Interesting though why the ballasting change.
Ahhhh that's how they lightened her!
That's an interesting part of the jigsaw because you remember how there was so many inspection certificates issued this year. And the weigh was different but quite a bit. The passenger ship non inspected the vessel needed to be under a certain deadweight or displacement, don't remember which.
It's not my field at all so it went over my head a bit.
10 tones off the ballast. Hmmm.
UPVs may also include vessels over 100 GTs but less than 300 GTs that carry not more than 12 passengers, with at least one being a passenger for hire. Such vessels are discussed in the Enclosure (3). Please contact the Coast Guard using one of the phone numbers provided on page three of this booklet for any questions regarding such vessels. http://www.uscg.mil/pvs/docs/UPV_JobAid2011.pdf
So they had to get her under the 300 tons.
Remember that as an uninspected vessel and safety breaches the CG finds they can only ADVISE the owners to make good, they can't ENFORCE any requirements or fines!
This said she was 500 tons http://easternyachts.com/bounty/index.htm
Wikipedia says Tonnage: 409 GT. 181 NT
But someone here had the official ships record where the tonnages changed...
So they may have done it so as not to be safety inspected!
