This is what I would describe as a booklet rather than a book. Some of the concepts could be described a bit clearer but never the less the book is thought provoking. Handling a boat through a lock usually requires two or more people. "Going It Alone" addresses the problems you will encounter when going through locks single handed. Some of the ideas left me feeling a bit uncomfortable with regards to personal safety. But then again it is hard to ensure your safe when working alone. There are hints and tips that I picked up in the booklet that I use even when we are double crewed.
Going It Alone by Colin Edmondson is a good read but not for the faint hearted to put into practice.
