I think the title pretty much says it all. I'm a mechanical engineer working in the marine industry so I have a basic understanding of corrosion and cathodic protection, but that is it. I'm trying to find information or a lead on how to calculate the number/size/amount of zincs I need to protect an aluminum hull in sea water?
I've spent time researching this topic and all I can find is how to test the hull once it is in the water and what ranges are good. We will run those tests once in the water, but it takes time and there are other factors that concern the credibility of the results until after the boat leaves the shipyard. In the past we've built FRP and Steel hulls so having too much isn't as great of a concern. From my research I have found that for aluminum hulls it is possible to have too much so it is worth spending the time upfront.
Thanks in advance
