...AC [] drain running into the "dry" bilge...

I have that covered. My installer did the same, running the condensate
drain to the bilge rather than a few more feet - and difficulty - to the
shower sump. I just built a sump out of a gallon Tupperware-like covered
container with a small pump and floatswitch. It didn't work initially; the
3/4" line to the throughhull had enough volume to take three inches of sump
water without putting any overboard; when the switch shut the pump down, the
water just ran back to the sump. I reduced the tubing to 3/8" at the pump
and back to 3/4" at the throughhull so, now, it shoots a very nice thin
stream out of the center of the throughhull - and almost completely empties
the sump. Works well and I have a "dry" bilge - when it isn't rainy season.

I've looked for other moisture sources and don't see anything that could
reasonably wet the bottom edge of the carpet (I guess "cabin liner" is a
better term). Thanks for the vinegar tip; I'll try that.

Happy Thanksgiving, Frank.
