Hull (watercraft)

A hull is the watertight body of a ship or boat. The hull may open at the top, or it may be or 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. There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat; the shape is chosen to strike a balance between cost, hydrostatic considerations and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. In a typical modern steel ship, the hull will have watertight decks, major transverse members called bulkheads. There may be intermediate members such as girders and webs, minor members called ordinary transverse frames, frames, or longitudinals, depending on the structural arrangement.

The uppermost continuous deck may be called the "upper deck", "weather deck", "spar deck", "main deck", or "deck". The particular name given depends on the context—the type of ship or boat, the arrangement, or where it sails. In a typical wooden sailboat, the hull is constructed of wooden planking, supported by transverse frames and bulkheads, which are further tied together by longitudinal stringers or ceiling, but not always there is a centerline longitudinal member called a keel. In fiberglass or composite hulls, the structure may resemble wooden or steel vessels to some extent, or be of a monocoque arrangement. In many cases, composite hulls are built by sandwiching thin fiber-reinforced skins over a lightweight but reasonably rigid core of foam, balsa wood, impregnated paper honeycomb or other material; the earliest proper hulls were built by the Ancient Egyptians, who by 3000 BC knew how to assemble wooden planks into a hull. Hulls come in many varieties and can have composite shape, but are grouped as follows: Chined and hard-chined.

Examples are the flat-bottom, v-bottom, multi-bottom hull. These types have at least one pronounced knuckle throughout most of their length. Moulded, round soft-chined; these hull shapes all have smooth curves. Examples are the round bilge, semi-round bilge, s-bottom hull. Displacement hull: here the hull is supported or predominantly by buoyancy. Vessels that have this type of hull travel through the water at a limited rate, defined by the waterline length, they are though not always, heavier than planing types. Planing hull: here, the planing hull form is configured to develop positive dynamic pressure so that its draft decreases with increasing speed; the dynamic lift reduces the wetted surface and therefore the drag. They are sometimes flat-bottomed, sometimes V-bottomed and more round-bilged; the most common form is to have at least one chine, which makes for more efficient planing and can throw spray down. Planing hulls are more efficient at higher speeds, although they still require more energy to achieve these speeds.

An effective planing hull must be as light as possible with flat surfaces that are consistent with good sea keeping. Sail boats that plane must sail efficiently in displacement mode in light winds. Semi-displacement, or semi-planing: here the hull form is capable of developing a moderate amount of dynamic lift. At present, the most used form is the round bilge hull. In the inverted bell shape of the hull, with a smaller payload the waterline cross-section is less, hence the resistance is less and the speed is higher. With a higher payload the outward bend provides smoother performance in waves; as such, the inverted bell shape is a popular form used with planing hulls. A chined hull consists of straight, tall, long, or short plates, timbers or sheets of ply, which are set at an angle to each other when viewed in transverse section; the traditional chined hull is a simple hull shape because it works with only straight planks bent into a curve. These boards are bent lengthwise. Plywood chined boats made of 8' x 4' sheets have most bend along the long axis of the sheet.

Only thin ply 3–6 mm can be shaped into a compound bend. Most home-made constructed boats are chined hull boats. Mass-produced chine powerboats are made of sprayed chop strand fibreglass over a wooden mold; the Cajun "pirogue" is an example of a craft with hard chines. Benefits of this type of hull is the low production cost and the flat bottom, making the boat faster at planing. Sail boats with chined hull make use of a dagger keel. Chined hulls may have one of three shapes: Flat-bottom chined hulls Multi-chined hulls V-bottom chined hulls. Sometimes called hard chine; each of these chine hulls use. The flat-bottom hull has high initial stability but high drag. To counter the high drag, hull forms are narrow and sometimes tapered at bow and stern; this leads to poor stability. This is countered by using heavy interior ballast on sailing versions, they are best suited to sheltered inshore waters. Early racing power boats were flat aft; this produced maximum lift and a smooth, fast ride in flat water, but this hull form is unsettled in waves.

The multi chine hull approximates a

Francis Webb (engineer)

Francis William Webb was an English railway engineer, responsible for the design and manufacture of locomotives for the London and North Western Railway. Webb was born in Tixall Rectory, near the second son of William Webb, Rector of Tixall. Showing early interest in mechanical engineering, on 11 August 1851 at the age of fifteen he was articled as a pupil of Francis Trevithick at Crewe Works. Webb joined the drawing office at the end of his training, he became Chief Draughtsman on 1 March 1859. On 1 September 1861 he was appointed Works Manager at Chief Assistant to John Ramsbottom. Whilst Works Manager Webb was responsible for the installation of Bessemer converters and the start of steel production at Crewe. In July 1866 Webb moved to the Bolton Iron and Steel Co. as the manager. It has been suggested that this move was arranged by the LNWR management to enable him to gain experience of steel making. Ramsbottom gave 12 months notice of his resignation in September 1870. Shortly afterwards the Works Manager, Thomas Stubbs, died aged 34.

