Reddit mentions of Boatowners Mechanical and Electrical Manual 4/E

Sometimes it does nothing, sometimes it sinks the boat. Electricity of that magnitude is very unpredictable.

Some boats have lightning grounding systems, and do tend to fare better.

I highly recommend the Boatowner's Mechanical and Electrical Manual, which includes a section on lightning protection systems.

Boatowner's Mechanical and Electrical Manual is highly recommended(and currently on sale).

I've seen this one recommended a lot https://www.amazon.com/Boatowners-Mechanical-Electrical-Manual-Calder/dp/0071790330/ref=pd_cp_14_2?_encoding=UTF8&pd_rd_i=0071790330&pd_rd_r=1HPP9SJME5RFS1C0671Q&pd_rd_w=dtry3&pd_rd_wg=BcuIJ&psc=1&refRID=1HPP9SJME5RFS1C0671Q

Also, buy this book,

Boat repair and maintenance is not hard -- but there is a lot of specialized knowledge. YouTube and forums are great resources -- but they are not a replacement for a well written, comprehensive book. You need all three sources!
