Sailing is a bit like driving a car - you have to know and observe the rules. We will call these "The rules of the road". NSW Maritime publishes a book on boating rules, for power boats and sailing boats, called the Boating Handbook.
We will refer to the Boating Handbook during the course, so you might want to download it.
