I don’t believe 8 gauge has a chance of “conducting” a strike to ground!
And, if it did, I wouldn’t want it to disintegrate a seacock - they are
below water line, right?

David - Welcome to the Pilothouse 39 club! I bought my '84 several
years ago and love it. Raced it in Great Chesapeake Schooner Race
past two years.

Pulled the mainmast this winter. I also have those cracks around the
gooseneck collar. Not worried yet - Grinding and filling sounds like
a good idea if not water logged.
My mast was moving port to starboard on its ‘tophat’ step. So I
added a bit of wall thickness with epoxy and tape to inside of mast.
I also rewired with both pipe insulation and 100’s of wire ties left
long to keep wire slapping to a minimum.
Will use spartite this spring. Check your mast steps when you pull
your masts. The Two bolts may be quite loose. Mine were. (FYI mine
was also labeled as a F-44 mast step).

Not sure about your 20 foot up bulge – you may be able to see
inside
the mast with a powerful spotlight once it’s down and wires are
out.

I also agonized over the lightening strike issue. After lots of
research will go back to the 8 gauge green wire led to a seacock.
The boat is 22 years with no strikes yet!

Some masts were left bare. Mine, like yours, are painted/coated –
no
idea with what. In very good shape, I just waxed mine.

Hello Freedomers:

Just bought a 39 Pilothouse. Questions on the masts:

  1. They seem good, but is there any preventive maintenance or
    such to
    be considered??

  2. The mizzen (larger) mast has two very small cracks running
    around
    in a circle exactly where the large “goosneck” collar is joined to
    the
    mast. As a result, water has crept in the top crack, saturated the
    collar area (is it a huge stainless sleeve section in there that
    has
    the boom fitting welded to it???), and small watery rust stains are
    out of the bottom. This is pretty minor looking (or is it), so I
    am
    not that worried, but does anyone think it advisable to grind out
    those cracks (especially the top one), fill with very fine tape and
    epoxy, and sand back down??? I thought about a bead of 5200, and
    may
    do that, but I am not sure if it would look good??

  3. There is a somewhat strange “buldge” in that same mast about 20
    feet up running around the mast, almost like the mast had been
    sectioned together there. It is minor–cannot see at deck level–
    but
    I did notice it when I went up to inspect. Any ideas??

  4. Anyway to mitigate possiblility of lightning strikes??

  5. I may pull the sticks to transport the boat. Any ideas? If I
    do,
    I would probably refinish and repaint. Any experience with paints
    on
    fibre?? And–by the way–what is on there now, gel-coat???

Thanks,

David Wysen
