I have filled out the survey and said my piece. Have a look at the different rules for windsurfers as opposed to kayaks. I.e. windsurfers you are not allowed to be basically half the harbour and if you do we will fine you $1500. Kayakers if possible stay outside the channel (your draft is 10cm) and no mention of any real fine. I'm not trying to have a go at kayakers but just point out that rules should be broadly consistent for all small craft on the harbour. There are not as many windsurfers as there use to be, and the rules need revision. Sailboarding is an Olympic sport and sailboarders should come under the same rules as sailing boats. Here's your chance there is chance to comment right at the end of the survey.
