This Old Boat book cover This Old Boat by Don Casey

Subtitled "turn a rundown fiberglass boat into a first-class yacht on a shoestring budget," this book is the best introduction I know boat maintenance for the new or prospective owner of a "modern classic" sailboat. Starting with guidelines for selecting a boat, Casey proceeds to fiberglass repairs, cabin and deckwork, spars and rigging, boat equipment, woodwork, electrical, plumbing, refrigeration, painting, canvas work and sails. All of this is described in clear, simple terms perfect for the inexperienced. This is the book that taught me fiberglass work. But don't let it fool you; this book is appropriate for experienced boatowners, too. I still refer to it.
