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
