alot of pro boats (trawl, longline, short line, trappers) out in almost all conditions and for the bigger boats of the fishing fleets they may be out way too far to even worrie about things like storms and squalls
i can't say i have heard of any of them being hit by lighting and they have some very big and long arial for the radios on board that would make great lighting rods
why this is i can't say nor can i say why you don't hear of boats being hit even if they are moored boats
i have also been on rock walls fishing for jewies when lighting storms have rolled over and i have yet to be hit and would say i'm more of a chance of winning the jackpot lotto or being hit by a car while going to work than lighting
but boy do the fish really turn it on when storm frounts close in
