Hello, I just removed the fuel tank
from my Union and am replacing it with three aluminum tanks
to keep the same gallons, and be able to put them back in the boat. Original tank was built arount the fuel
and water tanks
So I had ot spend 4 hrs using a sawzall to remove it.
By doing this it allows me several advantages using 3 tanks. Don't have to keep a full tank (90 gallons) to keep oxidization down. Can carry as little as one tank full (30 gallons) for coastal cruising with the other two in reserve for offshore
cruising. Can isolate new fuel
taken on in different ports
, and if dirty can run it through my dual racor
filter system to clean it up before using it. And finally and most important to get them in they have to go back in a sort of jigsaw puzzle manner. So 3 was the magic number.
After removing the tank I cut a 4"X4" hole in the fiberglass
floor below the tank and the 7800 lb. Cast Iron keel
was directly below and completely accessable for taping a 5/16 bolt into it and connecting a couple of 2" copper foil leads to the SSB
transmitter as a ground and a second to the tuner as a counterpoise
. This also needs to be isolated from any other grounding system on your boat (DC, AC, and Lightning).
Question: (finally) has anyone had any experience in using a full keel
(cast iron or lead) as a RF ground/counterpoise? How did it work? What kind of SSB
are you using? Are you also a ham operator? I am call sign is K1JRL.
To any Union Polaris owners or would be owners I gave set up a website specifically for UnionPolaris 36ers. Just google
Look forward to some feed back if you can.
