Galvanic Isolator

[colburnp]

I'm a new owner of a 29 Tug. After a little more than two weeks in the water in her slip near St. Petersburg, Fl the zincs had an unusual amount of wear for such a short period of time. She is at the yard, on the hard, for her inaugural bottom job. While we have yet to check the power situation at the dock (that will be done before she comes home) both the yard manager and my all-around mechanic urged me to contact the factory with two questions.

1. Is the rudder bonded? I didn't look when the boat was here and she is now on the hard. I know there is no zinc on the rudder as we have had in previous big trawlers, but we don't want to have too many zincs on either. She will live in salt water full time.

2. Is there a galvanic isolator on the boat (2910)? I haven't seen one nor is there any literature indicating the presence of one. Do you think the addition of a galvanic isolator would be in her best interest? An ounce of prevention, etc. I've looked on the forum and I believe the answer to this question is no.

Hello Colburnp,

If you could sent me your entire hull number I can check and see if we installed a galvanic isolator on your boat. You can send it in a PM if you'd like. To answer your other question, yes your rudder is bonded.

Thanks,
-Kenny
