as far as i am aware you should be fine if the boat is struck by lightning, as the lightning should hit the mast and travel through the path of least resistance (that would be the boat and in to the water), or basically the boat means that you are earthed. However if you have a carbon mast, i believe that they can explode whan hit by lightning.
Never, under any circumstances, take a sleeping pill and a laxative on the same night.

There was an instance in Australia last year when a Laser was struck by lightning and the poor guy was blown out of the boat. Blew him about 30ft, holed and delaminated the boat.

Unless you are in a Faraday cage, you can get hurt by lightning.

I was once told by a sailor in florida that you need to soak a piece of rope in the water and tie it round the mast at deck level, then put the other end directly in the sea. This apparently provides an adequate conductor for the electricity, and will save the boat and crew from too much damage.

So how many times had he been struck by lightning in order to test this theory?

If you are a boat when a big bolt strikes directly, you are going to be fried whatever you do. Lightening strikes of up to 280,000 amps and 80 million volts have been recorded. 280,000 amps is going to explode anything in it's path. Minor strikes are survivable; big ones aren't. It's a lottery.

What!!! Water conducts electricity very well!! You're best staying in the boat, not touching anything conductive (i.e. metal) and hoping the strike isn't very big...

Stefan's right, any major hit will explode most insulators - which is why you shouldn't stand near a tree in a thunder storm, cos it'll explode!!
