Naish S25 Wing Surfer 3.6m , In mint condition and suit light / small riders + strong winds , compact and small with high visibility windows The original Naish Wing-Surfer was designed as a one size does it all SUP and surf-foil wing that has launched a whole new era in wind-powered watersports. The S25 Wing-Surfer takes the first generation Wing-Surfer's basic design principle and carries it into the future. What has not changed is the pure, simple, pump-and-go design philosophy. But the changes made to the new Wing-Surfer are many and address the demands of a rapidly growing new sport.
