Do yourself a favor: if you own a boat, you should also own the Boatowner"s Mechanical & Electrical Manual. Written in a simple, accessible style, the Manual is aimed at helping the nonexpert solve problems in marine systems--think of it as a friendly mechanic. Author Nigel Calder explains how the systems work, helps you troubleshoot and identify problems, and presents clear and concise instructions on how to repair them. Best of all, Calder also offers helpful advice on how to prevent future system failure. Absolutely indispensable for boat owners. --M. Stein
