Lightening strikes & Earthing your boat?

Can someone shed light on the best system of insulation for lightening strikes? What/which is the safest method?

There are some other threads on here about this, but essentially you don't want to insulate against the strike, you want to provide an absolutely wonderful path for it to go from the top of your mast to the water. Otherwise, it picks its own path. Metal (copper?) plate in the water, and small gauge wire going to the mast head, with a lightning fuzzy up top.

There's numerous lightning threads on the CruisersForum.
Try a Google search:
lightning site:www.cruisersforum.com

My search returned about 291 results from www.cruisersforum.com for lightning.

Thanks for responding, I hadn't realised there was a thread on the subject of lightning strikes and have since checked it out - very interesting indeed.
