Or even a wide copper strip down the inside of the daggerboard trunk. That would be easier. That could be connected to a sheet of copper glued to the outside of the hull.

Boat... Personally, i think i would stay in the forward part of the rear berth. Farthest area away from chainplates and rigging, that i can tell anyway. Also not on top of any wiring, at least in my boat. And not directly under the mast. I suspect i would lay there with the admiral praying that we don't get hit by lightning.BOAT wrote:Just curious, if you had to be inside the boat when it got hit where in the boat would you have liked to have been? What did things look like on the inside?
Yup, that's what I was thinking too - I always thought I would cower in the aft bunk under my blankets in a lighting storm.vizwhiz wrote:Boat...

From the inside of the boat you couldn't tell anything had happened, except for the exact spot where the lightning passed through the hull. There was a circle of white inside about three inches in diameter where the fiberglass had delaminated. When i ground it out, the inner layers were black and appeared charred, but everything was still intact. The rest of the interior was just as dirty as i had left it!![]()
I ground only a small amount of the interior off in order to leave the main layers of heavy weave intact as much as possible. I didn't grind all the way through the exterior. I left it continuous so i could lay up a few layers inside for strength, then ground down from the outside to repai. Again, the hole itself was really small, and the charred area was also very small. I didn't want to take off any more than necessary to repair the hole since this was below the waterline.
