Tasar
The Tasar is a fiberglass 2 person sailing dinghy with a mainsail and jib. Designed by Frank Bethwaite of Sydney in 1975, the boat was technologically advanced for its time and continues to evolve. Aimed at a husband-and-wife or parent-and-child crew hence no spinnaker, it is designed for a combined crew weight of around 140 kg. The hull weighs 68 kg, and is of sandwich foam construction. The hull has a fine angle at the bow to reduce wave impact drag with unusually clean and sharp chines aft to ensure very free planing and outstanding stability. The foam cored hull is stiff and light and the advanced hull shape, together with an innovative rig which combines a rotating mast with a fully battened main sail, allows the Tasar to plane upwind with the crew normally hiked. The wide beam and a cockpit designed for comfortable hiking make the Tasar easy, fun and very exciting to sail in winds up to . The Tasar is an international class, with strong fleets in Australia, USA, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monohull
right A monohull is a type of boat having only one hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stability; even heavily laden cargo ships use ballast to optimize the di ...

PET Film (biaxially Oriented)
BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical stability, dimensional stability (fabric), dimensional stability, Transparency (optics), transparency reflectivity, and electrical insulation. When Metallised film, metallized, it has gas and moisture barrier properties. The film is "biaxially oriented", which means that the polymer chains are oriented parallel to the plane of the film, and therefore oriented over two axes. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the best-known trade names are Mylar, Melinex, Lumirror and Hostaphan. It was the first biaxially oriented polymer to be manufactured on a mass commercial scale.

Sandwich Foam
A sandwich is a dish typically consisting variously of meat, cheese, sauces, and vegetables used as a filling between slices of bread, or placed atop a slice of bread; or, more generally, any dish in which bread serves as a ''container'' or ''wrapper'' for another food type, and allows it to be a finger food. The sandwich began as a portable, convenient food in the Western world, though over time it has become prevalent worldwide. There has been social media debate over the precise definition of ''sandwich'', specifically whether a hot dog or open sandwich can be categorized as such. Other items, like hamburgers and burritos, were also considered. In the United States, the Department of Agriculture (USDA) and the Food and Drug Administration (FDA) are the responsible agencies for protecting the definition of ''sandwich''. The USDA uses the definition, "at least 35% cooked meat and no more than 50% bread" for closed sandwiches, and "at least 50% cooked meat" for open sandwich ...

One-Design
One-design racing is a racing method which may be adopted in sports using complex equipment, whereby all vehicles have identical or very similar designs or models, avoiding the need for a Handicapping, handicap system. Motorsport One-make racing series (also known as spec racing series) are racing series in which all competitors race with identical or very similar vehicles from the same manufacturer and suppliers. Typically, this means the same type of chassis, powertrain, tyres, brakes, and fuel are used by all drivers. The idea behind one-make car racing is that success will be based more on driver skill and Racing setup, car setup, instead of engineering skill and budget. One-make series are popular at an amateur level as they are affordable, due to the use of a common engine and chassis.

Spinnaker
A spinnaker is a sail designed specifically for sailing off the wind on courses between a Point of sail#Reaching, reach (wind at 90° to the course) to Point of sail#Running downwind, downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually nylon, and are often brightly colored. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. They are attached at only three points and said to be ''flown''. Etymology Some dictionaries suggest that the origin of the word could be traced to the first boat to commonly fly a spinnaker, a yacht called ''Sphinx'', mispronounced as ''Spinx''.
