Complete Sailing Manual by Steve Sleight is, without any doubt, the most extensive and complete "how to sail" manual for beginners. It's a good reminder for information concerning simple, but indispensable things in dinghies. For more advancing sailing it's chapter about "sailing in regatta dinghies" is a little incomplete and vague, as it would have to have close details on high performance dinghy classes. This look upon high perfomance dinghy classes would be very helpfull to people who sail in suck kind of boats, because books regarding those kind of boats are quite rare or hard to find. For example the trapeze chapter lacks of diagrams or information regarding regatta and tactic data. The rigging systems also lacks of variety: the systems showned in this book are very few, for there are inumerous dinghies with inumerous rigging system.
The begginer section is very well constructed and illustrated, with diagrams and self-explainatory pictures. I recommend this book to persons who began to sail.
I myself used this book to search for informations that I've forgot, and I actually learnt various things with it. I've particulary enjoyed Hellen MacArthur's prologue.
Overall, this is an exelent book! With simple language, well written : good all-round work (but lacking on particular aspects of sailing!). My English isn't very good, so I ask for pardon in that matter! Buy the book!
