G'Day Chuck,

If there are no such records then two of us had a fair chance of making one
yesterday if we hadn't got off the water.

At the storms peak, which lasted half an hour in our location, there were
about 5 strikes a minute, with no time between some of the flashes and
thunder that I could measure. This was a hell of a storm - with hail larger
than golf balls in some places - lot of damage. I was using a carbon fibre
paddle.

Kayaks are insulators coated with a conductor, water. Not only that but
humans are good conductor being mainly composed of salty water. And of
course there are carbon fibre paddles! Michael Daly recently measured one as
having a resistance of roughly 40 Ohms and Dave Kruger also gave a
compelling description of the behaviour of materials in a lightning strike
(Paddlewise Digest 2096).

Some times a calculated risk degenerates into a "drunkards walk" gamble.

All the best, PeterO
