Aaah the listing thing.
Top Hat hulls were made in two halves, neither of which were exactly the same, and then joined together.
This can contribute to a list BUT...
Check the vertical measurement from your anti-fouling to your deck, compare each side.
This, if different can create an illusion that your boat is leaning over.
As some have said your mast may not be vertical also. Check your stays not the fore/back stays.
Top Hats as a rule did not have adjustable backstays, but those with splitters can, as Bluemoon said, install a block tensioner.
I did have one but removed it as I could not see any benefits when cruising. Racing, maybe?

As for placing weights, batteries etc, within, its best to start with an empty boat so you can see the effects as you load them onboard.
From my experience the perceived list make no difference when sailing.
