No – they were wise. I have worked on a boat with no ground system that was hit. Step one was to get salvage divers to inflate airbags inside the boat and get it back up to the surface! Joe Coquina

My boat has been hit by lightning twice--mast was grounded to keel bolt. Most of my electronics were fried each time. So, if anyone claims that grounding works, I think they have been more lucky than wise.

This is vastly better than nothing. If you really want to get into it, you would need to tie in all the rigging and provide exit terminals at the water line. This website will give you some ideas: http://marinelightning.com/Siedarc.htm . If you want to be cheap, do what we did dating back to the 1960s at least - buy jumper cables and pull them apart to make 2 separate cables. Clamp one on each upper shroud and hang the other end in the water.

I have a 1976 30mki and we got caught out in a very fast-moving t-storm this weekend and I realized I should have done this when I bought the boat last fall. My mast step is not original. It is a big, fat piece of mahogany - which I envision blasting apart if the mast took a direct strike. The only idea I've had is using a steel ring clamp to attach a terminal on a very large gauge wire (maybe 2 gauge?) to the bottom of the mast, then run this wire a foot or two aft and down into the bilge to a keel bolt where I would have a second ring clamp hold the wire's terminal to a keel bolt. I worry about how this would look and I also worry whether it would even be effective. Anyone have a better solution? Thanks in advance. Hope you're all having a wonderful sailing summer.
