I used the wrong terminology when I was speaking about antenna system grounding on a boat. What I actually meant was a counterpoise system. I agree that a vertical dipole works well but would be difficult to install permanently on a small boat. A vertical is most often used with a tuner. There are standard mounts and they are pretty easy to install and are sturdy and well suited for marine use. I also agree that all structures should be bonded to the counterpoise system. Some of the boat builders(Hatteras ,Bertram .etc) would put copper screen into the fiberglass layups of the flying bridge decks and roofs with a stud connected to it so that it could be tied into the system. On commercial trawlers the antenna would be mounted on the mast about 30 or 35 ft above the water.It was fed with a wire about 25 or 30 ft long so it was actually a 55 or 60 ft end-fed. With the outriggers lowered and acting as radials, the trawl doors and cables in the water and everything else bonded together, it is a pretty good counterpoise system.
