I think I may have a leak in the fresh water tank. From what I can tell it has to be either under the dinette or between the dinette and the galley. Can anyone confirm?
Not familiar with your boat, but I've never run into a water thank that wasn't at least partially accessable through a hatch (often under a berth). It's probably pretty much right below your deck fill.
I have the same boat, the tank is in that area but I found my leak was the shower control in the head. The water tank is molded into the hull and really isn't accessible. If interested, I have the original owners manual from Ocean, for the cost of copying and shipping I'll get you one, it shows the location of everything you'll need.
