I first came across this book during a racing seminar run by the author. As with all the current RYA endorsed books and manuals it hits the nail on the head with excellent diagrams and explanations which are easy to understand whether you are a novice racer or highly experienced pro.
There are some fantastic and often simple little tips that once you've learnt or understood them, are so obvious but so simple to employ in your pre-race and during race strategy you'll wonder how you ever got on before.
Without doubt, the information in this book WILL make you a better sailor and you'll understand WHY!
