This book is a slim volume that covers the fundamental aspects of dinghy handling for the beginner. As a primer in the sport, the book largely consists of very clear diagrams and pictures. The textual content is short and to the point, so I would recommend this book if you are actively involved in learning to sail and just want the core concepts in a nutshell to act as a review of what you have learnt on a sailing course. For more in-depth information into the scientific / technical reasons why boats behave in the water the way they do and their general dynamics, look elsewhere. All in all, short and sweet; it does exactly what it says on the tin.
