Every four years after the Olympics ISAF issues a new rule book with rule changes. They try not change them in between but often after major changes (as we had last year) there are a few loopholes to plug.   That is the case this year. I often find these changes to be hard to write about. The loopholes are often pretty obscure and since they are fixed it means I would have to explain a loophole that isn’t there anymore.   What I am going to do is show you situations and show how the fixed rule works. If you want to understand the loophole you will have to either figure it out or attend a seminar where I am willing to explain it.   Three rules were fixed this year, 18.2(c), the definition of Obstruction and the definition of Party.   There was also a fix within the match racing appendix which I won’t cover here. All of these changes take effect January 1, 2010.
