WISSA : World Ice and Snow Sailing Association
The World Ice and Snow Sailing Association (WISSA) is the world’s oldest international organization dedicated to ice and snow sailing.
Since its founding in 1987 in Germany, WISSA has grown into a global community. Today, we unite athletes who harness the power of wind on frozen lakes and snowy terrains. Each year, our World Championship gathers competitors from around the globe. What truly sets us apart, however, is our passionate community—one that preserves the sport’s spirit, fosters innovation, and honors our tradition.
ISSWC 2026 has begun in Västerås.
Competitors have arrived, the ice is ready, and an exciting week of racing across all disciplines is now underway on Lake Mälaren. The Local Organizing Committee manages the event on site, and the official championship website remains the best place to follow updates and results throughout the week.
This world-class event is brought to you by the World Ice and Snow Sailing Association (WISSA), together with an outstanding Local Organizing Committee featuring the Swedish Skatesailing Association, JKV Sailing Club, Visit Västerås, and the Swedish Ice Sailing Federation.
