There is no reason you can't use an unencapsulated metal keel for a ground in a lightning protection system. If the keel is encapsulated, then you will have a problem if you do so...but with an unencapsulated keel, it should be fine.

I'd second reading the website that CruisingDad pointed out... it is very comprehensive and detailed.


Brezzin-

If the compression post was stainless steel, then your grounding system was probably inadequate as a lightning protection system. Stainless steel has a fairly high electrical resistance, which is also why you shouldn't use stainless steel washers in your electrical setup.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
