Glad I could be of service.

IN my many years with the Coast Guard I saw a lot of boats that had a list (leans to one side) at rest. It was a simple matter that the builder didn't do their homework, what designers call weight and moment calculations. For a boat to sit level you have to have the same amount of weight on both sides. This means actually weighing the stuff you are planning to put on the boat (or getting the weight from the maker) and then adding it all up and seeing if it all comes out even. If it doesn't you have to move things around until it does. Some builders simply don't do this so at launch the boat leans. This may not be dangerous (it can be) and if it's a planing hull the boat may level out at speed if the heel is minor like 1/2 or 1 degree. Adding weight may correct the heel but it causes all kinds of other problems. Number 1. The boat weighs more, therefore displaces more, takes more power to go the same speed and uses more fuel. 2. even more problematic, it changes the stability of the boat. A boat that may have been very stable may now not be stable at large angles of heel, like when you take a huge wave from the side and lean so far over your passenger start falling out of their seats. Adding weight is not a good solution. removing weight can help but it might make the boat more tender. The best solution is to move stuff around until the boat sits level. This can be very hard to do becasue it means moving equipment, sometimes structure, and literally requires redesigning the boat. So the builder takes the asy way out and adds weight.
Of course there may be another problem. When the boat was launched it may not have sat "on it's lines" meaning it didn't float at the designed waterline and actually needed extra weight to bring it down to the waterline. Or it could have been down at the bow or stern and need weight to even it fore and at. All of these are indicators that the designer didn't do the math.
If it truly bothers you and you don't feel it is safe, then take out the weight and start moving heavy stuff around, Batteries, generators, appliances, etc. Especially stuff that is up high, like hot tubs. Why would any one put a hot tub full of several thousand pounds of water on the upper deck?? Beats me but some houseboat builders do that. On the other hand if it doesn't bother you and the boat doesn't have any quirks (like slow, long rolls, or snappy rolls that knock your teeth out) then leave it alone. Also check that you aren't storing stuff up higher that could be down low. I once looked at a cruiser that the owner complained about, that seemed very tender. He had 21 cases of soda and beer on the flying bridge. When we moved all that weight down low the boat was fine.
