    Bill,

    Are you planning to sail to an area where lightning strikes are extremely common? I spent quite a bit of time in the waters inside Vancouver Island, and can't remember any particularly bad thunderstorms. Grounding the mast wouldn't even get onto the bottom of my personal priority list.

    Hi All

    Just wondering if copper pipe would work for mast grounding?

    I'm designing a two piece telescoping mast and am playing with the idea of having a 1/2"/13mm copper pipe in the lower section and a 3/4 / 19mm copper pipe in the upper section so they can telescope when the mast sections do.
    I can't see any way of making a cable work which just leaves tacking copper flashing to the inside of the lower mast section and outside of the upper mast section and hope they're make enough contact to carry the load at the moment the lightning hits.

    Hmm, maybe I should be looking at an aluminum mast...
