Contessa 32
The Contessa 32 is a 9.75 metre (32 ft) fibreglass monohull sailing yacht, designed in 1970 by David Sadler in collaboration with yachtbuilder Jeremy Rogers, as a larger alternative to the Contessa 26. With over 750 hulls built, the yacht has become the most successful one-design cruiser-racer of all time. The yachts have a masthead sloop rig, with a fin keel and a skeg-mounted rudder, a cutting edge concept for the period which now represents a cross between newer and older designs. The Contessa 32 is seaworthy enough for offshore voyages in extreme weather conditions, but also performs well in races, and as a one-design racing class is administered by an active Association. The trait most often associated with the Contessa 32 though is its ability to endure harsh weather and rough seas. A Contessa 32 was the only yacht in the small boat class to finish the disastrous 1979 Fastnet race, in which 15 people died. Production by the Jeremy Rogers boatyard ceased in 1982, t ...

Monohull
image:monohull.svg, right A monohull is a type of boat having only one hull (watercraft), hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or Sailing ballast, ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Ancient Rome, Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stabil ...

Jeremy Rogers Limited
Jeremy Rogers Ltd. is a British boatyard based in Lymington. Founded by English boatbuilder and sailor Jeremy Rogers in 1961, it is currently known for construction to order of the classic Contessa 32 design, and refurbishment of Contessa and other yachts. The yard is notable for the high quality handbuilding of the yachts, and the renowned seaworthiness of the designs compared to modern mass-production yards. History The business was founded by Rogers in 1961, and by the early 1980s was employing 200 people in five factories in Lymington building the Contessa 26, Contessa 32 and the Doug Peterson designed Grand Prix 35s, 39s and 43s, and exporting the yachts worldwide. Although an insolvency forced production to stop, in 1995 the Contessa 32 moulds were bought back and production on a bespoke basis restarted. The yard currently offers refurbishment and parts support for Contessa yachts, as well as refitting of other yacht makes. A 'Green' Contessa 2011, the 40th Anniversary ...

U-bolt
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends. U-bolts have primarily been used to support pipework Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. Industrial process piping (and accompan ..., pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting. U-bolts are also used to hold ropes together. For example, a 40 Nominal Bore U-bolt would be asked for by pipe work engineers, and only they would know what that meant. In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt. The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balsa
''Ochroma pyramidale'', commonly known as the balsa tree, is a large, fast-growing tree native to the Americas. It is the sole member of the genus ''Ochroma''. The tree is famous for its wide usage in woodworking, with the name ''balsa'' being the Spanish word for "raft." A deciduous angiosperm, ''Ochroma pyramidale'' can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight.

Glassfibre
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Capsizing
Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, , loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast. If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not stable inverted. Vessels of this design are called self-righting. Small vessels In dinghy sailing, a practical distinction can be made between being knocked down (to 90 degrees; on its beam-ends, figuratively) which is called a capsize, and being inverted, which is called being turtled. Small dinghies frequently capsize in the normal course of use and can usually be recovered by the crew. Some types of dinghy are occasi ...

Limit Of Positive Stability
In sailing, the limit of positive stability (LPS) or angle of vanishing stability (AVS) is the angle from the vertical at which a boat will no longer stay upright but will capsize, becoming :wikt:inverted, inverted, or Turtling (sailing), turtled. For example, if a boat with an LPS of 120 Degree (angle), degrees rolls past this point, i.e. its Mast (sailing), mast is already at an angle of 30 degrees below the water, it will continue to roll and be completely upside down in the water. Except for Dinghy sailing, dinghy sailboats and multihulls, most larger sailboats (monohull keelboats) have lead or other heavy materials in their keel at the bottom of their hulls to keep them from capsizing or turtling. The LPS was a part of the Offshore Racing Rules and is used to measure how Ship stability, stable or seaworthy a sailboat is. The modern offshore racing rules published by the International Sailing Federation may also use the measurement. See also *Angle of loll *Capsizing * ...

Cutter (ship)
A cutter is a type of watercraft. The term has several meanings. It can apply to the rig (or sailplan A sail plan is a description of the specific ways that a sailing craft is rigged. Also, the term "sail plan" is a graphic depiction of the arrangement of the sails for a given sailing craft.> In the English language, ships were usually describe ...) of a sailing vessel (but with regional differences in definition), to a governmental enforcement agency vessel (such as a coast guard or border force cutter), to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships. As a sailing rig, a cutter is a single-masted boat, with two or more headsails. On the eastern side of the Atlantic Ocean, Atlantic, the two headsails on a single mast is the fullest extent of the modern definition. In U.S. waters, a greater level of complexity applies, with the placemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Sailing Ballast
Ballast is used in ships to provide moment to resist the lateral forces on the hull. Insufficiently ballasted boats tend to tip or heel excessively in high winds. Too much heel may result in the vessel capsizing. If a sailing vessel needs to voyage without cargo, then ballast of little or no value will be loaded to keep the vessel upright. Some or all of this ballast will then be discarded when cargo is loaded. Uses Ballast takes many forms. The simplest form of ballast used in small day sailers is so-called "live ballast", or the weight of the crew. By sitting on the windward side of the hull, the heeling moment must lift the weight of the crew. On more advanced racing boats, a wire harness called a trapeze is used to allow the crew to hang completely over the side of the hull without falling out; this provides much larger amounts of righting moment due to the larger leverage of the crew's weight, but can be dangerous if the wind suddenly dies, as the sudden loss of heeling ...
