When big T-Storms come through in the BVI we turn all main power breakers off. Something I was taught when crewing on superyachts in another lifetime.
We also do this on our own yacht which has a lightning protection system...just in case.
...anyone know if this is nonsense or...a good call?
Turning off the breakers is helpful if you don’t get a direct hit.
Most times the lightening strikes close enough to cause a light stray current to enter your system where it will fry the radio or some lights and not effect anything else and that’s when turning off the breaker box helps
