Twister (yacht)
The Twister is a masthead rigged sloop, length , beam , draft . It has a full length keel and a full-depth transom-hung rudder which is tiller steered. Total displacement (empty) is about , of which is encapsulated lead ballast. This sailing yacht was designed in 1963 by the English yacht architect C.R. (Kim) Holman. History Kim Holman was born in Cornwall and established himself as a yacht designer on the English East Coast after World War II. On request of one of his clients he designed a small sailing yacht, optimised for the rating rule at that time, with lines inspired by the Folkboat. The new design was baptised "Stella", and was so successful in races that several were built in wood. After a few years demand came for a yacht with the same looks, but with more length, space and seaworthiness, while still keeping the same rating as the Stella. Holman met this challenge and called his design "Twister", because he felt he had advantageously 'twisted' the rules for measurem ...

Folkboat
The Nordic Folkboat (Swedish: Nordisk Folkbåt) is a Swedish sailboat that was designed by and Tord Sundén as a racer- cruiser and first built in 1942. Even though Sundén drafted the plans with design ideas provided by Iversen, Sundén was never credited as the actual designer of the boat.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 126-127. Houghton Mifflin Company, 1994. The Nordic Folkboat was developed into the Sundén-designed International Folkboat in 1967. The International Folkboat was expressly designed for fibreglass construction. The International 25 and the Olsen 26 are also based upon this design. The Junior Folkboat designed by actually dates from 1929. It was originally called the "Juniors Bad" (Junior boat), but was latter renamed because of its strong resemblance to the later and larger Nordic Folkboat. Production The design has been built by a number of different builders since the first were built in 1 ...

Circumnavigation
Circumnavigation is the complete navigation around an entire island, continent, or astronomical body (e.g. a planet or moon). This article focuses on the circumnavigation of Earth. The first recorded circumnavigation of the Earth was the Magellan–Elcano expedition, which sailed from Sanlucar de Barrameda, Spain in 1519 and returned in 1522, after crossing the Atlantic, Pacific, and Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth is straightforward, usually taking days instead of years. Today, the challenge of circumnavigating Earth has shifted towards human and technological endurance, speed, and less conventional methods. Etymology The word ''circumnavigation'' is a noun formed from the verb ''circumnavigate'', from the past participle of the Latin verb '' circumnavigare'', from ''circum'' "around" + ''navigare'' "to sail" (see further Navigation § Etymology). Definition A person walking completely around either pole ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bunk Bed
A bunk bed is a type of bed in which one bed frame is stacked on top of another, allowing two or more beds to occupy the floor space usually required by just one. They are commonly seen on ships, in the military, and in hostels, dormitories, summer camps, children’s bedrooms, and prisons. Bunk beds are normally supported by four poles or pillars, one at each corner of the bed. A ladder or stairs is used to get to the upper bed, which is normally surrounded by a railing to prevent the sleeper from falling out. Some models also have a privacy curtain for the lower bunk. Because of the need for a ladder and the height of the bed, the top bunk of a bunk bed is not recommended for children under six years of age. A loft bed is an elevated bed similar to a bunk bed, but without the lower beds, freeing floor space for other furniture, such as a desk, which might be built into the loft bed. Low loft beds are lower to the ground and designed for younger children. Types The most ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), 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. General features 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 (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

Glass-reinforced Plastic
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 ...

Stella (yacht)
The Stella is a 'one-design' Bermuda rig sloop yacht, designed for cruising and racing by the noted yacht designer CR (Kim) Holman in 1959. The design was to the requirements of a customer who had seen the Nordic Folkboat and decided that the English east coast needed a similar vessel but modified for North Sea as opposed to Baltic conditions and a competitive racer on handicap. The prototype: Stella No. 1 ''La Vie en Rose'' was built to win the 1959 Burnham (on Crouch) week, which she promptly did. Clinker built of mahogany or larch on oak frames. The restoration of ''Amulet'', an amateur built yacht similar to a Stella originally built in Fort William in 1964, is described by Bob Orrell in the book ''Amulet: A Charm Restored and Sailed to the Western Isles''. This boat is not actually a Stella (this is evident from the book and photographs) and is not recognised by the Stella Class Association. Fleets exist in the UK (estimated 100 built, mostly still extant) and Australia (a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

Masthead Rig
A masthead rig on a sailing vessel consists of a forestay and backstay both attached at the top of the mast. The Bermuda rig A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of Mast (sailing), 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 1600s; the t ... can be split into two groups: the masthead rig and the fractional rig. The masthead rig has larger and more headsails, and a smaller mainsail, compared to the fractional rig. The major advantage a masthead sloop has over a fractional one, is that the jib is larger. Since the jib has no mast in front of it to cause turbulent airflow over it, it is considered much more efficient than the main, especially for sailing up wind. Also, since the fore stay is attached to the top of the mast, it pulls directly against the back stay. Tightening the back stay, then, increases the tension on the fore stay. This is u ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A ...

Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel; some kay ...
