NO,
Hard to locate where your leaking water really comes from, and your writing tells about the understandable disappointment and frustration you are in. In such situations we tend often to see a bigger problem as is. The H260 is a quite robust boat and I can't think of something like broken down fiberglass or large crags on the ballast tank, especially since your hull appeared to be in perfect shape.
As much I followed water problems being described here, the suspicion pointed often first to the ballast tank, but on the end it was something else. Went through the same; finally I had mainly just a bad sealing rubber plug on the tank under the stair step. I had dyed the tank as well. When heeling, the water run out of the plug down in the boat and gave a wrong impression about the location of the leak, couldn't believe that simple. Some fellow H260 had (also I) small leaks on the compression post foot. As seen in my picture, I sealed around raised fiberglass against the surrounding to keep possible leaking water in both areas from running down on top of the ballast tank or into the bottom of the boat. Work out well for me, never any water issue again.
Have also a good look at all through hull connections and check if your boat has any damage an the bow/deck seal. Putting pieces of paper towels may give you some clues too. Good luck.
