THE BOAT ELECTRICS BI­BLE

Canal Boat - - News -

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…
