About CWSA
Wakesurfing, run as a sport.
The Competitive Wake Surf Association (CWSA) is the international federation that connects the wakesurf community worldwide. Through sanctioned events, world rankings built on the World Ranking System (WRS), and a single set of competition rules and judging criteria, CWSA is developing wakesurfing into a sport where everyone is measured the same way.
Whichever country an event is held in, the same rules, the same judging criteria and the same points calculation apply. That is why a result earned in Japan counts directly toward the World Ranking. CWSA JAPAN's role is to explain how that system works, accurately and in Japanese, and to connect Japanese athletes to the world stage.
