Give up my stash for cash? Never happen.
As to the weight distribution, that is a simple solution.
If it is down at the bow start sending people on board one by one, walk towards the stern.
When it is balanced add up the weights and note the location. That is how much you need and where.
The ship itself was probably balanced as designed, but changes in decor could easily add up to 250 lbs needed to bring it back into balance.
