I suspect this story is somewhat related to kiteboarding. Or at least, here in Italy we are experiencing progressive restrictions to sailing freedom since the kiteboarding boom, due to the high number of accidents related to that sport. Unfortunately, rules don't make differences between kiteboarding and relatively safer windsurfing.
By the way, maybe this time the windsurfing industry will understand that a major threat to our sport is due to restrictions to beach and water access. In places like Maui there were little restrictions if any, so maybe this was unnoticed by the big companies based there; but in places like here, this is a real problem. Unfortunately, most windsurfers' individualist nature makes it difficult for us to act collectively; so I guess that it's also up to the companies to do something to defend their business. Hopefully this story will make something change.
