This is the owner's manual for the mechanically impaired sailor or powerboater. The simplest, least threatening guide to boat maintenance and repair ever written, "Know Your Boat" is dedicated to these propositions: that simply praying that nothing breaks on your boat doesn't prevent it from happening; that things don't often break when you're at the dock and help is convenient; that the things that go wrong are most often things you can solve; that you don't have to be a mechanical wizard to solve them; that solving problems yourself will give you more confidence in your seamanship and more satisfaction from your boating; that self-sufficiency is addictive and that reading about all of this ought to be fun!So take this tour of basic troubleshooting and repair procedures for your engine, electrical, plumbing, refrigeration, and steering systems, then grab your wrench and prepare to tame the savage beasts behind your boat's electrical panel and engine hatches - or at least make their acquaintance.
