Fortunately our yard doesn't get involved with stepping and unstepping masts so it's 100% my discretion.
I know a guy who does stainless. I was thinking about getting him to check out the plates and quote me on new ones made to spec, except instead of 1/2" thickness throughout, I would ask for the below deck portion to be 1/4" or 3/8" thickness. I'm under the impression that stainless is much stronger and can be thinner to achieve the equivalent strength to the aluminum plates. I'm not an engineer, but I'd sail with that setup. If these aluminum plates are fine as is for another 5 years or so I can put this job off. I've seen much worse corrosion.
