I have Rudy and Jill's book Anchoring: A ground Tackler's Apprentice. It is by far the BEST anchoring book available. It provides the most in depth, pardon the pun, and complete view of anchoring technique, ground tackle equipment and accessories needed by any professional or recreational boat captain and crew. I have ten years of full-time cruising experience and learned about anchoring through trial and error. I now have Rudy and Jill's book to remind me of what little I have learned and need yet to learn. It is interesting and a great reference book.
I enjoy having this book and like everything about it except the name. It is not an apprentice...it is the master, the journeyman of anchoring. If you tend to be concerned even slightly when you drop the hook in a new anchorage have this book with you. If you want to know and understanding the skill and art of proper anchoring this is it. BUY THIS BOOK NOW and sleep well with your anchor down.
