I'm doing a page on my website, The Frugal Mariner entitled "Lightning and Your Boat."
During my research, I was curious about the efficacy of the Forespar Lightning Masterô(Static Dissipater). I couldn't find any statistics and so wrote the company. This was there reply:
The "study" is the fact that since the early 1990's we have sold about10,000 units worldwide. Of these we have had reported strikes totaling 4. Not bad empirical data. Of these strikes damage was minimal. Isolated to EMP induced damage rather than direct strike damage.
Even with this said, Forespar does not claim that this device is 100%
effective. No one can make that claim.
I have a friend whose boat was hit, in it's slip, between two other taller boats. His had a wooden mast. And a Static Dissipater. It seems to me the odds are against my knowing of one of only four in the world who have been hit and had a Static Dissipater. But there are coincidences.
I'd like to poll the Sailnet members.
Has your boat ever been hit with lightning?
Do you have a Forespar Lightning Masterô(Static Dissipater) installed?
Has you boat with a Forespar Lightning Masterô(Static Dissipater) ever been hit while the Static Dissipater was installed?
Not a very scientific survey, I'll admit, but neither is their "empirical evidence." I'm also contacting insurance companies to see if they have collected any information.
Thank you for your participation.
