It seems that almost everyone uses a back stay as a ssb antenna....remember that steel, and even stainless steel is a very POOR conductor for RF>
Instead, run a separate wire from the back of the boat up to the top of the mast. Use this for you antenna, it is copper and is a GOOD conductor. Yes, the other wire affrect it, but they do the same thing with the backstay. PLUS...you can not solder copper to the stainless backstay, so you use some sort of clamping arrangement, and every few months get up there and renew everything.
Use a separate copper wire and never have to renew it.
I have been /mm for over 18 years now and have installed too many ssb transceivers to count. I always use a sep. wire for the ssb antenna. Just make sure that it is not in the arc of the swining boom.
While we are at it...remember a verticle diapole does not have to have a good ground.
The /mm verticle is equally poor in all directions, or at least almost equally poor. The fact that there is an ocean for a ground lets us work out fairly good. But just think, with the verticle half wave diapole....wow...look out dx. here we come.
