Mark, I too am afraid of lightning--while being fascinated by it. And I've flown through hundreds of storms as a commercial pilot, and hope to live to see hundreds more in bluewater situations. I hadn't seen the Zzapstraps--and don't expect I'll put something that heavy/unattractive on my boat. I feel bad enough about all the 1/0 and 2/0 cable I'm installing to connect my battery bank!
I'm still thinking this through... It may come down to my comfort level with leaving six square feet of grounded lead keel exposed in a marina where everybody is hooked to shore power. And I need to do more research on electrolysis first.
Thanks for this info!
David Shaddock
