Hi Bill,

A couple of things to check too - make sure the mast is grounded - not to battery 0volts but to a decent ground and use flat copper strip to ground it, this works best in cases where there is a lot of local static caused by lightning. Also make sure toe rails, stanchions etc are all similarly grounded too and this will improve protection. Bear in mind though that mother nature is so powerful, that there is very little than can be done to completely protect the boat, but grounding as suggested will help.

ESD (Electro static Discharge) is a complex subject and many books and conflicting opinions are written about it, the suggestions above are made on experience gathered over the years of supporting cruisers worldwide.

kind regards
Derek
