This manual takes both novice and experienced boatowners through minor and major repairs of electrical systems, engines, electronics, steering systems, generators, pumps, cookers, spares and rigging. When it was first published in 1990, this book broke new ground.  It was hailed as the first truly DIY manual for boatowners and has sold in its thousands ever since.  

There have been significant changes in boat systems since then, particularly electrical systems, and this edition has been fully updated to reflect these developments.

Nigel Calder, a diesel mechanic for almost 30 years, is also the author of numerous articles for nautical magazines and other books - all of which have helped tens of thousands of boatowners deal with mechanical problems at sea.
