Next message: Lee Haefele: "Re: lv-ab: SSB Ground plane"
IMHO, if you are a salt water cruising boat, I would simply use some grounding braid like you can purchase from a ham radio outfit like Amatuer Electronic Suppy and run the ground braid from the grounding post of both the transciever and the tuner directly to the closest thru-hull (provided that the thru-hull is bronze). I even ground my vertical antenna (hf antenna - hustler vertical with screw on resonators) directly to the rudder post. The long wire (backstay) does not need grounding.
This set up works very well in saltwater and even brackish water. Standing wave ratio (SWR) is tuned by the tuner to a very acceptable level.
On a previous boat, we used copper screen that was lining the hull and grounded to a thru-hull, but the performance was not noticably better.