Stubbs may have been Ramsbottom's intended successor. The Chairman of the LNWR, Richard Moon, invited him to return to Crewe. In October 1870 Moon was able to inform Webb that his appointment as Locomotive Superintendent had been approved. Webb's salary was set at £2,000 for the first year, £3,000 for the second and subsequent years. Webb took up his position on 1 October 1871. Webb became Chief Mechanical Engineer, it appears. At the same time he became President of the Crewe Mechanics' Institute, where he had for some time taught engineering drawing during his first stay at Crewe. Webb remained as CME of the LNWR until 1 July 1903, having tendered his resignation in November 1902, his successor, George Whale, was appointed in April 1903. Whale took over Webb's position somewhat earlier than planned, as Webb became ill in June. Webb was responsible throughout his career for some successful standard locomotive classes, all built at Crewe in considerable numbers. Notable amongst these is the Precedent class of 2-4-0, an 0-6-0 general purpose freight design, its 0-6-2 variant, a celebrated 0-6-0 mixed traffic design, an 0-8-0 freight locomotive with two compound variants and a simple expansion version produced in parallel, The last-mentioned was continuously developed and built down to LMS days, most earlier locomotives being rebuilt to conform.

There does however remain some controversy over Webb's own two distinct compound systems applied to a number of locomotive designs, which are reputed to have given considerable trouble in service. The Webb Experiment or Improved Precedent class were withdrawn by his successor George Whale soon after he succeeded Webb in 1903. An obituary in The Engineer criticised his express compound design, which used un-coupled high and low pressure cylinders, a design promoted by Webb alone; the article caused open debate in the pages of the journal based on the perceived flaw of not utilising coupling rods. In the 20 June edition the editor of the journal continued the attack on the deceased engineer, stating: It is a noteworthy fact that no railway authority in Great Britain and Ireland believed in these engines. On what evidence that faith was based we have never been able to discover Webb was responsible for the remodelling of Crewe station which involved the building of four tracks in underpasses on the west side of the station to carry freight trains.

He received over 80 patents. He was Vice-President of the Institution of Civil Engineers and the Institution of Mechanical Engineers. Webb took a great interest in local politics and was an Alderman on the Crewe Town Council and had been Mayor twice, he was an Alderman on Cheshire County Council. In Crewe he was for many years remembered as a major benefactor of the "Webb Orphanage", a beautiful red-brick building with extensive playing fields behind the railway works and fronting on Victoria Avenue. Together with Richard Moon, Chairman of the LNWR, he presented, to the Crewe Corporation, on behalf of the railway company, Queen's Park, a large and beautifully landscaped park with attractive entrance gates and lodges and fronting on Victoria Avenue. "Frank Webb Avenue", a much Crewe residential street recalls his name. He retired in 1903 to Bournemouth, he died in Bournemouth in 1906 aged 70. He had never married. A complex man, with great capabilities, deep sensitivity and tolerance yet sometimes an unapproachable martinet, blind to the faults of his compound locomotives.

Rufous elephant shrew

The rufous elephant shrew, rufous sengi or East African long-eared elephant-shrew is a species of elephant shrew in the family Macroscelididae. Found in Ethiopia, Somalia, South Sudan and Uganda, its natural habitats are dry savanna and subtropical or tropical dry shrubland. Elephantulus rufescens occupies the drywood grassland zone of East Africa. Elephantulus rufescens exhibits no sexual dimorphism; the proboscis is flexible. The species' tails can be long up to its head-to-tail length. Both adults and juveniles are similar in color; the dorsal fur is of fine texture and the coloring is brown, reddish-brown in color, or buff while the ventral fur coloring is white. The coloration of the dorsal fur is influenced by the color of the soil in which the E. rufescens lives. However, adults have white feet; the large eye is surrounded by a white ring, interrupted by a dark patch which extended towards the rear of the animal. The ears are large and without fur. A sternal gland is present on both females.

The sternal gland is indicated by fringed white hairs. Females have three pair of teats and the males have internal testes. Rufous elephant shrews are active throughout the day, with peaks in activity at dusk and dawn while having a midday rest. A mating male and female will build trails beneath leaf litter; the trails act as shelter and protection because the rufous elephant shrew does not build or use shelters or burrows. Throughout the trails are several rest spots for scent-marking and sunbathing. Moving the forefoot laterally to push aside leaf litter and other loose debris, E. rufescens constructs and maintains trails. The males spend most of their time cleaning the foraging trails. Except for foraging, all activities are performed in these trails. Trails act. Insects form the major food resource of their diet in the dry season, while seeds are consumed during periods of rain. E. Rufescens has not been observed sleeping with closed eyes, but has been observed resting with eyes closed for a period of 1 – 2 minutes.

During these rest periods, which occur in rest spot along the trails, E. rufescens keeps their feet under their body to allow for a quick escape. This species takes flight when the smallest noise is heard; this species is monogamous. They live in a matriarchal society in which the female of the pair dominates the male; the rufous elephant shrew gives birth to two precocial young per litter. The female gives birth by fallen tree limbs beside the trails, she does not stay will the neonates and only nurses them in infrequently and for only a short amount of time. The neonates remain in the parental trails, expanding their familiarity of the parental territory up to 14 days after birth. If the young wander into any neighboring rufous elephant shrew trails, the residing residents chase them out of their trails. Before the next litter is born, parents chase the previous litter for the trails resulting in dispersal or death of the previous litter. Olfactory communication between young E. rufescens and their parents is achieved through apocrine glands located on the underside of the young's feet.

Neonates less than five days old have been observed back-rubbing one of its parents. Parents crouch down, allowing the neonates to climb on their backs and vigorously rub their four feet in the fur in a rapid vibrating motion. Cooperation between the neonates and adults is necessary or the neonates will fall off; the act of back-rubbing allows neonates to deposit pedal gland products on the fur of the parents and in turn transfer parental odors to their own fur. The mixture of the scents creates a family odor. BBC Wildlife Finder - with video clip from Life Elephantulus rufescens at the IUCN Red List of Threatened Species
