Thanks for all of this, Gregg. I think the conclusion that we are coming to is that ENTERPRISE is not #828 (that number most likely belongs to AQUILA.)
I'm not really sure how you come to this conclusion.
I respectfully suggest that you do not change the Registry based upon a few things people post in a web page. No disrespect meant to the posters but how serious was their research? How thorough?
Then someone posts something else, and the Registry gets changed again. And then again and again and there's no traceback other than the web page. Soon no one will know if ANY of it is true. Changes should only occur when there has been serious work done on the new information - at least as thorough as the work done to create the Registry in the first place.
I respectfully suggest you go to the people who put the time and effort into building the Registry and ask them questions:
In the tracing of ENTERPRISE backwards, what hard proof did they have? What evidence did they have? And by proof I do not mean some anonymous entry in the Boston Globe, or hearsay. I mean receipts, bills of sale, municipal documents, notarized documents, taxes paid etc. This is proof:

And right there you can see that Mr. Aldrich did not know the year the boat was built nor it's hull number. That's important information.
If there's a document that shows that HMCo sold hull #828 to Nathaniel Ayer then that is proof.
But even if they did, that doesn't tell you what happened to the boat after that.
Proof like these documents most likely won't exist for every step in the traceback. But one piece of paper connects two owners. Some of the dots will be connected.
The BG article is *NOT* proof nor even evidence. It's a lead, and one seriously worth following up. Where did "Anon" of the article get their info? Were the creators of the Registry aware of the BG article? If so, what did they think about it? Why did they not accept it? What counter evidence do they have? If they rejected it, did they have good reasons to do so?
If they weren't aware of it, that means something, too.
What suppositions and assumptions where they forced to make in the steps of the traceback?
If I was not aware of the answers to those questions I'd be extremely hesitant to alter their work.
Now, would I love it if my boat was truly Gob? Sure. Who wouldn't.
But I'd much rather know the true provenance of the boat. That way I can enjoy her history. But in trying to trace things like this there are bound to be discrepancies, conflicting bits of hearsay, assumptions and supposition.
And I would not make a change based upon some web page entries.
Just my opinion.
