Glastron GX255 Bowrider - head compartment

[DayBoater2007]

Does anyone else who owns this boat find that the floor of the porta potti compartment (not where the porta potti actually sits, but right in front of it, where you would put your feet if you were sitting on the potti) gets soaking wet for no apparent reason, after a heavy rain, with the boat still covered? I can't seem to detect any water coming into the top of the head compartment anywhere, and there is no water on the walls. I am guessing that somehow the water is coming up from the bottom, in the hull somewhere.

It's an occasional, but recurring issue. No, the boat is not sinking, had it three years, no issue of the sort, it's reliably out behind the house in the water each day, no issue.
