On the ISAF Site the Racing Rules of Sailing for the next cycle have been published:
I spoke to the rule 18 working party's chairman Dick Rose, a couple of weeks back, regarding the date on publication. In order to prevent misinterpretation of the new rules, the working party wanted to publish a explanatory document outlining the changes and effects. They hadn't counted on the faster pace of the www and wanted to publish around November/December.
I've been send a preliminary copy of that document and in the next couple of weeks I will again be posting about the new rules and giving you a heads up on the explanation of the working party.
