I'm getting only about 5 mounths out of a set of zincs (1988 40' DC). I think I should be getting better than this. We relocated the boat to a temporary location in S.C. recently, and the problem persisted, so apparantly this is not a marina problem. A couple of years ago when I became concerned I had it tested by a surveyor with a background in electrolisis. He said the problem is not the boat. But it's begining to look like the problem may well be the onboard as we have been a transient lately.

Am I wrong to think that I should be getting more than 5 months out of a seto of zincs?

If not, anybody got an ideas what might be the primay culprit?

I have also heard that Hatteras is installing something on all new vessels to minimize this problem (but it's not a galvanic isolator)?

Thanks,
