There are not that many vendors that specialize in fabricating marine ground plates for lightning protection, which makes me think that perhaps a basic copper bar (which is readiliy available) will be adequate. The only available 'specialized' product I have been able to find is electroplated to guard against corrosion, and is quite expensive ($500).
My own opinion is that if you are in an area where lightning is prevalent, you should ground your boat, which I am planning to do this winter when mine is hauled. I'd like anyone's feedback on what should be used as the plate (and dynaplate is not an option due to it's porosity). I understand the charge is dissapated via the edges of the plate, so a long, narrow bar is ideal since it has more edge surface area than a square plate. I also understand the principle of bonding all major metal components together to equalize voltages and minimize the risk of sideflash, and that the main conductor and all bonding conductors should be 4AWG minimum.
What material should I use for the plate itself? Does anyone have a preferred vendor for a particular alloy and/or electroplated product?
Thanks.
