I'm in the process of seeing what I can find out on the reballasting, but in the process I found this and thought it was interesting:
"Restoring HMS Bounty II
HMS Bounty underwent a major three-phase restoration project from 2001 to 2006 after being purchased by the HMS Bounty Organisation LLC.
The first phase of the refit was to replace the hull, which at the time was so damaged the vessel was taking on 30,000 gallons of water an hour.
From the "for sale" advert:
