surf boards 1

Surfboards are elongated platforms used in the sport of surfing. They are relatively light, but strong enough to support an individual standing on them while riding a breaking wave. They were invented in Hawaii, where they were known as Papa he‘e nalu in the Hawaiian language, usually made of wood from local trees, such as koa, and were often over 15 feet (5 m) in length and extremely heavy.[1][2] Major advances over the years include the addition of one or more fins on the bottom rear of the board to improve directional stability, and numerous improvements in materials and shape.

Modern surfboards are made of polyurethane or polystyrene foam covered with layers of fiberglass, cloth and polyester or epoxy resin. The end result is a light and strong surfboard that is buoyant and maneuverable. Recent developments in surfboard technology have included the use of carbon fiber.

Most modern surfboards can be divided into two main categories: longboards and shortboards. Longboards, as the name suggests, are longer (often 8 ft/2.4 m or more), and are also thicker and wider, with a more rounded nose than a shortboard. Shortboards are shorter (5–7 ft/1.5–2.1 m), thinner, and have a more pointed nose. They are not as wide as longboards and are typically more maneuverable. Other variants include guns, longboard guns, olos, fun-boards, fish, eggs, bonzers, quads, tow-boards, and hydrofoils. In order to discuss board design, it is helpful to have basic knowledge of the vocabulary used to reference each part of the board.Surfboards are usually constructed using polyurethane foam. They are made stronger with one or more small pieces of wood, called a stringer, going down the middle of the board. The foam is molded into a "blank", in the rough shape of a surfboard.[3] Once the blanks have been made they are given to shapers. Shapers then cut, plane, and sand the board to its specifications. Finally, the board is covered in one or more layers of fiberglass cloth and resin. It is during this stage that the fins, or boxes for removable fins, are put on and the leash plug is installed. Another method of making boards is using epoxy resin and polystyrene foam, instead of polyester resin and polyurethane foam. In recent years, surfboards made out of balsa and a polystyrene core are becoming more popular. Even solid balsa surfboards are available.

Although boards are usually shaped by hand, the use of machines to shape them has become more popular over the years. Modern technology has made its way into surfboard production as well. Vacuum forming and modern sandwich construction techniques borrowed from other industries have become more common in the industry. Many surfers have switched to riding sandwich-construction, epoxy boards. These boards have become especially popular with beginner surfers as they provide a cheaper entry level surfboar
