Dart 16
The Dart 16 is a one-design 4.80 m long sailing catamaran. It is designed to be sailed by two people. It races off a Portsmouth Yardstick of 863. History Design The Dart 16 is a modern beach catamaran that is fast, affordable, and seaworthy. Like most Dart catamarans except for the Dart 20 EXP it lacks the main boom, as well as daggerboards, spreaders, and complicated trimming mechanisms. The lower part of the hulls have skegs typical for a beach catamaran. The most noticeable difference to the popular Dart 18 and Sprint 15 catamarans is that the hulls are made out of Tecrothene, a thermo plastic. This material is very impact- and scratch-resistant, but somewhat heavier and harder to repair than fiberglass. The kick-up rudders are similar to the Hobie 16. The rigging consists of a rotating aero-dynamically shaped aluminum mast held by a forestay and two shroud wires. There is a trapeze for the crew. The mainsail does not have a boom is fully battened and is controlled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiberglass
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 GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catamarans
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing ve ...

Gennaker
A gennaker is a sail that was developed around 1990. Used when sailing downwind, it is a cross between a genoa and a spinnaker. It is not symmetric like a true spinnaker but is asymmetric like a genoa, but the gennaker is not attached to the forestay like a jib or genoa. The gennaker is rigged like a spinnaker but the tack is fastened to the hull or to a bowsprit. It has greater camber than a genoa (but significantly less camber than a spinnaker). This is optimal for generating lift at larger angles of attack. An early form of gennaker was the "gollywhomper", used briefly in the 1870s. The gennaker is a specialty sail primarily used on racing boats to bridge the performance gap between a genoa and a spinnaker. It is sometimes the only downwind sail on board because it is easier to use and less expensive than a spinnaker. Due to its geometry, the sail is less prone to collapsing than a spinnaker. A gennaker is optimal for a beam reach, while an asymmetrical spinnaker is optimal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trapeze (sailing)
In sailing, the trapeze is a wire that comes from a point high on the mast, usually where the shrouds are fixed, to a hook on the crew member's harness at approximately waist level. The position when extended on the trapeze is outside the hull, braced against it (or an extension of it outwards) with the soles of the feet, facing the masthead, and clipped on by a hook on the trapeze harness. This gives the crew member more leverage to keep the boat flat by allowing the crew member's centre of gravity to balance the force of the wind in the sails. An additional benefit is the ability to "walk" along the gunwale to balance the boat's trim fore and aft. This is necessary to prevent racing catamarans such as the Tornado from digging the bow into the water, also called pitchpoling, and causing a nosedive and often a spectacular capsize. Boats may have only one trapeze, such as the 420 and the 29er, where only the crew uses the trapeze. Dinghies, such as the International 14 and th ...

Rigging
Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—''standing rigging'', including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the ''running rigging'', including halyards, braces, sheets and vangs. Etymology According to the Encyclopædia Britannica Eleventh Edition "rigging" derives from Anglo-Saxon ''wrigan'' or ''wringing'', "to clothe". The same source points out that "rigging" a sailing vessel refers to putting all the components in place to allow it to function, including the masts, spars, sails and the rigging. Types of rigging Rigging is divided into two classes, ''standing'', which supports the mast (and bowsprit), and ''running'', which controls the orientation of the sails and their degree of reefing. Configurations differ for each type of rigging, between ''fore-and-aft rigged'' vessels and ''square-rigged'' vessels. Standing Standin ...

Hobie 16
The ISAF International Class Hobie 16 (H16) is a popular catamaran manufactured by the Hobie Cat Company for racing and day sailing. The craft was the driving force behind the popularization of beachcats and was recently inducted into the Sailing Hall Of Fame. Introduced in 1971, the Hobie 16 is the second largest boat fleet in existence with over 135,000 boats built to date. The boat is distinctly recognized for its asymmetric "banana" shaped hulls, designed to work without the need for daggerboards so the catamaran could be run up the beach without worry. The rudders kick up automatically by lifting up on the tiller crossbar. Design The Hobie 16 is manufactured in France by the Hobie Cat company, and by the Hobie Cat of America company in the United States. The Hobie 16 normally carries two sails, the mainsail and the jib. There is a kit to allow an H16 to fly a spinnaker but this is only class legal for youth racing. Each hull has two pylons (the forward ones are ven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprint 15
The Dart 15 is a one-design glassfibre sailing catamaran, principally sailed in the UK. It is designed to be sailed by one or two people and has a furling jib and trapeze. It can be raced with or without the jib and trapeze, and there are national championships held in both categories. Between 2005 and 2022 the class was known as the Sprint 15. Weight Hull 33 kg per hull; Trolley 6 kg; Road base 100 kg; Trailing weight 174.5 kg; Mast 10.5 kg.

Dart 18
The Dart 18 is a one-design long glassfibre sailing catamaran. It is designed to be sailed by two people and can achieve speeds of up to 20 knots. This is reflected in its Portsmouth Yardstick of 805 and D-PN of 76.3 History The Dart 18 was designed and built by Panthercraft, which was formed in 1969 The very first Dart 18, designed and built in Falmouth, Cornwall, is now owned by the National Maritime Museum Cornwall. Up to the present, a number of improvements have been made, but the original concept was preserved through strict class rules. More than 8350 boats have been built up to 2016, which are sailed in more than 16 nations on 4 continents. Since 2012, Windsport International holds the worldwide licence to build the Dart 18. The boats are manufactured since 2005 at Collins Fibreglass Plastics in South Africa and in Europe. The World Championship results can be found here.

Spreader (sailboat)
A spreader is a spar on a sailing boat used to deflect the shrouds to allow them to better support the mast. The spreader or spreaders serve much the same purpose as the crosstrees and tops Total Operations Processing System (TOPS) is a computer system for managing railway locomotives and rolling stock, known for many years of use in the United Kingdom. TOPS was originally developed between the Southern Pacific Railroad (SP), S ... in a traditional sailing vessel. Spreader design and tuning can be quite complex. The spreaders may be fixed (rigid) or swinging (pivoted at the mast). The purpose of the spreaders is to control, by either limiting, or inducing, bend into the spar so that when the windward shroud is loaded the mast achieves the desired bend characteristics. The spreaders may be designed to be angled in a way that either forces bend in to the spar or reduces bend, depending on the desired results.
