The third factor improving stability is yaw stability, which keeps the wingsurfer in the direction intended. If the wing is turned obliquely, for instance by a gust, the forward half of the wing generates more drag, forcing the wing back to neutral position. Drag The drag of an aircraft wing is divided into parasitic and induced drag. Parasitic drag is generated by all the fixed parts of the sail and rig that collide with air in movement. It can be further analyzed into profile and form drag.
Profile drag is generated by friction between the wing and the air.
Form drag involves all other components, such as the rig and the surfer himself or herself. This factor can be influenced by wearing appropriate clothing and adopting the correct posture. Induced drag is generated by reduced efficiency as the air flow escapes the wingtips and causes a tip vortex. Once you put these technical concepts aside, the Skimbat Wingsurfer is without a doubt, one of the more fun winter recreations. All you need is some wind, a frozen lake or a snow covered field and the desire to dance with the wind.
