Dust and moisture in a bilge are always going to reappear as sludge. Frequent cleaning is required to avoid.

Would love to see some pics. I have a small compartment that holds some water and I've wanted to just pump it to my low bilge. Arid Bilge is overkill.

A dry vac is a cute idea, but not going to solve some problems. You can't stop water coming down the mast and, if you have an issue with some limber holes blocking the bottom 1/8" of water from flowing, it will almost always be wet. Requires mechanical automated solution. Not manual.
