The classic skiing consists of three disciplines: Slalom, Figures and jumping. During a competition, a skier may choose to participate in one or more of these disciplines. A skier who chose to participate in all disciplines is assigned a score for the combined disciplines plus a note for individual disciplines.
The slalom course is done at a maximum speed of the boat of 58km / h for men and 54km / h for women. The starting length for a slalom rope is 18.25m. When a skier successful passage through the course at the maximum speed of his category, the rope is shortened. She then goes to 16 m and 14,25 m, 13 m, 12 m, 11,25 m and then by fraction of 0,50 m.
The ski for the figures is smaller than a conventional ski and does not have drift. It is therefore easier to slide laterally on the ski and make skids.
The jumping discipline is to perform the longest possible jump. Of the three classic disciplines, it is the most extreme and spectacular. The Canadian Jaret Llewellyn is currently the world champion.
The jump is done on a pair of skis specially designer for this discipline. The skier, towed by the boat swings at a platform length 6.40m to 6.70m from the water and a height from 1.50m to 1.80m. The maximum boat speed is 51km / h for women and can reach 57km / h for men. Some skiers can reach distances of nearly 90m (300 feet).
Among the equipments of the jumper we also find a safety helmet and a padded thermal combination.
