Ljungström Sailboat
Ljungström sailboats were created by the Swedish engineer Fredrik Ljungström, who was interested in sailing since childhood. A "Ljungström sailboat" typically has a "circular arc" hull and a "Ljungström rig". A Ljungström rig mast has no mast stays. The mast rotates on two ball bearings often flying double mainsails, with no foresails. In their time the Ljungström sailboats were a minor revolution as they were fast, safe and easy to sail as well as relatively easy and affordable to produce. The models were named The Wing and the number (Swedish Vingen 1, Vingen 2 etc.) chronologically. A few models were built in series, such as Vingen 11A and the Twin Wing which was specifically produced for the US market. The design was not appreciated by the fairly conservative yacht clubs at the time, so development was done with scarce means. Approximately sixty boats (of different sizes) were produced. Approximately eighteen are known to still exist; a dozen of those are sailing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dowel
A dowel is a cylindrical rod, usually made of wood, plastic, or metal. In its original manufactured form, a dowel is called a ''dowel rod''. Dowel rods are often cut into short lengths called dowel pins. Dowels are commonly used as structural reinforcements in cabinet making and in numerous other applications, including: * Furniture shelf supports * Moveable game pieces (i.e. pegs) * Hangers for items such as clothing, key rings, and tools * Wheel axles in toys * Detents in gymnastics grips * Supports for tiered wedding cakes Wood dowel Manufacturing process The traditional tool for making dowels is a ''dowel plate'', an iron (or better, hardened tool steel) plate with a hole having the size of the desired dowel. To make a dowel, a piece of wood is split or whittled to a size slightly bigger than desired and then driven through the hole in the dowel plate. The sharp edges of the hole shear off the excess wood.Ivin SickelsExercises in Wood-Working American Book Company ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Russian Circular Yacht 'Popovotchka' - The Graphic 1876
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pr ...

Saab Group
Saab AB (originally , later just SAAB and Saab Group) is a Swedish aerospace and defence company, founded in 1937. Headquartered in Stockholm, the development and the manufacturing is undertaken in Linköping. Saab produced automobiles from 1947 until 1990 when the automobile division was spun off as Saab Automobile, a joint venture with General Motors. The joint venture ended in 2000 when GM took complete ownership. From 1968 onwards the company was in a merger with commercial vehicle manufacturer Scania-Vabis, known as Saab-Scania. The two were de-merged in 1995 by the new owners, Investor AB. Despite the demerger, both Saab and Scania share the right to use the griffin logo, which originates from the coat of arms of the Swedish region of Scania.

Parts Of A Sail
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 (e.g. ''fore-and-aft'') and its shape, (e.g. ''(a)symmetrical'', ''triangular'', ''quadrilateral'', etc.). 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. Whereas conventional sails form an airfoil with one layer of fabric, wingsails comprise a structure that has material on both sides to form an airfoil—much like a wing placed vertically on the vessel—and are beyond the scope of this article. Classifications Sails may be classified as either ''triangular'', which describes sails that either come to one point of suspe ...

Shroud (sailing)
On a sailing boat, the shrouds are pieces of standing rigging which hold the mast up from side to side. There is frequently more than one shroud on each side of the boat. Usually a shroud will connect at the top of the mast, and additional shrouds might connect partway down the mast, depending on the design of the boat. Shrouds terminate at their bottom ends at the chain plates, which are tied into the hull. They are sometimes held outboard by channels, a ledge that keeps the shrouds clear of the gunwales.''The Lore of Ships,'' ed. by Bengt Kihlberg. Göteborg :Tre tryckare & New York: Holt, Rinehart & Winston, 1963. Shrouds are attached symmetrically on both the port and starboard sides. For those shrouds which attach high up the mast, a structure projecting from the mast must be used to increase the angle of the shroud at the attachment point, providing more support to the mast. On most sailing boats, such structures are called spreaders, and the shrouds they hold contin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reefing
Reefing reduces the area of a sail, usually by folding or rolling one edge of the canvas in on itself and attaching the unused portion to a spar or a stay, as the primary measure to preserve a sailing vessel's stability in strong winds. Restoring full sail area is termed ''shaking out'' a reef. Whereas fore-and-aft rigged vessels store the unused portion of the sail on a boom, below the sail, square-rigged vessels stow the unused portion on a spar, above the sail. Reefing may occur by rolling the sail around its luff or foot, either on a rotating stay or within a spar. Fore-and-aft rigs Sails may have built-in alternative attachment points that allow their area to be reduced. In a mainsail, pairs of grommets, called reefing tacks, reefing clews, or reefing cringles may be installed in the sail; a cruising boat will typically have two to three pairs. Pulling these points down to the boom forms a new tack and clew, reducing the sail's area. Using the pair of grommets closest ...

Ljungström Rig
Ljungström rig is the name for the sailing rig designed by Swedish engineer Fredrik Ljungström with double main sails and rotating mast, but without boom, foresail, forestay and shroud. The early models of the Ljungström sailboat had a stern stay but this was omitted around 1945, before the model 12 (Vingen 12). The Ljungström rig is competitive towards the competing rigs from that time when close hauled and full run but is lacking at beam reach and broad reach. Its main purpose and advantage is, however, safety and ease of handling. History The first Ljungström rig was developed by the Swedish engineer Fredrik Ljungström to enhance safety at sea. The family had been close to severe accidents with the traditionally rigged Ebella, nowadays named Beatrice Aurore, when in hard weather the crew had to walk on deck to take in sail. Ljungström, in order to not risk the safety of his crew, designed a boomless rig handled completely from the cockpit. Components Mast The m ...
