Dragonfly Trimarans
Dragonfly Trimarans is a line of trimaran sailboats built by the Quorning Boats shipyard in Skærbæk, near Fredericia, Denmark. The trimarans produced by this shipyard are characterized by a folding technology denominated "SwingWing". This allows them to use marina berths intended for monohulls and be trailerable. The smallest model, the Dragonfly 25, is narrow enough (2.3m) to not need special permits, as is the Dragonfly 28 (which at 2.54m is just under the 2.55m legal limit in the European Union). These trimarans have low draft and can be beached since both the centreboard and the rudder can be lifted. History Quorning Boats was founded in 1967 by Børge Quorning. In 1981 the company dropped the monohulls and started to produce exclusively the Dragonfly range of trimarans. These early trimarans were not foldable. In 1988-89 the “Swing Wing” system was designed and developed. It was first introduced in 1989 in the Dragonfly 800 Swing Wing, and has been used in all models si ...

Trimaran
A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs. Terminology The word "trimaran" is a portmanteau of "tri" and "(cata)maran", a term that is thought to have been coined by Victor Tchetchet, a pioneering, Ukrainian-born modern multihull designer. Trimarans consist of a main hull connected to outrigger floats on either side by a crossbeam, wing, or other form of superstructure—the traditional Polynesian terms f ...

Numerical Control
Numerical control (also computer numerical control, and commonly called CNC) is the automated control of machining tools (such as drills, lathes, mills, grinders, routers and 3D printers) by means of a computer. A CNC machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following coded programmed instructions and without a manual operator directly controlling the machining operation. A CNC machine is a motorized maneuverable tool and often a motorized maneuverable platform, which are both controlled by a computer, according to specific input instructions. Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions such as G-code and M-code, and then executed. The program can be written by a person or, far more often, generated by graphical computer-aided design (CAD) or computer-aided manufacturing (CAM) software. In the case of 3D printers, the part to be printed is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astusboats
Astusboats is a French trimaran manufacturer based in Brech. The trimarans produced by this shipyard are designed by Stéphan Vallet, and have the characteristic of being trailerable due to the telescopic tubes in which the floats are mounted (except for the 14.1 model which is narrow enough to be trailed with the floats in place). Product line The current product line is: * Astus 14.1 (2007) * Astus 16.1 (2006) * Astus 18.1 (2010) * Astus 20.1 (2005) - discontinued * Astus 20.2 (2009) * Astus 22.1 (2008) See also * List of multihulls Types * catamaran = two symmetric hulls * proa = two asymmetric hulls, reverse-shunting (interchangeable bow/stern) * trimaran = three hulls * quadrimaran = four hulls * pentamaran = five hulls Pre-modern Austronesian * ʻalia * Amatasi * B ...

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 ...

Sail
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air p ...

Cruising (maritime)
Cruising by boat is an activity that involves living for extended time on a vessel while traveling from place to place for pleasure. Cruising generally refers to trips of a few days or more, and can extend to round-the-world voyages. History Boats were almost exclusively used for working purposes prior to the nineteenth century. In 1857, the philosopher Henry David Thoreau, with his book ''Canoeing in Wilderness'' chronicling his canoe voyaging in the wilderness of Maine, is considered the first to convey the enjoyment of spiritual and lifestyle aspects of cruising. The modern conception of cruising for pleasure was first popularised by the Scottish explorer and sportsman John MacGregor. He was introduced to the canoes and kayaks of the Native Americans on a camping trip in 1858, and on his return to the United Kingdom constructed his own 'double-ended' canoe in Lambeth. The boat, nicknamed 'Rob Roy' after a famous relative of his, was built of lapstrake oak planking, dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
