This book is part of the fernhurst Essential Boat series, following that established format with good illustration and the use of colour throughout. Pat Manley has tested electrical devices for Practical boat owner magazine and has an extensive practical knowledge of marine electrical equipment. Electrics are one of life’s mysteries to many sailors and there continues to be a belief that water and electricity do not mix. The author has done a good job of dispelling the myths and provided a very simple to follow guide to the basic skills and tools required to correctly install, maintain and troubleshoot electrical equipment afloat. Equally valuable is his review of solar panels and batteries as part of the task of choosing the most suitable products. The high quality of colour illustration greatly helps to present a potentially technical subject in an easy to understand manner. An invaluable guide for all sailors.
