THE BOAT ELECTRICS BIBLE
Subtitled ‘A practical guide to repairs, installations and maintenance’, this book might appear from the cover photo to be aimed at the seagoing cruiser market, but much of the content applies to any kind of boat with on-board electrical systems. Starting with the very basics (what are voltage, current, resistance and power – and how are they related?) the book runs through AC & DC, taking measurements with a meter, batteries, tools, safety and testing. The remaining pages cover many of the tasks involved in maintaining and modifying marine installations including regulating multiple sources, installing shore power, engine monitoring, isolation, invertors, adding new equipment, and a few appliances you won’t see on many narrowboats – anyone for underwater lights or radar?

Over in Canada, they’re worried about ice in the Rideau Canal. But why? Don’t they usually get ice in the winter? Yes, they do – and that’s the problem: there isn’t enough of it! Every year, the canal turns into the Rideau Canal Skateway, the world’s longest ice rink – but this year, it hasn’t been cold enough and, as we went to press, it still hadn’t opened to skaters.
Meanwhile, Venice is having problems, too. Is it disappearing beneath the waters? No, the opposite: it’s been so dry that the canal levels have dropped by over 2ft and the gondolas are in danger of going aground! Perhaps we should send them some of our spare water…
