Warm Weather Sailor
When caught in an electrical storm I now resort to prayer. Having been hit once when 100 miles from my destination I've come to realize that there's nothing you can do. Note your position if within vhf distance to shore and pray. Put your handheld in the oven or on deck with you. As for bonding, not bonding, bottle washers on the masthead etc., etc., they don't do anything. My boat's through hulls were not bonded but when we hauled after the strike there was "treeing" (burn marks in the paint) at all the through hulls and at the gudgeon and pintle of the rudder. I think the good thing about my strike was that I have a wing keel (Hydrokeel) with a very large surface area which was good for dissipating the charge and the keel had a strap to the keel-stepped mast. As for jumper cables to the shrouds it might make you feel better but that's about all. There is a lot of literature on this subject and I read most of it after I was struck, that's why I pray now. Nothing else will do it!!
