How worried should I be about my boat being struck by lightning? I know it happens all of the time, and boats should be grounded (so don’t hold onto metal in a storm), but how do I confirm my 50 year old boat is properly grounded (my engine and hull zincs all last for over a year (but I change them regularly)). Do these zincs tell anything with grounded for lightning? Summer storms have been popping up a lot in Maryland these last few weeks, so I’ve frequently been cutting my days short to be extra cautious. I will absolutely always do my best to avoid being out in a storm, I just am looking for advice on how to check my grounding system.

Not really sure of the proper answer, I think this was discussed many years ago. In our marina we are under roof, if not there I prefer to be near to a sailboat, failing that any taller boat will do.
I'm not sure of a direct hit, but I've been lit up by a strike about 200 yards off the stern. Got one hell of a jolt thru steering wheel. Had a close strike (I was not there) where I lost all my equipment, 2 FM radios, 2 depth finders and 2 VHF radios. No other damage was found. The GPS was a combo with depth finder, the GPS still worked but depth would not. What I've heard is a very heavy gauge wire from a projecting metal object (anchor light?) to ground plate or equivalent. Dave
