RE: Is your trawler sinking?

I have not had the same experience with thruster zincs. They seem to last the same length of time as all the rest. I change them once a year, with quite a bit of life remaining. You might check with a local marine electrician as to what's going on there. I use a "B" bullet shaped shaft end zinc.
