Think even on a bone dry deck any salt particles even dried residue would still conduct the leckky through a person .

If lightning strikes the boat, the shortest route to earth isn't going to be through a person, unless he's dangling his leg over the side. If it strikes the person, that's another matter. Just make sure you're not the highest point on the boat. Wot you need is a nice big lightning conductor "A" frame

Wot you need is a Faraday cage. A cabin ali rib would fit the bill nicely.

Has anyone thought of asking the coastguard or similar if anyone has been hit by lightning in a small boat?
If not, you are probably OK.

Just a thought.

Being all technical. Isn't there a positive charge that emanates upwards from the earth that on meeting a negative one from the heavens enables the electrical current earth out? If so, you just try to eliminate the upward charge. If your RIB is a poor insulator then your chances of being hit are much less.

Lightning strikes on "small" boats DO happen. I suspect much more common in other parts of the world than UK though. Add to that the liklihood of being out in such weather and that ribs are probably less likely to get hit than yachts and its certainly not something I worry about.

IIRC it depends on the type of lightning?

Yes. When I've seen lightning hitting the sea near me, I've become very conscious of the fact that I'm sitting astride eighty litres of petrol.

That's always focussed my mind and I've run like hell, WOT, in the other direction.

A wet fibreglass boat will not insulate you from any lightning strike.

Lighting can strike many miles from the storm cloud.

Maybe Poly is correct by suggesting hanging a chain from the A frame into the sea. Better than nothing
