Ask Maine Sail. Basically, LIGHTNING DOES WHAT IT WANTS..
. anything you do to try and change its behavior is mainly wishful thinking and will make you feel better, but really not help at all.
Yep we have over 1200 boats in our mooring field and perhaps 90-95% of them are sailboats. Most are 30' or bigger. The same day my boat was hit a teeny tiny Cal 22 was also hit and had holes blown through it. It had one of the shortests masts in the mooring field and perhaps the most minimal or "systems" and was in a cluster of boats all over 30' whose masts were significantly taller. My boat neighbor to one side has a mast 8 feet taller than me and the other closest guy has one 10 feet taller. The guy behind me with the "lighning attractor" has a mast 2' shorter than me and was still hit. My spar is properly grounded yet my mast was not hit and my boat took and indirect hit through the ground side of the system.
My friend Kim's boat, a large racer with Carbon spar and fuzzy attractor, was also hit and the spar had to be sent out for a full inspection and repair (DO NOT GET HIT WITH A CARBON SPAR $$$$$$$$!). Lightning does what it wants to.
The only believers in "bottle brushes", "fuzzy disipators" or "lightning attractors" are those who have not YET been hit. They ALWAYS believe they have not been hit because of it UNTIL they get hit. At that point they may or may not realize it is junk science based in nothing but unproven theory.
Lightning will hit what it wants, when it wants to, snake oil devices or not..
Oh and NONE of my fuses blew. The lightning came though the ground side and the voltage is so high it often completely ignores fuses and jumps across them before blowing them. My boat was the fourth one it two weeks the surveyor had inspected due to lightning. All were different but most all had virtually no blown fuses. I have seen lightning blow a seacock off a thru-hull and vaporize bilge water enough to blow the cabin sole boards off the bilge.
The ONLY science that I see working for lightning strikes is the science of adequate INSURANCE coverage!!!!!!!

Even with this said, Forespar does not claim that this device is 100%
effective. No one can make that claim.
Consider that the Boat US foundation puts your odds of getting hit at 1.2 per 1000 that make it 12 per 10,000 Forespar is claiming 4 per 10,000. This means the devices barely work if you even trust what Forespar is saying. We can also guess that there were also some hits on boats where they owner never knew who made the dissipator because it was on the boat when they bough it.. How could you report it to Forespar if you did not know who made it. Food for thought and more food for my opinion of them as "junk science"..!
From Boat US:
"You Can Run, But You Can’t Hide
Volumes have been written about methods to mitigate damage or even avert a lightning strike. Lightning, however, doesn’t seem to read them. As an example, one boat, fitted with a popular “fuzzy” static dissipater at the top of the mast was struck twice in one year; ironically, the second time the bolt hit the dissipater even though the VHF antenna right next to it was higher (claim #0308082)."
