Books on the Racing Rules of Sailing are always very well thumbed being opened and closed numerous times in use, so having it in 'ring bound' form is a very good idea as is having the pages waterproofed.
The definitions are in blue. These are followed by the RYA Racing Charter in yellow. The contents pages, introduction, 'Basic Principles' and Part 1 are then in white with the all important Part 2 in blue. This makes it easy to find the section you're looking for. All of the RRS are there and at the end of the book - in yellow again are the RYA Prescriptions, Guidance Notes and a short piece on Competitor Misconduct.
It is important to understand that this book is just the RRS together some some further useful information from the RYA, there are no interpretations or explanations. They would be nice and then it would have 5 stars!
