 I've got the grounding cable as well, but it only goes from the metal "shoe" 
that holds the mast butt to the keel bolt.  Nothing up the mast.RonWild

Re: Stus-List Mast Wire Question

[Mark McMenamy via CnC-List]

I have something like that on my 77’ 25.  It runs down the mast (I believe) and 
forward in the cabin to the bow where it runs down into the bilge.  It’s been a 
while since I looked at it, but that’s what my memory is.   It’s a thick black 
wire.

Subject: Stus-List Mast Wire Question

I have the mast of my C&C 30 MK1 down for rebuild right now.  Just replaced the 
wiring and found a cable I’m not sure about.  It is a heavy gauge stranded 
single conductor wire, maybe 1/8 or 3/16, with a thick red insulation on it.  
If I had to guess, a heavy ground wire.  There is about 20 feet of cable coiled 
at the base of the mast and it goes all the way to the top of the mast, where 
it just sticks out 6 or 12 inches.

Did these boats have lightning rods or something originally?  Is there 
something that a big ground wire would do that a 45 foot hunk of aluminum 
wouldn’t do?  I’m afraid to ask this one, as it is probably a religious 
argument, but should the mast (or a lightning rod??) be grounded to a keel bolt 
or something?  If there is supposed to be a lightning rod, does anybody have a 
picture of one and how it is mounted?

Thanks,
Steve

Re: Stus-List Mast Wire Question

[Bill via CnC-List]

I'm guessing it's probably for a lightning rod. mine's got a whopping wire going up in it, and a great big copper pointy stick. Maybe the thinking is that it would carry the juice down The wire and into the keel & out, rather than frying all of the instruments and everything else. But I don't profess to know all of this electrical stuff much less lightning strikes, but apparently somebody thought it was worth while, so I left it there.Bill On Mar 11, 2019 2:44 PM, Josh Muckley via CnC-List  wrote:I bet the PO had a "great" idea to put a wind generator on the masthead.  They used the mast as the ground and the red wire as power.  It explains the color, the gauge, and the length of both of the tail ends.Josh MuckleyS/V Sea Hawk 1989 C&C 37+Solomons, MD On Sun, Mar 10, 2019, 11:15 PM Steven A.

I bet the PO had a "great" idea to put a wind generator on the masthead.
They used the mast as the ground and the red wire as power.  It explains
the color, the gauge, and the length of both of the tail ends.

Given heavy-gauge single-conductor, I’d guess grounding cable for lightning 
protection.  I wonder what the PO did with the 20 feet of cable at the base.

Grenadine has a short AWG 0 gauge battery cable bolted to the mast box on one 
end and a keel bolt on the other end.  No such long cable in the mast.

Re: Stus-List Mast Wire Question

[T power via CnC-List]

That is interesting. I have a 30 MKI and there is no "Ground" or bonding wire 
up the mast. I'm under the impression the mast will bond with the step. On my 
mast step there is a provision for a bolt that connects to my bonding set up.

Could it be for something like SSB?
