By E-mail I was notified about a link on the RYA-site. (Thanks Brass!)
It is a extensive PowerPoint presentation about all the changes in the Racing Rules of Sailing 2009-2012, made by Trevor Lewis.
From the RYA site:
Many Clubs will be looking for something to help fill up their Winter programme. Down loading this PowerPoint presentation could help, with a little homework any qualified race official or proficient sailor should be able to deliver this hour long presentation. On the other hand your local Regional Rules Advisor may be able to find a local expert to come and deliver it for you. To find your local Advisor, please email (see RYA site)
Download the PowerPoint presentation accessible from the link at the bottom of the page, and open it up in presentation mode. The first slides will help you set up your computer to be able to deliver it. Slide 4 is a menu where you should choose the last option, “Quick Guide.” This is the part to use.
For those wanting to prepare in depth or you are curious to discover more, the rest of the presentation will provide you with a detailed step by step route through all the new changes in the Racing Rules of Sailing 2009 – 2012.
