A rib is a bone attached to the spine, in vertebrate animals.
Rib, ribs or RIB may also refer to:
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top, or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.
A kayak is a small, narrow human-powered watercraft typically propelled by means of a long, double-bladed paddle. The word kayak originates from the Inuktitut word qajaq. In British English, the kayak is also considered to be a kind of canoe.
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina.
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium, and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space habitats employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, blowing, and suction.
A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along the boat's topsides. The design is stable, light, fast and seaworthy. The inflated collar acts as a life jacket, ensuring that the vessel retains its buoyancy, even if the boat is taking on water. The RIB is an evolutionary development of the inflatable boat with a rubberized fabric bottom that is stiffened with flat boards within the collar to form the deck or floor of the boat.
An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas. For smaller boats, the floor and hull are often flexible, while for boats longer than 3 metres (9.8 ft), the floor typically consists of three to five rigid plywood or aluminium sheets fixed between the tubes, but not joined rigidly together. Often the transom is rigid, providing a location and structure for mounting an outboard motor.
Boat building is the design and construction of boats — and their on-board systems. This includes at minimum the construction of a hull, with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
A rib vault or ribbed vault is an architectural feature for covering a wide space, such as a church nave, composed of a framework of crossed or diagonal arched ribs. Variations were used in Roman architecture, Byzantine architecture, Islamic architecture, Romanesque architecture, and especially Gothic architecture. Thin stone panels fill the space between the ribs. This greatly reduced the weight and thus the outward thrust of the vault. The ribs transmit the load downward and outward to specific points, usually rows of columns or piers. This feature allowed architects of Gothic cathedrals to make higher and thinner walls and much larger windows.
World Coming Down is the fifth studio album by the American gothic metal band Type O Negative. Released on September 21, 1999, it is considered to be the darkest of the band's releases, having been written after a series of deaths in frontman Peter Steele's family, combined with the desire to break away from the sexually charged themes of the previous albums. It was also the band's first album to reach the Top 40 on the Billboard 200.
The flexi disc is a phonograph record made of a thin, flexible vinyl sheet with a molded-in spiral stylus groove, and is designed to be playable on a normal phonograph turntable.

The D-class (EA16) lifeboat is a class of inflatable boat operated since 1987 by the Royal National Lifeboat Institution of the United Kingdom and Ireland. It has been replaced operationally by the D-class (IB1), but many are still used as part of the relief fleet, as boarding boats for the larger classes of lifeboat and by the RNLI Flood Rescue Team.
In mechanical engineering, stressed skin is a rigid construction in which the skin or covering takes a portion of the structural load, intermediate between monocoque, in which the skin assumes all or most of the load, and a rigid frame, which has a non-loaded covering. Typically, the main frame has a rectangular structure and is triangulated by the covering; a stressed skin structure has localized compression-taking elements and distributed tension-taking elements (skin).
The Lioré et Olivier LeO H.242 was a monoplane flying boat aircraft designed and produced by the French aircraft manufacturer Lioré et Olivier. It was used for European passenger air services in the 1930s, including by the flag carrier Air France. One LeO H.242 was depicted near the end of Hergé's The Adventures of Tintin comic King Ottokar's Sceptre.
A rescue lifeboat is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, inflatable or rigid-inflatable combination-hulled vessels.
The Manchester Unity of Oddfellows was an Oakley-class lifeboat of the Royal National Lifeboat Institution (RNLI) stationed at Sheringham in the English county of Norfolk from 10 July 1961 until 1990 when she was replaced after 29 years service by an Atlantic 75 second generation Rigid Inflatable Boat (RIB) in May 1992. During the time that The Manchester Unity of Oddfellows was on station at Sheringham, she performed 127 service launches, rescuing 134 lives.
Mudeford Lifeboat Station is the base for Royal National Lifeboat Institution (RNLI) search and rescue operations at Mudeford, Christchurch, Dorset in England. The first lifeboat was stationed on Mudeford Quay 1963 and the present station was opened in 2003. It operates an Atlantic 85 inshore lifeboat (ILB).
The D-class lifeboat was a sub-class of 4 inflatable boats operated as part of the D-class between 1971 and 1986 by the Royal National Lifeboat Institution of the United Kingdom and Ireland. It was superseded by the D-class lifeboat.
Zodiac Milpro, headquartered in Paris, France, is a company that manufactures inflatable boats and rigid hull inflatable boats for the emergency services, military and professional users, including heavy-duty inflatable work boats that can carry payloads up to four tons and passengers for ecotourism, whale watching, etc.
A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown meet at an angle at the top of the arch. Also known as a two-centred arch, its form is derived from the intersection of two circles. This architectural element was particularly important in Gothic architecture. The earliest use of a pointed arch dates back to bronze-age Nippur. As a structural feature, it was first used in eastern Christian architecture, Byzantine architecture and Sasanian architecture, but in the 12th century it came into use in France and England as an important structural element, in combination with other elements, such as the rib vault and later the flying buttress. These allowed the construction of cathedrals, palaces and other buildings with dramatically greater height and larger windows which filled them with light.
