My respect is beyond the limits.

Race Program: course race, minimum 3 races, maximum 8 races.
Definition of Divisions: a kite belongs to division "8" or "10" if its span on the flat surface is less than 8m or 10m correspondently.

The winds of change and new energy blew across the WISSA 2011 race courses in Oravi, Finland last week. The 31st annual WISSA Ice and Snow Sailing World Championships was blessed in many ways. Good winds, great people, an excellent organizing team, and a wonderful venue all came together at Oravi in the beautiful Saimaa region of southeastern Finland.
The WISSA World Championships has come a long way from its original roots as a winter windsurfing championships. As each new technology emerged, WISSA immediately reached out to embrace the new format. As a result, the WISSA ISSWC is the longest running competition in the history of all of the above classes - ironic given that windsurfing and kite sailing are generally known to be water sports.
Stay tuned. There is a LOT more coming.
