate tension to provide the desired shape to the foot and then secured to a cleat on the boom.
Cringle Moor, at 432 m (1,417 ft), is the third highest hill in the North York Moors, England, and the highest point west of Clay Bank.
Polytarp sails refer to sails constructed from rectangular polyethylene tarpaulins. Home boat builders often favor these synthetic sheet sails because the materials are inexpensive and easy to assemble into functional, durable sails.
A haversack or small pack is a bag with a single shoulder strap. Although similar to a backpack, the single shoulder strap differentiates this type from other backpacks. There are exceptions to this general rule.
USNS Grommet Reefer (T-AF-53) was a Grommet Reefer-class stores ship acquired by the U.S. Navy. Her task was to carry stores, refrigerated items, and equipment to ships in the fleet, and to remote stations and staging areas.
The Pelican is a pram dinghy, peculiar to Perth, Western Australia
A sail is a tensile structure—made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape.
HMPNGS Rabaul (01) was the first Pacific Forum patrol vessel to be commissioned, in May 1987. She is not the first vessel to go out of service, because her sister ship from Fiji RFNS Kiro was wrecked in 2016. She arrived in Port Moresby, for disposal, on October 24, 2018.
