Water in the bilge is always a fun game.

I’d start with things where you know there’s water…shower dumps (is the pump failing?), shaft seals, and rudder ports. If those are all working properly, check things like faucets and fixtures. Finally, I’d look at leaks like from deck side fittings, windows, etc.

First, clean up the water. Does it come back? How fast? Next, look In every compartment for any “trails.” Takes some investigative work.

I had some mystery water up forward under my shower sump. Everything worked properly and I could find no leaks. Cleaned it up and discovered it only came back after like a weekend onboard. It became a real head-scratcher. In the end, the pump in my shower sump was failing. Just so happened it would be running when I would check it. Replaced the pump and water is gone.
