Surfboards were invented by the Hawaiians for riding breaking waves to the beach. .]] MATERIALS Originally made of Wood or Balsa the first surfboards were often over 15 feet in length and extremely heavy. The major advances over the years were the addition of a Fin on the bottom rear of the board to improve directional Stability and a change of materials. Modern surfboards are made of Polyurethane or Polystyrene foam covered with layers of Fibreglass cloth and polyester or Epoxy Resin . The end result is a light and strong surfboard that is Buoyant and Maneuverable . Long-boards as the name suggests are longer (9+ft), and also thicker, wider and with a more rounded nose than a short-board. Short-boards are shorter (5-7ft), thinner, and have a more pointed nose. They are not as wide as long-boards and are typically more maneuverable. DESIGN Both have Fins which create stick and drive on the wave face. The most common fin arrangement is named the Thruster invented by Simon Anderson of Australia , which consists of three fins, one at the tail of the board and two slightly further towards the nose of the board. The purpose of the 3 fin thruster setup is to provide more maneuverability and responsiveness on a wave face. CONSTRUCTION Surfboards are usually constructed using polyurethane foam. They are made stronger with a small piece of wood going down the middle of the board called a stringer. The foam is molded into the rough shape of a surfboard called a blank. Note: Recently, the largest producer of these blanks: , Stewart Surfboards , and Rusty . MODERN CLASSIFICATIONS
Note the sizes given above are approximate overall lengths and are intended for guideline purposes only. Similar to the approach of surfing waves, there are no hard and fast rules for the board that you use to do so. EXTERNAL LINKS SEE ALSO |
