+x Sonia Johal - 22 Jun 2024Thanks for the info! That's very probably just as effetive and way cheaper! I think this is a topic where the true science is not well understood. Or at least there is no certain way to protect.NeilSV Midnight Sun IIILightening Protection Thanks Neil,I’m not sure of the brand you mentioned, but I discovered the famous sailing boat called the Maltese Falcon uses Forespar’s lightening dissipators.They look like an upside down metal loo brush on top of the mast… and available from UK chandlers such as Force4, they cost about ~ 🇬🇧 GBP£250 plus installation and cables.I’m not sure how effective they are, as I haven’t been struck by lightning, but I was advised to install a single unit at the very top of my 12m boat’s mast.Please do refer to the link attached;Fair winds,SoniaSY Salacia
