This is a 161-page ebook (actually a large pdf file) containing pretty much everything I have learned about canals, narrowboats and being afloat. Starting with an overview of the canal system, I go on to talk about the different people and boats who use the inland waterways, then delve into detail about boat layouts, handling, life afloat and so on. It's like a giant "Frequently Asked Questions" page enhanced with photos, reference links, a substantial index and glossary of terms.
