PS Here's a thought... The reason winchmen don't grab the strop immediately from a helicopter is they prefer to let the strop earth the static energy generated in the rotors/helicopter first. If Diver X grabs the strop in the water, it will earth through him. He will get a fair jolt apparently, but would he suffer the further indignity of his dry suit catching fire?
It's a good point, though there must be a very large difference in magnitude between the energy earthed in this way and the kind of spark you could generate from a suit!

If you've ever been zapped by a helicopter (I have - Chinook), it's not a nice experience. I have zapped myself with a piezo lighter - there's just no comparison :-)
