No particular reason other than I like to do it that way. And I can tell you from 21 years and 25,000 service events experience that it makes absolutely no difference where on the shaft the anodes are located, from a protection point of view.

I don't know but I would assume so. Boatyards will typically replace all anodes during a haulout, regardless of their condition.

Assuming those anodes were only 3 months old, that would be pretty rapid depletion.

You are also experiencing rapid depletion. Everything being as it should, you should get 6-9 months life from your shaft anodes. Anything dramtically more or less than that and you should be looking for a reason.

Re: Hull cleaning

Thanks for those (though I realize this is a really old post). Why did you put two zincs right next to each other at the base of the shaft rather than more evenly spaced? Also, were these all new zincs from three months earlier? That seems like a lot of electrolysis in a short time. I wear through one zinc in about six weeks, which has always seemed like a lot given what I've read.

Cannot recommend doing in-water hull cleaning without (at the very least) wearing a hood.
