pmichaelis is on a distinguished road
There are numerous folk medicine cures, but none that are 100% effective. My boat had a well grounded system and was struck by lightening anyway. The strike evaporated my masthead antenna right down to the loading coil, then proceeded down the standing rigging and out the hull mounted grounding plate. The total damage was; the antenna, the masthead tricolor strobe unit and the voltage regulator on the engine generator. Afterwards I added a copper plate attached to a substantial braided conductor which had a very large battery clamp attached. This was clamped to the backstay whenever the boat was on it's mooring or when I was aboard and saw an oncoming storm. As a physicist, my recommendation is to avoid changes in the path of your grounding system. Any deviations represent an increase in inductance and since the voltage developed is L(inductance)x(Di/dt), with Di being very large and the time period dt very short for a stroke of lightening, the backvoltage developed can be enormous and divert the energy to another path.
