I run an insulated SS wire from the masthead to the deck, through a vent direct to the antenna tuner. I used Dacron line to attach the wire to the deck and mast head,
Works well. (over 1000's of miles)
You could just attach the antenna to the rigging. On a GRP boat it would work OK in fair weather.

Subject: [world-cruising] SSB Antennas
I am installing an ICOM M700 SSB radio on my sailboat. I only
occasionally go offshore, so I would like a antenna setup that can be
dismantled when not in use, which will be most of the time, but can
easily raised when needed. I don't want to use the backstay for
several reasons, so I think my options boil down to using a 23 foot
whip antenna or a long wire strung somewhere on the boat. One person
told me that just using a 1/8 inch copper wire running from an
attachment on a shroud to the top of the mast would work just fine.
That strickes me as a good, and potentially low cost solution.
However, I'm stumped on what to do to get the wire around the
spreaders. If the antenna were attached to a shroud 6 feet above the
deck and to a block on the top of the mast, it would touch the
spreaders along its length. (I am assuming that touching the metal
spreader would interfere with the antenna's effectiveness.) My boat's
mast is about 40 feet high and has two sets of spreaders. I would
appreciate any suggestions anyone might have on how to solve this
priblem regarding the spreaders, or more generally, if there is
another way to use a long wire antenna on a sailboat, other than the
backstay.
Many thanks, Tim
