This just went way over my head. If the capacitors are on parallel this means 4 connection points – two at each end? How is this connected to the single ground wire? Also, the boat ground is not used?

If you want to be on the safe side you can put 10 small ceramic capacitors with 3900pF (2500V) each, solded together in parallel (will give 39nF(2500 V) with little Skin Effect) between the tuner ground (ssb ground) and the boat ground. This will prevent any DC current (and will prevent electrolysis) but will give a solid HF AC connection.
