I quote a bullet point from the front cover: 'Through routes to the Med'.
The relevant chapter (15) consists of exactly 3 pages, and I quote from the chapter:
'The intention of this chapter is not to cover the various routes in detail, but to give some sound and very practical advice...' - utterly contrary to the promise on the front cover!
Sorry, but since my main interest was specifically to take a boat through the canals to the Mediterranean this section is utterly useless and not at all 'what it says on the tin'!
Otherwise the rest of the book is informative and helpful.
So, if like me you were hoping to learn about the various through routes to the Med, then unfortunately this is not the book for you.
