Re: Matt Jefferies and NCC-1017
Based on the dedication plaque alone (and indeed that's all there is to base anything on!), I'd say that Yates pinched or otherwise obtained the dedication plaque of the 23rd century Starfleet cruiser USS Xhosa of Antares class, or at least a good replica thereof, and thought that it would look cool on the wall of her own freighter SS Xhosa of Masai class.
I'm pretty sure that was not Okuda's intention when he made the plaque.
