The boat is in the water, but I (think) remember it being wet on the
stands before it went in the water last month.

I should have added that the people I paid to winterize the boat did
not. This caused many problems (leaking hot water heater, filters,
pressurizing pump) and I originally thought that was the cause. I
drained all the water system and STILL had the water in the cabin
problem. However, I am wondering if this is related some otehr way.

I have heard people talk of the drain plug. Where is this located?
Could it be possible the winterizing people pulled it and din't put it
back in? I am not familiar with the drain plug at all.

There is a normal water in the aft bilge. My blige compartments aren't
connected.
