4321RE: [campernicholson] Lightning Protection

      Articles that I've read on the topic over the years  don't seem to have any real consensus on the topic.  Ground plates on the bottom of the hull seem to be common,  but other sources I've read say this isn't a good idea since lightening can leave a hole at the point of exit to the water.  These articles say that its better to run a heavy conductor either from a shroud or from the mast itself directly to the water.   In the situation like you described where you were caught out in a storm, you might consider carrying a something like a heavy duty car battery jumper cable to use as a temporary ground for your mast or shroud to the water.

      Subject: [campernicholson] Lightning Protection

      I am wondering what other Nicholson 35 owners have done for lightning
      protection. I have developed a keen interest in lighting protection
      after getting caught out on the Chesapeake in a thunderstorm last week
      and getting a mild electric shock at the helm while steering the boat.
      Quite a wake up call. I have hull number 132 and there is a small
      sintered bronze plate on the outside of the hull that is connected by #8
      wire to the mast.

      None of the shrouds, stays, lifelines, stanchions, or any other metal
      objects are grounded or otherwise connected to this plate

      I look forward to hearing what lightnting protection arrangements others
      have in place on their boats.
