the bit about water being a good conductor......this is basic stuff,
but if lightning strikes the water will it kill all the fish for miles
around the point of strike

seawater is a good conductor. Therefore with the boat upright you have a long pointed mast attached to an efficient earth. If you capsize the boat you no longer have a conductor pointing skywards. There are two risks from electricity the first is that current flows through your body. If you are swimming in a good conductor your body is unlikely to be the path of least resistance to Earth is not through you. The second is if you are close to the point of energy discharge where you might suffer burns from the flash or be showered with debris if something like a mast explodes.
While I don't know what the impact on fish would be I would only expect those very close to the point of the strike and near the surface to be affected. |

But we are also made mostly from salty water, so we are quite good conductors too. I agree capsizing will greatly reduce the chance of a strike, but I still think if you are unlucky enough to be in the area of a major strike, you are toast. |

how does a carbon mast with metal wings sound, get exploding red hot carbon splinters and your standing on a highly conductive bar. Perfect.

Hmm I'm not sure if hydro would go in such extremes to be in the Picture of the Week topic!

Fancy a sail at night, off the Atlantic coast?
You'll see more awesome pix on http://ppfeyte.free.fr/orages/storm3.html. Anyway, I thought there were grounding devices made for sailing boats and yachts. Are they any good?
