Ski Jumping skis are made of wood and fiberglass. They are longer, wider and heavier than skis used in other skiing events. The length of the ski is determined by a formula that takes into consideration the height and weight of the skier. The minimum length for a ski is 6.7 feet (207 centimeters). A skier whose height is 4.9 feet (150 centimeters) and whose weight is 90 pounds (41 kilograms) would use this ski. The maximum length for a ski is 9.5 feet (292 centimeters). A skier whose height is 6.5 feet (200 centimeters) and whose weight is 176 pounds (80 kilograms) would use this ski. If a skier should fall outside of these parameters then the maximum ski length is 146% of the skiers height. The weight of a single ski corresponds to the length of the ski, i.e. if the ski is 240 centimetres in length the weight will be 2.40 kilograms. Just insert a decimal point between the 1st and 2nd number. So the minimum weight for a pair of skies would be 9.1 pounds (4.14 kilograms) and the maximum would be 12.8 pounds (5.84 kilograms). Ski jumping skis are more flexible then other types of skis, this flexibility is called the Camber. The Camber is the arc in the ski that allows the weight of the ski jumper to be distributed along the whole ski and not just in the centre of the ski.
