Many Sportfishermen in the Fl Panhandle have ground plates that they connect to their tuna towers, which are of course pretty similar to a radio mast
but made from aluminum
I think Dynaplates are often used just because they are available is all, most of these are fitted by yards, who will of course use off the shelf components.
Difference is people sit in those towers.
Iíve never heard of anyone being electrocuted sitting in a tuna tower or fly bridge, but have heard of boats sunk from the grounding plate being blown off, leaving a rather large hole in the boat
I have no idea if 99% of boats are protected with a grounding plate and only 1% get it blown off or if itís the other way around.
Iíve come to believe that lightening is I guess similar to a tornado, very unlikely, but also no real way to protect from it, if your hit, most likely there will be damage, that you canít prevent.
Maybe thatís a defeatist attitude, I donít know, but surely if something worked there would be Insurence breaks if you had it?
But buildings are protected, so why canít boats be similarly protected? Is it the grounding point that is the difference?
I used to hang some SS chain from my chainplates in the water
, but just quit.
