Lightning ground

However, this cannot be used underway because it would trail in the water. I do not want to attach the sheet directly to the hull because of my fears of 10E12 watts being disspiated against my hull in 50 microseconds. However, why not wrap the sheet around the rudder and use the ground braid to attach it to the backstay? This would give plenty of surface area and keep it away from the hull. A strike might disable my rudder but I have a backup rudder I could use. I'm not sure I want to lose a rudder, even if the lightning didn't fry me as it came past. ;-) Attaching a straight run from the mast to keel is a usual first step. The plates are suspenders. If a thunderstorm comes up, I'd stop, strike the sails, put the plate(s) overboard, and go below. I hear reccomendations that ppl stay inside for 20 minutes after they hear the last thunder. If we did that, we would never go outside in the summer herre in N. FL. |
