Scott-
I had a similar problem 2 years ago. I would fill both tanks and would find after a sail that I would lose a significant amount. However, when a checked for leaks on the mooring, I couldn't find any. Well, to make a long story short, I finally found that I had a leak on the top of my starboard water tank, which only leaked when the boat was heeling. That leak was at a stiffener on the top of the tank, which I think failed due to the excess pressure caused by filling the tanks from the deck fill connections. I removed the starboard tank and got the crack plastic welded, and it hasn't leaked since. I now never cross-connect my tanks, and never fill from the deck fittings unless someone is watching down below to assure that we never fill above the the tank top.
You can check this out on your boat by slowly filling from the deck connections and overfill slightly. If you have cracks on the top, you will see leakage to the bilge or to the cabin sole directly.
If you need to get your tank welded, you can contact:

If you have any questions, don't hesistate to contact me off-line.
