Query: Excellent book

An excellent book about mutihulls, practical, for people who want to sail. Not for people who sail one week a year and have $200,000 holes in the water or people who want air conditioning and tv in their boats. If you want to experience sailing and the ocean, this is the book for you. This book will tell you what you need, what works and doesn't, and how to be safe, written by a man who has done some hard thinking on the subject. Entertaining and enjoyable reading. I wish he would write more books. Highly recommended.
