To obtain capacitance coupling to the ocean the plate has only to be
below the external water line and I have not seen too many boats with
bilge water that high.

Further if the plate is only acting as the ground plane in an antenna
system then to avoid electrolyses the RF ground should be connected to
the plate through high voltage capacitors thus no DC current on the
plate.

If connections are made with proper tin plated wire and terminals
there is no reason that corrosion should be any more a problem then
with any other electrical systems mounted below the cabin sole.

If the "Plate" is to used to be one side of a Capacative Coupling
for the RF Grounding of an MF/HF Antenna System, then your "Best
Solution" is to use a material with the Lowest Resistance, Highest
Surface Area, encase it in the Thinest Dielectric Insulating
Film available, and mount it as close as possible to the SeaWater.
No High Voltage Capacitor, required, as the Dielectric Film will
be the DC Current Insulator.
