The main thing for good xmission is good counterpoise.

I don't think David (OP) is going to have a counterpoise problem, his boat
being steel hull. I think his problem is going to be the lead from the tuner
to the insulated backstay (6ft above the deck).

Myself, I have no external ballast and all through hulls are non-metalic..
I'm using a 3" foil strips in the bilge and my SWR is very good (I don't
remember the exact ratio).
