Currently I own one carbon mast
, and two alumnium masts. I have also had an aluminium mast
struck by lightning
There is no question that if you get hit you could have substantial damage from a lightning
strike, but wether the mast itself is damaged is an open question. In our case the copper conductor took the brunt of the hit but everything electrical
was still fried on the boat. Had it been a carbon stick I am pretty sure that the same thing would have happened.
My basis for arguing that CF is no more likely that aluminium to suffer lightning damage is that insurance
companies don't charge different rates based on the material of the mast. They likely do charge for the price
of replacement, but not its construction. If there was a statistical difference in the damage likelihood between them it is the insurance
companies that would be the first indicators.
