The author, Roger Barnes, has sailed in yachts as well as dinghies. He decided to sail open boats, small enough to trail behind a car, so that he could explore local and more distant shores.
The Manual manages to juggle between the fine line of comedic and factual texts. It provides useful and no doubt life saving information that would help you survive in the the wild until the rescue crew arrived.
This book is written, as the title suggests, with the dual purpose of regaling the reader with an account of Rod and Lu Heikell's most recent circumnavigation, while giving copious advice and information on eating out, provisioning and catering on board along their 30,000 mile plus route.
