Lightning

[RPZ]

Thanks for all the responses. I'm beginning to draw some conclusions, albeit not written in stone.

A copper projection extending above the mast with an attached insulated heavy gauge copper strap or cable that runs down the mast, at the bottom to which the same type of line could be attached and trailed over the side into the water.

Additionally, when docked or moored have insulated copper lines that could be attached to rigging and simply played over the sides into the water.

Interesting subject. My closest encounter with a lightning bolt was at about 20 yards. Was looking out a 2nd floor house open window, after a rainstorm. No wind. Kaboom! It struck the middle of the street in front of the house.

Scariest times have been up on the mountains carrying all kinds of metal climbing gear, hammer, ice axe etc with lightning flying around.
