Our trad. stern 47ft boat was built by Stowe Hill Marine about 1989. We have owned her for 12 months or so. There is a noticable list to port which I think has been there since we bought the boat. I'd say that this side of the boat is about two inches lower in the water than the other side. It's been pointed out to me that most of the weight is on the port side i.e. engine and batteries, bed base and mattress, bathroom and pump-out tank, galley and dinette, with only the woodburner to starboard. Is this something we have to live with or could I correct it with ballast? If so, how much and where would it go?
