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 UnionPlaris.
Look forward to some feed back if you can.
Thank you,
Jim
