The actual Bounty had about the double of the displacement of the original Bounty.
I think that given that difference in displacement it does not make sense to say that the original plans were followed because the scantlings would have to be different.
If the original scantlings were followed on a ship with a two times the original displacement ...well, then something was very wrong.
Saying this I don't know about the design of this Bounty. I suppose that a naval architect was responsible for that alteration but I never heard nothing about who was or about his competence to do the job.
Anyway I don't see the point in discussing this. Even if the Bounty was a very well built boat, it was still basically a XVIII century designed wooden ship, with limitations that had to do with the 3 centuries old design and the building materials. In any case that boat would not safe sailing an hurricane, so what's the point?
