I had a phobia about lightning strikes and researched and researched the subject. No guarantees from manufacturers. Bottom line is IF. If you are out there when storms are forecast
or in season? If you get hit? If your hanging onto s/s rigging
etc etc? If your boats steel
, wood, plastic, Where's the current
go? Do I trail 100yds of chain/wire?
Heard of damage, particularly electronics
(hence the expense), but few if any, deaths on yachts from lightning. Though sadly I imagine it has occurred.
Also had an uncle struck. He was beach fishing
off Stockton Bight NSW, it struck the tip of his beach rod and blew his wellington (rubber) boots to pieces. He was out for a while and bad burns, but alive. Think of the wellington boots as your keel? I did and am over my phobia. Weather
reports and / or a radar
might be a better avoidance of elec storms than 300 lb of extra metal onboard? I really don't know.
Don't take this the wrong way, not being a smart arse, the above is exactly as I went through. I still have a little bit (phobia) left and park between bigger boats when not on board.
Hope you find what you're looking for and let me know if it works.
