Rusty Rigging

[pinckney54]

I recently had my boat re-rigged by a reputable boatyard. (2 months ago) After 2 months of mostly sitting in a marina, the rigging is very noticeably corroded/rusted. As a matter of fact, it's corroded more than the 14 year old rigging that was replaced. It's odd...any idea what would cause this to happen so quickly?

Not all wire is created equal. Nor are fittings. If you aren't in an area where there is a lot of pollution, say downwind from a power plant or something. The chances are that the wire is of lesser quality than that which was replace.
Having said that, it is not unusual to see signs of surface corrosion within two months, especially in southern climates.

Well, I had same on my new boat (so new fittings). Apparently actual market is using cheaper steel from Asia, wich has a slightly different compound on carbon, although all of them could be 316. I found also, that some companies doesn't store SS hardware correctly, or even using incorrect mounting tools that contaminate the material. If your HW is correct 316, just keep it polished, closing surface gaps, and rust will fade away, eventually. I did polish my entire deck fittings, and rust didn't return after 4 months so far.
