context_page_description: A surfboard is an elongated platform used in surfing. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as papa he'e nalu in the Hawaiian language, they were usually made of wood from local trees, such as koa, and were often over 460 cm in length and extremely heavy. 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 result is a light and strong surfboard that is buoyant and maneuverable. The Polystyrene surfboard was invented by Reginald Sainsbury of Wilcove, Torpoint in the early 1960s whilst working for the Poron Insulation company, Millbrook, Cornwall who were looking to expand into the leisure industry.
context_section_description: A surfboard leash or leg rope is the cord that attaches a surfboard to the surfer. It prevents the surfboard from being swept away by waves and stops runaway surfboards from hitting other surfers and swimmers. Modern leashes comprise a urethane cord where one end has a band with a velcro strap attached to the surfer's trailing foot, and the opposite has a velcro strap attached to the tail end of the surfboard.
  Jack O'Neill lost his left eye in a surf leash accident as the surgical tubing used in the early designs allowed the leash to overstretch, causing the surfboard to fly back towards the surfer. Subsequent cords were made with less elastic materials.
