Re: Rust stains at partners?
I suspect the answer in all cases is that something is wrong, and you'll need to pull the mast, inspect, and repair. If that's deck, you may find extensive work to be done. And at the same time, might as well have the mast & fittings inspected, do whatever else can be done while it is down. Replace the bulbs in the masthead lights while they're at hand, too.
It sure looks like rust to me, but I've been surprised before.
