I oppose giving any areas up voluntarily, and strongly back self regulation, if imminent restrictions are coming (eg exclusion zones) then you start the negotiations be it for surfing windsurfing or kitesurfing for that matter, once things are set they are very hard to reverse
dont loose sight that user conflict is what this all is aimed at trying to resolve and there are significant amounts of time during the year when the other users are a minority,
Familys swimmers sun bathers etc are only there in large numbers for a reasonably small part of the entire year eg weekends when its hot/sunny, not windy and generally pleasent conditions over the warmer months,
as soon as its windy and cool their numbers are reduced considerably. Over the winter months they are almost non existent except for surfers, kiters and windsurfers further When there is a significant wind in winter these numbers are reduced to allmost nil
why give up areas when there is so much time when they are hardly used by the other party's?? and are not even bothered to be patrolled by the authorities(SLSC)
what about those onshore days in winter when you need all the beach you can get to get out, why give it up for no reason when there are no significant numbers of other users in the water with no beach patrol

I'm not saying it makes it ok to buzz a person who does choose to swim, the same common sense rules should prevail,
Unfortunately some persons choose to vent their anger over peoples behaviour on a online forum to no avail, remaining anonymous when they could have dealt with the situation at the time and made some real attempt at self regulating a spot if they felt so strongly about it
Most of the guys at brighton know each other and have for some time, every one I know who kites there is well approachable, it seams the guys that make all the noise choose to remain anonymous acheiving very little about what they are preaching. If you want to make a difference make yourself known to the regular users and offenders of this beach
