Lightning Strike Protection for Sailboats
When at sea at night and the lightning is erupting all around your sailboat you feel extremely fragile and exposed. The dread of the lightning actually striking your boat is very real with the possible results not something you wish to contemplate when you are on passage in the middle of an ocean. The grounding system must conduct the current to a point of contact with the water. A lead keel is adequate, and it may be painted. The conductor must be bolted onto the keel in some place that is reasonably dry and where it can be inspected from time to time. Alternatively a grounding plate with a surface area of about 1000cm² can be fitted. This must be separate to any HF radio grounding plates.
