[electricboats] question about lightning

Hi Folks,

This past season was the first one for me using my Pearson 10M but was a somewhat shorter one due to some health issues of my family members. I did get out several times and was able to begin using the system that the previous owner had put together which is a Thunderstruck with 4 Li Cells for 48V and 196Ah, I believe. My question is what measures any of you take during thunderstorms if you cannot be back to the marina or get off the boat. My boat has a mast that is keel stepped on a metal plate that is bolted into the metal portion of the keel. It would seem this is an adequate path for a lightning strike if it were to occur and that a reasonable approach if we have to be on the boat through a storm is to get into the forepeak and away from the mast and Li cells which are in the port quarter berth. Is there anything else that could be done aside from switching off the motor, path to cells, etc. Presumable the breakers/fuses on the mast electronics will blow to hopefully protect some of that.

 

Thanks,

Scott
