Quick question: is there any special procedure for sailling in a thunderstorm?
There's really not a lot you can do about it but pray. camaraderie's #1 and #2 suggestions are valid. (#3 is arguable--but let's not). Thing is: Lightning isn't going to strike your mast unless it was going to strike w/in a circle the radius of which is equal to the height of the mast, anyway. So, if you have, say, a 40' mast, you're only going to attract lightning for a 40' radius around you.saurav16 said:yeah motoring sounds like a plan but what about lighting?
Avoid it. If that's not possible, reef early and make sure the engine's ready. Make sure that you keep the bow (or the stern) facing the waves. Don't leave a lot of things loose in the cabin - especially in a small boat. If there are enough of them, and they are heavy enough, your boat may become unstable.

Yes, but if the keel, rudder or prop aren't connected directly to the mast, via a relatively heavy conductor, chances are very likely that the lightning will sideflash through the boat to get from one to the other. This is more the case with a deck-stepped mast, than a keel stepped mast, especially if the keel is bolted to the mast step.eherlihy said:According to Chapman: " A measure of lightning protection can be obtained using the principle of the "Faraday Cage." A high pointed conductor, heavily wired to all points of the boat, seems to cast a cone-shaped umbrella in which lightning does not strike. Instead, the voltage is conducted safely to "ground" in the water via submerged metal parts such as the rudder, sailboat keel, or propeller."
