Bodyboarding 1 2007
Bodyboarding is a water sports, water sport in which the surfing, surfer rides a bodyboard on the crest, face, and curl of a wave which is carrying the surfer towards the shore. Bodyboarding is also referred to as ''Boogieboarding'' due to the invention of the "Boogie Board" by Tom Morey in 1971. The average bodyboard consists of a short, rectangular piece of hydrodynamic foam. Bodyboarders typically use Swimfin, swim fins for additional propulsion and control while riding a breaking wave. Origin Bodyboarding originates from an ancient form of riding waves (surfing) on one's belly. Indigenous Polynesians rode "''alaia''" (pronounced ah-lie-ah) boards either on their belly, knees, or feet (in rare instances). ''Alaia'' boards were generally made from the wood of ''Acacia koa'' and varied in length and shape. They are distinct from the modern stand-up surfboards in that they had no ventral fins. James Cook, Captain Cook recorded seeing Hawaiian villagers riding such boards when he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shark Island (Cronulla Beach)
Shark Island is a dangerous reef break about 100 metres off the coast of Cronulla, in Sydney New South Wales, Australia. It comprises a rock ledge that is fully exposed at low tide. The island is a well-known bodyboarding and surfing Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suita ... location. The wave can stand up fast and violently ("jack up" in surfing jargon), making it difficult and dangerous. The island is regarded by bodyboarders as producing one of the "heaviest" waves in the world. The annual Shark Island Challenge bodyboarding contest is held there, as well as the annual Shark Island Swim Challenge held at Cronulla Beach.

Bat Tail

Bodyboarding is also referred to as ''Boogieboarding'' due to the invention of the "Boogie ... design, Bat tail is used to describe a style of tail which was invented by Mike Stewart in the mid-1990s. The bat tail is essentially a combination of the clipped crescent tail and the square tail, which provides a balance of control and maneuverability. The additional "hump" located between the two outside tail pegs increases the tail's surface area, consequently elevating the rider's legs further out of the water and as a result, this reduces drag on the wave face. It is so named because when viewing the board bottom with the nose down, the outline of the tail somewhat resembles the ears and dome of the Batman's cowl. This results in increased looseness and speed with a reduction in stability (as com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeg
A skeg (or skegg or skag) is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. The term also applies to the lowest point on an outboard motor or the outdrive of an inboard/outboard."A small fin fitted aft of the keel to protect the rudder and propeller, and improve steering and tracking." "Skeg, or Skegg. A projecting stump formerly left on the keel, abaft the stern-post. The after-end of the keel. The composition piece supporting the heel of an equipoise rudder." at Internet Archive In more recent years, the name has been used for a fin on a surfboard which improves directional stability and to a movable fin on a kayak which adjusts the boat's Center of lateral resistance, centre of lateral resistance (it moves the center of resistance relative to the center of effort). The term is also often used for the fin on water skis in the U.S. It has been used for the vertical fin on seaplane hulls and floats. The wear-bar on the bo ...

Foam
Foams are two-phase materials science, material systems where a gas is dispersed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material. Note, this source focuses only on liquid foams. Note, this source also focuses on liquid foams. Foam "may contain more or less liquid [or solid] according to circumstances", although in the case of gas-liquid foams, the gas occupies most of the volume. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Etymology The word derives from the Old High German, medieval German and otherwise obsolete ''veim'', in reference to the "frothy head forming in the glass once the beer has been freshly poured" (cf. ''ausgefeimt''). Structure A foam is, in many cases, a multi-scale system. One scale is the bubble: materials science, material foams are typically randomness, disordered and have a variety of bubble sizes. At larger siz ...

Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. Polystyrene is naturally transparent to visible light, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and optical disc jewel cases), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled.
