The book's strengh is in the detailed navigational information that warns you, for example, where a tight bend is coming up that will require you to listen carefully for the horn of any commercial vessels before proceeding. It is logically laid out and easy to follow, with good schematic maps. These maps have no scale, which makes planning trips more difficult but bridges and locks are clearly shown. If you have little inland waterways experience you will need information on european regulations (there is an RYA guide available) and advice on the basics of how to tie-up, negotiate locks etc'. This could have be included very easily with just a few extra pages on each topic but as this information is missing you have to buy two extra books unless you already have the experience. This is a prety slim volume and is worth the money at Amazon's reduced price but is nowhere near extensive enough to justify the full cover price. One point of detail: the author recommends using the french tourist offices if you want a combined boating and land-based holiday. Definitely do not do this. They have a lot of poor quality property, often without much information before you can book. Use the online holiday letting websites and choose places that have lots of internal and external photos showing you exactly what you're getting. Also I couldn't see any reference to the cheapest boat hire company which is 'Ad Navis', based at Agde. One final piece of advice - take your bikes with you or hire them from the boat company, an absolute must to get you to the resturants, wine 'caves' etc'!
Happy boating!
