Formula Windsurfing is the high-performance, competitive course-racing format of the windsurfing world. This type of sailing boards enjoy a massive wind range that enables racing in winds from 7 to 35 knots, and are capable of reaching speeds of over 30 knots. ==History and beginnings== This class of windsurfing was born in the late 90's as an upgrade from funboard-type course-racing boards looking to lower wind limits and broaden wind strengths. Historically, board designers used to increase the length and volume of the boards in order to allow for sailing in lighter winds, but during the late 90's, some brands like AHD, Berky, Drops, ML, Pro-Tech, Roberts and Starboard started to work on alternative solutions. As a result, they came up with designs that widened and shortened the board length whilst retaining high volume, and used larger fins to get into planing earlier. They also moved the fins further back, which prompted newer concepts with different solutions around the tail of the boards to free the nose and decrease drag. To avoid ventilation in the fin area, flaps or steeped bottoms were used, the latter becoming the more widely adopted practice due to its durability and ease of use. Designs like these were only made possible thanks to technological advancements in the fin industry which allowed makers to assemble larger fins (around 50cm) that are able to stand the increasing sail size and fin pressure. In few years this concept was widely adopted by almost all Formula Windsurfing board factories. The concept of Formula Windsurfing as a class was formed by the joint effort of the International Board Sailing Association (IBSA) and the International Funboard Class Association (IFCA), and was successfully pioneered on the 24th of March 1998 in Brest, France. During the 4 days of competition the top 20 French funboard sailors raced ten eliminations in winds of 6 to 12 knots. The winner of the event was Erik Thieme on a 2.75m board powered by a 10.0m^2 sail. During 1999 many national funboard associations included Formula as a discipline in their national racing circuits. Four international Formula regattas were held, including the first Formula World Championships, in Belgium, won by Wojtek Brzozowski from Poland. The Formula Windsurfing Class was adopted as an ISAF "International" class in 2001. The International Formula Windsurfing Class is controlled by the International Sailing Federation and was launched in 1998. This class introduced rules that restricted competitors to one board with a maximum of 3 sails and 3 fins (changed to 2 fins in 2011〔http://www.formulawindsurfing.org/index.php?what=class〕). This prompted the designers into creating boards with a very wide wind range coupled with excellent upwind and downwind performance. Formula boards have now been restricted to 1m wide with fins up to 70cm long and maximum sail sizes of 12.5m^2. By changing the fin length, type and stiffness as well as the sail sizes these boards can be tuned for a wide range of wind and water conditions and suit a variety of different sized sailors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Formula Windsurfing」の詳細全文を読む スポンサード リンク
