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.

Beats me, my 1980 version has nothing like that. Just wiring to the wind 
instrument and VHF antenna at the top. Lower down, there’s wiring for the 
steaming light/deck light combination.

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
