Not rust, but what?

After the last two rains, found this stain oozing out of a snap screwed into the deck for the skylight sun cover. It cleans up, but is it rotting core or what? Reddish brown but definitely not rust.

You know those horror movies where blood oozes out of walls in haunted houses.

Well, nothing coming out of the deck after the last rain, but this definitely can’t be good. Forward cabin starboard side, deck stain was on the port side.

open it up, to see how far the damage extends. bummer. It isn't necessarily a death sentence, but what you are pointing out seems like a lot of saturation

Water coming out of the AC outlet is not a good sign. Pull the outlet and check for corrosion. With that much water, there must be a deck leak somewhere. A stanchion or chain plate perhaps?
