Query: Better than Sailing For Dummies for dummies like me.

I wish I had gotten this before I bought Sailing For Dummies. Sailing For Dummies somehow left me with a lot of unanswered basic questions about sailing. Complete Sailor answered those questions. Complete Sailor also has more illustrations that provide a clearer understanding of just what the heck the author's talking about.
